java - 如何将值从单个 View (布局)传递到多个 java 类？

Question

我正在我的应用程序中构建通知服务，为此，我创建了一个布局，允许用户输入日期(通过日期选择器)和时间(通过时间选择器)，并且值显示在 TextView 中。我有两个类，一个是主类(实现布局)

另一个是BroadcastManager类，

public class BroadcastManager extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    try {
        String yourDate //must define
        String yourHour //these two
        Date d = new Date();
        DateFormat date = new SimpleDateFormat("dd/MM/yyyy");
        DateFormat hour = new SimpleDateFormat("HH:mm:ss");
        if (date.equals(yourDate) && hour.equals(yourHour)){
            Intent it =  new Intent(context, MainActivity.class);
            createNotification(context, it, "Time to refresh", "Take a Deep Breath", "It's time for your daily meditation");
        }
    }catch (Exception e){
        Log.i("date","error == "+e.getMessage());
    }
}


public void createNotification(Context context, Intent intent, CharSequence ticker, CharSequence title, CharSequence descricao){
    NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    PendingIntent p = PendingIntent.getActivity(context, 0, intent, 0);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(context);
    builder.setTicker(ticker);
    builder.setContentTitle(title);
    builder.setContentText(descricao);
    builder.setSmallIcon(R.drawable.meditatebutton);
    builder.setContentIntent(p);
    Notification n = builder.build();
    //create the notification
    n.vibrate = new long[]{150, 300, 150, 400};
    n.flags = Notification.FLAG_AUTO_CANCEL;
    nm.notify(R.drawable.meditatebutton, n);
    //create a vibration
    try{

        Uri som = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Ringtone toque = RingtoneManager.getRingtone(context, som);
        toque.play();
    }
    catch(Exception e){}
}}

如您所见，我必须设置“您的日期”和“您的时间”变量，其值位于只能由主类访问的 TextView 中，如何在类之间共享这些值并解决此问题？

Ps-我正在根据此 Set notification for specific date and time 实现这些类

Answer 1

试试这个

Intent intent = new Intent("com.example.Broadcast");
intent.putExtra("date", datetime); 
sendBroadcast(intent);

在我的类(class)

public void onReceive(Context context, Intent intent) {
 String action = intent.getAction();

 if(action.equals("com.example.Broadcast")){
  String dateTime = intent.getExtras().getString("date");
 }
}

在你的 Android list 文件中

<receiver android:name="MyReceiver" >
<intent-filter>
    <action android:name="com.example.Broadcast" >
    </action>
</intent-filter>
