Click or select the ViewPagerIndicator event in Android

May be duplicated:

I am using ViewPagerIndicator in my Android application to scroll through the dynamic view number and its performance is excellent.

What do you need? . When the user clicks on one of the slides, the corresponding view will open. But I can not override the touch event on Pager .

Operation code:

public class MainActivity extends BaseSampleActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAdapter = new TestFragmentAdapter(getSupportFragmentManager());

        mPager = (ViewPager)findViewById(R.id.pager);
        mPager.setAdapter(mAdapter);

        mPager.setOnTouchListener(new View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                // TODO Auto-generated method stub
                System.out.print(event.getAction());//not working

                return false;
            }
        });

        mIndicator = (CirclePageIndicator)findViewById(R.id.indicator);
        mIndicator.setViewPager(mPager);
    }
}

I searched a lot, but did not find the right solution. But they did not receive a correct and short answer.

        }   

        @Override
        public boolean onInterceptTouchEvent(MotionEvent event) {

            return super.onInterceptTouchEvent(event);
        }

        @Override
        public boolean onTouchEvent(MotionEvent event){
            return super.onTountEvent(event);
        }

    }

click GestureDetector. MotionEvent tapGestureDetector.

tapGestureDetector = new GestureDetector(this, new TapGestureListener());

    viewPager.setOnTouchListener(new OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                tapGestureDetector.onTouchEvent(event);
                return false;
            }
    });

, :

tapGestureDetector = new GestureDetectorCompat(this, new TapGestureListener());

GestureListener:

class TapGestureListener extends GestureDetector.SimpleOnGestureListener{

     @Override
     public boolean onSingleTapConfirmed(MotionEvent e) {
       // Your Code here
     }
}
