Question

我是android的初学者，我正在开发一个应用程序，每当用户拨打电话时，BrocastReceiver就会启动...我正在尝试监控广播接收器内的网络状态......我正在尝试启动活动当用户挂断电话时...但遗憾的是它给了我一个错误...请让我知道怎么做...

我的广播接收器在用户拨打电话时正常启动...但我不知道如何在用户通话时监控BroadcastReceiver内的网络..并在用户挂机时调用BroadcastReceiver的活动电话......

请让我知道如何实现这一目标...提前致谢..： - ）

我的代码......

BroadcastReceiver代码

 public class MoniterNetworkStatus extends BroadcastReceiver{

private ConnectivityManager connectivityManager;
private NetworkInfo info;

@Override
public void onReceive(Context context, Intent intent) {

    Toast.makeText(context, "Monitering Network Status !!!", Toast.LENGTH_LONG).show();

    boolean networkStatus = false;
    TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);


    Intent activityIntent = new Intent(context, NetworkStatusActivity.class);

            // I am monitoring the network status as long as user is on call...
    while(telephonyManager.getCallState()!= TelephonyManager.CALL_STATE_IDLE){

        info = connectivityManager.getActiveNetworkInfo();
        if(info == null){
            networkStatus =  false;
        }else if(info.getType() == ConnectivityManager.TYPE_MOBILE){

            networkStatus = info.isConnected();
        }else{
            networkStatus = false;
        }
    }



    //Putting the network details in to the activity.   
    activityIntent.putExtra("operatorName", telephonyManager.getNetworkOperatorName());
    activityIntent.putExtra("networkStatus", networkStatus);

            // starting the activity
    context.startActivity(activityIntent);
    abortBroadcast();

    }
}

Answer 1

您需要注册另一个接收器才能接受ACTION_PHONE_STATE_CHANGED。这可能是Detecting outgoing call and call hangup event in android

的副本

从广播接收器调用活动
