我AutoCompleteTextView在这种模式中提出建议时遇到问题 [action actionFromContact]（这些是 2 个适配器）ex call michael（其中“call”来自 action 适配器，“michael”来自 actionFromContact 适配器这些以下代码首先将适配器设置AutoCompleteTextView为项目，当文本更改为调用它时，重置为从名称联系数据库，所以它就像调用 michael，
问题项目数组太大，所以我不能使用替换的东西，第二个替换删除第一个条目，当第二个条目即名称被选择时下拉菜单，因为它已被空格替换
private AutoCompleteTextView mEditText;
private TextWatcher mTextWatcher;
private ContactPickerAdapter contactPickerAdapter;
String item[] = { "Call", "Call back"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mEditText = (WithSomeOneAutoCompleteTextView) findViewById(R.id.editTextTest);
contactPickerAdapter = new ContactPickerAdapter(this,
android.R.layout.simple_dropdown_item_1line,
ContactQuery.getContacts(this, false));
mEditText.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_dropdown_item_1line, item));
mTextWatcher = new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
String t = s.toString().replace("call ",");
contactPickerAdapter.getFilter().filter(t);
if (s.toString().equalsIgnoreCase("call ")) {
Toast.makeText(MainActivity.this, "CALL",
Toast.LENGTH_SHORT).show();
mEditText.setAdapter(contactPickerAdapter);
}
if (s.toString().equalsIgnoreCase("Call back")) {
// t.replace("call back ", "");
// System.out.println("t is: " + t);
// contactPickerAdapter.getFilter().filter(t);
Toast.makeText(MainActivity.this, "Launch",
Toast.LENGTH_SHORT).show();
}
}
};
}
这是 ContactPickerAdapter
