您应该在滚动中运行代码。像这样发帖:

scroll.post(new Runnable() {            
    @Override
    public void run() {
           scroll.fullScroll(View.FOCUS_DOWN);              
    }
});

scroll.fullScroll(View.FOCUS_DOWN)也应该工作。

把这个放在卷轴里。Post(可运行)

芬兰湾的科特林代码

scrollView.post {
   scrollView.fullScroll(View.FOCUS_DOWN)
}

我尝试成功了。

scrollView.postDelayed(new Runnable() {
    @Override
    public void run() {
        scrollView.smoothScrollTo(0, scrollView.getHeight());
    }
}, 1000);

这并不是问题的确切答案，但我需要在EditText获得焦点后立即向下滚动。然而，公认的答案将使ET也失去焦点(我假设ScrollView)。

我的解决方案如下:

emailEt.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus){
            Toast.makeText(getActivity(), "got the focus", Toast.LENGTH_LONG).show();
            scrollView.postDelayed(new Runnable() {
                @Override
                public void run() {
                    scrollView.fullScroll(ScrollView.FOCUS_DOWN);
                }
            }, 200);
        }else {
            Toast.makeText(getActivity(), "lost the focus", Toast.LENGTH_LONG).show();
        }
    }
});

这招立竿见影。没有延迟。

// wait for the scroll view to be laid out
scrollView.post(new Runnable() {
  public void run() {
    // then wait for the child of the scroll view (normally a LinearLayout) to be laid out
    scrollView.getChildAt(0).post(new Runnable() {
      public void run() {
        // finally scroll without animation
        scrollView.scrollTo(0, scrollView.getBottom());
      }
    }
  }
}

当视图尚未加载时，您不能滚动。你可以“稍后”用上面的post或sleep call来做这件事，但这不是很优雅。

最好计划滚动并在下一个onLayout()中执行。示例代码如下:
