机器人的MediaController - 确定在布局XML中的MediaController [英] android mediacontroller - defining the mediacontroller in the layout xml
问题描述
在上的MediaController部件我读了Android文档
In the android documentation on the MediaController widget I read
像展（）和隐藏（）函数时，有没有效果的MediaController
在XML布局创建。
Functions like show() and hide() have no effect when MediaController is created in an xml layout.
，它指向了的MediaController可以在XML布局中限定的事实。因为我想一个控制器，它永远不会隐藏，也没有走集中，这样就可以点击我试图去XML布局方式，屏幕的其余部分的按钮。正如我不能得到这个工作我在寻找如何在布局XML定义它使用的MediaController一个例子。
which points to the fact the the mediacontroller can be defined in the xml layout. As I want a controller which never hides and also doesn't take the focus so that it is possible to click buttons on the rest of the screen I tried to go the xml layout way. As I can't get this to work I am looking for an example on how to use MediaController by defining it in the layout xml.
任何暗示高度AP preciated
Any hint highly appreciated
推荐答案
我发现为Android 2.x的一种解决方法可悲的是它似乎并没有在4.x的工作。
I found one workaround for Android 2.x. Sadly it doesn't seem to work in 4.x.
您需要调用 setAnchorView（）来显示的MediaController。这code中的Android 2.2和2.3.6为我工作，但在4.0.4导致崩溃：
You need to call setAnchorView() to show the MediaController. This code worked for me in Android 2.2 and 2.3.6, but caused crash in 4.0.4:
mediaController.setAnchorView(mediaController);
我也试过路过的活动内容以 setAnchorView（），但它仍然在4.0.4崩溃。
I also tried passing activity content view to setAnchorView(), but it still crashing in 4.0.4.
最可靠的方法是编程实例它作为文档说：
The most reliable way is to instantiate it programatically as said in documentation:
要使用这个类的方法是编程实例化。
The way to use this class is to instantiate it programatically.
