안녕하세요 초보 개발자입니다.

Sdcard 에 저장되어있는 Folder 리스트에는 각각에 이미지가 들어있는데

 폴더에 들어있는 모든 이미지가 gridview 형식으로 나타나고 있습니다.

각 폴더에서 이미지를 gridview 형식으로 보여주고 싶은데  어떻게 해야될지
부탁드립니다.


아래의 코드는  하나의 Folder 를 클릭 했을때 gridview 이미지를 보여주는 부분입니다.

    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.gridview);
            init_phone_image_grid();
      }
      private void init_phone_image_grid() {
            String[] img = { MediaStore.Images.Thumbnails._ID };
          //  imagecursor = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null,
          //      null, MediaStore.Images.Thumbnails.IMAGE_ID + "");
            image_column_index = imagecursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
          
            count = imagecursor.getCount();
            imagegrid = (GridView) findViewById(R.id.PhoneImageGrid);
            imagegrid.setAdapter(new ImageAdapter(getApplicationContext()));
            }

      public class ImageAdapter extends BaseAdapter {
            private             Context mContext;
            public ImageAdapter(Context c) {
                  mContext = c;
            }
            public int getCount() {
                  return count;
            }
            public Object getItem(int position) {
                  return position;
            }
            public long getItemId(int position) {
                  return position;
            }
            public View getView(int position,View convertView,ViewGroup parent) {
                  System.gc();
                  ImageView i = new ImageView(mContext.getApplicationContext());
                  if (convertView == null) {
                        imagecursor.moveToPosition(position);
                        int id = imagecursor.getInt(image_column_index);
                        i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
                          ""+ id));
                        i.setScaleType(ImageView.ScaleType.CENTER_CROP);
                        i.setLayoutParams(new GridView.LayoutParams(92, 92));
                  }
                  else {
                        i = (ImageView) convertView;
                  }
                  return i;
            }
      }
