Android :: Change LinearLayout Layout At Runtime

Aug 25, 2010

I want the ability to re-arrange Views in a LinearLayout, without specifying specific pixel locations, at runtime. for my proof of concept, I have a layout with 2 TextViews, one red, and one black. The red TextView is on the left. I want onClick to set it to be on the right, without adjusting margins, as if I'd re-written the XML of the layout, with the red TextView second.

Android :: LinearLayout - Use Another API's Layout Manager?

Nov 7, 2010

On the emulator, I see the custom SurfaceView _map Object take up the whole screen, except for the EditText text-box at the bottom, right where it should be. When I run the same code, same everything, on my Motorola Droid, there is no EditText to be seen anywhere. I figure that I am missing something with the LinearLayout implementation I have. Until now, I've gotten off easy on learning how to use another API's layout manager.

Here's the code:.......................

Dec 21, 2009

I am currently working on a project which requires me to use an XML document to render a form on an Android device. The form must be fetched and displayed at run-time.

Android :: Any Set Style Method At Runtime In Layout File?

Feb 1, 2009

I created my style in styles.xml, lets say MyStyle. I can use it in any layout file by style="@style/MyStyle". Also my generated R class have R.style.MyStyle, my question is if I can use it at runtime to "setStyle" - unfortunately View doesn't have such a method. If not what is R.style.MyStyle used for? (I already know that custom themes IDs are also in R.style and can be used to setTheme, but MyStyle is not a theme).

Android :: Choose Button Layout To Include At Runtime

Dec 17, 2009

I have a complex dialog-layout that has to be customized for small screens to decrease its height on such devices. This can easily be achieved by decreasing the height of several single Buttons and Textfields in the layout, each by a small amount. Of course much of the layout still stays the same, so I figured I could use the <include/>-tag. This was the idea:

/res/layout/dialog_layout.xml ==> includes "@layout/include_button_layout"
/res/layout/include_button_layout.xml /res/layout-small/include_button_layout.xml

I figured that android would choose which button-layout to include at runtime. I couldn't get it to run, so I guess I was wrong. And if so, can anyone confirm whether this is the way to do it?

/res/layout/dialog_layout.xml ==> includes "@layout/include_above_buttons"
==> includes "@layout/include_button_layout_default"
==> includes "@layout/include_below_buttons"
/res/layout/include_above_buttons.xml
/res/layout/include_below_buttons.xml
/res/layout/include_button_layout_default.xml
/res/layout/include_button_layout_small.xml
/res/layout-small/dialog_layout.xml
==> includes "@layout/include_above_buttons"
==> includes "@layout/include_button_layout_small"
==> includes "@layout/include_below_buttons"

Android :: Create A Layout - Multiple Scrollable ExpandableListViews In A Vertical Linearlayout?

May 7, 2010

Any insights/pointers regarding creating a layout like this. I have wasted quite a bit of time on this. I want to create a vertical linearlayout which has multiple ExpandableListViews separated by TextViews.

CODE:.........................

I tried the following approaches but each of them has one shortcoming or the other:

1. Add TextView and ExpandableListViews to a linearlayout. The problem with this approach is that LinearLayout by default is unscrollable.

Adding the LinearLayout to a ScrollableView creates even more issues because ListViews handle their own scrolling behavior.

2. I tried using a single ExpandableListView to model the above layout but the problem is that setGroupIndicator applies to the entire ExpandableListView, not a specific group.

Android :: Runtime Language Change Support

Mar 8, 2010

I am developing an Android App which communicated with a server. User can select a language of his choice at startup or during the App execution lifetime. After selecting the language, the corresponding XML file is downloaded from server according to language which will map the "Values" of Application strings according to that language. Can I do something like replacing the default Strings.xml which contains English names(Say by default) to the language selected by user. Better will be adding an XML file per language and referring it runtime directly.

Android :: Prevent Orientation Change At Runtime

Apr 15, 2010

Well, preventing an orientation change is easy. But what about doing it at run time.

Say, I have an activity which supports orientation change in normal situations. It has say three Edit Texts.

There's also a button, which when clicked would do some processing in a thread while showing a ProgressDialog which is not cancellable.

Ok, so till the user hits the Button, I want the activity to be able to adapt the orientation changes. I have two layouts files for each orientation with different layout schemes.

What I want is this. Once the user clicks on the button, and the ProgressDialog is showing, I don't want the activity now to be re- created again when the orientation changes. So, before showing the ProgressDialog, is there any way to tell the Activity not to handle Orientation change?

Also, once the process is complete, and the ProgressDialog is removed, I want the Activity again to be able to handle orientation changes.

Android : Change The Height Of A Webview On Runtime

Feb 26, 2010

I have a webview and a table containing 4 buttons. I have set the height of the webview to 400px, so that the buttons are displayed at the bottom of the screen, in portrait mode. My problem is, when changed to landscape mode the buttons are not visible. So I need to change the height of the webview on runtime, when orientation is changed. Do anybody know how to achieve this? I am able to capture the orientation change, using 'onConfigurationChanged' function.

Android :: TextView Inside LinearLayout Stretches The LinearLayout

Aug 21, 2010

If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.

Here is the code:..............

Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):

So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):

As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.

Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg

Android :: Change Background Image Of Dialog Or View In Runtime?

Aug 9, 2010

I have a card game I created in android and it is possible to show the scores at any given time by clicking a menu option. I would like that scores dialog to show a different background image when it's loaded depending on factors like who's leading, etc. In my constructor, I have the following relevant code:

public ScoresDialog(Context context) {
super(context);

this.setTitle(R.string.scoresDialogHeading);
setContentView(R.layout.scores_view);
...
}

I have tried getting that view to change it in the showDialog method i wrote like so: findViewById(R.layout.scores_view).setBackgroundColor(Color.BLUE); However, I got a NPE... I tried moving this statement to the onStart method, thinking that the view is not yet initialized but got the same error... Any thoughts on what the right way to do something like that is?

Android :: Possible To Load A Layout XML At Runtime And Load Into Activity?

Sep 4, 2010

Is it possible to load a layout XML at runtime and load into activity?

In my app, I have various types of data like Person, Company, City, etc; The requirement is to dynamically load the layout, find views by tags (property names like Person.name, Person.address) and then fill in data. For example, if user has selected an object of type Company, we want to load a company.xml layout, inflate it and then associate various properties (company name, company slogan, city, address, revenue) to tagged views. One possibility I see here is - each view in the layout will be associated with property-name as tag and then appropriate data will be loaded in appropriate views.

What should be the best design you would recommend?

Android : Change Android Theme At Runtime?

Dec 3, 2009

I am now working on changing android theme style at runtime,when the user select a theme resource,not only the current application,but also all the applications installed on the phone should be changed.For example,just like you change the system language in setting activity,then all the applications' language changed.I just can not figure out how android framework achieves this,anybody knows something about this?

While I tried to use PackageManager,just like this:

PackageManager manager = getPackageManager();
List<ApplicationInfo> apps = manager
.getInstalledApplications(PackageManager.GET_META_DATA);

for (ApplicationInfo app : apps) {
app.theme=android.R.style.Theme_Light_NoTitleBar_Fullscreen;}

It won't work.Does the attribure "theme" in ApplicationInfo read-only?

Android :: Runtime Error Using Exported - Signed Apk But No Runtime Error Using Eclipse IDE

Mar 2, 2009

1) I am developing my app in Eclipse 3.4.1 with Android (ver 1.1_r1) plugin. My app compiles and executes without errors when using the Eclipse IDE.

However, when I export my app (unsigned) using Eclipse (via {select project} >right-click>Android tools>export unsigned application package), sign it, and try to run it on the Emulator, it throws a runtime error when I try to update my sqlite database, at which time the specific error created is: SQLite error#14, unable to open database. It is able to read from the database without problems. (I have also verified that the database is: open, is not readonly, is not locked by another thread, is not in the middle of a transaction.)

I have limited experience, but this seems more like a "system" problem given that the app works OK in Eclipse IDE but then fails as an exported/signed apk. Some googling of SQLite resources revealed a similar error on a non-Android platform which was fixed by: "Set your permissions correctly on /var/tmp, or whatever directory you are using to hold temporary files".

Does Android have temporary files, and if so how does it handle permissions on temporary files? Is there a way to check or set these permissions to see if this fixes my problem here?

2) Not sure if it is related, but after I have run the exported/signed app which causes the runtime error, if I reboot the Emulator, and try to run the program using the Eclipse IDE , the program fails with the same exact error. PLUS I also noticed the following error message while the program is installing/running: 03-01 22:22:29.282: ERROR/PackageManager(53): Package com.northwestradiology has mismatched uid: 0 on disk, 10019 in settings; read messages:

I can restore the Eclipse version of my program to be able to execute without runtime errors by utilizing the -wipe-data option for the emulator. But note that if I run my signed APK using an emulator created with the -wipe-data option, it still throws the runtime error listed above...
