How to disable swiping a ViewPager from its edges?

Question

I have an activity containing a Navigation Drawer and a AutoScrollViewPager. When I **swipe from the left edge of my phone's screen to open the Navigation Drawer, the AutoScrollViewPager's page changes instead of Navigation Drawer coming out. How can I disable the swiping of AutoScrollViewPager from its edges?

P.S. I tried adding margin to the AutoScrollViewPager but it looks ugly and does not work if the margin isn't large enough.

Use Edge Flags

Here is the Documentation

Try using below code:

final View pagerView = findViewById(R.id.Pager); 
pagerView.setOnTouchListener(new View.OnTouchListener() 
{         
    @Override
    public boolean onTouch(View v, MotionEvent event)
    {
       if (event.getAction() == MotionEvent.ACTION_DOWN && event.getEdgeFlags() == MotionEvent.EDGE_LEFT) {
            return true;   //disable swipe
        }
    }
 });

Thanks for the answer but It is not working for me. I have put a toast inside the IF block and found out that the control never goes inside the IF block. Also, a warning is being displayed that "it has setOnTouchListener called but it does not override performOnClick". Also, I would like to mention that the ViewPager is an AutoScrollViewPager and hope that it does not make a difference. @rafsanahmad007 – Aayush Taneja Nov 17 '17 at 17:24
i can't exactly tell why it is not working. but u should take a look at this:https://stackoverflow.com/questions/6645537/how-to-detect-the-swipe-left-or-right-in-android and https://stackoverflow.com/questions/12884250/motionevent-handling-in-scrollview-in-android?noredirect=1&lq=1 – rafsanahmad007 Nov 17 '17 at 18:44

Try using below code:

public class CustomViewPager extends ViewPager {

private boolean enabled;

public CustomViewPager(Context context, AttributeSet attrs) {
    super(context, attrs);
    this.enabled = true;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (this.enabled) {
        return true;
    }

    return false;
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    if (this.enabled) {
        if (event.getAction() == MotionEvent.ACTION_DOWN && event.getEdgeFlags() == MotionEvent.EDGE_LEFT) {
            return true;   //disable swipe
        }
    }

    return false;
}

public void setPagingEnabled(boolean enabled) {
    this.enabled = enabled;
} }
