Question

我希望在接收短信时运行 ActivityIwanttoRun.class Activity，其中包含＆＃34;运行活动＆＃34; .. if语句正在运行当短信接收到包含文字＆＃34; RunActivity＆＃34; 时，给它留言。

但它没有显示Toast＆＃34;你已经召集了第二个活动＆＃34; ActivityIwanttoRun.class -

中的语句

任何人都可以告诉我这里有什么问题。我只是想看看我的活动 - ＆＃34; ActivityIwanttoRun ＆＃34;接收短信时运行。

IncomingSms.java

public class IncomingSms extends BroadcastReceiver  {

final SmsManager sms = SmsManager.getDefault();
@Override
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.contains("RunActivity")) {

                    int duration = Toast.LENGTH_LONG;
                    Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
                    Intent intent2 = new Intent(context,ActivityIwanttoRun.class);
                    context.startActivity(intent2);
                    toast.show();
                }
            }
        }

    } catch (Exception e) {
        Log.e("SmsReceiver", "Exception smsReceiver" +e);

    }
}

}

ActivityIwanttoRun.java

public class ActivityIwanttoRun extends Activity  {
private static final String TAG = "ActivityIwanttoRun";

   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    updateUI();
}

 private void updateUI() {

        Toast.makeText(this, "You have called your second activity",Toast.LENGTH_LONG ).show();

}

}

谢谢！

Answer 1

首先，您要启动 LocationActivity 而不是 ActivityIwanttoRun

更改

 Intent intent2 = new Intent(context,LocationActivity.class);
                    context.startActivity(intent2);

到

Intent intent2 = new Intent(context,ActivityIwanttoRun.class);
                    context.startActivity(intent2);

从Activity致电BroadcastReceiver的正确方法是

Intent intent2 = new Intent(context,ActivityIwanttoRun.class);
                    context.startActivity(intent2);
intent2.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent2);

Answer 2

使用此

Intent in = new Intent（）;

    in.setClassName("package name", "package name.ActivityIwanttoRun");

    in.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

    context.startActivity(in);

并提及互联网并接收短信作为清单的孩子的短信
