我陷入一个问题，我有一个MultiAutoCompleteTextView，如下图所示：
在这种情况下，我从MultiAutoCompleteTextView的建议中选择城市名称，然后在ListView中添加该项目（如下所示）。我想防止输入其他条目而不是ADAPTER值。
我用这种方式绑定代码，而onClick的Button用逗号分隔值：
private void initComp() { // GET DATA FROM DATABASE
multiSelectCities = (MultiAutoCompleteTextView) findViewById(R.id.activity_multiselect_city);
btnGetCity = (Button) findViewById(R.id.activity_btn_slect_city);
listCity = (ListView) findViewById(R.id.activity_get_city_list);
btnGetCity.setOnClickListener(this);
dbHelper = new DatabaseHelper(getApplicationContext());
dbHelper.open();
setName();
// dbHelper.close();
}
public void setName() { // FOR SET THE NAME IN MULTISELECT TEXTVIEW
final Cursor localcursor = dbHelper.getArea();
if ((localcursor != null) && (localcursor.getCount() > 0)) {
arrayOfString = new ArrayList < String > ();
localcursor.moveToFirst();
do {
arrayOfString.add(localcursor.getString(localcursor.getColumnIndex(DatabaseHelper.CITY_NAME)) + "-" + localcursor.getString(localcursor.getColumnIndex(DatabaseHelper.CITY_COUNTRY)));
} while (localcursor.moveToNext());
this.multiSelectCities.setThreshold(3);
adapter = new CityDataWithMultitextAdapter(this, arrayOfString);
multiSelectCities.setAdapter(adapter);
multiSelectCities.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
/* localcursor.close(); */
}
@Override
public void onClick(View v) { //SEARCH BUTTON CLICK AND STORE THE DATA INTO LISTVIEW
if (!Utils.isEmpty(multiSelectCities)) {
arrayList = multiSelectCities.getText().toString().substring(0, multiSelectCities.length() - 1).split(",");
for (int i = 0; i < arrayList.length; i++) {
selectedItems.add(arrayList[i].trim());
}
} else {
Utils.displayToast(this, "Please Enter City/Cities");
}
CityListAdapter adapter = new CityListAdapter(this, selectedItems);
listCity.setAdapter(adapter);
multiSelectCities.setText("");
listCity.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView <? > parent, View view, int position, long id) {
Intent i = new Intent(CityListDataActivity.this, CityListDetail.class);
i.putExtra("CITY_NAME", selectedItems.get(position).toString());
startActivity(i);
}
});
}
}
我正在考虑通过SELECT查询与数据库一起检查输入的值，但是我有75000多个记录，因此这很难解决。
有帮助吗？它将不胜感激。
最佳答案
一种方法是消除使用以下命令在AutoCompleteTextView内部编写的可能性：
<AutoCompleteTextView
android:editable="false"
android:inputType="none"
..../>
以及onTouch呼叫显示适配器，它将显示城市列表。
private AutoCompleteTextView mAutoText;
mAutoText.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
mAutoText.showDropDown();
mAutoText.setListSelection(mPos);
return false;
}
});
mAutoText.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
mAdapter.setSelection(position);
mPos = position;
}
});
