测量ScrollView的相关高度(监听滑动到顶端和底部)

private void init() {
		mScrollView = (ScrollView) findViewById(R.id.scrollview);
		mScrollView.setOnTouchListener(new TouchListenerImpl());
	}

	class TouchListenerImpl implements OnTouchListener {

		@Override
		public boolean onTouch(View v, MotionEvent event) {

			switch (event.getAction()) {
			case MotionEvent.ACTION_DOWN:

				break;

			case MotionEvent.ACTION_MOVE:
				// ScollView顶端已经滑出去的高度
				int scrollY = v.getScrollY();
				// ScollView的可见高度
				int height = v.getHeight();
				// ScollView所占的高度
				int measuredHeight = mScrollView.getChildAt(0)
						.getMeasuredHeight();
				if (scrollY == 0) {
					Log.d(TAG, "滑动到顶端");
					Log.d(TAG, scrollY+"");
					Log.d(TAG, measuredHeight+"");
				}
				if ((scrollY + height) == measuredHeight) {
					Log.d(TAG, scrollY+"");
					Log.d(TAG, height+"");
					Log.d(TAG, measuredHeight+"");
				}
				break;
			}
			return false;
		}
	}
