Android ImageButton - determine what resource is currently set
12,833
Solution 1
Just use setTag()
and getTag()
to associate and retrieve custom data for your ImageView
.
Solution 2
You could define your own class as a child of ImageButton
, add a private int variable and set it when setImageResource(int)
is called. Something like:
public class MyImageButton extends ImageButton {
private int mImageResource = 0;
@Override
public void setImageResource (int resId) {
mImageResource = resId;
super.setImageResource(resId);
}
public int getImageResource() {
return mImageResource;
}
}
I didn't test it, but you get the idea - then you can call getImageResource() on your button, assuming it has been previously set with setImageResource().

Is there a way I can find what resource a particular ImageButton is set to, at any given time?
For eg: I have an ImageButton that I set to
R.drawable.btn_on
onCreate. Later, at some point, the ImageButton gets set toR.drawable.btn_off
. I want to be able to check what resource the ImageButton is set to in my code.Thanks Chris
