我按照Record phone calls on android phone?的示例并将其放在 BroadcastReceiver 上以尝试录制MIC语音(我知道它仍然限于录制另一方),当电话呼入时传出。 我的问题是:当用户拿起电话时,我怎样才能获得状态。因为当它响起时,它也会转到“android.intent.action.PHONE_STATE”的动作。
我的代码:
public class PhoneCallReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
if (action.equals("android.intent.action.PHONE_STATE")
{
// Phone call recording
try {
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
recorder.setOutputFile(<my output dir>);
recorder.prepare();
recorder.start();
recordStarted = true;
telManager = (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
telManager.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
} catch(Exception ex) {
}
}
}
}
private final PhoneStateListener phoneListener = new PhoneStateListener() {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
try {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING: {
//
break;
}
case TelephonyManager.CALL_STATE_OFFHOOK: {
//
break;
}
case TelephonyManager.CALL_STATE_IDLE: {
if (recordStarted) {
recorder.stop();
recordStarted = false;
}
break;
}
default: { }
}
} catch (Exception ex) {
}
}
};
AndroidManifest.xml中的代码
<receiver android:name=".PhoneCallReceiver" android:enabled="true">
<intent-filter android:priority="1000">
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
基于Android 2.1 SDK并在HTC EVO 4G(Android 2.2)中测试

如果你想录制两端的声音(根据Android Docs)
recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);
我没有试过这个,但希望对你有用并回答你的问题,你看过getCallState()
的{{1}}函数了吗?

您可以使用android.intent.action.ANSWER
操作,而不是使用android.intent.action.PHONE_STATE
操作。您可以在应答呼叫时录制语音。
