Question

I have spinner which I populate from SQLite database. But I want to populate it from string-array:

<string-array name="category">
    <item name="accommodation">Accommodation</item>
    <item name="automobile">Automobile</item>
    <item name="credit cards">Credit Cards</item>
    <item name="donations">Donations</item>
    <item name="entertainment">Entertainment</item>
    <item name="food">Food</item>
</string-array>

where name I take from SQLite table.
I have method which retrieve name from database:

public Cursor getAllCategory() {
    mDB = dbHelper.getReadableDatabase();
    return mDB.query(CATEGORY_TABLE_NAME, null, null, null, null, null,null);
}

And in my program I use these names:

// spinner
        catSpinner = (Spinner) view.findViewById(R.id.category_spinner);
        cursor = adapter.getAllCategory();
        String[] from = new String[] { DataAdapter.CATEGORY_COL_NAME };
        int[] to = new int[] { android.R.id.text1 };
        SimpleCursorAdapter catAdapter = new SimpleCursorAdapter(
                getActivity(),
                android.R.layout.simple_spinner_dropdown_item, cursor,
                from, to, 0);
        catAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        catSpinner.setAdapter(catAdapter);

But I want use names from database, but value that ​​responding to these names(string.xml) use from string-array

How I can do this? I want to do this to avoid changing database when I change localization.

Try this.For getting data into the spinner you have to use SimpleCursorAdapter which is given below.

  // This is your method of database class which returns cursor
 Public Cursor getAllNames(){
   return mDb.query(table_name, new String[]{KEY_ROWID, KEY_TITLE}, null, null, null, null, null );
}

And use this method in spinner to get items(i.e. Name).

 Cursor c = mDbHelper.getAllNames();
 startManagingCursor(c);

  String[] from = new String[]{your_name};
// create an array of the name which you want to bind our data to
  int[] to = new int[]{android.R.id.text1};

  // This is your simple cursor adapter
   SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_spinner_item, c, from, to );
   adapter.setDropDownViewResource( android.R.layout.simple_spinner_dropdown_item );

   Spinner s = (Spinner) findViewById( R.id.unique_id ); // This is your spinner
   s.setAdapter(adapter); // Set it to the adapter

Hope this helps. 🙂
