我有4个动态创建的Videoview。我只想为来自服务器的一个视频设置自定义音量,其余三个视频将静音。
我想为我在以下代码下尝试过的特定视频设置自定义音量
vid1.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
{
public void onPrepared(MediaPlayer mp)
{
//mp.setVolume(100f, 100f);
//mp.setLooping(true);
vid1.enableSound(20,mp); //here i will set music sound dynamically
vid1.start();
playingvideo1 = true;
}
});
//startTimeForContent = dateFormatForContent.format(new Date());
vid1.setOnErrorListener(mOnErrorListener2);
playBackfunction1();
}
public void enableSound(int sound, MediaPlayer mp){
Float f = Float.valueOf(sound);
Log.e("checkingsounds","&&&&& "+f);
mp.setVolume(f,f);
mp.setLooping(true);
AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, sound, AudioManager.FLAG_PLAY_SOUND);
}
当我将音量设为0时,它正在工作...但是当更改10、20、30时,视频将播放完整的声音。...
我已经在下面进行研究了
sound volume not working on Android
答案 0 :(得分:0)
研究了几个小时后,我找到了解决方法
您需要将音量0设置为15
GGGGG
vid1.setOnPreparedListener(new MediaPlayer.OnPreparedListener()
{
public void onPrepared(MediaPlayer mp)
{
//mp.setVolume(100f, 100f);
//mp.setLooping(true);
vid1.enableSound(10,mp); //set Volume 0 to 15.
vid1.start();
playingvideo1 = true;
}
});
//startTimeForContent = dateFormatForContent.format(new Date());
vid1.setOnErrorListener(mOnErrorListener2);
playBackfunction1();
}
