推荐答案

我能够使用InCallService解决此问题，我正在使用它来将应用程序开发为默认拨号程序.您所要做的就是获取扩展InCallService的CallService类的实例.由于在Android 10上您不能直接使用setSpeakerphoneOn()，因此在Android 9上效果很好.InCallService具有setAudioRoute()方法，可用于路由音频.到目前为止，我已经在Android 10和9上测试了以下代码.还测试了在通话过程中扬声器和听筒之间交替显示的Wouter Vanhauwaert问题，该方法也很好用.我的代码如下.

I was able to resolve the issue using InCallService which I am using to develop an app as Default Dialer. All you have to do is get the instance of the CallService class which extends InCallService. Since on Android 10 you cannot directly use setSpeakerphoneOn(), which works great on Android 9. InCallService have a method setAudioRoute() which you can use to route your audio. So far I have tested the below code on Android 10 and 9. Also tested Wouter Vanhauwaert issue of alternating between speaker and earpiece during a call which also works fine. My Code is as below.

CallService.java

public class CallService extends InCallService {

  private static CallService sInstance;
  ……

  @Override
  public void onCreate() {
    super.onCreate();
    sInstance = this;
  }
  public static CallService getInstance(){
    return sInstance;
  }
}

AnotherActivity.java

public void toggleSpeaker() {
 AudioManager am = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
 boolean isSpeakerOn = audioManager.isSpeakerphoneOn();
 int earpiece = CallAudioState.ROUTE_WIRED_OR_EARPIECE;
 int speaker = CallAudioState.ROUTE_SPEAKER;

 if (android.os.Build.VERSION.SDK_INT > android.os.Build.VERSION_CODES.P){
 CallService.getInstance().setAudioRoute(isSpeakerOn ? earpiece : speaker);
 } else {
   am.setSpeakerphoneOn(!isSpeakerOn);
 }
}
