For this you have to manipulate thread. Check here----> http://www.tutorialspoint.com/java/java_thread_control.htm http://stackoverflow.com/questions/10961714/how-to-properly-stop-the-thread-in-java — Chaudhary Amar, Jan 04 '16 at 05:45

I achieving my functionality by using https://github.com/Trinea/android-auto-scroll-view-pager

I used following custom viewpager

<cn.trinea.android.view.autoscrollviewpager.AutoScrollViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="wrap_content" />

and set interval for specific time for auto slide

setInterval(long)

Then used : startAutoScroll() method for auto slide

and : topAutoScroll() for stop animation on touch , like following ,

     layout.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {

                switch(event.getAction())
                {
                    case MotionEvent.ACTION_DOWN:
                        Log.w("touched","down");
                        stopScroll();
                        return true;
                        //break;

                    case MotionEvent.ACTION_UP:
                        Log.w("touched","up");
                        startScroll();
                        return true;
                        //break;
                }

                return false;
            }
        });

and use following gradle :

compile ('cn.trinea.android.view.autoscrollviewpager:android-auto-scroll-view-pager:1.1.2') 
{
   exclude module: 'support-v4'
}

You can identify touch event of viewpager and on the basis of you can stop and start slider. Like below you will get touch event and then you can maintain your thread work.

viewPager.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
    // put your code here to stop and start slide, means put your thread code here..
                    return false;
                }
            });
