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 :: Bottom Of One LinearLayout Being Hidden By Other LinearLayout

May 25, 2010

I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.

anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.

screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

Android :: Using Generics In Java Code

Sep 28, 2010

I need to de-serialise a file into an object of a given type. Basically the method will do this:

FileInputStream fis = new FileInputStream(filename);
ObjectInputStream in = new ObjectInputStream(fis);
MyClass newObject = (MyClass)in.readObject();
in.close();
return newObject;


I would like this method to be generic, therefore I can tell it what type I want to in.readObject() to cast its output into, and return it. Hope this makes sense...then again, I probably didn't understand generics properly and this is not actually possible, or advisable.

Android :: Get Reference To TabWidget In Java Code

Mar 9, 2009

In my layout xml, I have: <TabHost android:id="@+id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">

<TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/>

</TabHost>

My question is how can I get a reference to TabWidget object. I tried this: mTabWidget = (TabWidget) findViewById(com.android.internal.R.id.tabs); but this won't compile since 'com.android.internal.R is not visible. And then I try change the id to android:id="@+id/tabs" but I get a run time error saying: "Your TabHost must have a TabWidget whose id attribute is 'android.R.id.tabs'"

Android :: Correct Way To Specify Dimensions In DIP From Java Code?

Nov 24, 2010

I found that it is possible to set dimensions of my interface elements in XML layouts using DIPs as in following fragment : "android:layout_width="10dip" But all Java interface takes integer as arguments and there is no way to specify dimensions in DIPs. What is the correct way to calculate this? I figured that I have to use property density of DisplayMetrics class but is this a correct way ? May I rely on that formula:
pixels * DisplayMetrics.density = dip

Android :: Eclipse Reading Code As Java

Nov 23, 2010

I just inherited a project at my workplace and I am having trouble having Eclipse act as an Adroid editor rather than a Java editor. Pretty much everything is under lined and I can't seem to find a way to change how it is interpreted. I have downloaded all of the Android SDK's and the Eclipse Plugin. I can create Android projects and write the code just fine, but everything is still underlining. I must be missing something simple. Any suggestions, something I missed or didn't download?

Android :: Java Code Formatter Profile For Eclipse IDE

Mar 19, 2010

Did anyone create the Java Code Formatter Profile for Eclipse IDE that conforms to the Android Code Style Rules? Android Code Style Guide defines "Android Code Style Rules".To conform to these rules one have to change quite a number of settings of the Java Code Formatter
(Window->Preferences->Java->Code Style->Formatter) default profile (in Eclipse IDE).

Did anyone manage to configure the formatter to follow the "Android Code Style Rules" already?
If yes, please export the Formatter profile and publish to be used by community. I've tried to do this myself but I've found that there are too many formatter options available, and most of them are not mentioned in the Code Style Guide.

Android :: Generate Java Source Code In Eclipse?

Jun 2, 2010

Does anyone know what approach one can take to automatically generate Java source code, from for example an xml or json file, in eclipse? One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources. Every time a resource file is saved in Eclipse R class is automatically regenerated.

UPDATE: Example:
In the text (xml or json file) I have the following:
<tags>
<tag id="ALPHA">
<description>The first alpha tag.</description>
<value>231232</value> </tag> <tag id="BETA">
<description>This is the beta tag.</description>
<value>231232</value> </tag>

Then in my generated java class, say R I would have something like:
R.tags.ids.ALPHA //refers to an enum value for example
R.tags.values.ALPHA //refers to final int with avlue 231232
R.tags.descriptions.ALPHA //refers to the String with description

Android :: Java.lang.StackOverflowError When Run Code On Sdk1_1r1

Sep 17, 2009

I am using custom listadapter for ListActivity, but half adapter is getting built and then throws "java.lang.StackOverflowError". When I ran the same code on sdk1_1r1 it works perfect. When do i try to run on sdk1_5r3, gives this error. Generally java.lang.StackOverflowError when happens if the some function caught in infinite recursion, but if this is case then why does it working on sdk1.1r1 perfectly. I tested the appl on sdk1_5r3 both emulators default AVD(96 RAM) and custom AVD(523 RAM). For all try it gives the same error.
