How to handle button clicks using the XML onClick within Fragments

Question

Pre-Honeycomb (Android 3), each Activity was registered to handle button clicks via the onClick tag in a Layout\'s XML:

android:onClick=\"m         


        

Answer 1

In my use case, I have 50 odd ImageViews I needed to hook into a single onClick method. My solution is to loop over the views inside the fragment and set the same onclick listener on each:

    final View.OnClickListener imageOnClickListener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            chosenImage = ((ImageButton)v).getDrawable();
        }
    };

    ViewGroup root = (ViewGroup) getView().findViewById(R.id.imagesParentView);
    int childViewCount = root.getChildCount();
    for (int i=0; i < childViewCount; i++){
        View image = root.getChildAt(i);
        if (image instanceof ImageButton) {
            ((ImageButton)image).setOnClickListener(imageOnClickListener);
        }
    }
