    <p>There are multiple ways to achieve a tutorial-like overlay. Probably the easiest one is to use specially prepared <a href="http://developer.android.com/guide/topics/ui/dialogs.html" rel="noreferrer">Dialog</a> window with transparent background and without dim behind.</p> <h2>Using custom <code>Dialog</code> for tutorial overlay</h2> <p>First of all we have to prepare content for the <code>Dialog</code>. In this example there will be one <code>TextView</code> inside <code>RelativeLayout</code> which is the most useful layout here.</p> <p>Content of <code>info_overlay.xml</code> file:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"&gt; &lt;TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:background="@android:color/darker_gray" android:padding="3dp" android:text="TextView" android:textColor="@android:color/white" /&gt; &lt;/RelativeLayout&gt; </code></pre> <p>Now, we can use this layout to create our <code>Dialog</code>:</p> <pre><code>public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Dialog overlayInfo = new Dialog(MainActivity.this); // Making sure there's no title. overlayInfo.requestWindowFeature(Window.FEATURE_NO_TITLE); // Making dialog content transparent. overlayInfo.getWindow().setBackgroundDrawable( new ColorDrawable(Color.TRANSPARENT)); // Removing window dim normally visible when dialog are shown. overlayInfo.getWindow().clearFlags( WindowManager.LayoutParams.FLAG_DIM_BEHIND); // Setting position of content, relative to window. WindowManager.LayoutParams params = overlayInfo.getWindow().getAttributes(); params.gravity = Gravity.TOP | Gravity.LEFT; params.x = 100; params.y = 20; // If user taps anywhere on the screen, dialog will be cancelled. overlayInfo.setCancelable(true); // Setting the content using prepared XML layout file. overlayInfo.setContentView(R.layout.info_overlay); overlayInfo.show(); } </code></pre> <h3>Result</h3> <p>Below is the screenshot of the above solution working. Note the <code>TextView</code> over <code>ActionBar</code>.</p> <p><img src="https://i.stack.imgur.com/08xlL.png" alt="enter image description here"></p> <h3>A few notes about solution</h3> <ul> <li>If you'll have a dedicated button to dismiss tutorial you can probably use <code>setCancelable(false)</code> to avoid accidental closing of tutorial.</li> <li>This solution works with any theme with any action bar solution (either OS-provided, <em>Android Support Library</em> or <em>ActionBar Sherlock</em>)</li> </ul> <h2>Other solutions/helpers</h2> <p>Take a look at <a href="https://github.com/Espiandev/ShowcaseView" rel="noreferrer">Showcase View library</a> as it focuses on creating tutorial-like screens in easy way. I'm not sure however that it can easily overlay actionbars.</p>

    2. CO@Jovan Hope it helps. Please move your second question about visibility of items in actionbar to separate posting. It'll for sure get more attention from SO users.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
