    <p>To change the led color: <a href="https://stackoverflow.com/questions/6169291/changing-led-color-for-notifications">Check this link </a></p> <p>For the BATTERY_LOW you will ned a broadcastreceiver: <a href="http://www.tutorialforandroid.com/2009/01/getting-battery-information-on-android.html" rel="nofollow noreferrer">Check this link</a></p> <p>Ok.</p> <p>First, create a file in the values folder. Call it something like "preference_res.xml". Then add the following:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;resources&gt; &lt;string-array name="prefColor"&gt; &lt;item&gt;None&lt;/item&gt; &lt;item&gt;Blue&lt;/item&gt; &lt;item&gt;Green&lt;/item&gt; &lt;item&gt;Yellow&lt;/item&gt; &lt;item&gt;Other Color&lt;/item&gt; &lt;/string-array&gt; &lt;string-array name="prefColorVal"&gt; &lt;item&gt;-1&lt;/item&gt; &lt;item&gt;-2&lt;/item&gt; &lt;item&gt;79&lt;/item&gt; &lt;item&gt;24&lt;/item&gt; &lt;item&gt;25&lt;/item&gt; &lt;item&gt;27&lt;/item&gt; &lt;item&gt;80&lt;/item&gt; &lt;/string-array&gt; &lt;/resources&gt; </code></pre> <p>(Be aware that the prefColorVal items should ref to the value you want the radio button to have. The values shown here are random.)</p> <p>In your preference.xml, add something like this:</p> <pre><code>&lt;ListPreference android:dialogTitle="Choose color" android:entries="@array/prefColor" android:entryValues="@array/prefColorVal" android:key="bat_below_15" android:negativeButtonText="Cancel" android:positiveButtonText="Save" android:summary="Choose color when below 15" android:title="Color when below 15" /&gt; </code></pre> <p>If you don't know how to get or use these values, here are some pointers, but you should google this stuff:</p> <pre><code>preferences = PreferenceManager.getDefaultSharedPreferences(ctx); </code></pre> <p>and use this to get the value:</p> <pre><code> preferences.getString("bat_below_15", Blue)); </code></pre> <p>Hope it helps. </p>

    1. COWell, i already have a broadcastreceiver..the problem are the radio buttons in the preferences. I want something like "show the color of led when the battery level is around 15%". And you can choose the color from a dialog with the radio buttons group..how can i do it?

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.
