android调用手机铃声

得到默认闹铃铃声：

RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

调用文件选择，选择铃声文件：

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
					intent.setType("audio/*");
					Intent intent1=Intent.createChooser(intent, "选择铃声");
					startActivityForResult(intent1, 10);

@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data)
	{
		super.onActivityResult(requestCode, resultCode, data);

		// 返回铃声uri
		if (requestCode == 10)
		{
			if (resultCode == RESULT_OK)
			{
				// 将返回的uri转为path，方便后续利用
				Uri uri = data.getData();
				Cursor cursor = getContentResolver().query(uri, null, null,
						null, null);

				if(cursor != null)
					cursor.moveToFirst();
				else
				{
					ToastUtil.showToastShort(ReadyActivity.this, "请选择有效的音频文件");
					return;
				}
				String strRingPath = cursor.getString(1);
				cursor.close();
				
				Log.i("ck", "ringPath>" + strRingPath);
			}
		}
	}

播放铃声代码：（这是播放默认闹铃的代码）

MediaPlayer mp = new MediaPlayer();
mp.setDataSource(this, RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE));
mp.prepare();
mp.start();
