Body
<p>Improving on the solution above by Timmmm to add some extra scaling at the end to ensure that the image fits within the bounds:</p> <pre><code>public static Bitmap loadBitmap(String path, int orientation, final int targetWidth, final int targetHeight) { Bitmap bitmap = null; try { // First decode with inJustDecodeBounds=true to check dimensions final BitmapFactory.Options options = new BitmapFactory.Options(); options.inJustDecodeBounds = true; BitmapFactory.decodeFile(path, options); // Adjust extents int sourceWidth, sourceHeight; if (orientation == 90 || orientation == 270) { sourceWidth = options.outHeight; sourceHeight = options.outWidth; } else { sourceWidth = options.outWidth; sourceHeight = options.outHeight; } // Calculate the maximum required scaling ratio if required and load the bitmap if (sourceWidth > targetWidth || sourceHeight > targetHeight) { float widthRatio = (float)sourceWidth / (float)targetWidth; float heightRatio = (float)sourceHeight / (float)targetHeight; float maxRatio = Math.max(widthRatio, heightRatio); options.inJustDecodeBounds = false; options.inSampleSize = (int)maxRatio; bitmap = BitmapFactory.decodeFile(path, options); } else { bitmap = BitmapFactory.decodeFile(path); } // Rotate the bitmap if required if (orientation > 0) { Matrix matrix = new Matrix(); matrix.postRotate(orientation); bitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true); } // Re-scale the bitmap if necessary sourceWidth = bitmap.getWidth(); sourceHeight = bitmap.getHeight(); if (sourceWidth != targetWidth || sourceHeight != targetHeight) { float widthRatio = (float)sourceWidth / (float)targetWidth; float heightRatio = (float)sourceHeight / (float)targetHeight; float maxRatio = Math.max(widthRatio, heightRatio); sourceWidth = (int)((float)sourceWidth / maxRatio); sourceHeight = (int)((float)sourceHeight / maxRatio); bitmap = Bitmap.createScaledBitmap(bitmap, sourceWidth, sourceHeight, true); } } catch (Exception e) { } return bitmap; } </code></pre>

Guidance

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.
