如何使用sqlite在android中绑定微调器？

Question

我有一个包含

的表格

------------------------
id    |Name
------------------------
16001 |ABC
16002 |QWE
16003 |RTY
16004 |JHG

并将其绑定到微调器;带有名称的微调器项和带有id的spinneritemposition。

我到目前为止尝试了这个：

    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, lables);
    // Drop down layout style - list view with radio button 
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_ite‌​m);
    List<String> lables = dataSource.getAllmothers();

    public List<String> getAllmothers()
    {
       List<String> labels = new ArrayList<String>();
       database = dbHelper.getReadableDatabase(); // Select All Query
       String selectQuery = "SELECT id,name FROM "+dbHelper.TABLE_REGISTRATION;
       Cursor cursor = database.rawQuery(selectQuery, null); // looping through all rows and adding to list 
      if (cursor.moveToFirst()) { 
        do
         { 
          labels.add(Integer.toString(cursor.getInt(0)));
          labels.add(cursor.getString(1)); 
        } while (cursor.moveToNext()); 
      } // closing connection
      cursor.close(); 
      database.close(); // returning lables

   return labels; 
 }

像这样创建数组适配器 ArrayAdapter ad = new ArrayAdapter（cureentclass，dropdownstyle，values）

值是您通过数据库值变量获取的值，并将Array Adapter绑定到微调器。
