Android - Images from Assets folder in a GridView
- by Saran
Hi,
I have been working on creating a Grid View of images, with images being present in the Assets folder. http://stackoverflow.com/questions/1933015/opening-an-image-file-inside-the-assets-folder link helped me with using the bitmap to read it. The code am currently having is:
public View getView(final int position, View convertView, ViewGroup parent)
{
try
{
AssetManager am = mContext.getAssets();
String list[] = am.list("");
int count_files = imagelist.length;
for(int i= 0;i<=count_files; i++)
{
BufferedInputStream buf = new BufferedInputStream(am.open(list[i]));
Bitmap bitmap = BitmapFactory.decodeStream(buf);
imageView.setImageBitmap(bitmap);
buf.close();
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
My application does read the image from the Assets folder, but it is not iterating through the cells in the grid view. All the cells of the grid view have a same image picked from the set of images. Can anyone tell me how to iterate through the cells and still have different images ?
I have the above code in an ImageAdapter Class which extends the BaseAdapter class, and in my main class I am linking that with my gridview by:
GridView gv =(GridView)findViewById(R.id.gridview);
gv.setAdapter(new ImageAdapter(this, assetlist));
Thanks a lot for any help in advance,
Saran
