Android-发生拨出电话时，会自动抛出OFF_HOOK状态

Question

在打出电话的情况下，会自动抛出OFF HOOK的状态嗨，大家好，首先我要为我的英语道歉。

好吧，在我的应用程序中，我正在监视之前和之后的每个呼叫。 但是就在呼叫开始之后，所以我对“振铃”状态无关紧要，但是我的应用程序正在触发假的“摘机”状态。 当我拨打电话（去电）时，我的应用会在振铃后立即将状态设置为摘机。 这样，我可以监视一个我不应该呼叫的呼叫，因为该呼叫无法应答。

有人已经有这个问题了吗？

AndroidManifest.xml

    <receiver
        android:name=".CallStateBroadcastReceiver">
        <intent-filter>
          <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
    </receiver>

    <receiver
        android:name=".OutgoingCallBroadcastReceiver">
        <intent-filter>
          <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

CallStateBroadcastReceiver：

    CallStatePhoneStateListener phoneListener = new CallStatePhoneStateListener(context, intent);
    TelephonyManager telephony = (TelephonyManager) context.getSystemService(
            Context.TELEPHONY_SERVICE);

        telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);

CallStatePhoneStateListener：

@Override
public void onCallStateChanged(int state, String incomingNumber) {

    switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:

            // do something
            break;

        case TelephonyManager.CALL_STATE_OFFHOOK:

            // do something
            break;

        case TelephonyManager.CALL_STATE_RINGING:

            // do something
            break;
}

OutgoingCallBroadcastReceiver：

@Override
public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    if (bundle == null)
        return;

    String number = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    // just save the number
}

Answer 1

采取静态字符串，例如：-prev_state并在每种情况下将电话的状态存储在该字符串中，如果您想知道如何断开呼出电话，则应执行以下操作：

   if(state==TelephonyManager.CALL_STATE_IDLE)
{ Log.d(TAG, "CALL_STATE_IDLE==>"+incoming_nr);
                      {
                   if((prev_state==TelephonyManager.CALL_STATE_OFFHOOK))
                             {  
                        prev_state=state;  
                       // do something when the Call  is ended 
                              }
                       }
}

希望能帮助到你 ：）
