每次创建活动都会触发警报管理器

Question

我正在创建一个警报管理器，该警报管理器每天都会在午夜更新数据库，并更改我正在从事的活动中的某些textViews。每次打开应用程序时都会调用此警报管理器。如果在我的onReceive函数中仅放一个Toast，它将正常工作，但是，如果我包含其他代码，则每次打开应用程序时它将返回被触发。 这是我的BroadcastReceiver：

package com.example.bleh.myapplication;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.TextView;
import android.widget.Toast;

import com.example.bleh.myapplication.DB.AppDatabase;
import com.example.bleh.myapplication.DB.Plan;
import com.example.bleh.myapplication.DB.User;
import com.example.bleh.myapplication.Utils1.FormulaUtils;
import com.github.lzyzsd.circleprogress.DonutProgress;

public class AlarmReceiver extends BroadcastReceiver {

    public AppDatabase mydb;
    Plan plan;

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm worked.", Toast.LENGTH_LONG).show();
        mydb = AppDatabase.getInstance(context);
        final long planid = intent.getExtras().getLong("planid");
        final long userid = intent.getExtras().getLong("uid");
        final String requirements = intent.getExtras().getString("requirements");
        Log.wtf("PlanId: ",planid+"");
        Log.wtf("UserId: ",userid+"");
        Log.wtf("Requirements",requirements);
        plan = mydb.getPlanDao(context).getPlanById((int) planid);
        final User user = mydb.getUserDao(context).getUserById((int) userid);
        plan.setCurrentWeight(FormulaUtils.reCalculateWeight(plan.getCurrentWeight(), Double.parseDouble(requirements)));
        plan.setBmr(Double.parseDouble(FormulaUtils.calculateBmr(user.getSex(), plan.getCurrentWeight(), user.getHeight(), user.getBirthDay())));
        plan.setNbOfDays(plan.getNbOfDays() - 1);
        mydb.getPlanDao(context).update(plan);
//         Calculate all data before sending to feature2 activity
        String requirement = FormulaUtils.CalulcateDailyRequirements(plan.getWorkoutPerWeek(), plan.getBmr());
        String day = plan.getNbOfDays() + "";
        float progress = 0F;

        // Start feature2 activity with updated data
        Intent updateFeature2Intent = new Intent(context, feature2.class);
        updateFeature2Intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP); // Add this flag
        updateFeature2Intent.putExtra("requirement", requirement);
        updateFeature2Intent.putExtra("day", day);
        updateFeature2Intent.putExtra("progress", progress);
        context.startActivity(updateFeature2Intent);
    }

}

这是我的功能活动：

public class feature2 extends AppCompatActivity {

    public AppDatabase mydb;
    TextView BMR,requirements,days;
    Button addfood,addex,nextday;
    LinearLayout mainLayout;
    Button Meas,Bluetooth;
    DonutProgress donutProgress;
    Plan plan;
    int BreakfastAverageCalories = 350;
    int LunchAverageCalories = 500;
    int DinnerAverageCalories = 350;

    // Add this method
    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);

        // Get data from intent
        String requirement = intent.getStringExtra("requirement");
        String day = intent.getStringExtra("day");
        float progress = intent.getFloatExtra("progress", 0F);

        // Update UI
        TextView requirements = findViewById(R.id.requirements);
        TextView Days = findViewById(R.id.days);
        DonutProgress dailyProgress = findViewById(R.id.donut_progress);

        requirements.setText(requirement);
        Days.setText(day);
        dailyProgress.setProgress(progress);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_feature2);
        Intent intent = getIntent();
        requirements = findViewById(R.id.requirements);
        donutProgress = findViewById(R.id.donut_progress);
        days = findViewById(R.id.days);
        final long planid = intent.getExtras().getLong("planid");
        final long userid = intent.getExtras().getLong("uid");
        mydb = AppDatabase.getInstance(feature2.this);
        plan = mydb.getPlanDao(feature2.this).getPlanById((int) planid);
        String requiredCalories = FormulaUtils.CalulcateDailyRequirements(plan.getWorkoutPerWeek(), plan.getBmr());
        Double CaloriesRequired = Double.parseDouble(requiredCalories);
        BreakfastAverageCalories = (int)(CaloriesRequired*0.25);
        DinnerAverageCalories = (int)(CaloriesRequired*0.25);
        DinnerAverageCalories = (int)(CaloriesRequired*0.25);
        try
        {
            requirements.setText(FormulaUtils.CalulcateDailyRequirements(plan.getWorkoutPerWeek(), plan.getBmr()));
        }
        catch (Exception ex)
        {
            Log.wtf("There is no plan","!");
        }
        Intent intent1 = new Intent(this, AlarmReceiver.class);
        intent1.putExtra("uid", userid);
        intent1.putExtra("planid", planid);
        intent1.putExtra("requirements",requirements.getText().toString());
        Calendar updateTime = Calendar.getInstance();
        updateTime.setTimeZone(TimeZone.getTimeZone("GMT"));
        updateTime.set(Calendar.HOUR_OF_DAY, 0);
        updateTime.set(Calendar.MINUTE, 0);
        updateTime.set(Calendar.SECOND,0);
        Date milliseconds = updateTime.getTime();
        long millis = milliseconds.getTime();
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 5555,
                intent1, 0);
        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, millis ,AlarmManager.INTERVAL_DAY, pendingIntent);
   }
}

这是我的清单：

<receiver android:name=".AlarmReceiver"
            android:enabled="true"
            android:exported="true">
        </receiver>
