How to switch between hide and view password

Is there a clever way to let the user switch between hide and view password in an android EditText? A number of PC based apps let the user do this.

It is really easy to achieve since the Support Library v24.2.0.

What you need to do is just:

1. Add the design library to your dependecies

    dependencies {
         compile "com.android.support:design:24.2.0"
    }
   

2. Use TextInputEditText in conjunction with TextInputLayout

    <android.support.design.widget.TextInputLayout
        android:id="@+id/etPasswordLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:passwordToggleEnabled="true"
        android:layout_marginBottom="@dimen/login_spacing_bottom">
   
        <android.support.design.widget.TextInputEditText
            android:id="@+id/etPassword"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/fragment_login_password_hint"
            android:inputType="textPassword"/>
    </android.support.design.widget.TextInputLayout>
   

The passwordToggleEnabled attribute will do the job!

3. In your root layout don't forget to add xmlns:app="http://schemas.android.com/apk/res-auto"

4. You can customize your password toggle by using:

app:passwordToggleDrawable - Drawable to use as the password input visibility toggle icon.
app:passwordToggleTint - Icon to use for the password input visibility toggle.
app:passwordToggleTintMode - Blending mode used to apply the background tint.

More details in TextInputLayout documentation.

For AndroidX

• Replace android.support.design.widget.TextInputLayout with com.google.android.material.textfield.TextInputLayout

• Replace android.support.design.widget.TextInputEditText with com.google.android.material.textfield.TextInputEditText

You can dynamically change the attributes of a TextView. If you would set the XML Atrribute android:password to true the view would show dots if you set it to false the text is shown.

With the method setTransformationMethod you should be able to change this attributes from code. (Disclaimer: I have not tested if the method still works after the view is displayed. If you encounter problems with that leave me a comment for me to know.)

The full sample code would be

yourTextView.setTransformationMethod(new PasswordTransformationMethod());

to hide the password. To show the password you could set one of the existing transformation methods or implement an empty TransformationMethod that does nothing with the input text.

yourTextView.setTransformationMethod(new DoNothingTransformation());

To show the dots instead of the password set the PasswordTransformationMethod:

yourEditText.setTransformationMethod(new PasswordTransformationMethod());

of course you can set this by default in your edittext element in the xml layout with

android:password

To re-show the readable password, just pass null as transformation method:

yourEditText.setTransformationMethod(null);

To show:

editText.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

To hide:

editText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

After each of these the cursor is reset, so:

editText.setSelection(editText.length());

You can use app:passwordToggleEnabled="true"

here is example given below

<android.support.design.widget.TextInputLayout
        android:id="@+id/password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:passwordToggleEnabled="true"
        android:textColorHint="@color/colorhint"
        android:textColor="@color/colortext">

I had the same issue and it is very easy to implement.

All you have to do is wrap your EditText field in a (com.google.android.material.textfield.TextInputLayout) and in that add ( app:passwordToggleEnabled="true" ).

This will show the eye in the EditText field and when you click on it the password will appear and disappear when clicked again.

<com.google.android.material.textfield.TextInputLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:textColorHint="#B9B8B8"
                app:passwordToggleEnabled="true">

                <EditText
                    android:id="@+id/register_password"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_marginLeft="24dp"
                    android:layout_marginRight="44dp"
                    android:backgroundTint="#BEBEBE"
                    android:hint="Password"
                    android:inputType="textPassword"
                    android:padding="16dp"
                    android:textSize="18sp" />
            </com.google.android.material.textfield.TextInputLayout>

Use checkbox and change the input type accordingly.

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    int start,end;
    Log.i("inside checkbox chnge",""+isChecked);
    if(!isChecked){
        start=passWordEditText.getSelectionStart();
        end=passWordEditText.getSelectionEnd();
        passWordEditText.setTransformationMethod(new PasswordTransformationMethod());;
        passWordEditText.setSelection(start,end);
    }else{
        start=passWordEditText.getSelectionStart();
        end=passWordEditText.getSelectionEnd();
        passWordEditText.setTransformationMethod(null);
        passWordEditText.setSelection(start,end);
    }
}

private boolean isPasswordVisible;

private TextInputEditText firstEditText;

...

firstEditText = findViewById(R.id.et_first);

...

    private void togglePassVisability() {
    if (isPasswordVisible) {
        String pass = firstEditText.getText().toString();
        firstEditText.setTransformationMethod(PasswordTransformationMethod.getInstance());
        firstEditText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        firstEditText.setText(pass);
        firstEditText.setSelection(pass.length());           
    } else {
        String pass = firstEditText.getText().toString();
        firstEditText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
        firstEditText.setInputType(InputType.TYPE_CLASS_TEXT);
        firstEditText.setText(pass);
        firstEditText.setSelection(pass.length());
    }
    isPasswordVisible= !isPasswordVisible;
}

At first this is the screen loaded with an image vector asset visibility

on click it will change to this image visibility off

Java code for button operation

public void ShowHidePass(View view) {

    if(view.getId()==R.id.show_pass_btn){
        if(edit_password.getTransformationMethod().equals(PasswordTransformationMethod.getInstance())){
            ((ImageView)(view)).setImageResource(R.drawable.ic_visibility_off);
            //Show Password
            edit_password.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
        }
        else{
            ((ImageView)(view)).setImageResource(R.drawable.ic_visibility);
            //Hide Password
            edit_password.setTransformationMethod(PasswordTransformationMethod.getInstance());
        }
    }
}
  

It's work for me.This will help you definitely

showpass.setOnCheckedChangeListener(new OnCheckedChangeListener() {
			
			@Override
			public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
					if(!isChecked){

					// show password
					password_login.setTransformationMethod(PasswordTransformationMethod.getInstance());
					
					Log.i("checker", "true");
				}
					
				else{
					Log.i("checker", "false");
					
					 // hide password
	password_login.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
				}
					
			}
		});

I feel I want answer this question even there some good answers ,

according to documentation TransformationMethod do our mission

> TransformationMethod > > TextView uses TransformationMethods to do things like replacing the > characters of passwords with dots, or keeping the newline characters > from causing line breaks in single-line text fields.

Notice I use butter knife, but its the same if user check show password

@OnCheckedChanged(R.id.showpass)
    public void onChecked(boolean checked){
        if(checked){
            et_password.setTransformationMethod(null);
        }else {
            et_password.setTransformationMethod(new PasswordTransformationMethod());
            
        }
       // cursor reset his position so we need set position to the end of text
        et_password.setSelection(et_password.getText().length());
    }

I'm able to add the ShowPassword / HidePassword code with just a few lines, self-contained in a block:

protected void onCreate(Bundle savedInstanceState) {
	...
    etPassword = (EditText)findViewById(R.id.password);
    etPassword.setTransformationMethod(new PasswordTransformationMethod()); // Hide password initially

    checkBoxShowPwd = (CheckBox)findViewById(R.id.checkBoxShowPwd);
    checkBoxShowPwd.setText(getString(R.string.label_show_password)); // Hide initially, but prompting "Show Password"
    checkBoxShowPwd.setOnCheckedChangeListener( new CompoundButton.OnCheckedChangeListener() {
        public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
            if (isChecked) {
                etPassword.setTransformationMethod(null); // Show password when box checked
                checkBoxShowPwd.setText(getString(R.string.label_hide_password)); // Prompting "Hide Password"
            } else {
                etPassword.setTransformationMethod(new PasswordTransformationMethod()); // Hide password when box not checked
                checkBoxShowPwd.setText(getString(R.string.label_show_password)); // Prompting "Show Password"
            }
        }
    } );
	...

In very simple form:

private fun updatePasswordVisibility(editText: AppCompatEditText) {
        if (editText.transformationMethod is PasswordTransformationMethod) {
            editText.transformationMethod = null
        } else {
            editText.transformationMethod = PasswordTransformationMethod()
        }
        editText.setSelection(editText.length())
    }

Hope it helps.

private int passwordNotVisible=1; 
  @Override
  protected void onCreate(Bundle savedInstanceState) {
 showPassword = (ImageView) findViewById(R.id.show_password);
    showPassword.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            EditText paswword = (EditText) findViewById(R.id.Password);
            if (passwordNotVisible == 1) {
                paswword.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
                passwordNotVisible = 0;
            } else {

                paswword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                passwordNotVisible = 1;
            }


            paswword.setSelection(paswword.length());

        }
    });
}

You can SHOW/HIDE password using this below code:

XML CODE:

<EditText
        android:id="@+id/etPassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="21dp"
        android:layout_marginTop="14dp"
        android:ems="10"
        android:inputType="textPassword" >
        <requestFocus />
    </EditText>
    <CheckBox
        android:id="@+id/cbShowPwd"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/etPassword"
        android:layout_below="@+id/etPassword"
        android:text="@string/show_pwd" />

JAVA CODE:

EditText mEtPwd;
CheckBox mCbShowPwd;


mEtPwd = (EditText) findViewById(R.id.etPassword);
mCbShowPwd = (CheckBox) findViewById(R.id.cbShowPwd);
        
mCbShowPwd.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // checkbox status is changed from uncheck to checked.
        if (!isChecked) {
            // show password
            mEtPwd.setTransformationMethod(PasswordTransformationMethod.getInstance());
        } else {
            // hide password
            mEtPwd.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
        }
    }
});

Try this:

First define a flag as global like this:

private boolean isShowPassword = false;

And set listener to handle tap on show and hide password button:

imgPassword.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (isShowPassword) {
                    etPassword.setTransformationMethod(new PasswordTransformationMethod());
                    imgPassword.setImageDrawable(getResources().getDrawable(R.drawable.ic_eye_hide));
                    isShowPassword = false;
                }else{
                    etPassword.setTransformationMethod(null);
                    imgPassword.setImageDrawable(getResources().getDrawable(R.drawable.ic_eye_show));
                    isShowPassword = true;
                }
            }
        });

Did you try with setTransformationMethod? It's inherited from TextView and want a TransformationMethod as a parameter.

You can find more about TransformationMethods here.

It also has some cool features, like character replacing.

Try https://github.com/maksim88/PasswordEditText project at github. You dont even need to change your Java code using it. Just change

EditText

tag to

com.maksim88.passwordedittext.PasswordEditText

in your XML file.

show and hide password Edit_Text with check Box

}// end class

What I did was to

1. Create an edit text view and a normal text view
2. Make them overlap with each other by using constraint layout (just like Facebook app login screen)
3. Attach an onClickListener to the normal text view so that it changes the input type of the edit text view accordingly (Visible / Non-visible)

Hope it helps :)

Here is my solution without using TextInputEditText and Transformation method.

XML

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

Java Code

boolean VISIBLE_PASSWORD = false;  //declare as global variable befor onCreate() 
loginPassword = (EditText)findViewById(R.id.loginPassword);
loginPassword.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            final int DRAWABLE_TOP = 1;
            final int DRAWABLE_RIGHT = 2;
            final int DRAWABLE_BOTTOM = 3;

            if (event.getAction() == MotionEvent.ACTION_UP) {
                if (event.getRawX() >= (loginPassword.getRight() - loginPassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {

                        loginPassword.setCompoundDrawablesWithIntrinsicBounds(R.drawable.ic_lock_outline_black_24dp, 0, R.drawable.ic_visibility_black_24dp, 0);
                    }
                    return false;

According to this source, if you have migrated your project to AndroidX, then you can replace

compile "com.android.support:design:24.2.0"

with

implementation "com.google.android.material:material:1.0.0"

Then all you have to do is to put the code below to your layout file:

<com.google.android.material.textfield.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:passwordToggleEnabled="true"
    android:hint="@string/hint_text">

  <com.google.android.material.textfield.TextInputEditText
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

</com.google.android.material.textfield.TextInputLayout>

More information about material TextInputLayout can be found here.

To this source, it is recommended to migrate to AndroidX from Android Support Library:

> AndroidX is the open-source project that the Android team uses to > develop, test, package, version and release libraries within Jetpack. > > AndroidX is a major improvement to the original Android Support > Library. Like the Support Library, AndroidX ships separately from the > Android OS and provides backwards-compatibility across Android > releases. AndroidX fully replaces the Support Library by providing > feature parity and new libraries. In addition AndroidX includes the > following features: > > All packages in AndroidX live in a consistent namespace starting with > the string androidx. The Support Library packages have been mapped > into corresponding androidx.* packages. For a full mapping of all the > old classes and build artifacts to the new ones, see the Package > Refactoring page. > > Unlike the Support Library, AndroidX packages are separately > maintained and updated. The androidx packages use strict Semantic > Versioning starting with version 1.0.0. You can update AndroidX > libraries in your project independently. > > All new Support Library development will occur in the AndroidX > library. This includes maintenance of the original Support Library > artifacts and introduction of new Jetpack components.

1 - Make a selector file "show_password_selector.xml"

<selector xmlns:android="http://schemas.android.com/apk/res/android">
	<item android:drawable="@drawable/pwd_hide"
          android:state_selected="true"/>
	<item android:drawable="@drawable/pwd_show"
          android:state_selected="false" />
 </selector>

2 - Aet "show_password_selector" file into imageview.

<ImageView
	android:id="@+id/iv_pwd"
	android:layout_width="@dimen/_35sdp"
	android:layout_height="@dimen/_25sdp"
	android:layout_alignParentRight="true"
	android:layout_centerVertical="true"
 	android:layout_marginRight="@dimen/_15sdp"
	android:src="@drawable/show_password_selector" />

3 - Put below code in java file.

iv_new_pwd.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (iv_new_pwd.isSelected()) {
            iv_new_pwd.setSelected(false);
            Log.d("mytag", "in case 1");
            edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT);
        } else {
            Log.d("mytag", "in case 1");
            iv_new_pwd.setSelected(true);
            edt_new_pwd.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
        }
    }
});

You have to ask if the current text is already shown with dots, the function PasswordTransformationMethod.getInstance() allow you to do that.

This is my funtion in kotlin:

        fun hideAndShowPassword(editText: EditText, indicator: ImageView) {

        if (editText.transformationMethod == PasswordTransformationMethod.getInstance()) {
            editText.transformationMethod = HideReturnsTransformationMethod.getInstance()
            indicator.setImageDrawable(
                ContextCompat.getDrawable(
                    editText.context,
                    R.drawable.eye
                )
            )
            indicator.imageTintList =
                ContextCompat.getColorStateList(editText.context, R.color.colorTintIcons)
        } else {
            editText.transformationMethod = PasswordTransformationMethod.getInstance()
            indicator.setImageDrawable(
                ContextCompat.getDrawable(
                    editText.context,
                    R.drawable.eye_off
                )
            )
            indicator.imageTintList =
                ContextCompat.getColorStateList(editText.context, R.color.colorTintIcons)
        }

        editText.setSelection(editText.text.length)
    }

I used a OnClickListener() which is associated to the button that I want to use as toogle.

private EditText email_et, contraseña_et;
protected void onCreate(Bundle savedInstanceState) {
....
contraseña_et = (EditText) findViewById(R.id.contraseña_et);
....
vercontra_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int inputType = contraseña_et.getInputType();
            if (inputType == 129){
                contraseña_et.setInputType(1);
            } else {
                contraseña_et.setInputType(129);
            }
            contraseña_et.setSelection(contraseña_et.getText().length());
        }
    });

Reading docs, the int value seems to be different so I debugged to find the correct values, it's working awesome and is a little bit easier this way.

[Contraseña is password in spanish, btw]

In XML do like this

    <LinearLayout
          android:layout_height="wrap_content"
          android:layout_width="fill_parent"
          android:orientation="vertical"
          >
          <RelativeLayout
              android:id="@+id/REFReLayTellFriend"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="horizontal"
              >
          <EditText
              android:id="@+id/etpass1"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:background="@android:color/transparent"
              android:bottomLeftRadius="10dp"
              android:bottomRightRadius="50dp"
              android:fontFamily="@font/frutiger"
              android:gravity="start"
              android:inputType="textPassword"
              android:hint="@string/regpass_pass1"
              android:padding="20dp"
              android:paddingBottom="10dp"
              android:textColor="#000000"
              android:textColorHint="#d3d3d3"
              android:textSize="14sp"
              android:topLeftRadius="10dp"
              android:topRightRadius="10dp"/>
              <ImageButton
                  android:id="@+id/imgshowhide1"
                  android:layout_width="40dp"
                  android:layout_height="20dp"
                  android:layout_marginTop="20dp"
                  android:layout_marginRight="10dp"
                  android:background="@drawable/showpass"
                  android:layout_alignRight="@+id/etpass1"/>
          </RelativeLayout>    

 boolean show=true;
 //on image click inside password do this
 if(show){
                imgshowhide2.setBackgroundResource(0);
                imgshowhide2.setBackgroundResource(R.drawable.hide);
                etpass2.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
                etpass2.setSelection(etpass2.getText().length());

                show=false;
            }else{
                imgshowhide2.setBackgroundResource(0);
                imgshowhide2.setBackgroundResource(R.drawable.showpass);
                //etpass1.setInputType(InputType.TYPE_TEXT);
                etpass2.setInputType(InputType.TYPE_CLASS_TEXT |
                        InputType.TYPE_TEXT_VARIATION_PASSWORD);
                etpass2.setSelection(etpass2.getText().length());
                show=true;
            }

My Kotlin extension . write once use everywhere

fun EditText.tooglePassWord() {
this.tag = !((this.tag ?: false) as Boolean)
this.inputType = if (this.tag as Boolean)
    InputType.TYPE_TEXT_VARIATION_PASSWORD
else
    (InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD)

this.setSelection(this.length()) }

You can keep this method in any file and use it everywhere use it like this

ivShowPassword.click { etPassword.tooglePassWord() }

where ivShowPassword is clicked imageview (eye) and etPassword is Editext

A good solution. Set up a button, then use this code:

public void showPassword(View v)
{

    TextView showHideBtnText = (TextView) findViewById(R.id.textView1);

    if(showHideBtnText.getText().toString().equals("Show Password")){
        password.setTransformationMethod(null);
        showHideBtnText.setText("Hide");
    } else{
        password.setTransformationMethod(new PasswordTransformationMethod());
        showHideBtnText.setText("Show Password");
    }


}

Add this method:

fun EditText.revertTransformation() {
    transformationMethod = when(transformationMethod) {
        is PasswordTransformationMethod -> SingleLineTransformationMethod.getInstance()
        else -> PasswordTransformationMethod.getInstance()
    }
}

Call it will switch between input type state (you may change the Single-Line transformation to your favorite). Usage example:

editText.revertTransformation()

Try this:

passwordEditText.setInputType(1);

Or

passwordEditText.setInputType(InputType.TYPE_CLASS_TEXT);

Use the below code

    val hidePasswordMethod = PasswordTransformationMethod()
    showOrHidePasswordButton.setOnClickListener {
        passwordEditText.apply {
            transformationMethod =
                if (transformationMethod is PasswordTransformationMethod) 
                   null //shows password
               else 
                   hidePasswordMethod //hides password
        }
    }

and make sure you add this to your password edittext in layout

    android:inputType="textPassword"

If you want a simple solution you can use this extension of Android's EditText go to this link for more info: https://github.com/scottyab/showhidepasswordedittext

Add this to your build.gradle: implementation 'com.github.scottyab:showhidepasswordedittext:0.8'

Then change your EditText in your XML file.

From:

To:

That's all.

Note: You can't see it while in XML Design, try to run it in your Emulator or Physical Device.

It seems that input_layout.isPasswordVisibilityToggleEnabled = true is deprecated. And in my case I did it that way in Kotlin:

input_edit_text.inputType = TYPE_CLASS_TEXT or TYPE_TEXT_VARIATION_PASSWORD
input_layout.endIconMode = END_ICON_PASSWORD_TOGGLE

Where input_edit_text is com.google.android.material.textfield.TextInputEditText and input_layout is com.google.android.material.textfield.TextInputLayout. Of course you should import these asl well:

import android.text.InputType.TYPE_CLASS_TEXT
import android.text.InputType.TYPE_TEXT_VARIATION_PASSWORD
import com.google.android.material.textfield.TextInputLayout.END_ICON_PASSWORD_TOGGLE

My may customize the icon with provided methods as these:

 input_layout.endIconDrawable = ...
 input_layout.setEndIconOnClickListener {  }
 input_layout.setEndIconOnLongClickListener(...)

Just create a checkbox in Xml file

and then simple write this function in java code

checkbox = findViewById(R.id.checkbox);
        checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked){

                if (isChecked) {
                    password.setTransformationMethod(null);
                }
                else{
                    password.setTransformationMethod(new PasswordTransformationMethod());
                }
            }

        });

if (inputPassword.getTransformationMethod() == PasswordTransformationMethod.getInstance()) {
 //password is visible
                inputPassword.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
            }
else if(inputPassword.getTransformationMethod() == HideReturnsTransformationMethod.getInstance()) {
 //password is hidden
                inputPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());
            }
