I'm having a problem using Android's AutoCompleteTextView .
AutoComplete is giving me duplicate data because I am searching both the name and the email. I would like it to present only one value, either by searching by the name of the contact or by searching for the email.
Basically, I have a list that stores a HashMap containing the name and email of each contact:
List<Map<String, String>> contact_list = new ArrayList<>();
To populate Hashmap , I use Cursor to help me fetch the information from the Database:
Cursor cursor = database.rawQuery(ContactTable.SELECT_ALL, null);
if(cursor.getCount() > 0){
while(cursor.moveToNext()){
Map<String, String> contact_info = new HashMap<>();
contact_info.put("name", cursor.getString(ContactTable.COLUMN_CONTACT_NAME_IDX));
contact_info.put("email", cursor.getString(ContactTable.COLUMN_CONTACT_EMAIL_IDX));
contact_list.add(contact_info);
}
}
After I add all instances of HashMap to my list, I add this list to a SimpleAdapter and then this adapter in my AutoCompleteTextView :
auto_adapter = new SimpleAdapter(
mContext,
contact_list,
android.R.layout.simple_list_item_2,
new String[]{"name", "email"},
new int[]{android.R.id.text1, android.R.id.text2});
auto_complete.setAdapter(auto_adapter);
The threshold has value "1" and has been declared in the layout file:
<AutoCompleteTextView
android:id="@+id/dialog_participant_name_auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:layout_marginRight="@dimen/activity_horizontal_margin"
android:inputType="textCapWords"
android:hint="@string/dialog_participant_auto_name"
android:textColorHint="@color/hint_text_color"
android:completionThreshold="1"
android:visibility="gone"/>
It works almost perfectly, but it doubles the value of the search. For example, if I save a contact named "Fulano" and email "[email protected]" and search for "F", AutoCompleteTextView returns me two items:
