            }
        }

One easy way is to intercept all touch events. By default, ViewGroup#onInterceptTouchEvent returns false.

You may create a custom layout:

public class ClickableFrameLayout extends FrameLayout {
    private OnClickListener mOnClickListener;

    @Override
    public void setOnClickListener(OnClickListener l) {
        super.setOnClickListener(l);
        mOnClickListener = l;
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return mOnClickListener != null;
    }


    // Standard constructors — just pass everything
    public ClickableFrameLayout(final Context context) {
        super(context);
    }

    public ClickableFrameLayout(final Context context, final AttributeSet attrs) {
        super(context, attrs);
    }

    public ClickableFrameLayout(final Context context, final AttributeSet attrs, final int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public ClickableFrameLayout(final Context context, final AttributeSet attrs, final int defStyleAttr, final int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }
}
