How to pass value from an activity in an broadcast receiver?

问题

How to read data from an activity in an broadcast receiver if the broadcast receiver is registered through the manifest file??? Please Help...

回答1:

First you need to store data in SharedPreferences and then get them into broadcast receiver.

You can use the code below in manifest file :

<receiver android:name=".YourReceiver">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
    </intent-filter>
</receiver>

and in code you can use :

public class YourReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
        {
            //updateWidget();
            SharedPreferences prfs = context.getSharedPreferences("defaul", 0);
            boolean bb=prfs.getBoolean("eer",false);
            alarm=context.getSharedPreferences("def", 0).getString("alarm_time","");
        }
    }
}

If you are calling broadcast receiver thru code then u can call it like as below

Intent intent1 = new Intent(context, TimeAlarm.class)
intent1.putExtra("var1", "value");
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0,
             intent1, PendingIntent.FLAG_ONE_SHOT);

Not getting value from activity to receiver class which extends Broadcast Receiver

Intent inte = new Intent();
    inte.setAction("MyBroadcast");

    inte.putExtra("Phone_number1", phoo1);
    inte.putExtra("Phone_number2",phoo2);
    inte.putExtra("Phone_number3", phoo3);
    sendBroadcast(inte);

Bundle extras = intent.getExtras();
        if (extras != null) {

          String phoo1 = (String) extras.get("Phone_number1");//getting null value
          String phoo2 = (String) extras.get("Phone_number2");
          String phoo3 = (String) extras.get("Phone_number3");
          System.out.println("Value Of Contact Numbers Outside intent in Reciver");
          System.out.println("Value Of First Contact Number"+phoo1);
          System.out.println("Value Of Second Contact Number"+phoo2);
          System.out.println("Value Of Third Contact Number"+phoo3);
}
