 @Override
 public boolean onTouch(View view, MotionEvent motionEvent) {
  switch (motionEvent.getAction()) {
   case MotionEvent.ACTION_DOWN:


    break;

    System.out.println("height=" + height);
    System.out.println("scrollViewMeasuredHeight="
      + scrollViewMeasuredHeight);
    if (scrollY == 0) {
     System.out.println("滑动到了顶端 view.getScrollY()=" + scrollY);
    } else if ((scrollY + height) >= scrollViewMeasuredHeight) {
     Message msg = new Message();
     msg.what = 0;
     mHandlerht.sendMessage(msg);
