实施AsyncQueryHandler [英] Implementing AsyncQueryHandler
问题描述
我想实现 AsyncQueryHandler
,因为我遇到这个完全相同的问题,<一个href="http://stackoverflow.com/questions/11604914/contentprovider-insert-always-runs-on-ui-thread">link但我没有看到任何其实现的例子或任何东西。
I am trying to implement AsyncQueryHandler
because I am experiencing the same exact problem in this link but I dont see any example or anything about implementing it.
我试图做
AsyncQueryHandler handler = new AsyncQueryHandler(getContentResolver());
因为这是构造显示在文档但我得到一个错误说无法实例的类型AsyncQueryHandler
让我怎么使用它呢?
since that is what the constructor shows in the docs but I get an error saying cannot instantiate the type AsyncQueryHandler
so how do I use it then?
推荐答案
<一个href="http://developer.android.com/reference/android/content/AsyncQueryHandler.html">AsyncQueryHandler是一个抽象类,所以你不能直接实例化。你需要它的子类。
AsyncQueryHandler is an abstract class, thus you cannot instantiate it directly. You need to subclass it.
