问题 How can I hide or remove the status bar in Android HoneyComb? Every time I run my application, I find some contents have to be covered by the status bar. I have try to change the AndroidManifest.xml , but nothing changed. 回答1: You don't. It's considered a permanent screen decoration in the same way that capacitive home/menu/etc. buttons below the touchscreen on Android phones are. How are you measuring the space available for your content? 回答2: You can only dim the status bar. See How do I

问题 I have created an AppWidget for Honeycomb which is working well, except that when first installed, it does not show up in the Widgets menu so it can not be added to a home screen. Rebooting the device will allow it to show up, or during development, sending it twice from Eclipse will cause it to show up. Any ideas? Thanks! 回答1: Appearently EboMike was right, setting android:installLocation="internalOnly" did fix the issue. Without specifying an install location, it should have defaulted to

问题 My fragment loads its data into a tablelayout inside a scrollview. At first, it will load saying "Click on image to view more data". I have a onclick listener from the gallery that should delete all the rows from the tablelayout with tableLayout.removeAllViews(); . Then the fragment will add row/rows to a tablelayout inside a scrollview. The tablelayout should change on every click from the gallery. However I am getting: **java.lang.IllegalStateException: ScrollView can host only one direct

问题 Background: I recently purchased a Motorola XOOM Tablet along with the Desktop Dock and Bluetooth Keyboard accessories. The dock and keyboard work great, but when I take the tablet off the dock to move away from my desk, the keyboard still remains paired with the device and I have to manually change the settings to use the soft keyboard. The same goes for when I set it back on the dock, I need to manually switch it back. It's not a huge problem, but it would be nice not to have to think about

问题 I'd like to show a different fragment in a TabHost, for every tab. But it seems that there's no easy way to do this. TabHost can only accept A. Views or B. Intents that launch Activities when the user selects a tab. Going with A means that I have to initialize every fragment and load them into container Views that are given to the TabHost. But I want these fragments to load only when needed - when the user selects their tab that is. Going with B means that I load the fragments into separate

问题 I'm seeing a pretty odd problem. Essentially sometimes large bitmap memory allocations will fail even though there's apparently tons of memory. There are a number of posts that appear to ask a similar question but they are all related to pre-honeycomb android. My understanding is that images are allocated on heap now, instead of some outside memory. Anyway, please look at this log below: 10-14 13:43:53.020: INFO/dalvikvm-heap(31533): Grow heap (frag case) to 40.637MB for 942134-byte

问题 Device administration app can not be uninstalled if it is not disabled. User can disable "Device Administrators" from the settings. When company gives android devices to its employees, company wants to have a control over devices, their statuses and policies, but user can easily get rid of that control.
