I am trying to display menu options while showing an AlertDialog i.e. when MENU key is pressed, it should show whatever options that have been created. I read the following in the Dev Guide at....................

When I try to set the Alert using ArrayAdaptor to display a set of items, the list is displayed but the items' characters are invisible. If the item is selected, then the characters are visible. Scratching
my head on why. Appreciate any advice.
Below is the code and the screenshot from the emulator.

In the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class.
In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on.
The below code is the onTap method I've written. It functions as written but doesn't yet do what I'd hope. I'd like to capture and persist each selection made by the user to be used later. How do I do that? Is using an AlertDialog in this manner a good idea? Are there better options?

I've been working at this all day, and I'm really close but just can't get this to work. I have a button that pulls up an AlertDialog populated with saved entries that include Name and Price. Right now, I can click an item in the Dialog and have it automatically fill in the Name and Price fields in my activity. I want to also be able to long press an item and receive an option to delete it. This is my first try at an Android app, and a lot of this is repurposed from the Notepad Tutorial. Two things I can't figure out:
1) Is my registerForContextMenu sufficient/correct?
2) What am I doing wrong with my onCreateContextMenu? Code...
I have an Options menu up and running in my Android application and I've overridden the onCreateOptionsMenu, onOptionsItemSelected and onPrepareOptionsMenu methods to customize the menu a little. My question is related to keeping the Options menu open after the user clicks on a menu item. Basically, I'd like to be able to hide the menu until the user clicks on the device menu key. Once the user clicks on this key, I'd like to be able to hold the menu in place regardless of how many times the user clicks on menu items. If the user wants to hide the Options menu, they'd just need to click on the device menu key again. Is this type of interaction supported (or even advisable).

I can do it with Toast!
In my app I bring up a context menu on long click in a ListActivity. One of the options "Priority" pops up an AlertDialog with 3 radio button choices. The problem is, it displays an empty dialog box without my 3 choices, or the message that I set. Here is my code...

Android question. If i create an Options menu with menu.xml, can I change the menu buttons' standard text size, color etc using xml? I would like to change text size, bold, and color. I would like to avoid using themes and styles for this application.
View 1 Replies View RelatedI have issue with displaying AlertDialog from Service. I am able to display custom layout window using Toast or using WindowManager(TYPE_SYSTEM_ALERT or TYPE_SYSTEM_OVERLAY). But, I do not want to use custom layout, I prefer to use nice AlertDialog GUI directly.
Scenario:
Running Service. No active Activity present. On some external event, Service sends Notification
When user press Notification, Service is informed via PendingIntent and AlertDialog should be displayed (created with AlertDialog.Builder(this))
Error: ERROR/AndroidRuntime(1063): Caused by: android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application. Searching for the answer lead me to impression that I am trying something that is currently not possible (Android 2.2). Or maybe it is.
I am new to Android and this is my first question here so please go easy on me.
Is it possible to check some condition inside onCreate() of an Activity and display an AlertDialog?
I am creating an AlertDialog anonymously in Oncreate() and calling show on that instance but the AlertDialog is never displayed.
I was trying to set up my options menu so that there would be 2 buttons on the 1st and 2nd row and then 1 button on the 3rd row. Here is the code I was trying to use but I'm guessing groupID argument isn't what I thought it was.
menu.add(1, MENU_NAME, 1, "by Name");
menu.add(1, MENU_NUMBER, 2, "by Number");
menu.add(2, MENU_POSITION, 1, "by Position");
menu.add(2, MENU_COLLEGE, 2, "by College");
menu.add(3, MENU_UPDATE, 1, "Update Roster");
Maybe this is solved somehow with the XML Layout but I'm not really good with the layouts ;( So I managed to not get too far that way either.
In my application, I have extended SurfaceView and ListView. I create a LinearLayout as below
mainForm = new LinearLayout(this); mainForm.setOrientation(LinearLayout.VERTICAL); mainForm.setLayoutParams(new LinearLayout.LayoutParams( LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
I then add the SurfaceView and ListView to the mainForm and then setContentView(mainForm);
I also override onPrepareOptionsMenu and call menu.clear() and then dynamically create menus each time the menu button is pressed by the user. The application loads fine and the SurfaceView works fine as I directly draw images to it in a sleep loop. The ListView displays items and is desined to refreshed with new items. The options menu also displays once as well................................
I am trying to manage the options items, making one button visible and another invisible based on whether a background service is active.

I am trying to figure out what is the best way to go about creating dialogs. I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation?

View 2 Replies View RelatedI created a basic options menu, here an example of creating an element of me menu: menu.add(0, MENU_BACKWARD, 0, "").setIcon(R.drawable.btn_backward);
As you can see I don't want to show any text in this menu, just an icon ! But when the menu is showed, there is a "ugly" blank under the icon (the text is supposed to be there) and I want to avoid this. A least if it's possible to center the icon the options menus, it will be great.
I'm trying to change the default color for the options menu which is white. I want a black background for every item on the options menu. I've tried some shoots like android:itemBackground="#000000" on the item element within the menu element but it doesn't work. I don't know if this is doable or not. Any idea would be welcome! :)

View 2 Replies View RelatedI wanted to create a static options menu for all my activity screens. I dont want to override onCreateOptionsMenu() in each activity. Since Menu class is an interface with a huge number of methods, its difficult to create a static object of the implementing class.
View 3 Replies View RelatedI want to use addIntentOptions to drive my menus when ever possible. This seems the cleanest way to provide them.
