Body
Lets assume, that I have two activities. One called MainActivity, and the other called PopupActivity. I want to have a context menu in MainActivity, after the user visited PopupActivity. <pre><code> Main [no menu] --> startActivity() / startActivityForResult() ==> Popup --> back / finish() ==> Main [now has menu]. </code></pre> Environment details: <ul> <li>minSDK: 10 (needed for backward compatibility)</li> <li>targetSDK: 17</li> <li>targetDevice: GalaxyTab 2.0</li> </ul> If the MainActivity has at least one element at the begining state, i can add / remove the desired menu items via onPrepareOptionsMenu. But if the MainActiviy has 0 menu elements inside, android doesn't even render the menu button on the top right corner. My question is: <ul> <li>What do i miss? </li> <li>How to tell android, to render the menu button, because i want to add menu items to it.</li> </ul> Workaround soultions can't work (like separating the Activity into two, etc.), because the whole problem is a bit more complex, but the core of it is this. I don't need menu items at the begining state, and i need them in a second one. main_menu.xml: <pre><code><menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/menu_add" android:title="@string/add"></item> <item android:id="@+id/menu_remove" android:title="@string/remove" ></item> </menu> </code></pre> MainActivity.java <pre><code>@Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.main_menu, menu); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { if (initState) { menu.findItem(R.id.menu_add).setVisible(false); menu.findItem(R.id.menu_remove).setVisible(false); } else { menu.findItem(R.id.menu_add).setVisible(true); menu.findItem(R.id.menu_remove).setVisible(true); } return super.onPrepareOptionsMenu(menu); } </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.
