    <p>I am creating an app, with resources that can be reused (because buttons are always the same, but mirrored or rotated). I do want to use the same resource so I don't have to add 3 more resources that are exactly like the original but rotated. But I also don't want to mix the code with things that can be declared in the XML or make transformations with a matrix that will cost processing time.</p> <p>I've got a two state button declared in an XML.</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:state_pressed="true" android:drawable="@drawable/and_card_details_button_down_left_onclick" /&gt; &lt;!-- pressed --&gt; &lt;item android:drawable="@drawable/and_card_details_button_down_left" /&gt; &lt;!-- default --&gt; &lt;/selector&gt; </code></pre> <p>and I want to reuse the drawable because it will be the same but rotated 90º and 45º and I assign to the button as a drawable.</p> <pre><code>&lt;Button android:id="@+id/Details_Buttons_Top_Left_Button" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/details_menu_large_button" /&gt; </code></pre> <p>I know that I can rotate it with a <a href="http://developer.android.com/reference/android/graphics/drawable/RotateDrawable.html" rel="noreferrer"><code>RotateDrawable</code></a> or with a <a href="http://developer.android.com/reference/android/graphics/Matrix.html" rel="noreferrer"><code>Matrix</code></a> but as I already explained I don't like that approach.</p> <p>Is it possible to achieve that directly on the XML or what do you think that will be the best way to do it? Put all resources but rotated, rotate them in the code?</p> <p>--- EDIT --- The answer of @dmaxi works great, this is how to combine it with an item list :)</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:state_pressed="true"&gt; &lt;rotate android:fromDegrees="90" android:toDegrees="90" android:pivotX="50%" android:pivotY="50%" android:drawable="@drawable/and_card_details_button_up_onclick"/&gt; &lt;/item&gt; &lt;item&gt; &lt;rotate android:fromDegrees="90" android:toDegrees="90" android:pivotX="50%" android:pivotY="50%" android:drawable="@drawable/and_card_details_button_up_onclick"/&gt; &lt;/item&gt; &lt;/selector&gt; </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.
