[英]Scroll View doesn't scroll to top - Android

I am trying to scroll to the top of my ScrollView , and I am using the below and both types it works a little over 50% the other time sit just stays where it is 我正在尝试滚动到我的ScrollView的顶部,我正在使用下面的两种类型,它的工作时间超过50%,而另一次只是停留在它的位置

private void focusOnView(){
    new Handler().post(new Runnable() {
        @Override
        public void run() {
            sv.scrollTo(0, sv.getTop());
        }
    });
}

And the other way I am doing it 而我正在这样做的另一种方式

sv.post(new Runnable() {
        public void run() {
            Log.i(TAG, "TOP TOP");
            sv.scrollTo(0, sv.getTop());
        }
    });

THnaks for the help 求助于此

Use this 用这个

sv.post(new Runnable() {
        public void run() {
            Log.i(TAG, "TOP TOP");
            sv.scrollTo(0, 0);
        }
    });

Another approach: 另一种方法:

sv.post(new Runnable() {
    public void run() {
        sv.fullScroll(ScrollView.FOCUS_UP);
    }
});

If you want to scroll to bottom, using FOCUS_DOWN. 如果要使用FOCUS_DOWN滚动到底部。
