How do you set the max number of characters for an EditText in Android?

How do you set the max number of characters for an Android EditText input? I see setMaxLines, setMaxEMS, but nothing for the number of characters.

In XML you can add this line to the EditText View where 140 is the maximum number of characters:

android:maxLength="140"

Dynamically:

editText.setFilters(new InputFilter[] { new InputFilter.LengthFilter(MAX_NUM) });

Via xml:

<EditText
    android:maxLength="@integer/max_edittext_length"

You can use a InputFilter, that's the way:

EditText myEditText = (EditText) findViewById(R.id.editText1);
InputFilter[] filters = new InputFilter[1];
filters[0] = new InputFilter.LengthFilter(10); //Filter to 10 characters
myEditText .setFilters(filters);

I always set the max like this:

    <EditText
        android:id="@+id/edit_blaze_it
        android:layout_width="0dp"
        android:layout_height="@dimen/too_high"

    <!-- This is the line you need to write to set the max-->
        android:maxLength="420"
        />

It is working for me.

	etMsgDescription.setFilters(new InputFilter[] {new InputFilter.LengthFilter(maximum_character)});
	
	etMsgDescription.addTextChangedListener(new TextWatcher() {
		
		@Override
		public void onTextChanged(CharSequence s, int start, int before, int count) {
			
			tvCharacterLimite.setText(" "+String.valueOf(maximum_character - etMsgDescription.getText().length()));
		}
		
		@Override
		public void beforeTextChanged(CharSequence s, int start, int count,
				int after) {
			// TODO Auto-generated method stub
			
		}
		
		@Override
		public void afterTextChanged(Editable s) {
			// TODO Auto-generated method stub
			
		}
	});

   <EditText
        android:id="@+id/edtName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter device name"
        android:maxLength="10"
        android:inputType="textFilter"
        android:singleLine="true"/>

InputType has to set "textFilter"

        android:inputType="textFilter"

use this function anywhere easily:

 public static void setEditTextMaxLength(EditText editText, int length) {
    InputFilter[] FilterArray = new InputFilter[1];
    FilterArray[0] = new InputFilter.LengthFilter(length);
    editText.setFilters(FilterArray);
  }

Kotlin way

editText.filters = arrayOf(InputFilter.LengthFilter(maxLength))

It worked for me this way, it's the best I've found. It is for a max length of 200 characters

editObservations.addTextChangedListener(new TextWatcher() {

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        if (editObservations.getText().length() >= 201){
                String str = editObservations.getText().toString().substring(0, 200);
                editObservations.setText(str);
                editObservations.setSelection(str.length());
        }
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count,
                                          int after) {
    }

    @Override
    public void afterTextChanged(Editable s) {
    }
});

Obviously you can use maxLength in xml or InputFilter.LengthFilter as answered above. But for me in some cases, it was not enough. I created a class for more flexible settings of EditText: https://github.com/devapro/NumberWatcher It is implementation only for numbers input, but you can change it for any of the types.

it doesn't work from XML with maxLenght I used this code, you can limit the number of characters

> String editorName = mEditorNameNd.getText().toString().substring(0, Math.min(mEditorNameNd.length(), 15));

You could add a validation hook to a submit or change event.

if (EditText.length() <=10){
            Toast.makeText(MainAcitvity.this, "Enter Valid Number", Toast.LENGTH_SHORT).show();
            contact.setError("Enter Valid");
            return false;
        }
