Android中DrawerLayout+ViewPager滑动冲突的解决方法

@Overridepublic boolean onTouchEvent(MotionEvent ev) {  mLeftDragger.processTouchEvent(ev);   mRightDragger.processTouchEvent(ev);   final int action = ev.getAction(); boolean wantTouchEvents = true;   switch (action & MotionEventCompat.ACTION_MASK) {     case MotionEvent.ACTION_DOWN: {       final float x = ev.getX();       final float y = ev.getY();       mInitialMotionX = x;       mInitialMotionY = y;       mDisallowInterceptRequested = false;       mChildrenCanceledTouch = false;       break;     }     case MotionEvent.ACTION_UP: {       final float x = ev.getX();       final float y = ev.getY();       boolean peekingOnly = true;      final View touchedView = mLeftDragger.findTopChildUnder((int) x, (int) y);       if (touchedView != null && isContentView(touchedView)) {         final float dx = x - mInitialMotionX;         final float dy = y - mInitialMotionY;         final int slop = mLeftDragger.getTouchSlop();         if (dx * dx + dy * dy < slop * slop) {           // Taps close a dimmed open drawer but only if it isn't locked open.           final View openDrawer = findOpenDrawer();           if (openDrawer != null) {             peekingOnly = getDrawerLockMode(openDrawer) == LOCK_MODE_LOCKED_OPEN;           }         }        }       closeDrawers(peekingOnly);       mDisallowInterceptRequested = false;       break;     }     case MotionEvent.ACTION_CANCEL: {       closeDrawers(true);       mDisallowInterceptRequested = false;      mChildrenCanceledTouch = false; break;     }   }   return wantTouchEvents;}
