使用YouTubePlayerSupportFragment崩溃 [英] crash using YouTubePlayerSupportFragment

问题描述

我有一个从片段开始的活动

I have an activity that extends from a fragment

public class Youtube_visor extends Fragment{ ...

以及使用YouTubePlayerSupportFragment创建新的YouTube播放器的方法

and a method that creates a new YouTube player using YouTubePlayerSupportFragment

这是我的代码:

public void playVideo () {

        fragmentManager = getActivity().getSupportFragmentManager();
        fragmentTransaction = fragmentManager.beginTransaction();

        YouTubePlayerSupportFragment player = new YouTubePlayerSupportFragment();
        fragmentTransaction.add(R.id.fragmentz, player); // fragmentz es un linearlayout que hay en el xml
        fragmentTransaction.commit();

        player.initialize(Static_generals.youtubeKey,new OnInitializedListener() {

            public void onInitializationSuccess(Provider arg0,
                    YouTubePlayer arg1, boolean arg2) {
                if (!arg2) {
                    arg1.cueVideo("3OhGkg_XT3o");
                }
            }

            @Override
            public void onInitializationFailure(Provider arg0,YouTubeInitializationResult arg1) {
                // Error
            }
        });
    }

这在平板电脑上完美运行，我有一个包含两个片段的活动，左边是视频列表，右边是创建YouTube播放器的片段

This works perfectly on the tablet, I have an activity with two fragments, left a list of videos, and right, the fragment which create the YouTube player

我的问题是我不想创建一个新的YouTubePlayer，我想在xml中声明一个并始终使用它. 这是在xml中声明的片段:

My problem is I do not want to create a new YouTubePlayer, I want to declare one in the xml and always use that. This is the fragment declared in the xml:

   <fragment
      android:name="com.google.android.youtube.player.YouTubePlayerFragment"
      android:id="@+id/youtube_fragment"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

现在，在我的代码中，我替换以下行:

Now, in my code, I replace this line:

YouTubePlayerSupportFragment player = new YouTubePlayerSupportFragment();

并添加以下新行:

YouTubePlayerSupportFragment player = (YouTubePlayerSupportFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.youtube_fragment);

但总是崩溃. 我搜索了有关此信息，但没有太多可用信息，或者找不到它:)

but always crash. I searched for information about it but there is not much available, or have not found it :)

我在做什么错了?

我猜我在说我的片段是错误的，因为当我做一个新的片段时可以正常工作

I guess I'm calling my fragment wrong, because when I do a new one working properly

感谢您的帮助.

感谢和亲切问候

推荐答案

看起来您已经在XML中放入了YouTubePlayerFragment，但是您试图将其转换为代码中的YouTubePlayerSupportFragment.尝试替换此行:

Looks like you've put a YouTubePlayerFragment in your XML, but you're trying to cast it to a YouTubePlayerSupportFragment in the code. Try replacing this line:

android:name="com.google.android.youtube.player.YouTubePlayerFragment"

与此:

android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
