Question

我正在尝试制作应用detect when a new SMS is received 为此，我注册programatically a new BroadcastReceiver，我处理传入的短信，然后它应返回一个值，注册 BroadcastReceiver的片段应该检索。登记/> I can't get to retrieve the value returned from the BroadcastReceiver。我已经看到有关将值返回到Activities的其他StackOverflow问题，但它们总是最终创建一个新的Activity。我不希望这样。的 I want to get the value in the same place where I registered the BroadcastReceiver 即可。我该怎么做？

这是BroadcastReceiver的代码：

public class RegisterSms extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {

        // stuff...
        this.setResultData("data to return");

    }
}

在片段中我正在这样做：

BroadcastReceiver smsReceiver = new RegisterSms();
IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
this.getContext().registerReceiver(smsReceiver, filter);
// here I should be receiving the data sent by the BroadcastReceiver

将您的广播接收器设置为匿名内部类。

private BroadcastReceiver smsReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            //here you can parse intent and get sms fields.
        }
    };
IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
this.getContext().registerReceiver(smsReceiver, filter);

从BroadcastReceiver返回值
