android: one click listener on many imageviews in layout

I have the following scenario:

enter image description here

In a layout, I have imageviews aligned horizontally and vertically as shown in image.

First, which layout should be used for this purpose? RelativeLayout or FrameLayout? ListView inside the layout?

Also, instead of writing setOnClickListener for every imageview, how can I write just one click listener to get the clicked imageview?

Use 'GridView' in the layout and use 'setOnItemClickListener' to handle click events,

You can find more details in below link GridView.

GridView can achieve the effect. I think you can look at this Grid View.

A GridView is perfect for this. For more information on GridView, look here.

As for your onClickListener question: there is no easy way to do this, but what you can do is something like this:

  1. Have an array containing every ImageView id like so:

    public static final int[] IMAGE_VIEWS = {R.id.imageView1, R.id.imageView2, R.id.imageView3 /*etc*/}; //Make sure to list from the first imageview to the last image view in correct order

  2. Define an onClickListener

    private View.OnClickListener imageViewListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        for (int i = 0; i < IMAGE_VIEWS.length; i++) {
            if (v.getId() == IMAGE_VIEWS[i]) {
                doSomethingWithImageViewClick(i); //if ImageView 4 was clicked, variable 'i' will be 3 (because arrays start at index = 0).
            }
        }
    }
}

  3. Set the onClickListeners for all your imageViews:

    final ImageView view1 = (ImageView) view.findViewById(R.id.imageView1);
view1.setOnClickListener(imageViewListener);
//etc
