Masoud Dadashi的回答帮助我弄清楚了。
这是最终的样子。
viewPager.setonTouchListener(new onTouchListener() { private int CLICK_ACTION_THRESHOLD = 200; private float startX; private float startY; @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: startX = event.getX(); startY = event.getY(); break; case MotionEvent.ACTION_UP: float endX = event.getX(); float endY = event.getY(); if (isAClick(startX, endX, startY, endY)) { launchFullPhotoActivity(imageUrls);// WE HAVE A CLICK!! } break; } v.getParent().requestDisallowInterceptTouchEvent(true); //specific to my project return false; //specific to my project } private boolean isAClick(float startX, float endX, float startY, float endY) { float differenceX = Math.abs(startX - endX); float differenceY = Math.abs(startY - endY); return !(differenceX > CLICK_ACTION_THRESHOLD || differenceY > CLICK_ACTION_THRESHOLD); } }
