Question

我写了接收短信的申请在我写的AndroidManifest.xml中：

        <receiver
            android:name=".SmsReceiver">
            <intent-filter>
                <action
                    android:name="android.provider.Telephony.SMS_RECEIVED" />
            </intent-filter>
        </receiver>

收到的所有短信都由SmsReceiver类分析。

Class SmsReceiver：

public class SmsReceiver extends BroadcastReceiver
{
    private static final String SMS_RECEIVED = "com.example.remotecontrol.SMS_RECEIVED";
    private static final String SMS_CONTENT_KEY = "com.example.remotecontrol.SMS_CONTENT_KEY";

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Bundle bundle = intent.getExtras();
        SmsMessage[] message = null;
        String contentMessage = "";
        if(bundle != null)
        {
            Object[] pdus = (Object[]) bundle.get("pdus");
            message = new SmsMessage[pdus.length];
            for(int i=0; i<message.length; i++)
            {
                message[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                contentMessage += "SMS from " + message[i].getOriginatingAddress() + ": ";
                contentMessage += message[i].getMessageBody() + "\n";
            }

            Toast.makeText(context, contentMessage, Toast.LENGTH_LONG).show();
        }

        Intent intentSmsReceived = new Intent();
        intentSmsReceived.setAction(SMS_RECEIVED);
        intentSmsReceived.putExtra(SMS_CONTENT_KEY, contentMessage);
        context.sendBroadcast(intentSmsReceived);

    }

}

它接收短信并向程序发送意图。

        registerReceiver(new BroadcastReceiver()
        {

            @Override
            public void onReceive(Context context, Intent intent)
            {
                String contentMessage = intent.getExtras().getString(SMS_CONTENT_KEY);
                Toast.makeText(context, contentMessage + "text", Toast.LENGTH_LONG).show();
                //TODO
                //process SMS

                unregisterReceiver(this);
            }

        }, new IntentFilter(SMS_RECEIVED));

这部分代码采用意图和流程SMS并与应用程序进行交互。

如何取消注册Android Manifest中编写的接收器？它处理所有SMS-es，我希望它只处理一个正确的和关闭。

Answer 1

如果在清单中指定了广播接收器，则无法以编程方式取消注册。您需要将其从清单中取出并在代码中注册。

或者您可以将其注册并在onReceive的第一行添加检查。可能是通过布尔标志。

关闭清单中的接收器
