Android :: 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 :: Do Root Views Of An Activity In Android Have Any Prior Knowledge Of The Child Views That Will Be Loaded Into Them
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.

Aug 2, 2010I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException.

Here is what I have done:
The code for the onClick event of the ImageButtons:

mFlipper.setDisplayedChild(2);.............

Android :: Re Ordering Child Views Of A Layout
Aug 29, 2010I have a number of child views, each child is a TableRow and I need to be able to change the order of the TableRows, such that I can swap the rows into any order. I know there is a method called removeAllViews() but I don't really want to remove and re-create the views if its possible to access and change the order. I really want the display to update as smoothly as possible, taking the minimum amount of time, is it possible?
View 2 Replies View RelatedAndroid :: Why Add Child Activities To TabActivity Instead Of Simply Using Views
Mar 17, 2010I've been programming in Android for two years now and just joined an Android project where they are using a TabActivity to host multiple Activities. It's unclear why this is better than rewriting the TabActivity to simply use Views instead.
TabActivity extends ActivityGroup which means TabActivity can host both Activities and Views. But what's the use of this capability? I was under the impression that Activities should be treated as individual screens of an application.
In short, what is an example use case where it's recommended that TabActivity should host multiple Activities rather than multiple Views?

Android : Aren't Focus States Supposed To Bubble To Child Views?
Apr 19, 2010When using a View within a View, for example an ImageView within a LinearLayout, both of which have xml drawable resources (the LinearLayout as a background) specifying PNG drawables to use for the on/off states, shouldn't children Views receive the focus state when their parent gets focus? So as far as I understand, both my LinearLayout and ImageView should be switching to their focus states right? Apparently not Or, more likely, apparently my implementation is incorrect.
The focus state works on the LinearLayout but my ImageView never receives focus.. I have both Views set to android:focusable="true".
