Easy way to setOnClickListener() on all Activity Buttons

Question

New to android development, but not entirely new to Java. Right now my code inside the onCreate() method is quite basic:

    Button b1 = (Button) findViewById(R.         


        

Answer 1

in onCreate call get the root layout

ViewGroup rootLayout=(ViewGroup) findViewById(R.id.root_layout);

then pass it to this method, (using recursive for deep search for buttons)

public void setAllButtonListener(ViewGroup viewGroup) {

    View v;
    for (int i = 0; i < viewGroup.getChildCount(); i++) {
        v = viewGroup.getChildAt(i);
        if (v instanceof ViewGroup) {
            setAllButtonListener((ViewGroup) v);
        } else if (v instanceof Button) {
            ((Button) v).setOnClickListener(myButtonsListener);
        }
    }
}

good luck
