1 How do I set background image to my application?

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="5dip"
    android:background="@drawable/icon">
</RelativeLayout>

It's important to use RelativeLayout instead of LinearLayout.

Or use the following to set background programmatically:

layout = new AbsoluteLayout(this);
Bitmap bitmap = BitmapFactory.decodeResource(this.getResources(), R.drawable.abc_bg_img);
BitmapDrawable background = new BitmapDrawable(bitmap);
layout.setBackgroundDrawable(background);
ImageView imageView = new ImageView(this);
imageView.setImageResource(R.drawable.img_name);
imageView.setAdjustViewBounds(true);
imageView.setLayoutParams(new AbsoluteLayout.LayoutParams(100, 100, 100, 100));
layout.addView(imageView);
this.setContentView(layout);

2 How do I change location of a View item?

Use setLeftAndRight() and setTopAndBottom(), remember to use view.invalidate() to trigger redraw.
