我将一些图像和视频都存储在我的原始文件夹中。

视频播放良好，但是一旦我想显示图像，我就会得到：

即使图像在视频发生之前先开始

package com.example.tvrplayer;

public class MainActivity extends Activity implements OnCompletionListener {

    int playListIndex;
    int currentMedia;
    String mediaName;
    ArrayList<Integer> playList = new ArrayList<Integer>();
    private VideoView videoView;
    private ImageView imageView;
    Uri mediaPath;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        createPlayList();
        currentMedia = 1;
        try {
            playMedia(this, currentMedia);
        } catch (IOException e) {
            // TODO Auto-generated catch block

        currentMedia++;
        if (currentMedia > playList.size() - 1) {
            currentMedia = 0;
        }
        try {
            playMedia(this, currentMedia);
        } catch (IOException e) {
            e.printStackTrace();

    }
    private void playMedia(Context context, int playListIndex) throws IOException {
        int resourceID = playList.get(playListIndex); // This is the resource id
        String path = "android.resource://" + getPackageName() + "/" + resourceID;
        Uri uri = Uri.parse(path);
        String filename = context.getResources().getResourceName(resourceID);
        if (filename.contains("image")) {
            imageView = (ImageView)findViewById(R.id.imageView);
            imageView.setImageResource(resourceID);
        } else if (filename.contains("video")) {
            videoView = (VideoView) findViewById(R.id.videoView);
            videoView.setVideoURI(uri);
            videoView.start();
        }
    }

    private void createPlayList() {
        java.lang.reflect.Field[] fields = R.raw.class.getFields();
        for(java.lang.reflect.Field f : fields)
        try {

        java.lang.reflect.Field[] imagefields = R.drawable.class.getFields();
        for(java.lang.reflect.Field f : imagefields)
        try {
            playList.add(f.getInt(null));
            } catch (IllegalArgumentException e) {
            } catch (IllegalAccessException e) { }  
    }

}

这是控制台中出现的内容：

我需要播放原始文件夹中的图像，而不是这个应用程序的可绘制对象。难道我做错了什么？

在此处输入图像描述
