The code I have works the first time the activity is created, but any time the activity is called again, I get a NullReference exception on "loadingItem" because onCreateOptionsMenu is called after onCreate . I tried using onPrepareOptionsMenu but the same thing. public class MyActivity extends SherlockActivity { private MenuItem loadingItem; @Override public void onCreate(final

问题 Good evening, i hope somebody could help me. Im developing a app where i use the action bar from the support library for pre 3.0-devices, but i have the problem, that espacially on the pre 3.0-devices no action bar is showing.

This goal is unique, because it is not just a custom spinner (easy to find tutorial on) or just an ActionBar icon placement (also easy), but rather

问题 I'm not able to change the color of the text of the action bar, the color of the background is working fine, but not the color of the text. <style name="MyTheme" parent="@android:style/Theme.Holo.Light"> <item name="android:actionBarStyle">@style/MyActionBar</item> <item name="android:titleTextStyle">@style/myTheme.ActionBar.Text</item> </style> <style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar"> <item name="android:background">#0E2F44</item> </style> <style name=

问题 I have just upgraded to the newest library version after Android Lollipop was released. After I fixed serveral doublicated attributes (which where caused by the Support Library) I updated my android-switch-backport, and it compiled again. However now I have no more the ActionBar, it is now a Toolbar. So far so good, but now is that Toolbar black and I have no idea why. So how can I change it back to my custom colors, I used Android Action Bar Style Generator, for generating all required
