Android :: Force Dialog Themed Activity To Be Modal
Feb 11, 2010
A button on our screen causes an activity to be shown that has a "dialog" theme. We are having an issue were if you click the button quickly twice in a row, the dialog activity is opened twice.
Typically I would expect that when a new activity is started, the underlying activity is immediately stopped, and thus accepts no further input.
However, since the dialog themed activity does not take over the whole screen, I think the underlying activity is only paused, not stopped and thus the buttons are still accessible.
Which brings me to my question... Is there a way to force the dialog themed activity into a modal state where the user can't click the buttons on the activity below?
I could probably manually accomplish this by disabling everything in onPause, and reenabling it in onResume, but this seems like a lot of work!

A lot of Android apps now display a modal dialog with the changelog (text) of the application (what's new in the latest version) the first time after it is installed or updated.
Does any one have example code on:
How to display a nice modal dialog suitable for scrollable text
How to make sure the dialog is only shown once
For 2. I assume SharedPreferences can be used for defining a preference "hasChangeLogBeenShownForVersionX" that is updated after the dialog has been shown. (though there might be a better way

I have a problem to start/create Activity in landscape mode. My Activity need to start in landscape mode and be used in landscape mode by users. So far, I used setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) to force screen orientation of my Activity to landscape mode in onCreate() method.
In addition to this screen mode requirement, my application need to start another background thread in onResume() method, and this thread takes some seconds in order to finish an initialization process, and it is not desirable to to stop/restart this thread's service during the initialization process.
However setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) forces my Activity restart in a very little while (means onCreate->onResume->onPause->onStop are executed twice at the first place). As a result, my background thread be stopped/restarted during the initialization process, and this makes me a mess at this moment.

In my current application I want to show a dialog having "Force Close" and "Report" option at the time of Unhandled Exception. Could anyone please let me know how to have this dialog? right now if I change default Exception Handler to mine It gets control but I am not able to show any dialog after that. I guess UI thread is already closed by the time handler gets control.

I feel a little bit silly asking this, but I haven't been able to find any answers on my own. My Force Close dialog has a "Report" button. I think it's a great idea, and I wish everyone had it. At first, I thought it must be something I turned on without realizing it, but not only can't I find any setting that I might have touched, I also can't find any reference to this button existing on the Internet. I have a Droid, and I know 4 other people with Droids, and they say they don't have the option to report Force Closes. Am I special? Am I just missing something? The "report" button has been there for at least a few weeks now.When I use the Report button, I get a screen with a "feedback" field and a checkbox for "Include system data". Below that , it says "Information from feedback reports will be shown to the developer of the application." Under that are Preview and Send buttons.As a developer, I've never received one of these reports.I'd try to send a report to myself, but it seemingly only shows the button for apps installed from the market, and I don't know of a way to crash my production app.I suppose I could publish a simple crashing app just to try it out, but I thought I'd ask you folks first.Edit:You can view screenshots here: http://bentobin.com/crashReportImages/

I'm very new to Android so I've been working primarily with information from the android developer's page. Everything was going great until I added the code from the alert dialog section. The code they give alone gives me an error when I try to run it on the last line, saying I must initialize dialog, but I feel like I'm getting the NullPointerException no matter what the case is.If I don't instantiate "dialog" to "null" at the beginning, I cannot run the program. I'm not even trying to do anything crazy yet, any help would be great because I'm having alot of trouble trying to figure out what exactly this code is trying to do.

I would like the users of my android app to have the option to email me the stacktrace of any uncaught exception that crashes my app. Originally I thought I would just wrap every entry point to my app in a try/catch block, but there are far too many of these even in my tiny app for this to be reasonable.So what I am really looking for is a way to specify some method to be the default handler for any uncaught exceptions.

I 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.

I am implementing a custom dialog to form an about screen with a simple look and feel (which may become more complex once I get it working). I have a xml layout that loads some text and an icon from R. However when ever showDialog(int) is called I get a force close. I followed the instructions as per the dev guide:
http://developer.android.com/intl/de/guide/topics/ui/dialogs.html
Code is as follows:
@Override
protected Dialog onCreateDialog(int id) { Dialog dialog;
switch(id) { case DIAG_ABOUT:
dialog = new Dialog(getApplicationContext());
dialog.setContentView(R.layout.aboutdialog);
dialog.setTitle(R.string.about_title);
dialog.setOwnerActivity(this);
break; default: dialog = null;
} return dialog;
} DIAG_ABOUT is defined as private static final int DIAG_ABOUT = 0;
The Log cat shows the following trace:
