Android :: Switching Views With RadioButton And Saving Views In Bundle
Mar 6, 2010I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
Android :: Way To Persist Graphics On A Canvas (map Overlay)?
Feb 16, 2009I've been searching around and can't seem to find a way to do this properly. I am doing some tracking where I want to draw dots on a map overlay recording previous positions. When onDraw of the overlay is called it seems the canvas is cleared so I have to redraw all of the history on every invocation. This could result in several thousands of dots being draw over time which seems to not be very efficient. Is there some flag somewhere that I have not found which tells a map overlay to be persistent? Or is there some way I can save and restore the canvas so I'm only maintaining/drawing the current point on each onDraw?

View 1 Replies View RelatedSwitching Between Views With Sliding Menu?
Jul 14, 2013I'm currently developing an Android-app, in which I have already implemented an Slidingmenu (jfeinstein10's library). As above-views I have several activities I'd like to switch between with the menu-items in my Slidingmenu. For the most part, these activities consist of two fragments, a list and a content-view. In landscape-mode both are displayed, in portrait-mode only the list. Currently I'm switching between these activities with intents, which is not a very pretty "solution". How should I implement this?
View 1 Replies View RelatedAndroid :: Switching Between Views Without Loosing OnClickListeners
Aug 29, 2010On my application I'm developing, the main.xml layout (the default layout of my app) has a few buttons that have been assigned onClickListeners (not the implementation way). One of those buttons I want to have the ability to take you to another view. On the other view (preview.xml), there's another button that takes you back to the main.xml view. I've used setContentView in the onClickListeners of those buttons and this works fine so far, but after you click the button that takes you back to main.xml, the buttons on main.xml have lost their onClick functionalities. How can I get this to work right? I presume using setContentView isn't the right way to do this?

View 13 Replies View RelatedAndroid :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background
Jan 6, 2010I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

Android :: How Can Update The All The Views Inside A TabHost When Pressing On A ContextMenu Item From Within One Of The Views
Nov 16, 2010I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

Jan 25, 2010Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Feb 26, 2010I have rectangle white box. on cliking the rectangle I will draw a toolbar beneath the box and also call relayout to accomodate the toolbar ( size+100) ( i used surfaceview and in secondary thread i draw the toolbar) on click again on rectangle box it will disappear the toolbar and also has to resize the layout to original size (ie size-100) this is where I get stuck. I can disappear the toolbar however I cant call relayout either from secondary thread (says cant call from secondary thread). So I created a while loop in onlayout( this is where i create a thread to draw the toolbar) if i call requestlayout after while loop ends it doesnt do anything it doesnt call onmeasure etc.

The n900, the hd2, and a black berry i seem to re-call. Is there any reason why the desire wouldn't be able to do the same? I would love to play final fantasy 7, to the point at which i'm tempted to try out an n900 for a few days (i've only just received my desire and would still be able to cancel...), I'm aware they're not playing at full speed yet, but am more wondering if people think the desire would be capable of running a playstation emulator, should decent software be written in the future!
