    <p>I implemented FixedAspectRatioFrameLayout, so I can reuse it and have any hosted view be with fixed aspect ratio:</p> <pre><code>public class FixedAspectRatioFrameLayout extends FrameLayout { private int mAspectRatioWidth; private int mAspectRatioHeight; public FixedAspectRatioFrameLayout(Context context) { super(context); } public FixedAspectRatioFrameLayout(Context context, AttributeSet attrs) { super(context, attrs); init(context, attrs); } public FixedAspectRatioFrameLayout(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); init(context, attrs); } private void init(Context context, AttributeSet attrs) { TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.FixedAspectRatioFrameLayout); mAspectRatioWidth = a.getInt(R.styleable.FixedAspectRatioFrameLayout_aspectRatioWidth, 4); mAspectRatioHeight = a.getInt(R.styleable.FixedAspectRatioFrameLayout_aspectRatioHeight, 3); a.recycle(); } // **overrides** @Override protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec) { int originalWidth = MeasureSpec.getSize(widthMeasureSpec); int originalHeight = MeasureSpec.getSize(heightMeasureSpec); int calculatedHeight = originalWidth * mAspectRatioHeight / mAspectRatioWidth; int finalWidth, finalHeight; if (calculatedHeight &gt; originalHeight) { finalWidth = originalHeight * mAspectRatioWidth / mAspectRatioHeight; finalHeight = originalHeight; } else { finalWidth = originalWidth; finalHeight = calculatedHeight; } super.onMeasure( MeasureSpec.makeMeasureSpec(finalWidth, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(finalHeight, MeasureSpec.EXACTLY)); } } </code></pre>

    2. COI just implemented something along these lines, based on `PreviewFrameLayout` from the Camera AOSP app. However, I am noticing that gravity no longer seems to be honored -- in cases where the height is constrained, all the extra whitespace seems to be at the bottom even with `Gravity.CENTER` or `Gravity.BOTTOM`, for example. Have you seen this? If so, did you happen to come up with a solution? Thanks!

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.
