ViewPager intercepts all x-axis onTouch events. How to disable?

Solution 1:

You are right, I believe every scrolling container intercepts touch events, but you can prevent it. You can put a touch listener on your layout:

public boolean onTouch(View v, MotionEvent event) {
    switch (event.getAction()) {
    case MotionEvent.ACTION_MOVE: 
        pager.requestDisallowInterceptTouchEvent(true);
        break;
    case MotionEvent.ACTION_UP:
    case MotionEvent.ACTION_CANCEL:
        pager.requestDisallowInterceptTouchEvent(false);
        break;
    }
}

Solution 2:

Similar situation (but not using a ViewPager), putting this in the view that needed the touch event worked for me. Add checks for MotionEvents other than ACTION_MOVE if applicable to your use case.

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_MOVE) {
        this.getParent().requestDisallowInterceptTouchEvent(true);
        return true;
    } else {
        return super.onTouchEvent(event);
    }
}

Solution 3:

neutrino was right!

getParent().requestDisallowInterceptTouchEvent(true);

once the viewpager access the touchEvent Intercept,the child view in it can got the event. enter image description here

I use a FrameLayout in viewpager to got the DrawerLayout Effect(I need it not match the height of screen,so I can't use drawerlayout or navigation drawer).
It really helps!
