    <p>I am trying to create a button where I can hide or show the status bar on my tablet.</p> <p>I've put in the onCreate</p> <pre><code>getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN); getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); </code></pre> <p>and in the buttons show: </p> <pre><code>WindowManager.LayoutParams attrs = getWindow().getAttributes(); attrs.flags &amp;= ~WindowManager.LayoutParams.FLAG_FULLSCREEN; getWindow().setAttributes(attrs); </code></pre> <p>hide:</p> <pre><code>WindowManager.LayoutParams attrs = getWindow().getAttributes(); attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN; getWindow().setAttributes(attrs); </code></pre> <p>Any hints/tipps?</p> <p>//edit</p> <p>I've looked at this hint here: <a href="http://android.serverbox.ch/?p=306" rel="noreferrer">http://android.serverbox.ch/?p=306</a> and changed my code like this:</p> <pre><code>private void hideStatusBar() throws IOException, InterruptedException { Process proc = Runtime.getRuntime().exec(new String[]{"su","-c","service call activity 79 s16 com.android.systemui"}); proc.waitFor(); } private void showStatusBar() throws IOException, InterruptedException { Process proc = Runtime.getRuntime().exec(new String[]{"am","startservice","-n","com.android.systemui/.SystemUIService"}); proc.waitFor(); } </code></pre> <p>So if I click on my buttons an the methods are called I can see that something is happening because the app is waiting some seconds. I also looked into LockCat and see that something is happening.</p> <p>show: <a href="http://pastebin.com/CidTRSTi" rel="noreferrer">http://pastebin.com/CidTRSTi</a> hide: <a href="http://pastebin.com/iPS6Kgbp" rel="noreferrer">http://pastebin.com/iPS6Kgbp</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.
