Question

电话结束后，我必须打开另一个活动。但是，它没有捕获“呼叫结束信号”。

我在mTelManager和BroadcastReceiver中使用了Service，但它不起作用。

当服务或BroadcastReceiver打开活动时，它会显示MainActivity而不是目标。

源代码：

public class MainService extends Service{
TelephonyManager mTelManager;
PhoneStateRead pListener;
String TAG = "Call State catch";
boolean callOutState = false;   //calling state 

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onCreate() {
    Log.i(TAG, "ServiceReceiver->onReceive();");
    pListener = new PhoneStateRead();
    mTelManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    mTelManager.listen(pListener, PhoneStateListener.LISTEN_CALL_STATE);

    if(callOutState){   //if call end
        Intent showRecord = new Intent(getBaseContext(), Call_Out_Record_Activity.class);
        showRecord.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(showRecord);//open Call_Out_Record_Activity
    }
}

public class PhoneStateRead extends PhoneStateListener {
    private final String TAG = "Phone State Read";
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:
            Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> CALL_STATE_IDLE "+incomingNumber);
            break;

        case TelephonyManager.CALL_STATE_OFFHOOK:
            Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> CALL_STATE_OFFHOOK "+incomingNumber);
            break;

        case TelephonyManager.CALL_STATE_RINGING:
            Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> CALL_STATE_RINGING "+incomingNumber);
            break;

        default:
            Log.i(TAG,"MyPhoneStateListener->onCallStateChanged() -> default -> "+Integer.toString(state));
            break;
        }
        CatchCallState(state);
    }
}   

private void CatchCallState(int state){
    if(state == TelephonyManager.CALL_STATE_OFFHOOK || state == TelephonyManager.CALL_STATE_RINGING)
        callOutState = false;

    else if(state == TelephonyManager.CALL_STATE_IDLE)
        callOutState = true;
}

}

所以看起来你在这里有几个问题。首先，当您开始Service时，您正尝试开始活动 - 您应该执行以下代码：

if(callOutState){   //if call end
    Intent showRecord = new Intent(getBaseContext(), Call_Out_Record_Activity.class);
    showRecord.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(showRecord);//open Call_Out_Record_Activity
}

CallStateListener中的

。或者只是将其放在CatchCallState方法中。

接下来，请注意，没有＆＃34;呼叫结束信号＆＃34; - 手机将从＆＃34; OFF_HOOK＆＃34;到＆＃34; IDLE＆＃34;所以你需要标志来跟踪它。另外，请注意＆＃34; RINGING＆＃34;发生在来电，但不是拨出电话。因此，您可能希望根据来电或去电显示不同的消息。
