When your alarm fire than call activity you have to make transparent activity, and make dialog layout what you want. You can use AlarmManager and Broadcast Receiver for create Alarm.

Replace the Toast in the following code with a Dialog (http://developer.android.com/guide/topics/ui/dialogs.html)

public void onReceive(Context context, Intent intent) 
{   
    PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
    wl.acquire();

    // Put here YOUR code.
    Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); // For example

    wl.release();
}

Here is code for building a dialog:

AlertDialog.Builder builder1 = new AlertDialog.Builder(context);
        builder1.setMessage("Write your message here.");
        builder1.setCancelable(true);
        builder1.setPositiveButton("Yes",
                new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
            }
        });
        builder1.setNegativeButton("No",
                new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                dialog.cancel();
            }
        });

        AlertDialog alert11 = builder1.create();
        alert11.show();

I'm not sure if this is possible. Where are you trying to make/show your Dialog? Are you doing this on the BroadcastReceiver?

If that's the case then it probably won't work and you might want to change from using Dialogs to Notifications. This happens because Dialogs need an Activity.

This is the error I get when I try to shoot/create a Dialog from the BroadcastReceiver in the onReceive() method:

java.lang.RuntimeException: Unable to start receiver com.voxnet.autohop.helpers.AlarmReceiver: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not valid; is your activity running?
