Body
Take a look at <blockquote> public static Bitmap <a href="http://developer.android.com/reference/android/graphics/Bitmap.html#createBitmap%28android.graphics.Bitmap,%20int,%20int,%20int,%20int,%20android.graphics.Matrix,%20boolean%29" rel="nofollow">createBitmap</a> (Bitmap source, int x, int y, int width, int height, Matrix m, boolean filter) </blockquote> Since: API Level 1 Returns an immutable bitmap from subset of the source bitmap, transformed by the optional matrix. It is initialized with the same density as the original bitmap. Parameters <pre><code> source The bitmap we are subsetting x The x coordinate of the first pixel in source y The y coordinate of the first pixel in source width The number of pixels in each row height The number of rows m Optional matrix to be applied to the pixels filter true if the source should be filtered. Only applies if the matrix contains more than just translation. </code></pre> Returns <pre><code>A bitmap that represents the specified subset of source </code></pre> <hr> You can also <a href="http://www.coderzheaven.com/2011/03/15/crop-an-image-in-android/" rel="nofollow">crop specific portion of image-in-android</a> and then use createBitmap to format the new cropped image. <hr> <h2>An example of using createBitmap:</h2> <pre><code>public class bitmaptest extends Activity { @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); LinearLayout linLayout = new LinearLayout(this); // load the origial BitMap (500 x 500 px) Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher); int width = bitmapOrg.getWidth(); int height = bitmapOrg.getHeight(); int newWidth = 200; int newHeight = 200; // calculate the scale - in this case = 0.4f float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // createa matrix for the manipulation Matrix matrix = new Matrix(); // resize the bit map matrix.postScale(scaleWidth, scaleHeight); // rotate the Bitmap matrix.postRotate(45); // recreate the new Bitmap Bitmap resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0, width, height, matrix, true); // make a Drawable from Bitmap to allow to set the BitMap // to the ImageView, ImageButton or what ever BitmapDrawable bmd = new BitmapDrawable(resizedBitmap); ImageView imageView = new ImageView(this); // set the Drawable on the ImageView imageView.setImageDrawable(bmd); // center the Image imageView.setScaleType(ScaleType.CENTER); // add ImageView to the Layout linLayout.addView(imageView, new LinearLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT ) ); // set LinearLayout as ContentView setContentView(linLayout); } } </code></pre>

1. COThanks for the details. But I went with changing rect in ondraw() which really worked well.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
