Question

Instead of have to call separate method for each button, would it be possible to just use one method and check which button it was that was clicked by it’s id?

I’m using the simple way like android:onClick="activateButtons"

public void activateButtons(View v)
{
    if(?? == btn_1)
    {
    Code for button with ID = btn_1
    }
    if(?? == btn_1)
    {
    Code for button with ID = btn_2
    }
}

You can do that if you tag the buttons with an Id. Set the android:id="@+id/yourbuttonid" in the xml file. Then do if(v.getId() == R.id.yourbuttonid) in the onClick method.
