Android setdrawable from another class

Here's my code. I am trying to set background of a linear layout. But this xml (rowback) is not my main activity content, so gives errors. how can I set some XML from the class which doesn't have that XML in its content?
setContentView(R.layout.activity_quick_search_products);
...
rowb = (LinearLayout)findViewById(R.id.rowback);
...
final Drawable d = getResources().getDrawable(R.drawable.denemebut3);
d.setAlpha(100);
rowb.setBackgroundDrawable(d);

If R.id.rowback doesn't belong to your main activity xml resource, then you should inflate that resource manually using:
LinearLayout rowb = (LinearLayout) getLayoutInflater().inflate(XML file that contains R.id.rowback, null);
then you can safely do
rowb.setBackgroundDrawable(d);
As an extra, if you have nested elements in rowback then you can invoke:
rowb.findViewById(R.id.Something) safely.
Or if your class is not exteding from any Activity, you can always receive a Context object in its constructor, and then use
LayoutInflater.from(context)
to get a LayoutInflater object so you can inflate any XML resource you need that is not actually in your main content.
Hope this clarifies...

Java Build Path and the cleaning up of unwanted debris

In the course of my endevours I added two versions of androidplot to my project. I realised it is causing conflict so I tried removing both to start again and I am now getting

Can anyone tell me how to clean this up please?

I realised what the issue was here, I still had a androidplot element in my layout, so in fact the project wasn't fully cleaned of the attempt
Thanks

Issue with Google Maps Android Api v2

I have been trying to implement a sample application in order to study the working of Google maps API. I have been struck with the configuration itself. I can't seem to run the application.
Here's my code at Github :-

Would you please help? Thanks in advance.

It looks like it's not finding the Google Maps classes at runtime. Are you running this on a device or an emulator because you can't use Google Maps v2 on an emulator at this time.
If you are running on a device then make sure you have Google Play Services installed. It contains the runtime for Google Maps v2.

Solved my Problem. The issue occurred because even though I i referenced the google play library, The reference is not considered by eclipse and it was shown by a cross mark. I have resolved that with the help of the following stackoverflow post:-
In eclipse, unable to reference an android library project in another android project

Android Inflate Exception occurred

What I have to do for this memory problem ?

Yeah it feels like a memory issues, try releasing some bitmaps prior to accessing that
particular View.
I suggest to check out this video http://dubroy.com/blog/google-io-memory-management-for-android-apps/ which talks about Android memory management.
One thing worth mentioning is that prior to honeycomb, bitmaps were allocated in the native
heap, so watch out for it when profiling memory.
If you're on a device which if Honeycomb or newer, the bitmaps are allocated in the managed
heap.

Create a view by Java code

I used the following code to add a view in a layout
LinearLayout linearLayout_row1_recent_released = (LinearLayout)findViewById(R.id.linearLayout);
View myview = findViewById(R.layout.row);
Button button = myview.findViewById(R.id.mybutton);
linearLayout_row1_recent_released.removeAllViews();
linearLayout_row1_recent_released.addView(myview,LinearLayout.LayoutParams.FILL_PARENT);
Using row.xml i've tried to get a view.
What i get is a FATAL EXCEPTION.

Is there any other good way to add views dynamically to a linear layout? What have I done wrong here ?

I am guessing that the view R.layout.row is defined in a separate XML file, and you want to include it here. If that is the case,
findViewById(R.layout.row)
will not work because R.layout.row is not visible in the current activity.
You need to use layout inflater to inflate the view, and then you can add it to the linear layout. The way to do this is
LayoutInflaterinflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View myView = inflater.inflate(R.layout.row, null);
linearLayout_row1_recent_released.addView(myview,
new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT) );

Your call to addView is wrong.
You are calling addView(View, int), but it should be: addView(View, LayoutParams):
linearLayout_row1_recent_released.addView(myview,
new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT) );
