Android :: AlertDialog Doesn't Display Items From ListAdapter Hide Options
Feb 25, 2010
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.

I'm referring to the "Downloads" tab in the Market app.
I've been noticing of late that it isn't listing the apps that I have been downloaded thus far. It displays one/two/three items that 've been downloaded (no specific time line, either). Furthermore, sometimes, it also tends to display an app which has already been removed.

Android has ListView component which is quite nice. The problem is that I created my own adapter to supply viewitems for each item displayed and I don't get anymore: Background color change when i scroll the items using up/down arrows. Background color change when I select an item. How do I do that?

How can I access items I previously set using AlertDialog.Builder?
private static final CharSequence[] skill_levels = { "Rookie", "Average", "Expert" };
skillLevelBuilder = new AlertDialog.Builder( this ); skillLevelBuilder.setTitle( "Change Skill Level" ); skillOnClick = new DialogInterface.OnClickListener() { [...] }

I'm using the following code from the apidemos..
CODE:................
Under /* User clicked Yes so do some stuff */, i'm not fed the isChecked variable.. however, I am given isChecked in the /* User clicked on a check box do some stuff */ section.. Obviously i don't want to update my SharedPrefs on checkbox click, in case the user hits cancel..So how do I get the checkboxs and values on the setPositiveButton onClick ?

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?

Why can't I use the Context of a Service to display an AlertDialog ?
I can do it with Toast!

I 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 have a simple list view with some check boxes in an alert dialog. I need to option to add a select all/none but you can't bring up the menu in an alert dialog, and I want to do this function from a button. From what I've seen any kind of button (positive, neutral, and negative) all close the dialog regardless.
So, is this possible? If no, what alternatives do I have? My last mitigation is to simply create a new view and recreate everything. Is a new view the best solution?

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've got this piece of code from an xml in my settings.apk (SecSettings actually) that contains tutorials on motion settings.
Code:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen android:title="@string/motion_tutorial_settings_title" android:key="parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<Preference android:title="@string/turn_over_title" android:key="turn_over" android:summary="@string/turn_over_summary" />
[Code] ......
In there, all the red parts contain tutorials on settings that don't actually work on my device, and for OCD sake, I don't want them appearing in my settings because of it. But simply cutting them out of that file will make the settings app crash whenever i open that menu
So question is: is there a way to hide these settings without impairing their functions?

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?

The items in the ListView comes from an AsyncTask. When the AsyncTask is running I want it to stop adding non-matching items. For now, if it had loaded 5 items and I search with a specified String, then when the AsyncTask continues loading items it adds automatically Orders to the ListView, even if there isn't a match.

For an Android application, I'm trying to use a Spinner which, when an option is selected, will hide/display relevant View objects. For my application, these objects are an EditText and an associated TextView label for the field. Unfortunately, I can't seem to get the EditText to hide/display, and when I add it code to hide/display the TextView, I get a NullPointerException. I presume that since I am laying out the view objects in a RelativeLayout, by hiding one of the view objects, I am removing its relationship with other view objects, hence the NullPointer.
Can anyone figure out why this might be happening? Here's my code...

I'm trying to place a set of Checkboxes within the same RadioGroup in a tabular fashion.I tried to have a couple of TableRow objects within the RadioGroup, but that removes the "group behaviour" and allows more than one Checkbox can be selected at the same time.I am able to put all the items on a single line (by setting the RadioGroup's "orientation" to "horizontal") but not in a grid like style.

I'm having a little difficulties while trying to get a certain layout to work: I want to have list. List does not have to be scrollable, but should be shown completely. But the page itself should be able to scroll (with the lists in it), if the total content ist higher than the screen.
CODE:.................
It only uses a small part of the screen (about 2 lines per list), instead of filling the available height, and the lists themselves can be scrolled. How can I change the layout to always show the whole lists but have the screen be scrollalbe?

There are some others applications doing this, like Twitter, Facebook, or even native applications such as Android Market. When you want to display a list of items retrieved from the internet, this looks like a standard way for displaying the user some notification about action in progress. This is a white background screen with an animated spinning wheel and a "Loading..." text. Does somebody know how to do this?. I've been able to do something similar with this code, but i don't like it too much yet.
Still work in progress:
