我想改变铃声音量

发布于 2024-11-06 03:08:40 字数 190 浏览 0 评论 0原文

我使用此代码来调节音量，但它不起作用

int volume=23;
audio.setStreamVolume(AudioManager.STREAM_RING,volume, AudioManager.FLAG_PLAY_SOUND|AudioManager.FLAG_ALLOW_RINGER_MODES);}

原文

i used this code to adjust volume but it didn't work

int volume=23;
audio.setStreamVolume(AudioManager.STREAM_RING,volume, AudioManager.FLAG_PLAY_SOUND|AudioManager.FLAG_ALLOW_RINGER_MODES);}

您不应该只是将音量设置为 23，而应该首先调用 getStreamMaxVolume(StreamType) 以获取 StreamType 可能的最大音量，在本例中是铃声的音量。

例如，要将铃声音量设置为最大，您可以这样做！

audioManager.setStreamVolume(AudioManager.STREAM_RING, audioManager.getStreamMaxVolume(AudioManager.STREAM_RING), FLAG_ALLOW_RINGER_MODES|FLAG_PLAY_SOUND);

更新

    int streamMaxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
    Toast.makeText(this, Integer.toString(streamMaxVolume), Toast.LENGTH_LONG).show(); //I got 7
    audioManager.setStreamVolume(AudioManager.STREAM_RING, streamMaxVolume, AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);

好。现在我在家我可以尝试代码。正如您所看到的，streamMaxVolume 给我一个整数 7。如果您尝试将其设置为 23，那就太多了。因此，在我的例子中，您可以在 setStreamVolume 中使用的可能值是

0, 1, 2, 3, 4, 5, 6, 7
最低<----->最高

//set to lowest ->
audioManager.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);

//set to loudest ->
audioManager.setStreamVolume(AudioManager.STREAM_RING, 7, AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);

you should not just set the volume to 23 instead you should first make a call to getStreamMaxVolume(StreamType) to get the max volume possible for the StreamType which in this case is the ringer's volume.

for example, to set the ringer's volume to max you do this!

audioManager.setStreamVolume(AudioManager.STREAM_RING, audioManager.getStreamMaxVolume(AudioManager.STREAM_RING), FLAG_ALLOW_RINGER_MODES|FLAG_PLAY_SOUND);

UPDATES

    int streamMaxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
    Toast.makeText(this, Integer.toString(streamMaxVolume), Toast.LENGTH_LONG).show(); //I got 7
    audioManager.setStreamVolume(AudioManager.STREAM_RING, streamMaxVolume, AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);

ok. now that i am at home i can try out codes. here as you can see, streamMaxVolume gives me a integer of 7. if you try to set it to 23 its way too much. so the possible values you can use in setStreamVolume in my case is

0, 1, 2, 3, 4, 5, 6, 7
Lowest <-----> Highest

//set to lowest ->
audioManager.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);

//set to loudest ->
audioManager.setStreamVolume(AudioManager.STREAM_RING, 7, AudioManager.FLAG_ALLOW_RINGER_MODES|AudioManager.FLAG_PLAY_SOUND);
