Here is the source code i am using:
public class MyImage extends Activity {
/** Called when the activity is first created. */
Gallery gallery;
private Uri[] mUrls;
String[] mFiles=null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
File images = Environment.getDataDirectory();
File[] imagelist = images.listFiles();
mFiles = new String[imagelist.length];
for(int i= 0 ; i< imagelist.length; i++)
{
mFiles[i] = imagelist[i].getAbsolutePath();
}
mUrls = new Uri[mFiles.length];
for(int i=0; i < mFiles.length; i++)
{
mUrls[i] = Uri.parse(mFiles[i]);
}
Gallery g = (Gallery) findViewById(R.id.Gallery01);
g.setAdapter(new ImageAdapter(this));
g.setFadingEdgeLength(40);
}
public class ImageAdapter extends BaseAdapter{
int mGalleryItemBackground;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount(){
return mUrls.length;
}
public Object getItem(int position){
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent){
ImageView i = new ImageView(mContext);
i.setImageURI(mUrls[position]);
i.setScaleType(ImageView.ScaleType.FIT_XY);
i.setLayoutParams(new Gallery.LayoutParams(260, 210));
return i;
}
