我在edittext中粘贴了一个视频链接。我希望在更改链接并在其后单击按钮时重新加载视频。编辑文本采用 http 地址，并相应地拆分它以获得 YouTube 播放器的确切链接。每次更改地址时，传递给 YouTube 播放器的地址字符串也会更改。

我记录了它，它工作正常。但问题是，当我第一次粘贴 URL 时，它工作正常并加载了视频，但是一旦加载了视频，我更改了 URL 并按下按钮播放视频，什么也没有发生。我猜播放器视图已初始化，我无法重新初始化它？有没有办法重新初始化它？

这是我的 XML 代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
  >
    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/search"
        android:hint="Paste the link here"
        />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Play Video"
        android:layout_centerHorizontal="true"
        android:layout_below="@+id/search"
        android:id="@+id/play"/>

    <com.google.android.youtube.player.YouTubePlayerView
        android:id="@+id/youtube"
        android:layout_below="@+id/play"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fff"/>
</RelativeLayout>

java文件的代码是：

public class YoutubeMain extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener {
    public static final String API_KEY = "api key";
    public String VIDEO_ID;
    Button playvideo;
    EditText videoid;

                if (videoid.getText().toString().contains("="))
                    {
                        Log.d("Youtube","the id is:"+videoid.getText().toString());
                        int start = videoid.getText().toString().indexOf("=");

尝试这个！！！

private static final int RECOVERY_REQUEST = 1;

 @Override
    public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
        if(!b){
            startHttp(strUrl, youTubePlayer);
        }
    }

@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult errorReason) {
    if (errorReason.isUserRecoverableError()) {
        errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
    } else {
        String error = String.format(getString(R.string.player_error), errorReason.toString());
        Toast.makeText(this, error, Toast.LENGTH_LONG).show();
    }
}

private void startHttp(final String strUrl, final YouTubePlayer youTubePlayer) {
     youTubePlayer.cueVideo(strUrl);
}


@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == RECOVERY_REQUEST) {
            // Retry initialization if user performed a recovery action
            getYouTubePlayerProvider().initialize(Config.YOUTUBE_API_KEY, this);
        }
    }

    protected YouTubePlayer.Provider getYouTubePlayerProvider() {
        return youTubePlayerView;
    }
