当由被叫用户接收到的呼出的Andr​​oid检查 [英] Android check when outgoing call is received by callee

问题描述

我正在开发的Andr​​oid框架，

I'm developing on android framework,

我想在由被叫方接收的呼出呼叫到触发事件，以及当所述呼叫结束（在任何双方）

I want to fire an event when an outgoing call is received by the callee , and also when the call is ended (from any of the two sides)

推荐答案

中序知道wheter主叫方已收到呼叫时，您将需要创建一个监听器。

Inorder to know wheter the calling party has recieved the call, you will need to create a listener.

class PhoneInfo extends BroadcastReceiver {
/**
 * Getting the System Telephony Service and registering a listener for Voice Call state
 */
@Override
public void onReceive(Context context, Intent intent) {
    IncomingCallListener phoneListener = new IncomingCallListener();
    TelephonyManager telephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    telephony.listen(phoneListener, PhoneStateListener.LISTEN_CALL_STATE);
}

class IncomingCallListener extends PhoneStateListener {

    public void onCallStateChanged(int state, String incomingNumber) {
        Log.i(logcat,"CALL_STATE changed " + callflag);

        switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:
            Log.i(logcat,"CALL_STATE_IDLE");
                                    //This is where call ends.
            break;

        case TelephonyManager.CALL_STATE_OFFHOOK:
                                    //This is where we know call is established
            break;

        case TelephonyManager.CALL_STATE_RINGING:
            Log.i(logcat,"CALL_STATE_RINGING");
            break;
        }


    }

}

与作为你的活动注册此
phoneInfo =新PhoneInfo（本）;
registerReceiver（phoneInfo，新的IntentFilter（Intent.ACTION_NEW_OUTGOING_CALL））;

使用日志现在ü可以看到呼叫时拨打或接收状态被改变。

Now with Logs u can see how states are changed when a call is dialed or received.
