Issue

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

Solution

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"/>
