android-3.0-honeycomb

问题 In Android 2.3 and below, you could make an application full screen, and then "hijack" the menu/back/search buttons by just returning false onKeyDown()... and registering the app as a default home launcher application, that way, there's no way to exit the application. In Android 3.0 (Honeycomb) the navigation buttons (System Bar) is always present, I'd like to hide it. Is it possible? FYI, I am not publishing this application on the Android Market. This is an internal application for devices

问题 I have a Nexus One (rooted) and a Xoom (stock, not rooted). I have developed on my Nexus for quite some time, without any problems. I'm facing one with the Xoom, however, as it is not rooted. Indeed, I use sqlite databases in my apps, and I would like to debug them using sqlite3 as I do on my Nexus. It doesn't work! $ pwd / $ id uid=2000(shell) gid=2000(shell) groups=1003(graphics),1004(input),1007(log),1009(mount),1011(adb),1015(sdcard_rw),3001(net_b_admin),3002(net_bt),3003(inet) $ sqlite3

问题 I'm developing a presentation style application for HoneyComb Tablets. At one stage the tablet may be passed around a room for people to interact with. If possible I would like to prevent malicious users from navigating away from the current activity. So far I have overwritten the onBackPressed() to prevent finishing the activity but users can still press the other buttons on the status bar and also leave the app via notifications that pop up. Any suggestions or possible solutions? Thanks 回答1

问题 I am currently working on an Android tablet application which has two fragments, a list fragment and a details fragment. I am trying to make my list similar to People and Email where when selected the item background changes and a triangle is positioned on the right hand side of the list. I am currently having difficulties setting the background of the item selected in the list. As I understand in the list view I should set android:listSelector to a drawable and all should work. <LinearLayout

问题 I'm building compound controls (UI controls that consist of multiple standard UI controls) and I need HW acceleration (Honeycomb only app). The typical control will look like this: ViewGroup (some layout subclass) with a NinePatchDrawable background + setColorFilter on the background drawable. Inside that, one or more Views with a NinePatchDrawable background + setColorFilter on the background drawable. I'll build up my UI from compound controls like this. Will this hierarchy be hardware

问题 I just got a Xoom on Wednesday, and upon loading my apps onto it, they run in a small window, as if they are being run on a smaller device. Various other apps fill the screen of the Xoom, although they don't seem to be using any specific honeycomb APIs, as they just seem to be the same UI I get on my phone, just stretched to fit. How would I go about getting my apps to fill the screen? Do I have to use fragments, or is there a simpler way? 回答1: I figured it out: I simply had to set the
