我知道如何使用搜索栏控制音量:
audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
int maxVolume = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
int curVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
SeekBar volControl = (SeekBar)findViewById(R.id.volbar);
volControl.setMax(maxVolume);
volControl.setProgress(curVolume);
volControl.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar arg0) {
}
@Override
public void onStartTrackingTouch(SeekBar arg0) {
}
@Override
public void onProgressChanged(SeekBar arg0, int arg1, boolean arg2) {
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC, arg1, 0);
}
});
但是..我不知道如何在AsyncTask类中执行此操作,该类在播放声音时显示对话框(使用搜索栏)...任何想法或示例?
谢谢!
