    <p>So, turns out it's pretty simple, I recently implemented in my app.</p> <p>The items that need to be shown in the overflow menu, nest them under one menu item as follows:</p> <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;item android:id="@+id/empty" android:orderInCategory="101" android:showAsAction="always" android:icon="@drawable/ic_action_overflow"&gt; &lt;menu&gt; &lt;item android:id="@+id/action_settings" android:orderInCategory="96" android:showAsAction="never" android:title="@string/menu_settings" android:icon="@drawable/ic_action_settings"/&gt; &lt;item android:id="@+id/action_share" android:orderInCategory="97" android:showAsAction="never" android:title="@string/menu_share" android:icon="@drawable/ic_action_share"/&gt; &lt;item android:id="@+id/action_rate" android:orderInCategory="98" android:showAsAction="never" android:title="@string/menu_rate" android:icon="@drawable/ic_action_important"/&gt; &lt;item android:id="@+id/action_feedback" android:orderInCategory="99" android:showAsAction="never" android:title="@string/menu_feedback" android:icon="@drawable/ic_action_edit"/&gt; &lt;/menu&gt; &lt;/item&gt; &lt;/menu&gt; </code></pre> <p>Now, edit the main activity file as follows:</p> <pre><code>package com.example.test; //all your import statements go here Menu mainMenu=null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); mainMenu=menu; return true; } //Menu press should open 3 dot menu @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode==KeyEvent.KEYCODE_MENU) { mainMenu.performIdentifierAction(R.id.empty, 0); return true; } return super.onKeyDown(keyCode, event); } </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.
