View 2 Replies View RelatedAndroid :: IconPreferenceScreen That Extends PreferenceScreen
Jul 28, 2010I would like to have a Preferences activity that has icons like the system settings has had since Eclair. It uses a special Preference called IconPreferenceScreen.I can copy that into my project without problem, but I'd like the behavior of the PreferenceScreen instead of just the Preference Class. I could like to click on it to show its children Preferences. I thought it would be a easy to change to make IconPreferenceScreen extend PreferenceScreen instead of Preference, but PreferenceScreen is Final.Why on earth would google make PreferenceScreen a final class? Is there anyway to achieve what I would like to do, short of dividing up my Preference into several other Preferences that all receive intents (That's how the system settings works.)

Android : Layout - Content Extends Over The Visible Area
Dec 27, 2009Currently I'm working on a dialog which consists of title, description, tags and footer. The title can be long and in this case the text should automatically be displayed in multiple lines. The description is also longer and should fill multiple lines.
At the bottom of the dialog has to be the footer (also if the title and description don't fill whole screen).
I tried to do create the layout described about but had a problem with long text - if the content is long it doesn't display multiple lines but extends main view (LinearView) so the content extends over the visible area.
Here I'm pasting the print screen of the current state and the mockup of the desired layout:
TextView "Footer" and buttons OK and Cancel should appear at the bottom of the screen and the title ("Title Title Title...) and description text should automatically appear in multiple lines instead of extending the parent view.
Android :: Simple Program - Class Extends Activity At Startup
Oct 1, 2010I have a simple activity program in android. Basically the class just extends Activity.
But when I start it I get a ClassCastException in the constructor of my class. I don't even have a constructor defined, so it must be in the constructor of the superclass which is Activity. Unfortunately the debugger doesn't give any detailed information on what class it is trying to cast. Here is the stacktrace:
Thread [<1> main] (Suspended (exception RuntimeException))
ActivityThread$PackageInfo.makeApplication(boolean, Instrumentation) line: 649
ActivityThread.handleBindApplication(ActivityThread$AppBindData) line: 4232
ActivityThread.access$3000(ActivityThread, ActivityThread$AppBindData) line: 125
ActivityThread$H.handleMessage(Message) line: 2071
ActivityThread$H(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 4627

ZygoteInit$MethodAndArgsCaller.run() line: 868
ZygoteInit.main(String[]) line: 626
NativeStart.main(String[]) line: not available [native method]
And when I look into this runtimeexception I get:
detailMessage "Unable to instantiate application com.test.MyApp: java.lang.ClassCastException: com.test.MyApp" (id=830067694464)
The only code is:
package com.test;

public class MyApp extends Activity {

Android :: Speed Up Launch Of Activity Containing Mapview And Extends MapviewActivity?
Nov 12, 2010I have an app which contains an activity which is a MapviewActivity and is mostly a mapview.
However I have noticed that the start up time of the activity is really slow and causes a lag from the moment the button is pressed to go in to the map activity. I feel this creates a bad user experience and would like to avoid this.
I have already set the background of the map activity to @null as suggested by one of the UI improvement articles on googles developer page. Which I fell does not do the trick.
Is there a way to improve this? I would not like the main home screen to get stuck on the launch of the activity, even a transfer to the map activity and then loading the mapview would be better.

Android :: Use Custom Color For Each Textview In Listview That Extends SimpleAdapter In Droid?
May 31, 2010I have a listview with custom rows and that extends SimpleAdapter.
Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation.
Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row.
To put it as simple:
each listview item has some custom colors the value of which comes from the hidden field.
I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it).
Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other?

I would've tried to send a screenshot for this query if I could, but i'll try and explain.

Is this possible, if so how?

Android :: Getting The TabActivity To Work?
Mar 26, 2010I'm having some difficulties getting the TabActivity to work.
Here's the implementation of the class:
CODE:..........
The problem is that I call this class from my main activity (which is a MapActivity if it matters) and when I do the TabActivity doesn't show. It registers the click on the option menu and it even starts the intent but the screen doesn't change..it just stays on the main activity and i see in the logs that the main activity gets resumed.
I call it like this:
CODE:...............
Like I said...there are no errors (the classes called from the tabs exist of course), just no actions. I put some log commands into the onCreate function in the tabactivity (as you see) and they all get written into the log...I have no idea what I'm doing wrong here.

View 1 Replies View RelatedAndroid :: TabActivity - Refreshing ?
Aug 18, 2009I have a TabActivity based class which has 3 tabs. All are ListActivities (but that's not important for this problem)
I'm updating the TabHost's TabSpec's to change the text on the tabs. This works fine and the ListActivities display correctly.
Iater on the execution flow I need to update the Text on the tabs from "Current Text" to "Current Text (3)", for example. I update the TabSpec.setIndicator() with the new text, and attempt to call invalidate() on the TabWidget (and all it's children). But the tab text refuses to update!
