Question

In one of my activities I have an ImageButton that on click changes the background resource by using setBackgroundResource(). I works fine in that activity but when I leave that activity and come back to it the button has changed back to its default background that was set in the XML. Is there a way to permanently set the background resource to something until the button is clicked again?

Answer 1

You need to store the value on the image button in a static variable or SharedPreferences,

For example declare a variable

public static int bgresource;

now on the img button click

if(something) {
bgresource = R.drawable.img1
} else {
bgresource = R.drawable.img2
}

mylayout.setBackgroundResource(bgresource);

and also do the following in onResume() of the activity:

mylayout.setBackgroundResource(bgresource);
