我通過擴展AutoCompleteTextView（使用名爲setCursorAdapter的專用函數）來創建自定義視圖。我提供了一個SimpleCursorAdapter並添加了一個FilterQueryProvider。我使用這個數字列表，我需要能夠搜索匹配數字中的任何地方。使用AutoCompleteTextView將文本自定義光標
public void setCursorAdapter(final Uri uri, final String key) {
Cursor c = getContext().getContentResolver().query(uri,
new String[] { "_id", key }, null, null, key);
SimpleCursorAdapter adapter = new SimpleCursorAdapter(getContext(),
android.R.layout.simple_dropdown_item_1line, c,
new String[] { key }, new int[] { android.R.id.text1 });
this.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
((SimpleCursorAdapter) getAdapter()).getFilterQueryProvider()
.runQuery(s);
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
}
});
adapter.setFilterQueryProvider(new FilterQueryProvider() {
@Override
public Cursor runQuery(CharSequence constraint) {
Cursor c = getContext().getContentResolver().query(uri,
new String[] { "_id", key },
key + " LIKE '%" + constraint + "%'", null, key);
return c;
}
});
setAdapter(adapter);
}
一切都很完美，直到我從下拉列表中選擇數值。我在EditText窗口中收到的值：android.content.ContentResolver $ CursorWrapperInner @ ...
如何避免這種情況並使我的（數字）文本正確顯示。
