How does one access a particular widget from within a custom layout while using Alert Builder? As you can see below, I'm setting the alert to a widget that is created in the code, but I'd MUCH rather use predefined layout.
Current code:...................
However, whenever I try to do it the second way I get a null pointer exception.

I have the following snippet of code, i'm trying to get the text values someone types into the EditText's
CODE:............................
My login.xml is pretty standard and straight forward
CODE:........................
So when someone clicks the PositiveButton, how do i get the value of the EditText fields?
Since Android supports styles and it's good practice to use them (similar to CSS), I made a new style and applied it to 3 buttons.
The Layout builder in Eclipse did not register the changes and either broke (showed nothing) or didn't apply styles at all.
After running the app in the emulator, styles are correctly applied.
So is there something I'm missing or the Android plugin doesn't support styles?
So this is related to a question I asked earlier. I am trying to display an alert using a specified layout. My layout is:
And the code to call and show the alert dialog is..
When I run it I get an error saying:
Uncaught handler: thread main exiting due to uncaught exception
android.view.WindowManager$NadTokenException: Unable to add window -- token null is not for an application
I've looked through the android development site and can't figure it out. I think I'm just missing something obvious but the fix isn't jumping out at me. How can I get this alert dialog to display?
I want to change the alert sounds for various events: email notification, SMS, power status, Google Talk, etc. I can change the alert sound via Settings->Sound & display->Notification ringtone, but the sound is identical for all the various notifications which seems ridiculous. Is there an app or widget which allows me to assign different notification sounds to different events?

I'd like this this button to toast a message. However, as soon as I try add the code to define the OnClickListener, I get a force close message.Does this mean one Activity can only access one screen/layout?

I only need the ringer on. I just want an easy way to turn off the notifications and alerts rather than having to open up the options every night.

By default it is taking layout main.xml file itself of layout. Its not pointing to layout-largemain.xml. its throwing exception:Activity can not start resource not found. So can any one guide me how can I acheive this and how to support mutiple screens with different layouts like large,small and default along with images specified in respective dip folders.

Now, the Google Search home screen widget has an EditText, so it's obviously legal to implement.
I have read the Android UI trick 2 on Android developers, which tells people how to include a layout in another layout file multiple times, and give these included layouts different id. However, the sample here is overwriting the layout id, not the id of the views IN this layout. For example, if the workspace_screen.xml looks like this: And I include it three times in another layout file. Do I end up with three TextViews with id firstText, and another three with secondText? Isn't there an id collision? And how do I find the secondText TextView in the third included layout with findViewById? What should I input in the findViewById method?
View 1 Replies View RelatedLet's say that I have two layouts for a widget: Layout1 and Layout2. The default for the widget is Layout1, but I allow the user to choose which layout they want the widget to be. So if the user changes to Layout2, how do I programmatically change the layout to Layout2? There isn't a setContentView method for widgets like there is for Activities.
View 2 Replies View RelatedI have this really annoying problem:In my widget, i would like to change the background by code. I noticed on the Google doc than I can easily change the background of an Imageview: remoteViews.setImageViewResource (R.id.my_iv, R.drawable.my_bg);Ok, too easy, i want to change now the Linear layout.. What I read about the remoteview id that I can change a Bitmap, Int, Bool, String, etc. but not a drawable. So i guess i cannot use:remoteViews. set Bitmap (R.id.my_ll, "setBackgroundDrawable",BitmapFactory.decodeResource(context.get Resources(), R.drawablemy_bg));I am totally disapointed and tried a last idea: views.setInt (R.id. my_ ll,"setBackground Resource" ,R.drawable.my_bg);But The logcat told me: android. widget. Remote Views $Action Exception: view: android. widget.LinearLayout can't use method with RemoteViews:setBackgroundResource(int)I am totally lost and I really don't know what to do.
View 1 Replies View RelatedI am trying to make a widget to show on the home screen(s). My problem is lets say I set my icon to 30x30 when I load the widget on the screen the Icon is the correct size but the layout itself takes up a lot more space than what is actually needed. This means that I can't really place my widget next to other icons on the screen. Its like the bounding box is 3 times bigger than the content that fills it.
Here is my XML
[CODE]
I have tried wrap_content and other width/height settings but nothing seems to reduce the "Box" around my widget content. I clicked on my ATK widget and started to drag it around on my HTC Aria and it shows the bounding box around the widget and that one is the same size of the content inside same with all the other widgets on my screens.
I can write a widget with a Button or ImageButton and assign a StateDrawable as background or sourcein order to make an effect when you click it. Besides that I have problems with the side of each button, my main problem is this: how do I change the StateDrawable if I want to change the image of the button from the AppWidgetProvider but still want to preserve the click effect like a StateDrawable. The power control widget in Android does things like that.
View 2 Replies View RelatedI have defined custom views in the various layout .xml files. However, all the layouts are using the Linear Layout - put the content would vary.
I would like to create my own widget tag something like <com.mypackage.MyLinearLayout />, I would like to pass the layout as a param to the <com.mypackage.MyLinearLayout layout="@layout/simple.xml" />
How to define new attributes to the custom widgets ? Simply defining a getter/setter method would work or is there any other references.
I like the layout of the toast widget very much, that means rounded corners, transparency, light grey border. Is there any way to see the layout parameters of such android standard widgets like the toast? I would like do define a TextView with the same layout parameters.

I cannot find any information on how to change or hide the background image.
I'm sure I'm not the first one to say this, but for goodness sakes, we need a very good Android UI builder plugin for Eclipse or whatever other java tools developers are using. A nice toolbox docked on the side where I can drag and drop controls to the screen/form and then allow me to set the properties in the prop inspector and then create events, etc. I've got ideas for some business applications and I HATE having to deal with main.xml. Droid Draw is okay, but it is a far cry from having a good UI plugin.
View 4 Replies View RelatedWith a home screen widget I'm trying to layout. Basically, I'm trying to layout my widget so it matched a standard home screen application shortcut perfectly. Basically, at this point, I'm about ~2px off. Has anyone got this to match up just right? Should I be able to find this layout in the source somewhere? Here's my layout thus far:

View 4 Replies View RelatedI'm parsing a document with large text field. In my characters section I am using StringBuilder
currentStory.append(ch, start, length);
then in my endElement i'm assigning it to the appropriate field on my object.
if (name.equals(tagDesc)) { inDesc = false;
if (currentItem != null ) { currentItem.setSummaryText(currentStory.toString());
} currentStory.setLength(0);
} setSummary is public void setSummaryText(String text) { Story = text;
}
And I am running out of memory. If I change setSummaryText to something completely weird like this:
public void setSummaryText(String text) { char[] local = text.toString(
) Story = new String(local);
}
I am fine. I just cant figure out where I am holding that reference?
Story is a member var of this object initialized with "";
Note - assigning to local String variable instead of char[] - fails as well.
I have the same problem with Gesture Builder on the emulator and when I build the app myself and install om my G1.
It does not save the gestures correctly on my sdcard. It does not create a folder called "gestures" but instead creates a file called "gestures" with a size on about 2kb. It does not grow when I create more gestures. Is this really correct, because I thought a folder would be created in which each gesture would be stored in different files.
I look in code for CreateGestureActivity.java and here is where the magic of saving happens:
final GestureLibrary store = GestureBuilderActivity.getStore(); store.addGesture(name.toString(), mGesture); store.save();
I have already developed some widgets for android, but every time, I have the same problem... I Can' access my XML layout's elements from my java code. For example :

</LinearLayout>
With this layout, how can I access my "myTxt" object?
I'm looking for a clock widget that looks good in both portrait and landscape modes. I'm tired of clock widgets that look like crap when the launcher is in landscape mode (or, if they look good in landscape, they look like crap in portrait), like HD Widgets or Beautiful Widgets.
I've only found one widget that changes its layout completely (read: not just stretches in one dimension and contracts in the other) to adjust itself to its new allocated area: Accuweather. See the attached images for what I mean. Notice the layout is completely different, and nothing overlaps/looks stretched/tiny. Both modes look great.
Now, my problem with Accuweather is that I'm looking for something darker, that looks better with the wallpaper. Do you know of some widget that does the same as Accuweather (different layouts for portrait/landscape) and allows customization?
