Remove extra space around GridView programmatically

Question

I am trying to make a GridView programmatically in my java class and it all works fine. The problem is the auto-generated 5 pixel padding around the GridView. In the xml I manage to remove it using:

android:listSelector="@null"

But I do not manage to do anything similar in java. I have tried some workarounds like making the GridView 10 pixels larger then the actual screen with no luck.

Does anyone have any code for this?

Edit:

The answer by me does not solve the problem. There is still a bounty going. Here is my GridView code:

    GridView gridView = new GridView(this);
    gridView.setNumColumns(someInt);
    gridView.setAdapter (new MyCustomAdapter(this));
    gridView.setLayoutParams(new GridView.LayoutParams(
            customValue,
            LayoutParams.FILL_PARENT,
            Gravity.CENTER_HORIZONTAL)
    );

Answer 1

• One way to ensure the padding appears same on screens with different density is by converting it to DIP units.

  int padding = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, -5, 
                                      getResources().getDisplayMetrics());
  

• Other thing you can try is to define a null drawable in xml..

  <?xml version="1.0" encoding="utf-8"?>
  <resources>
      <drawable name="null_drawable">@null</drawable>
      ...
  </resources>
  

  Then call setSelector(R.drawable.null_drawable);

Update:

• Define your GridView in its own xml and inflate it.

  layout/mygrid.xml

  <?xml version="1.0" encoding="utf-8"?>
  <GridView 
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:listSelector="@null"/>
  

  In java,

  GridView gridView = (GridView)inflater.inflate(R.layout.mygrid, null);
  gridView.setLayoutParams(new GridView.LayoutParams(customValue, 
                          LayoutParams.FILL_PARENT));
  gridView.setNumColumns(someInt);
  gridView.setAdapter (new MyCustomAdapter(this));
  

Answer 2

Solved it sort of by:

    gridView.setPadding(-5, 0, -5, 0);

But you need different padding for different screens. But it is not a complete solution. Functional modifications of this code will be accepted.
