android-actionbar

问题 Please refer to my project at: https://github.com/paulpv/ToolbarSwitch I am working on a simple custom layout for the Android Toolbar (aka: new ActionBar). This simple control adds a Switch to the Toolbar, and can be seen here highlighted in magenta: My problem is that immediately when the overflow menu is pressed, the Switch's Text jumps to the top of the Toolbar, and remains that way when you close the overflow menu: A similar thing happens in Landscape orientation (the subtle difference

问题 My question is closely related to SearchView wrong alignment and SearchView positions when expanded in ActionBar but the answers posted there do not work. So, I'm using a SearchView in the Action Bar: <item android:id="@+id/action_search" android:icon="@drawable/navi_search" android:title="@string/action_search" android:showAsAction="ifRoom|collapseActionView" android:actionViewClass="android.widget.SearchView" /> It looks like this by default (top-right corner, next to overflow menu):

问题 Here is my problem. I have an app where I am using ActionBar Sherlock with tabs, fragments with option menus. Every time I rotate the emulator, menus are added for all the fragments even those that are hidded/removed (I tried both). This is the setting: One FragmentActivity, that has an ActionBar with final ActionBar bar = getSupportActionBar(); bar.addTab(bar.newTab() .setText("1") .setTabListener(new MyTabListener(new FragmentList1()))); bar.addTab(bar.newTab() .setText("2") .setTabListener

问题 Good morning, i am quite new in Android and i have a problem setting the color of the built-in action bar in Google Places Picker. The documentation of this one clearly says that the action bar color inherits the matherial theme style of the project. The problem is that i have Theme.AppCompat.Light.NoActionBar and the color of this style isn't passed to the Google Place Picker because it uses only the colors of material themes. I would like to ask if it's somehow possible to replace Theme

问题 I have to develop an actionBar with a custom shape for an android app. The actionBar is a rectangle as always, but every option (icon) I add to the actionBar has to be bigger than the actionBar and with a circle shape. Any ideas how to implement that feature? I can't find how to solve this problem. Thanks. 回答1: I think you should remove the ActionBar completely and make your own custom view with desired content (as mentioned) and put that view on top of each activity. Customizing action bar

问题 I am trying to create a tab that displays a list on the left hand fragment and a detailed fragment on the right. When a user clicks a list item, the right hand fragment should change to the appropriate one. I am new to android so I used a tutorial and I know I need to do something with the tablistener: public static class TabListener implements ActionBar.TabListener { private final Activity mActivity; private final String mTag; private final Class mClass; private final Bundle mArgs; private

问题 How can you change the tab text color of the action bar from Java code? Not switching to a different theme that was defined in an XML file, but something like .setTextColor(Color.GREEN). If there were a way to get the current (not custom) view, maybe I could try grabbing the TextView from there and changing it. 回答1: Figured it out.... You can pass in a SpannableString: SpannableString spannable = new SpannableString(myString); spannable.setSpan(new ForegroundColorSpan(Color.GREEN), 0,
