Thanks to dextor answer, I could figure out this answer.
I've used the FocusChangeListener and added animation states to change the size of the view:
static class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(final View root) {
// bind views
// ...
// bind focus listener
root.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// run scale animation and make it bigger
Animation anim = AnimationUtils.loadAnimation(context, R.anim.scale_in_tv);
root.startAnimation(anim);
anim.setFillAfter(true);
} else {
// run scale animation and make it smaller
Animation anim = AnimationUtils.loadAnimation(context, R.anim.scale_out_tv);
root.startAnimation(anim);
anim.setFillAfter(true);
}
}
});
}
And the code for the anims:
scale_in_tv:
scale_out_tv:
