Android-调用setText后未显示AutoCompleteTextView [英] Android - AutoCompleteTextView not showing after setText is called

问题描述

我在AutoCompleteTextView上遇到了一个奇怪的问题.

I'm having a weird issue with AutoCompleteTextView.

我有一个AutoCompleteTextView，在键入时显示城市的建议. 通过JSON从远程服务器检索城市列表.当我使用软键盘或软键盘上的Mic按钮时，建议可以正常工作. AutoCompleteTextView确实显示了建议的城市.

I have a AutoCompleteTextView that shows suggestions of cities when typing in it. The list of cities is retrieved from a remote server via JSON. When I use the soft keyboard or the Mic Button on the soft keyboard, the suggestions work fine. AutoCompleteTextView does show the suggested cities.

但是，当我尝试使用myAutoCompleteTextView.setText("Chi")设置文本时出现问题，自动完成不显示. 我也尝试过myAutoCompleteTextView.append("Chi")，但还是没有运气.

But, I have a problem when I try to set the text using myAutoCompleteTextView.setText("Chi") , the auto complete does not show.. I have also tried myAutoCompleteTextView.append("Chi") but still no luck..

适配器在那里，只是没有显示建议.

The adapter is there, its just that the suggestions don't show.

有什么提示吗?

谢谢.

推荐答案

是的，在AutocompleteTextview中存在一个错误，该错误显示使用setText("");方法的默认建议.

Yes you are right there is a bug in AutocompleteTextview to show default suggestion using setText(""); method.

但是您可以通过添加一些下面的代码行来实现.

But you can achieve this by adding some more lines of code as below.

autoText.postDelayed(new Runnable() {
            @Override
            public void run() {
                autoText.showDropDown();
            }
        },500);
        autoText.setText("chi");
        autoText.setSelection(autoText.getText().length());
