Получить список всех имен в поставщике контента

Question

Я использую поставщик контента «Calls.CONTENT_URI». Я уже получил имена столбцов, но теперь я хотел бы получить, скажем, ВСЕ имена из имени столбца «имя» в этом контент-провайдере.

У меня есть код ниже:

uri = Calls.CONTENT_URI; 

    String[] projection = {"name"}; 
    String selection = null; 
    String[] selectionArgs = null; 
    String sort = null; 


    resolver = getContentResolver(); 

    cursor = resolver.query(uri, projection, selection, selectionArgs, sort); 
    Log.i("TUTORIAL", "counts :"+cursor.getCount());  

    String s; 
    cursor.moveToFirst(); 

    for(int x=0; x<cursor.getCount(); x++){ 

     s = cursor.getString(x); 
     Log.i("TUTORIAL", ""+s); 

     //cursor.moveToNext(); 


    } 

Но это retrives только одно имя. Я хотел бы иметь список всех имен, сохраненных в телефоне, как:

Джон Питер Марк Сюзи . . X

Но теперь я получил только одно имя, как:

Петра. Надеюсь, я был достаточно ясен.

В чем проблема? Благодарим за помощь заранее.

Answer 1

Я думаю, что это поможет вам

 ArrayList<String> nameList = new ArrayList<String>(); 
    String[] projection = {"name"}; 
    String selection = null; 
    String[] selectionArgs = null; 
    String sort = null; 
    resolver = getContentResolver(); 
    cursor = resolver.query(uri, projection, selection, selectionArgs, sort); 
    Log.i("TUTORIAL", "counts :"+cursor.getCount());  
    String s; 
    if(cursor.moveToFirst()) { 
     do { 
      nameList.add(cursor.getString(0)); 
      //your code 
      //s = cursor.getString(x); 
      Log.i("TUTORIAL", ""+cursor.getString(0)); 
     }while(cursor.moveToNext()); 
    } 

Answer 2

вы можете попробовать это, он работает для меня:

public void readContacts() { 
     Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, 
       null, null, null); 
     if (cur.getCount() > 0) { 
      while (cur.moveToNext()) { 
       if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 

        // Get contact id (id) 
        String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 

        // Get contact name (displayName) 
        String displayName = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

       } 
      } 
     } 
     cur.close(); 
    } 

Answer 3

Это код.

public class MainActivity extends AppCompatActivity { 
SimpleCursorAdapter mAdapter; 
MatrixCursor mMatrixCursor; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    // The contacts from the contacts content provider is stored in this cursor 
    mMatrixCursor = new MatrixCursor(new String[] { "_id","name","photo","details"}); 

    // Adapter to set data in the listview 
    mAdapter = new SimpleCursorAdapter(getBaseContext(), 
      R.layout.lv_layout, 
      null, 
      new String[] { "name","photo","details"}, 
      new int[] { R.id.tv_name,R.id.iv_photo,R.id.tv_details}, 0); 

    // Getting reference to listview 
    ListView lstContacts = (ListView) findViewById(R.id.lst_contacts); 

    // Setting the adapter to listview 
    lstContacts.setAdapter(mAdapter); 

    // Creating an AsyncTask object to retrieve and load listview with contacts 
    ListViewContactsLoader listViewContactsLoader = new ListViewContactsLoader(); 

    // Starting the AsyncTask process to retrieve and load listview with contacts 
    listViewContactsLoader.execute(); 
} 

/** An AsyncTask class to retrieve and load listview with contacts */ 
private class ListViewContactsLoader extends AsyncTask<Void, Void, Cursor> { 

    @Override 
    protected Cursor doInBackground(Void... params) { 
     Uri contactsUri = ContactsContract.Contacts.CONTENT_URI; 

     // Querying the table ContactsContract.Contacts to retrieve all the contacts
