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

How to&Answers:

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"/>

Answer:

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);

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

To remove button in Xml file:

<Button
android:id="@+id/btn"

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

visibility: invisible
visibility: visible

Answer:

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

Makes it visible if invisible and invisible if visible

Answer:

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);

Answer:

To completely remove a button from its parent layout:

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

Answer:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/activity_register_header"
