虽然我来不及回答。它可能仍然有助于所有人都在搜索同样的问题。
在开始录音机之前添加以下两行代码.. 它会使手机静音...
//mute phone
AudioManager audioManager = (AudioManager) context.getSystemService(AUDIO_SERVICE);
audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
mediaRecorder.start();
启动录音机后等待一到两秒钟并取消静音,你可以使用以下可运行的...
new Thread(new UnmuterThread()).start();
//timer thread to un-mute phone after 1 sec
//This is runnable inner class inside your activity/service
class UnmuterThread implements Runnable{
@Override
public void run() {
synchronized (this){
try {
wait(1000);
} catch (InterruptedException e) {
} finally {
//unmute the phone
AudioManager audioManager1 = (AudioManager) context.getSystemService(AUDIO_SERVICE);
audioManager1.setRingerMode(AudioManager.RINGER_MODE_NORMAL); }
}
}
}
