View 1 Replies View RelatedAndroid :: Communicating Between Receiver Class And An Activity Class
Jul 14, 2010I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

Sep 8, 2010I'm new to Java and android development. In my application I need data which is accessible for a few activities. I've read that a good solution is to use Application class for this. So I use it like this:

Android :: Generic Task Manager Class For Application / No Dismiss Dialog
Nov 15, 2010I have a class which extends AsyncTask, which is intended to serve as a generic task manager class for my application. The strange behavior is that the progress dialog shows up, but is never dismissed. I am sure that onPostExecute() gets called for every task instance, as any Log.d("","") statements fire if placed in here, even the Toast messages show up from within this method, but I am not able to dismiss the static dialog. I understand that AsyncTask(s) have access to UI thread at only 2 places [onPreExecute() and onPostExecute()], so I think trying to dismiss the dialog in runOnUiThread() is unnecessary. All calls to executeTask() are made from different onCreate() methods of different activities that need to fetch some data over network before populating some of their UI elements, and I always pass the current activity's context to the tasks. As I do not switch activities until after the related tasks are completed, I believe the activity context objects are still valid (am I wrong to have assumed this???) I have never found any of them to be null while debugging.
Could this be a timing issue? I have also observed that most of the times DDMS shows all tasks get completed before the activity is displayed. If I use new Handler().postDelayed(runnable_which_calls_these_tasks,10); in the onCreate(), and add delaying code in foo_X(), the activities are displayed without any delay, but the dialog will just not dismiss(). I have read through quite a number of articles on this issue but am still not able to figure out exactly where am I going wrong. I do not want to define each task as private inner class Task1 extends AsyncTask<> in all of my activity classes and I would not want to (unless this is the only solution) load my application object with all activity references either as mentioned in this discussion: Is AsyncTask really massively flawed or am I just missing something?. I have spent a week on this and am absolutely clueless :( It would be great if someone can guide me, and let me know what am I missing. Following is the class definition: [I've removed some irrelevant application specific code for clarity]
public class NetworkTask extends AsyncTask<Void, Integer, Boolean> {
private Context UIcontext;
private int operationType;
private static ProgressDialog dialog;
private static int taskCount;
private NetworkTask(int operationType Context context){ this.UIcontext = context;
this.operationType = operationType;
if (taskCount++ == 0) dialog = ProgressDialog.show(context,"","Loading...");
}
public static Boolean executeTask(int operationType, Context context) { return new NetworkTask(operationType, context).execute().get();
} @Override protected void onPreExecute(){ super.onPreExecute();
if (taskCount == 1) dialog.show();
} @Override protected Boolean doInBackground(Void... arg0) { switch(operationType){ case TYPE_1: foo1();
break; case TYPE_2: foo2(); break;
case TYPE_3 foo3(); break; case TYPE_4: foo4(); break;
} @Override protected void onPostExecute(Boolean result) { super.onPostExecute(result);
taskCount--;
if (dialog.isShowing() && taskCount == 0){ dialog.dismiss();
}else { Toast.makeText(UIcontext, "Task#"+ operationType+", m done, but there are "+taskCount+" more", 5).show();
} } }

View 2 Replies View RelatedAndroid :: Spinner Selection Box On Activity And Dialog
Jun 22, 2010I have a spinner selection box on my activity, but now I want to remove the spinner from the main view and make the selection available by an option from the menu button. How do I get the dialog the spinner shows if I click it without having the spinner? Currently I fill the spinner using a SimpleCursorAdapter like this:
Cursor c = db.fetchAllSets();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this android.R.layout.simple_spinner_item, c, new String[] { DatabaseAdapter.SET_KEY_NAME }, new int[] { android.R.id.text1 });
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSetsSpinner.setAdapter(adapter);
So now I'm planning to remove the spinner from my activity, add a new button to the menu and in the onOptionsItemSelected(...) show a dialog with the list of available selection - just the way it is right now after clicking the spinner object.
