推荐答案

当用户再次开始滚动列表，显示键盘，如果用户倒是最好的解决办法我能想出这一点，是隐藏键盘再次TextView中。这pretty很多作品大部分操作系统版本和设备，不像其他的解决方案，你可以看到，比如设置dropDownHeight的高度。

The best solution I could come up for this, is hiding the keyboard when the user starts scrolling the list and showing the keyboard again, if the user touches on the textview again. This pretty much works for most of the OS versions and devices, unlike other solutions you could see, such as setting the height of the dropDownHeight.

下面是一个示例code隐藏键盘，当用户开始滚动。基本上，你需要创建你AutoCompleteTextView的适配器，触摸监听器。

Below is a sample code to hide the keyboard, when the user starts scrolling. Basically, you need to create a touch listener in your AutoCompleteTextView's adapter.

public View getView(final int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    ViewHolder holder;
    if (convertView == null) {
        convertView = inflater.inflate(viewResourceId, parent, false);
        holder = new ViewHolder();
        init(convertView, holder);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    convertView.setOnTouchListener(new View.OnTouchListener() {

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

            if (event.getAction() == MotionEvent.ACTION_DOWN) {
                InputMethodManager imm = (InputMethodManager) getContext()
                        .getSystemService(
                                Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(
                        searchView.getWindowToken(), 0);
            }

            return false;
        }
    });

    setView(position, holder);
    return convertView;
}
