How to shut off the sound MediaRecorder plays when the state changes
Need to shut off the sound MediaRecorder plays when the state changes
但它们都不起作用.
谁知道如何实现这一目标？
解决方法
虽然我来不及回答它.它仍然可以帮助所有人都在谷歌搜索同样的问题.
在开始媒体记录器之前添加以下两行代码..
它会静音手机声音..
//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); }
}
}
}
