    <p>I am implementing an Android Activity from which other Activities will be derived from. So basically I have this setup of an InventoryActivity and its parent class, ListActivity:</p> <pre><code>public class MyListActivity extends Activity { protected Context mContext; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mContext = this.getBaseContext(); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.options, menu); Log.d("Creating options menu", "True"); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { Log.d("Preparing options menu", "True"); return super.onPrepareOptionsMenu(menu); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.save: return(true); case R.id.revert: return(true); } return(super.onOptionsItemSelected(item)); } } public class InventoryActivity extends MyListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.inventory); } } </code></pre> <p>And I also have this in options.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt; &lt;item android:id="@+id/card_list_save" android:icon="@drawable/ic_menu_save" android:title="Save"/&gt; &lt;item android:id="@+id/card_list_revert" android:icon="@drawable/ic_menu_revert" android:title="Revert" /&gt; &lt;/menu&gt; </code></pre> <p>If necessary, this is my layout for inventory.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" &gt; &lt;Button android:id="@+id/callSearch" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Search"/&gt; &lt;ScrollView android:layout_width="fill_parent" android:layout_height="wrap_content"&gt; &lt;LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" android:id="@+id/inventory"/&gt; &lt;/ScrollView&gt; &lt;/LinearLayout&gt; </code></pre> <p>However, when I press the menu button, nothing happens. The Log messages in the onCreateOptionsMenu method does not appear. Instead all I can see is the following:</p> <pre><code>02-04 11:36:58.313: W/KeyCharacterMap(31464): No keyboard for id 0 02-04 11:36:58.313: W/KeyCharacterMap(31464): Using default keymap: /system/usr/keychars/qwerty.kcm.bin </code></pre> <p>But what baffles me the most is that this code works in other Activities, such as my launcher Activity. But by the concept of object oriented programming, the InventoryActivity should call the overriding methods in the MyListActivity. I am completely stuck and I need help.</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.

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