MODE_IN_CALL、MODE_IN_COMMUNICATION MODE_CALL_SCREENING有什么区别?
What is the differences between MODE_IN_CALL, MODE_IN_COMMUNICATION, MODE_CALL_SCREENING?
问:
这就是文件所说的,但我不能完全理解。
/* modes for setMode/getMode/setRoute/getRoute */
/**
* Audio harware modes.
*/
/**
* Invalid audio mode.
*/
public static final int MODE_INVALID = AudioSystem.MODE_INVALID;
/**
* Current audio mode. Used to apply audio routing to current mode.
*/
public static final int MODE_CURRENT = AudioSystem.MODE_CURRENT;
/**
* Normal audio mode: not ringing and no call established.
*/
public static final int MODE_NORMAL = AudioSystem.MODE_NORMAL;
/**
* Ringing audio mode. An incoming is being signaled.
*/
public static final int MODE_RINGTONE = AudioSystem.MODE_RINGTONE;
/**
* In call audio mode. A telephony call is established.
*/
public static final int MODE_IN_CALL = AudioSystem.MODE_IN_CALL;
/**
* In communication audio mode. An audio/video chat or VoIP call is established.
*/
public static final int MODE_IN_COMMUNICATION = AudioSystem.MODE_IN_COMMUNICATION;
/**
* Call screening in progress. Call is connected and audio is accessible to call
* screening applications but other audio use cases are still possible.
*/
public static final int MODE_CALL_SCREENING = AudioSystem.MODE_CALL_SCREENING;
你能举例说明一下吗?
目前,我在 WebView 上使用视频聊天服务,我得到,它使用媒体音量,它应该使用“通话”音量。我怎样才能强迫它?MODE_CALL_SCREENING

MODE_IN_CALL
您正在通过纯音频通话(普通电话)与某人交谈
MODE_IN_COMMUNICATION,您正在与朋友进行视频和音频聊天或在VoIP上呼叫他们
MODE_CALL_SCREENING
您的电话响了,并且您在接听电话之前正在检查号码

mode 参数在 AudioSystem 类中定义,用于设置手机的状态
MODE_IN_CALL:来电模式。电话呼叫已建立。
Constant Value:
2 (0x00000002)
public static final int MODE_IN_CALL
private void setAudioNormal() {
AudioManager audioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_NORMAL);
audioManager.setSpeakerphoneOn(false);
}
}
另一个例子
import android.media.AudioManager;
public void startOutgoingRinger(OutgoingRinger.Type type) {
AudioManager audioManager = ServiceUtil.getAudioManager(context);
audioManager.setMicrophoneMute(false);
if (type == OutgoingRinger.Type.SONAR) {
audioManager.setSpeakerphoneOn(false);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
} else {
audioManager.setMode(AudioManager.MODE_IN_CALL);
}
outgoingRinger.start(type);
}
MODE_IN_COMMUNICATION:在通信音频模式下。建立音频/视频聊天或 VoIP 通信。
Constant Value:
3 (0x00000003)
public static final int MODE_IN_COMMUNICATION
private void chooseVoiceMode() {
AudioManager audioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
if(mAudioConfiguration.aec) {
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
audioManager.setSpeakerphoneOn(true);
} else {
audioManager.setMode(AudioManager.MODE_NORMAL);
audioManager.setSpeakerphoneOn(false);
}
}
MODE_CALL_SCREENING:正在进行呼叫筛选。已接通呼叫,但音频未使用。 呼叫筛选:这是识别来电者、提供有关来电者的信息以及确定如何最好地响应该呼叫的过程。
Constant Value:
4 (0x00000004)
public static final int MODE_CALL_SCREENING
public int getMode() {
final IAudioService service = getService();
try {
int mode = service.getMode();
int sdk;
try {
sdk = getContext().getApplicationInfo().targetSdkVersion;
} catch (NullPointerException e) {
// some tests don't have a Context
sdk = Build.VERSION.SDK_INT;
}
if (mode == MODE_CALL_SCREENING && sdk <= Build.VERSION_CODES.Q) {
mode = MODE_IN_CALL;
}
return mode;
} catch (RemoteException e) {
throw e.rethrowFromSystemServer();
}
}

您能否解释何时使用哪个以及为什么使用?使用一个比另一个有什么好处?

我读了你的答案,它很有用,但你没有解释为什么使用一个而不是另一个。这些标志的效果/好处是什么?例如,我在应用程序中将MODE_IN_COMMUNICATION替换为MODE_IN_CALL,会有什么变化?用户将受到什么影响?
