Question

我试图在接收特定单词的短信（随机10个后者）时从另一个活动调用方法[方法名称验证（）]，该单词存储在名为： - vcode的字符串中。

     public class IncomingSms extends BroadcastReceiver {
    protected LocationManager locationManager;





public void onReceive(Context context, Intent intent) {
    final Bundle bundle = intent.getExtras();

     try {


        if (bundle != null) {

            final Object[] pdusObj = (Object[]) bundle.get("pdus");

            for (int i = 0; i < pdusObj.length; i++) {

SmsMessage currentMessage =     SmsMessage.createFromPdu((byte[]) pdusObj[i]);
    String phoneNumber =  currentMessage.getDisplayOriginatingAddress();

                String senderNum = phoneNumber;
                String message = currentMessage.getDisplayMessageBody();



    if (message.equals(vcodei)) {
    int durationge = Toast.LENGTH_LONG;
  Toast toastge = Toast.makeText(context, "Verifyed ", durationge);
   toastge.show();

   mainpageactivity mp = new mainpageactivity() {
        public void launch() {

            this.verifyed();

     }
   };


   }


  } 

    } catch (Exception e) {
        Log.e("SmsReceiver", "Exception smsReceiver" +e);
           int durationg = Toast.LENGTH_LONG;
                Toast toastg = Toast.makeText(context,"map error"+ e     , durationg);

                                toastg.show();   
    }


}




}

我的第二个活动如下，我提到了导入，需要调用该方法......

                         WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.mainpage);

    register_btn= (Button) findViewById(R.id.register_btn);        
    countryCode_txt =(EditText) findViewById(R.id.countryCode_txt);

      Toast.makeText(getApplicationContext(), "Now what..",


                Toast.LENGTH_LONG).show(); 

      Intent register = new Intent(mainpageactivity.this, BroadcastNewSms.class);
     startActivity(register);
      mainpageactivity.this.finish();


                }

     }

AndroidManifest.xml如下：

请回复您的宝贵帮助... 我是android的新手..

Answer 1

要开始活动，您应该使用Context.startActivity(intent)。请参阅下面的完整代码

Intent intent = new Intent(context,mainpageactivity.class);
context.startActivity(intent);

Answer 2

您保持广播接收器不变，并在其中添加广播意图，而不是：

mainpageactivity mp = new mainpageactivity() {
    public void launch() {

        this.verifyed();

 }

你删除了那个并且你输入了这段代码：

            // this intent will call the activity whih will lunch your methode
            Intent broadcastIntent = new Intent();
            broadcastIntent.setAction("com.appname.SMS_RECU");

            context.sendBroadcast(broadcastIntent);

然后在您的活动中，您可以在活动定义之后直接定义您的receiver和intentFilter：

SmsReceiver broadcastReceiver;  

IntentFilter intentFilter = new IntentFilter();

然后在onCreat中实例化你的接收器：

broadcastReceiver = new SmsReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {

                    /*you call your methode*/
                verifyed();
            }
        };
registerReceiver(broadcastReceiver, intentFilter);

你还创建了一个intentFilter，它将由onCreat中的broadcastReceiver调用：

intentFilter.addAction("com.appname.SMS_RECU");

你在onResume注册你的接收者：

@Override
protected void onResume() {
    super.onResume();
    registerReceiver(broadcastReceiver, intentFilter);
}

你取消注册你的接收者，在onPause：

@Override
    protected void onPause() {
        super.onPause();
            unregisterReceiver(broadcastReceiver);
    }

删除您在manifest.xml中添加的接收者和intentFilter，您不再需要它了。我希望它对你有用。
