Android : Layout - Content Extends Over The Visible Area
Dec 27, 2009
Currently 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.

I am experimenting with using a WebView to display Flash content inside my activity. Everything is working pretty well, but when the user hits the home key to put the activity into the background, the Flash content keeps running (sound keeps playing, etc)
I have noticed that both the stock Android browser and Dolphin Browser seem to avoid this problem, and properly pause the Flash content when the browsing activity is put into the background.
Ideally I would like a solution that kills the WebView completely if the activity is finishing, but pauses it otherwise (basically copying the default behavior of the browser)
Here is a simple test I put together that loads a game on Kongregate which has some background music:
CODE:..............
I took a look at the latest source for the stock browser, and it seems to be doing something similar (calling pauseTimers/resumeTimers), although I fear the code I have been looking at is out of date, because it is calling functions that don't seem to exist anymore.
I did verify that the call to pauseTimers is working by testing with a simple JavaScript setInterval which updates a counter. Is there something else obvious that I should be trying in regard to Window or View management?
The documentation for the mobile Flash player says:
Flash Player will also automatically pause SWF playback it is not in view or the foreground application, for example when a call is received or alarm goes off, to reduce CPU utilization, battery usage and memory usage.
This seems to be working perfectly in both the stock browser and Dolphin Browser, but not in my app. Any ideas/solutions would be greatly appreciated!
Update: Here is the function we ended up adding to our activity to get this to work. We call it with "onPause" in the activity's onPause function and "onResume" in the activity's onResume function:

I have a layout that is three linear layouts. The top has some icons and the middle has a tabhost. Each tabhost has a list inside it. The bottom linearlayout has two buttons that should stay at the bottom on the screen at all times. The problem is when a list in the tabhost gets too long, it displays over the buttons. I tried to find some way to get the buttons to bedisplayed over the list but have failed so far.

The xml files that contains the Activity layouts can be rendered by Eclipse.
How do I get that Eclipse screen area to have vertical orientation, not horizontal (inside Eclipse - it correctly shows as vertical in the emulator)?

How do I go about creating the following layout in Android?
I want a "header", that is, a header that stays the same at all times. The only thing that should change is the area below the header.
Think of it as a webpage, where the content-area is where its all happening =)
+--------------------+
| H E A D E R |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
Sure, its easy enough to create a LinearLayot, add a View on the top and then another view below that - tada! But what Im after is how you "set up" or design the project so its easy to just change whats in the Content.
What I really would like is to be able to "swipe" (see here) the area and then just "roll in" a new View/thing in the Content-area, but keep the same header.

I have a layout which contains a TextView.
The content of the TextView might change on runtime. (discussed on a different issue here: http://stackoverflow.com/questions/3683727/layout-with-dynamic-position )
I can position the layout by drag&drop. If the size of the layout doesn't change, the position stays, but as soon as the size of the layout changes (because more text inside the TextView) the position is reseted.
I use the layout(left, top, right, bottom) to position the layout.
Now I don't know where I should add my layout() call to make sure it stays at the right position...
Here is my class

I'm using data to build elements of a ViewGroup. The ViewGroup are LinearLayouts, except the leaves, which are TextViews. Because Data draws the hierarchy, I inflate the LinearLayouts and TextViews from individual XML files programatically on the fly.
My Problem:
When I create a LinearLayout with the attribute wrap_content, then inflate a TextView or other LinearLayout into it, I can't get the parents (or enough of them, anyway) to redraw, respecting the new view. These LinearLayouts always seem to come out at 0 size, because when they are first created (before their children are inflated), they wrap around nothing. I've tried calling some stock methods of ViewGroup but nothing seems to work.

When i ran my old application in 1.6 i noticed that the progress bar was not showing up on the screen.When i analyzed it further i found the issue.The progress bar is getting activated but its not visible since my background color is also white.When i changed the background color i was able to see the progress bar.Is there no other way to make the progress bar visible other than changing the background color..Shouldn't the progress bar be visible under all background colors??

I 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.)

I'd like to know: Is it possible to extend Android APIs with other .jar file?
If it's possible, how can I extend the APIs?

This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

I 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
Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
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;
import android.app.Activity;
public class MyApp extends Activity {

I 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.

I created a list view in an activity and the list shows some fields.When we click a list item a custom dialog should pop up and the user can enter some new value to this field.The custom dialog contains one edit text and two buttons ok and cancel.It is working fine.But when my list is more that means if it exceeds screen size it is showing scroll.But when we select bottom items which we can select using scroll the dialog is appearing in normal fashion.But after entering new value if i am trying to save the application is getting crashed.
