How can I remove a button in Android, or make it invisible?

Set button visibility to GONE (button will be completely "removed" -- the buttons space will be available for another widgets) or INVISIBLE (button will became "transparent" -- its space will not be available for another widgets):

View b = findViewById(R.id.button);
b.setVisibility(View.GONE);

or in xml:

<Button ... android:visibility="gone"/>

First make the button invisible in xml file.Then set button visible in java code if needed.

Button resetButton=(Button)findViewById(R.id.my_button_del);
resetButton.setVisibility(View.VISIBLE); //To set visible

Xml:

<Button
android:text="Delete"
android:id="@+id/my_button_del"
android:layout_width="72dp" 
android:layout_height="40dp"
android:visibility="invisible"/>

To remove button in java code:

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(View.GONE);

To transparent Button in java code:

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(View.INVISIBLE);

To remove button in Xml file:

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>

To transparent button in Xml file:

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible"/>

button.setVisibility(View.GONE);

This view is visible.

button.setVisibility(View.VISIBLE);

This view is invisible, and it doesn't take any space for layout purposes.

button.setVisibility(View.GONE); 

But if you just want to make it invisible:

button.setVisibility(View.INVISIBLE);

use setVisibility in button or imageViwe or .....
To remove button in java code:

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(Button.GONE);

To transparent Button in java code

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(Button.INVISIBLE);
				

You should make you button xml code like below:

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>

hidden:
visibility: gone
show:
visibility: invisible
visibility: visible

button.setVisibility(button.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);

Makes it visible if invisible and invisible if visible

IF you want to make invisible button, then use this:

<Button ... android:visibility="gone"/>

View.INVISIBLE:

Button will become transparent. But it taking space.

View.GONE

Button will be completely remove from the layout and we can add other widget in the place of removed button.

View controls (TextView, EditText, Button, Image, etc) all have a visibility property. This can be set to one of three values:

Visible - Displayed

android:visibility="visible"

Invisible - Hidden but space reserved

android:visibility="invisible"

Gone - Hidden completely

android:visibility="gone"

To set the visibility in code use the public constant available in the static View class:

Button button1 = (TextView)findViewById(R.id.button1);
button1.setVisibility(View.VISIBILE);

To completely remove a button from its parent layout:

((ViewGroup)button.getParent()).removeView(button);

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/activity_register_header"
    android:minHeight="50dp"
    android:orientation="vertical"
    android:visibility="gone" />

Try This Code

Visibility works fine in this code

In order to access elements from another class you can simply use

findViewById(R.id.**nameOfYourelementID**).setVisibility(View.GONE); 

If you want to make your button invisible such that it doesn't take any space in the layout, then add this in your Java code:

Button button = (Button)findViewById(R.id.button);
button.setVisibility(View.GONE);

Or in XML: android:visibility="gone"

If you want to make your button invisible such that it still takes up space in your layout then replace "View.GONE" with "View.INVISIBLE" in your java code or replace "gone" with "invisible" in your xml code.

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(8);

Try This Code :

button.setVisibility(View.INVISIBLE);
