任何人都可以告诉我如何在android中使耳机静音(targetSdkVersion 26)。我试过这个:
audioManager.setSpeakerphoneOn(false);
但它只会使扬声器静音,而不是耳机。 我也试过这个:
audioManager.setMode(AudioManager.MODE_IN_COMMUNICATION);
audioManager.setStreamVolume(STREAM_VOICE_CALL, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
还有这个:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
am.requestAudioFocus(new AudioFocusRequest.Builder(AudioManager.AUDIOFOCUS_GAIN_TRANSIENT_EXCLUSIVE)
.setAudioAttributes(new AudioAttributes.Builder().setUsage(USAGE_VOICE_COMMUNICATION).build()).build());
am.adjustVolume(AudioManager.ADJUST_MUTE, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
}
具有相同的效果。
我使用webrtc,我的目标是静音/取消静音输出音频。非常感谢你。
以下是如何静音/取消静音:
private RTCSession currentSession;
private void setAudioEnabled(boolean isAudioEnabled) {
if (currentSession != null && currentSession.getMediaStreamManager() != null) {
currentSession.getMediaStreamManager().getLocalAudioTrack().setEnabled(isAudioEnabled);
}
}
此外,如果您想在不同的音频源之间切换:
public void onSwitchAudio() {
if (audioManager.getSelectedAudioDevice() != AppRTCAudioManager.AudioDevice.SPEAKER_PHONE) {
audioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.SPEAKER_PHONE);
} else {
if (audioManager.getAudioDevices().contains(AppRTCAudioManager.AudioDevice.BLUETOOTH)) {
audioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.BLUETOOTH);
} else if (audioManager.getAudioDevices().contains(AppRTCAudioManager.AudioDevice.WIRED_HEADSET)) {
audioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.WIRED_HEADSET);
} else {
audioManager.selectAudioDevice(AppRTCAudioManager.AudioDevice.EARPIECE);
}
}
}
