问题 I want to change the color of the blinking cursor in a SearchView in the Actionbar (I'm using Actionbar Sherlock for compatibility). Until now I've managed to change the color of the cursor for a EditText element. This SO post helped me to accomplish that and the style I'm using for the EditText looks like this: <style name="CustomTheme" parent="Theme.Sherlock.Light"> <item name="android:editTextStyle">@style/edittext_style</item> </style> <style name="edittext_style" parent="@android:style

问题 I have an activity using ActionBarSherlock with ActionBar.NAVIGATION_MODE_LIST . When entering the page I want the spinner in the action bar to expand programmatically after it's populated with items so the user needs to pick an item. As of now the first item in the adapter is selected automatically. I can't figure out a nice way to expand the spinner in the action bar programmatically. Do I need to use a custom view to achieve this behavior? I've looked on the action bar with the

(I do totally understand the showAsAction options, and tried them all.) [B] Regarding using text or an icon, I tried all permutations. So what happens? When I run it on a device (10+ tested). It simply shows as many

问题 I'm developing for android 3+ In my action bar i have a drop-down list(see how to hide/unhide the actionbar list on android 3? for the dropdown i intend). The problem is i need to do a certain action when the user selects something, but Android calls onNavigationItemSelected() as soons as it draws the view, so no selection actually happened.
