    <p>I have a gradient drawable defined in xml that I use it as a background, like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:bottom="4dp"&gt; &lt;shape&gt; &lt;gradient android:startColor="@color/blue" android:endColor="@color/dark_blue" android:angle="270" /&gt; &lt;/shape&gt; &lt;/item&gt; &lt;item android:top="98dp"&gt; &lt;shape&gt; &lt;gradient android:startColor="@color/black" android:endColor="@color/transparent_black" android:angle="270" /&gt; &lt;/shape&gt; &lt;/item&gt; &lt;/layer-list&gt; </code></pre> <p>I need to implement this programmatically. I have tried to use a GradientDrawable as follows (this method is implemented on a custom view):</p> <pre><code>int[] colors1 = {getResources().getColor(R.color.black), getResources().getColor(R.color.trasparent_black)}; GradientDrawable shadow = new GradientDrawable(Orientation.TOP_BOTTOM, colors1); shadow.setBounds(0,98, 0, 0); int[] colors = new int[2]; colors[0] = getResources().getColor(R.color.blue); colors[1] = getResources().getColor(R.color.dark_blue); GradientDrawable backColor = new GradientDrawable(Orientation.TOP_BOTTOM, colors); backColor.setBounds(0, 0,0, 4); //finally create a layer list and set them as background. Drawable[] layers = new Drawable[2]; layers[0] = backColor; layers[1] = shadow; LayerDrawable layerList = new LayerDrawable(layers); setBackgroundDrawable(layerList); </code></pre> <p>The problem is that it seems that setting the bounds is useless or doesn't work the same way as (android:top, android:bottom xml parameters). The resulting background is each layer painted from top to bottom, one above the other.</p> <p>I want to generate something like this: <a href="http://i49.tinypic.com/2nueqf.png">IMG http://i49.tinypic.com/2nueqf.png</a></p>

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.
