How to raise an alert dialog from BroadcastReceiver class?

Question

I have used a timer method in an Activity class. In that method I have an intent from Activity class to a BroadcastReceiver class.

Answer 1

1) In Activity:

public static Context ctx;

onCreate {
    ctx = this;
}

public void showAlertDialog(Context context, String title, String message) {

    final AlertDialog alertDialog = new AlertDialog.Builder(context).create();
    // Setting Dialog Title
    alertDialog.setTitle(title);

    // Setting Dialog Message
    alertDialog.setMessage(message);

    // Setting OK Button
    alertDialog.setButton(DialogInterface.BUTTON_POSITIVE, "Okay",
      new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) 
        {
            alertDialog.dismiss();
        }
    });

    // Showing Alert Message
    alertDialog.show();
}

2) In BroadcastReceiver.onReceive:

YourActivity ac= new YourActivity ();
ac.showAlertDialog(YourActivity.ctx, "test", "test");
