WebSphere Role Override

The other day I was having issues with my WebSphere security role definitions. It didn't matter what I did or how I updated the WebSphere role mappings, it wouldn't let my authorized user access some protected resources. I tried setting the special mapping to ALl_AUTHENTICATED, I mapped 3 different groups that I knew the user was in, and then I even added the user to the role. No luck. Turns out the problem was fixed by looking at my ibm-applicatoin-bnd.xml file. If that file even references the security-role it will fail and no overriding on the websphere admin console will work. Removing that reference and all my mapping worked perfectly.

Android trick to set a TextView bold

that's it!

Android Setting TextColor

You can't do something like this:

inststatus.setTextColor(R.color.white);

instead do:

inststatus.setTextColor(getResources().getColor(R.color.white);

Java Dynamically adding Android Views android:Layout_toRightOf

I found this post really useful today:
http://stackoverflow.com/questions/2305395/laying-out-views-in-relativelayout-programmatically

ex.

RelativeLayout layout = new RelativeLayout(this);
TextView tv1 = new TextView(this);
tv1.setText("A");
tv1.setId(23);

TextView tv2 = new TextView(this);
tv2.setText("B");
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.FILL_PARENT);
lp.addRule(RelativeLayout.RIGHT_OF, tv1.getId());

layout.addView(tv1);       
layout.addView(tv2, lp);

******
you need to provide id's to your child views: tv1.setId(1); tv2.setId(2); Parent views do not automatically assign child views an Id, and the default value for an Id is NO_ID. Id's don't have to be unique in a view hiearchy - so 1, 2, 3, etc are all fine values to use - and you must use them for relative anchoring to work in RelativeLayout

Android screen capture

I found out how to use Eclipse to grab a screen capture of my android device. REALLY cool. No market app necessary.

1. Connect your phone to your computer
2. Open Eclipse
3. Click on the DDMS Perspective
4. Look at the Devices view
5. Click on your phone
6. Use the Menu Icon to Select > Screen Capture.
   
   
   
7. You'll see something like this:
   
   
   
   
8. Save your screen capture

Android custom buttons

http://stackoverflow.com/questions/1521640/standard-android-button-with-a-different-color

Put something like the following code in a file named custom_button.xml and then set background="@drawable/custom_button" in your button view:

xml version="1.0" encoding="utf-8"?>



  xmlns:android="http://schemas.android.com/apk/res/android">



   android:state_pressed="true" >

      

          

              android:startColor="@color/yellow1"

              android:endColor="@color/yellow2"

              android:angle="270" />

          

              android:width="3dp"

              color="@color/grey05" />

          

              android:radius="3dp" />

          

              android:left="10dp"

              android:right="10dp"

              android:bottom="10dp" />

      

  



       

      

          

              android:endColor="@color/blue2"

              android:startColor="@color/blue25"

              android:radius="3dp" />

          

              android:left="10dp"

              android:top="10dp"

              android:right="10dp"

              android:bottom="10dp" />

      

  

How to Add a repeating background graphic on an Android Application

This took me a little to find the right resource to make this happen. So here it is:

http://android-developers.blogspot.com/2009/03/window-backgrounds-ui-speed.html

The author shows how to add a style for a repeating background towards the end. The style isn't picked up immediately using the Eclipse xml editor but once the application starts it's there.
