newPost =new Button(BlogsList.this); newPost.setText("Add Entry To Blog"); newPost.setPadding(10, 10, 10, 10); newPost.setLayoutParams(new LayoutParams (LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT)); newPost.setOnClickListener(new NewPost(b.getName (),b.getBlogId())); l22.addView(newPost);
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.

View 3 Replies View RelatedIn 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'"

View 6 Replies View RelatedI 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.

pixels * DisplayMetrics.density = dip

View 3 Replies View RelatedI 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?

View 3 Replies View RelatedDid 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.
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
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.
