I have some optional views in my xml layout. Namely a radioGroup and buttons. How can I hide these programtically?
View 2 Replies View RelatedI have a pretty standard search edit widget on top / search results list widget on bottom activity in my app. Below the results list widget I also have my view for ads. When the soft keyboard is brought up in this activity, I'd like to hide the view the ads are in because they consume too much screen space. I tried making that view android:isScrollContainer="true" but that had no effect.
So the question is, how can I ensure that certain views will be hidden when the soft keyboard is brought up?

Right - have now got a good reminder snooze app (calendar snooze) - but as mentioned here before it still cant do anything with tasks as android doesnt remind fully for tasks
so - im thinking of creating a calendar called 'tasks' and using this for task-events - and then not showing it in my normal calendar apps. it could mess everything up
one thought is will calendar apps be able to show differnt event filtering views with different widgets etc ?
ie: widget 1 shows normal calendar with 'tasks' filtered out widget 2 shows just 'tasks' calendar.
I am trying to add an animated spinner inside a EditText view to the right. And programmatically show/hide it.
I have created the animated spinner by introducing a linear interpolation rotation. code...
How do I ensure that I get the 'resize' behavior when the IME is shown/hidden?
I've included the following in my manifest:
android:windowSoftInputMode="adjustResize"
What else am I supposed to add? I've read that the container that the View is placed in should 'support resize' but what layouts support this?
Did they seriously not include a way to "hide" folders that you don't want showing up in albums? For example, it just searched my SD card and came up with an "icons" folder that contains various program icons. Is there seriously no way to tell it not to appear in HTC album? On windows mobile we had to resort to registry edits to correct this, but I'm afraid we can't do that on android... Also, is there serious no subfolders? So I can't have something like: Photographs -> Family -> Pets
View 5 Replies View RelatedI 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.
why CheckBox is always null.

I 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?
I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table
CODE:.................
I 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.
How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.
View 2 Replies View RelatedIs 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.

I have simple list to be filled in from the database along with a checkbox. I need a handle to all the checkboxes selected. Whn the CLEAR button is pressed at that point I need the row ids of all the selected check boxes to delete them. To do this :
My list.xml file looks like this :
CODE:......
and my data_entry.xml looks like this:
CODE:............
Now: I have list.java file where I am populating the list as follows:

How can I have a checkbox in my ui alter my ui live?
