I have attribute "attr1" defined for my views A, B, C. A and B are actually ViewGroups. Let's say C is contained in B and B in A. Is there an existing mechanism in Android framework that allows me to specify the value of attr1 in A and have it automatically propagated to B and C?

I like to know how can i clone a view object which is already there in the view hierarchy, so that it can be added to the same view hierarchy again.
View 1 Replies View RelatedI was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness.
I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc .
This all works great.
I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have
CODE:..........
The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple:
CODE:................
So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.

View 4 Replies View Relatedconnect / login are executed in the same thread of the caller, then are blocking - The packetlistener callbacks are called from smack receiver thread - The sendpacket enqueues the message to a queue. when I receive a message, I need to propagate it. I can use an handler, but it only gets the runnable object. How can I pass the data to the runnable called by the handler? I can't use a local variabile, because if I receive a lot of messages it will be overridden and I will loose some of them. Is it ok to use a queue to feed the runnable? Are there other techniques?
View 3 Replies View RelatedI'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
I'm developing a google maps based application for android 1.6.
My problem is that in my application I have more than one layer that extends from ItemizedOverlay representing information in the map.
The problem is that all the layers implement the onTap method, but now only the last layer (on the top of the stack) detects the tap event, so If the user taps on an item that is in a deeper item the method onTap never fires.
Is there any way to propagate the event to deeper layers?
Hierarchy Viewer tool is missing from my android-sdk-windows ools directory.
Link to tool: http://developer.android.com/guide/developing/tools/hierarchy-viewer.html
Should it be there is first place?
SDK Tools rev. 7, Platforms 7 & 8 packages are installed.
Is there a trick to getting the Hierarchy Viewer to work in landscape orientation, or is it completely broken? In Pixel Perfect View it shows my screen sideways (i.e. in portrait aspect ratio), but when I click on the views in the explorer area it outlines the wrong areas of the screen. It looks like the outlining assumes the display is in landscape orientation, so it outlines where the views would be if it were oriented correctly. Obviously fixing the display would be the best solution, but barring that I'm OK tilting my head if only the outlining would agree with the display. Anyone know a way around this?

If you're creating an activity, you can add add a hierarchy of views via setContent. however, if you're creating a custom component, you have to handle everything in the draw() overload.if i want to build a custom component that relies on a view hierarchy, is the model simply to create a hierarchy internally and then in draw call myViewHierarchy.Draw() or something?

File directory = _Context.getFileStreamPath("");
File subdirectory = new File(directory, "dir/mk/foo");
boolean result = subdirectory.mkdir();
How do I close a whole hierarchy of activities and show a new activity not present in the current task?
Context
Consider a FTP browser that resumes the previous session on launch. Each folder is displayed in its own activity. When I click on a folder, a new activity is started for the folder. If I press the back button, the app returns to the previous activity, which corresponds to the the parent folder.
I can logoff from the menu at any time. Logging off should bring me to the login activity (not present the current task when the app has resumed the session), and close all the other activities. How can I do this?
From what I've read, if the activity were in the current task I could use FLAG_ACTIVITY_CLEAR_TOP in the intent, but this is not my case.
I would be willing to bet that the vast majority of posts that are posted in the main Inc forum are for technical/troubleshooting of some sort.Or basically questions that need answers.So wouldn't it make sense to have the main forum actually be the troubleshooting forum and have the sub forum be "happy Inc thoughts.by Jack Handy"?you get the point.That's probably a lot easier on mods than constantly moving stuff.or labeling threads "moved"
View 9 Replies View RelatedI'm trying to compile an app via Android 1.6, and got errors shown below. It said some strings in TextView and Button are not localized. I know how to fix them. It's easy to add them to strings.xml. But I still doubt why I need to localize every string. I don't think the strings like '1024' (pure number) or '80 x 25' need to be localized. Can't I set some strings to be non-localized? I searched SDK 1.6 documents, but can't find any help.

I finally decided to use styles and themes instead of tediously setting attributes for each individual view. I was able to get the style to work when I set it on android:textAppearance, but when I try to just set it right on the style attribute like below, it no longer applies.This is happening to me for Buttons as well as TextViews. What I want is to be able to have a few different styles for text views and buttons and then just set the style on each button or text view.The style will need to define textSize, textColor, background and maybe a few others.Since background and some other things are not textAppearance,I need to use the general style attribute.
