android - 在 AutoCompleteTextView 中进行选择时崩溃

Question

显然，this和 this与我遇到的问题相同，尽管我的 Textview 是 AutoCompleteTextView。我正在从我的联系人列表中选择。每当我进行选择时，我都会收到以下错误:

java.lang.IllegalArgumentException: Invalid offset: -1. Valid range is [0, 23]
    at android.text.method.WordIterator.checkOffsetIsValid(WordIterator.java:384)
    at android.text.method.WordIterator.preceding(WordIterator.java:72)

这似乎是由于在允许范围之外选择了光标。上面链接中给出的解决方法似乎没有帮助。这是崩溃发生的地方:

public class AutoCompleteContactTextView extends AppCompatAutoCompleteTextView implements CustomAdapter.AsyncLoad {

private void init(Context context, AttributeSet attrs, boolean programmatic) {
    this.context = context;
    this.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if (AutoCompleteContactTextView.this.getAdapter() != null && !s.toString().equalsIgnoreCase("")) {
                ((CustomAdapter) AutoCompleteContactTextView.this.getAdapter()).getFilter().filter(s);
                ((CustomAdapter) AutoCompleteContactTextView.this.getAdapter()).notifyDataSetChanged();
                ArrayList<People> arrPeople = ((CustomAdapter) AutoCompleteContactTextView.this.getAdapter()).dataList;
                Log.d("We're Here", "We're here in onTextChanged");
                //searchText = s;
            }
            if (!somethingIsSelected) {
                selected = null;
            }
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
    this.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            selected = (People) getAdapter().getItem(position);
            GlobalVars.selectedPerson = selected;
            somethingIsSelected = true;
            String name = selected.getName().toString();
            setText(null);
            setText(selected.getName(), TextView.BufferType.SPANNABLE); //<--crash happens here. 
            Log.d("Something Selected", String.valueOf(somethingIsSelected));

        }
    });
}

我在模拟器 Nexus 5 API 27 上运行它。这也发生在运行 API 27 的 Pixel XL 模拟器上。这不会在真实设备上崩溃(我的三星 Galaxy S7 Edge，运行 API 24)。

显然，所选项目的值被设置为类，而不是字符串。我更新了 AutoCompleteTextView 的过滤器，然后应用程序可以获得字符串的值。

    this.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            selected = (People) getAdapter().getItem(position);
            GlobalVars.selectedPerson = selected;
            somethingIsSelected = true;
            Log.d("Something Selected", String.valueOf(somethingIsSelected));

        }
    });



    @Override
    public Filter getFilter() {
        filter = new Filter() {
            @Override
            public String convertResultToString(Object resultValue) {
                String str = ((People)(resultValue)).getName();
                return str;
            }
        .....
     }   

AutoCompleteTextView 的 get Item 返回一个 Object，因此针对此问题的另一个修复也可能发生变化:

    @Override
    public Object getItem(int position) {
        return toDisplayList.get(position);
    }

到

    @Override
    public String getItem(int position) {
        return toDisplayList.get(position).getName();
    }

我正在使用这个类的一个版本:
