Question

首先，我有一个带有expandablelistview的应用程序，到目前为止所有内容都已经开始了，但我想要做的是当每个父母的每个孩子都被点击时，一个新的YouTube视频被打开，我知道如何做但这个问题是每个列表中有很多项目，每个项目/孩子都会播放自己的视频。

我有没有办法在onInitializationSuccess方法中执行一个IF语句，它根据在我可扩展列表类中单击的子项，从创建的数组中获取一个项目。

public class Videos extends YouTubeBaseActivity implements
        YouTubePlayer.OnInitializedListener {

    static private final String DEVELOPER_KEY = "wqafesf968se15fes6fe...";
    static private final String VIDEO = "MveeQaTefwaewRE";

    public final String VideoList[]={"MvJT5E","LKKdpJU"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.videos);

        YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
        youTubeView.initialize(DEVELOPER_KEY, this);
    }

    @Override
    public void onInitializationFailure(Provider provider,
            YouTubeInitializationResult error) {

        Toast.makeText(this, "Oh no! " + error.toString(), Toast.LENGTH_LONG)
                .show();
    }



@Override
        public void onInitializationSuccess(Provider provider,
                YouTubePlayer player, boolean wasRestored) {
            player.loadVideo(VIDEO);
            // IF statement here with an item from the array depending on which child was clicked
player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE);
        }

    }

这是onClick方法，它在ANOTHER类中，它扩展了Activity

    public boolean onChildClick(ExpandableListView parent, View v,
            int groupPosition, int childPosition, long id) {

        final String selected = (String) listAdapter.getChild(groupPosition, 1);                

        switch (groupPosition) {
        case 0:
            switch (childPosition) {
            case 0:
                Intent adobeEFintro = new Intent("com.program.STUFF"); 
                startActivity(adobeEFintro);
                break;
            case 1:
                break;
            case 2:
                break;
            case 3:
                break;

            default:
                break;
            }
            break;
        case 1:
            break;
        case 2:
            break;
        case 3:
            break;
        case 4:
            break;
        default:
            Toast.makeText(getBaseContext(), selected, Toast.LENGTH_SHORT).show();
            break;
        }

        return false;
    }

您可以在包含onClick方法的类中构造一个URLS数组，该方法将URL直接传递给Video类。这在解释中 How do I pass data between Activities in Android application?

Intent intent = new Intent(v.getContext(), Video.class);
intent.putExtra("URL", <insertUrlHere>);
startActivity(intent)

在视频活动中：

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String value = extras.getString("URL");
}

使用另一个类中的expandablelistview中的项来创建IF语句
