Android :: Change Nested Layout's Child View Group's Width In Java Code?

Oct 6, 2010

I have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this

ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);

I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.

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?
