android TextView多行文本始终显示滚动条并自动定位到底部

效果:

java: 用handler循环调用这个方法即可

public static void scroll2Bottom(final ScrollView scroll, final View inner) {
		Handler handler = new Handler();
		handler.post(new Runnable() {

			@Override
			public void run() {
				// TODO Auto-generated method stub
				if (scroll == null || inner == null) {
					return;
				}
				// 内层高度超过外层
				int offset = inner.getMeasuredHeight()
						- scroll.getMeasuredHeight();
				if (offset < 0) {
					System.out.println("定位...");
					offset = 0;
				}
				scroll.scrollTo(0, offset);
			}
		});
