java - 开始接收短信的 Activity

我想在收到包含“运行活动”的短信时运行activityiwanttorun.classActivity。当收到包含文本“runactivity”的短消息时，if语句在祝酒时工作。
但是它没有在activityiwanttorun.class中显示toast“youhavecalledyoursecondactivity”语句--
有人能告诉我这里出了什么事吗..我只想看到我的活动-“activityiwanttorun”在收到短信时运行。
incomingsms.java中

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);

    }
}

}
活动iwanttorun.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();

}

}
显示

<?xml version="1.0" encoding="utf-8"?>

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity android:name=".ActivityIwanttoRun">

    </activity>

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

谢谢您！

最佳答案

首先你要启动LocationActivity而不是ActivityIwanttorun
改变

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

到

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

从Activity调用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);
