options-menu

I can create an Option Menu for a single Activity. But now I want to create a Logout option in the menu which should be available on all Activities in the App. Is there a possible way to create an Option menu once for an Application? I answered this once on SO, but i forgot where...so here i go again. Its quite Straightforward. Create a BaseActivity (extends Activity ). Implement all your Options Menu Code in this. Override your onOptionsMenu ,etc... Now, For all your other Activities, instead of extending Activity, extend BaseActivity . You'll end up deriving all the options menu code...nifty

I have a menu created through: @Override public boolean onCreateOptionsMenu(Menu menu) { menu.add("Email"); return super.onCreateOptionsMenu(menu); } But I can't remember how to set a onclicklistener so when its selected I can run my email function. Override onOptionsItemSelected(MenuItem item) . So it would be like @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case 0: // do whatever return true; default: return super.onOptionsItemSelected(item); } } EDIT: Since this has gotten so many points, I should note that it is very good to add ID's to the

Refresh is working [I figured it out by changing the method to read 'webView.reload();' instead of 'webView.refresh();' Can anyone assist with the forward and back? I have tried 'forward', 'canGoForward' and 'goForward' as well as 'back', 'canGoBack' and 'goBack'. There are no error codes however none of those methods actually do anything. public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); // Add menu items, second value is the id, use this in the onCreateOptionsMenu menu.add(0, 1, 0, "Back"); menu

Each time my Optionsmenu opens (onCreateOptionsMenu(..) is called), I get these warnings: "No keyboard for id 0" and "Using default keyMap: /system/usr/keychars/qwerty.kcm.bin" I couldn't find out what they mean, does anyone know ? I didn't like this answer . Here's the simple code I'm using: @Override public boolean onCreateOptionsMenu(Menu menu) { super.onCreateOptionsMenu(menu); getMenuInflater().inflate(R.menu.optmenu_start, menu); return true; } and the optmenu_start.xml: <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/optmenu_prefs" android:title=
