我怎样才能得到一个Android的MediaController从布局XML的出现？ [英] How can I get an Android MediaController to appear from layout xml?

问题描述

我已经创建了以下XML一个layout.xml文件，但我不能得到的MediaController出现在所有。

I've created a layout.xml file with the following XML, but I can't get the MediaController to appear at all.

<MediaController android:id="@+id/media_controller"
    android:layout_width="fill_parent"
    android:layout_height="200px"
    android:visibility="visible"/>

在code，我可以从code，呼叫显示（），等对它的引用，但它永远不会出现。

In code, I can obtain a reference to it from code, call show(), etc, but it never appears.

我已经注意到了Android开发文档中（<一href="http://developer.android.com/reference/android/widget/MediaController.html">MediaController.html)它指出，使用这个类的方法是编程实例化。，所以也许我是一个dufus，只是需要做一些不同的事情，如不这样做我在做什么。）

I have noticed in the android dev documentation (MediaController.html) that it states, "The way to use this class is to instantiate it programatically.", so maybe I'm a dufus and just need to do something differently such as not do what I'm doing. :)

我可以，如果我编程方式做一次它出现，但我需要它总是出现在屏幕上。我只是愚蠢，或它只是并不意味着通过XML被夸大？

I CAN get it to appear if I do it programmatically, but I need it to always appear on the screen. Am I just being stupid, or is it just not meant to be inflated via XML?

推荐答案

从此示例项目：

ctlr=new MediaController(this);
ctlr.setMediaPlayer(video);
video.setMediaController(ctlr);

然后，它会在你挖掘朝着底部边缘的 VideoView 。

在屏幕上保持它所有的时间方面......我不知道这是可能的。你总是可以创建自己的控制器 - 这里创建自己的弹出半透明控制器的示例项目。这真的不是那么难，你会得到完全控制一切​​，包括安排它是在屏幕上所有的时间。

In terms of keeping it on screen all the time...I don't know if that's possible. You can always create your own controller -- here's a sample project that creates its own pop-up translucent controller. It's really not all that hard, and you get full control over everything, including arranging for it to be on-screen all the time.
