问题 How do I hide the ActionBar after starting the Contextual ActionBar? getActionBar() returns null in the ActionMode.Callback methods. Is it possible? I only want to show the Contextual ActionBar, not both as it does now. 来源： https://stackoverflow.com/questions/28220792/hide-actionbar-in-contextual-actionmode

问题 I'm trying to use ActionBarSherlock + ShareActionProvider in a SherlockActivity. I've already checked this ( NullPointerException using ShareActionProvider + actionbarsherlock) but it doesn't solve my problem. I think the code is correct, but I keep getting FC and this logcat: 07-25 15:31:26.758: E/AndroidRuntime(911): FATAL EXCEPTION: main 07-25 15:31:26.758: E/AndroidRuntime(911): java.lang.NullPointerException 07-25 15:31:26.758: E/AndroidRuntime(911): at com.corsalini.david.calcolopesi

问题 I'm using a ViewPager to display 4 different fragments. I use the action bar to display the tabs for the navigation. It looks like that: My problem is that initially 3 of the tabs are fully visible and the last one is partially visible. Clicking on any of the first 3 tabs is ok but when I click on the last one, the app crashes: 09-06 13:35:01.825: E/AndroidRuntime(6676): FATAL EXCEPTION: main 09-06 13:35:01.825: E/AndroidRuntime(6676): java.lang.IllegalStateException: Content view not yet

问题 I would like to center my app's title displayed on the ActionBar. So far I have customised its background color using only the style.xml file, like this: <!-- Application theme. --> <style name="AppTheme" parent="@android:style/Theme.Holo.Light"> <!-- All customizations that are NOT specific to a particular API-level can go here. --> <item name="android:actionBarStyle">@style/MyActionBar</item> </style> <style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar"> <item name=

问题 I have a fragment named as HomeFragment.java and it extends Fragment class. import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v7.widget.Toolbar; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import com.example.android.test.R; import android.support.v7.app.ActionBarActivity; import android.support.v7.widget.Toolbar; public class HomeFragment extends Fragment { private Toolbar toolbar; public View onCreateView

问题 This is very similar to the issue mentioned here, which mostly fixed my problem. However, if you are setting the title from a fragment that does not contribute to the options menu , then the title area won't expand. This can cause an ellipsis if the initial title was very small, even though there may be plenty of room in the action bar for it. My guess is that if the fragment does contribute to the options menu then it causes that title area's width to be recalculated. Is there a way to force

问题 I don't really like the new Action Bar Android has come up with -- and apparently forced me to use in later API levels. But, since it appears I'm stuck with it -- I have no more Menu Button and I need the functionality I've lost, I'd like to minimize the annoyance factor. Can anybody tell me how NOT to display the Icon/Logo? It's easy enough to suppress the Title, but the logo is still too much -- and provides zero helpfulness. Also, can anybody tell me how to reduce the height of the bar?
