问题 I've got an app that uses the accessibility service to monitor for events. It's always worked fine in versions of android up to ICS, but with Jelly bean I'm not having much luck. As the documents mention I've added android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" to my service in the manifest file. This causes the app to work fine using the declarative xml method for the xml. The problem is on backwards compatibility. For versions such as gingerbread I'm now getting the

问题 I'm working on an Android TV application but I'm not quite happy with the standard shadow rendered by the VerticalGridFragment , I'd like to have it smaller and a bit less darker. I've searched through the code but I didn't find any full working solution. In my VerticalGridPresenter subclass, the only method I can override is createShadowOverlayOptions but I can't get the result I want.

问题 I am using a ViewPager from Android support v13 and I'd like to scroll to a specific item using setCurrentItem(int) , but when I try to scroll more than 2 pages the application freezes, and after a few seconds the system shows an ANR window. I tried to increase the offscreen screen limit using setOffscreenPageLimit(2) , that way it did not freeze when i tried to scroll 2 pages, but did the same for 3 pages. My problem is that my fragments are pretty memory consuming so I would not like to

问题 With the previous versions of AppCompat it was easy to get the ActionBar 's title TextView and modify it. There is the method I was using: private TextView getActionBarTitleView() { int id = getResources().getIdentifier("action_bar_title", "id", "android"); return (TextView) findViewById(id); } And then to change the alpha's value of the title: getActionBarTitleView().setAlpha(ratio*255); Now for some reasons, "action_bar_title" with the lastest AppCompat version isn't working anymore. When I

问题 I'm surprisingly struggling to get hold of the instance of a service which is derived from MediaBrowserServiceCompat . For a typical service, to achieve that, a local binder is used class MyService extends MediaBrowserServiceCompat { class MyBinder extends Binder { public MyService getService() { return MyService.this; } private final MyBinder binder = new MyBinder(); @Override public IBinder onBind(Intent intent) { return binder; } public void doMagic() { // <-- How to call this from

问题 I dont know how to explain this, so i uploaded a video in Youtube. Everything works fine when i am adding pages. Also removing page works if i start at the end of the list and move progressively to the first page, but if i remove somewhere between 0-end and after that i add page, i am getting a blank page.
