如何从铃声preference选择播放铃声

问题描述

我想打它是由一个铃声preference选择铃声。我怎样才能打吗？

下面是我的xml文件code

 ＆LT;铃声preference
    机器人：标题=选择报警
    机器人：关键=铃声
    机器人：汇总=这是总结
    ＆GT;＆LT; /铃声preference＆GT;
 

下面是我在做什么在Java

 共享preferences getAlarms = preferenceManager.getDefaultShared preferences（getBaseContext（））;
串报警= getAlarms.getString（铃声，默认铃声）;
 

当我使用吐司这样

  Toast.makeText（getApplicationContext（），报警器，Toast.LENGTH_LONG）.show（）;
 

然后，它显示了这种类型的路径

 内容：// /内部/音频/媒体/ 50
 

但我不知道怎么玩这个。

请帮助。

解决方案

 私人无效报警（）{
    共享preferences getAlarms = preferenceManager。
                                  getDefaultShared preferences（getBaseContext（））;
    串报警= getAlarms.getString（铃声，默认铃声）;
    开放的我们的uri = Uri.parse（报警）;
    playSound（这一点，URI）;

    //调用mMediaPlayer.stop（）;当你想要的声音停止
}


私人MediaPlayer的mMediaPlayer;
私人无效playSound（上下文的背景下，开放的警报）{
        mMediaPlayer =新的MediaPlayer（）;
        尝试 {
            mMediaPlayer.setDataSource（背景下，警报）;
            最后AudioManager audioManager =（AudioManager）上下文
                    .getSystemService（Context.AUDIO_SERVICE）;
            如果（audioManager.getStreamVolume（AudioManager.STREAM_ALARM）！= 0）{
                mMediaPlayer.setAudioStreamType（AudioManager.STREAM_ALARM）;
                mMediaPlayer prepare（）。
                mMediaPlayer.start（）;
            }
        }赶上（IOException异常E）{
            的System.out.println（OOPS）;
        }
    }
 

这这里应该是你想要的:)我希望它的工作原理

I am trying to play a ringtone which is selected from a RingtonePreference. How can I play it?

Here is my xml file code

<RingtonePreference
    android:title="Choose Alarm"
    android:key="ringtone"
    android:summary="this is summary"
    ></RingtonePreference>

Here is what I am doing in java

SharedPreferences getAlarms = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
String alarms = getAlarms.getString("ringtone", "default ringtone");

When I use toast like this

Toast.makeText(getApplicationContext(), alarms, Toast.LENGTH_LONG).show();

Then it shows this kind of path

content://media/internal/audio/media/50

But I do not know how to play this one.

Help Please.

解决方案

private void alarm(){
    SharedPreferences getAlarms = PreferenceManager.
                                  getDefaultSharedPreferences(getBaseContext());
    String alarms = getAlarms.getString("ringtone", "default ringtone");
    Uri uri = Uri.parse(alarms);
    playSound(this, uri);

    //call mMediaPlayer.stop(); when you want the sound to stop
}


private MediaPlayer mMediaPlayer;
private void playSound(Context context, Uri alert) {
        mMediaPlayer = new MediaPlayer();
        try {
            mMediaPlayer.setDataSource(context, alert);
            final AudioManager audioManager = (AudioManager) context
                    .getSystemService(Context.AUDIO_SERVICE);
            if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) {
                mMediaPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
                mMediaPlayer.prepare();
                mMediaPlayer.start();
            }
        } catch (IOException e) {
            System.out.println("OOPS");
        }
    }

This here should be what you want :) I hope it works
