How to stretch the click area of ​​a button, but not stretch the background?

Question

Java

How to do it like in the diagram below?

There is a big button, half the screen. The click area should be half the screen. The code:

<Button
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/button_play"
            android:id="@+id/button"
            android:onClick="start"/>

But the background image is stretched to full screen (it seems to be clear why). I can't change the button parameters for 'wrap_content', the click area is reduced to the size of the image.
I'm sure the solution will turn out to be quite simple, but until you know it, and don't know how to google it, it seems complicated. Thanks in advance!

Answer 1

I remade the Button into an ImageButton, made the picture the android:src attribute, and made an empty transparent picture on the background.

Answer 2

For such cases, TouchDelegate is used .

Answer 3

set the android:padding attribute.
