Android 如何将字符串从Listview传递到另一个类中的片段？

我有一个android项目，其中-ListClass有一个Listview。单击Listview的一个项目后，打开CardFlipActivity，其中包含两个片段，设置为查看pageflip操作。我需要在CardFlip活动的顶部片段上播放视频，并在底部片段中显示图像

1） 如何从ListClass中的listview项目开关位置传递（原始文件夹视频文件和图像文件）的字符串，以检索并显示在CardFlipActivity的片段中

列表类代码：

public class ListClass extends ListActivity {
static final String VIDEO_PATH = null;
static final String IMAGE_PATH = null;
static final String VIDEO_NAME = null;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // storing string resources into ArrayList
    String[] coronary_pathology_clips = getResources().getStringArray(R.array.coronary_pathology_clips);
    ArrayList<String> coronary_pathology_clipsList = new ArrayList<String>(Arrays.asList(coronary_pathology_clips));

    // Binding resources ArrayList to CathListAdapter
    setListAdapter(new CathListAdapter(this,R.layout.list_item, coronary_pathology_clipsList));
    getListView().setBackgroundColor(Color.GRAY);
}   
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    super.onListItemClick(l, v, position, id);
    change(position);
}
void change(int position){
      String selectedValue = (String) getListAdapter().getItem(position);
      Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show();

    Intent intent = new Intent(getApplicationContext(), CardFlipActivity.class);

    switch(position){  

    case 0 :
        String path1 = "android.resource://" + getPackageName() + "/" + R.raw.video1;
        String path1a = "android.resource://" + getPackageName() + "/" + R.raw.image1;

        intent.putExtra (VIDEO_PATH, path1);  
        intent.putExtra (IMAGE_PATH, path1a);               

        break;
    case 1 :
        String path2 = "android.resource://" + getPackageName() + "/" + R.raw.video2;
        String path2a = "android.resource://" + getPackageName() + "/" + R.raw.image2;

        intent.putExtra (VIDEO_PATH, path2);  
        intent.putExtra (IMAGE_PATH, path2a);   
        break;

    } 
    Bundle dataBundle = new Bundle();
    dataBundle.putString("VIDEO_NAME", selectedValue);
    intent.putExtras(dataBundle);
    startActivity(intent);
}

}

您可以使用startactivityforresult从listclass获取结果

要将字符串传递给另一个片段，可以使用

setArgument（bundle）

fragment方法。

要接收这些字符串，您可以

getArgument（）

method.

如果可能的话，请详细说明一下好吗？我应该在ListClass中编写什么代码，应该在片段中添加什么代码？请查看Android开发者页面：
