Question

我谨申请从林顿·曼纳格名单上删除所有环状地名。我已实施我的申请,将装置上的所有环绕道带进如下:

   Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
    startActivity(intent);

申请一开始,我就获得辩证。在这一方言中,我把环状 to放在与无线电纽州进行的清单中。我谨将清单中的所有项目印成我的申请。

如何从缺电线管理人名单中打印所有物品?

Answer 1

您是否尝试了getCursor() 方法?

根据:

public Cursor getCursor ()

Returns a Cursor of all the ringtones available. The returned cursor will be the same cursor returned each time this method is called, so do not close() the cursor. The cursor can be deactivate() safely. If RingtoneManager(Activity) was not used, the caller should manage the returned cursor through its activity s life cycle to prevent leaking the cursor.

Answer 2

你可以做些什么。

    RingtoneManager ringtoneManager = new RingtoneManager(yourActivity);
    ringtoneManager.setType(RingtoneManager.TYPE_RINGTONE);
    Cursor cursor = ringtoneManager.getCursor();
    while (cursor.moveToNext()) {
     System.out.println(cursor.getString(RingtoneManager.TITLE_COLUMN_INDEX));
     System.out.println(cursor.getString(RingtoneManager.URI_COLUMN_INDEX));
    }
