Body
<p>I scrapped the variant of the 2 TextViews since it looked weird (edges weren't smooth and, since I have a lot of such elements on the screen it was really lagging the scrolling). What I did, was a crazy hack that does the animation with the use of a Thread and setTextColor (that also forces redraw of a textview).</p> <p>Since I needed only 2 color changes (from red to white, and from green to white) I hardcoded the values and all of the transition colors between them. So here's how it looks:</p> <pre><code>public class BlinkingTextView extends TextView { public BlinkingTextView(Context context, AttributeSet attrs) { super(context, attrs); } public void animateBlink(final boolean red) { if (animator != null) { animator.drop(); } animator = new Animator(this, red); animator.start(); } public void clearBlinkAnimation() { if (animator != null) { animator.drop(); } } private Animator animator; private final static class Animator extends Thread { public Animator(final TextView textView, final boolean red) { this.textView = textView; if (red) { SET_TO_USE = RED; } else { SET_TO_USE = GREEN; } } private TextView textView; private final int[] SET_TO_USE; private final static int[] RED = { -2142396, -2008754, -1874854, -1740697, -1540490, -1405563, -1205099, -1004634, -804170, -669243, -469036, -334879, -200979, -67337, -1 }; private final static int[] GREEN = { -6959821, -6565826, -6106293, -5646758, -5055894, -4530309, -3939444, -3283042, -2692177, -2166592, -1575728, -1116193, -656660, -262665, -1 }; private boolean stop; @Override public void run() { int i = 0; while (i < 15) { if (stop) break; final int color = SET_TO_USE[i]; if (stop) break; textView.post(new Runnable() { @Override public void run() { if (!stop) { textView.setTextColor(color); } } }); if (stop) break; i++; if (stop) break; try { Thread.sleep(66); } catch (InterruptedException e) {} if (stop) break; } } public void drop() { stop = true; } } } </code></pre>

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.
