I am trying to display images from sdcard and drawable inside gridview using the following code.But it doesn't works.It crashes in Galaxy Note due to Memory Error but displaying wrong images in emulator and also takes alot of time to display them.
DisplayImageOptions options = new DisplayImageOptions.Builder()
.cacheInMemory().cacheOnDisc()
.bitmapConfig(Bitmap.Config.RGB_565).build();
Adapter Class
public class GridAdapter extends BaseAdapter {
public GridAdapter(Context ctx) {
// TODO Auto-generated constructor stub
imageLoader = ImageLoader.getInstance();
imageLoader.init(ImageLoaderConfiguration.createDefault(ctx));
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return mImages.size();
}
@Override
public Object getItem(int pos) {
// TODO Auto-generated method stub
return mImages.get(pos);
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
public class ViewHolder {
ImageView image;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = getLayoutInflater().inflate(R.layout.grid_image,
parent, false);
holder.image = (ImageView) convertView
.findViewById(R.id.gridImage);
holder.image.setLayoutParams(new LinearLayout.LayoutParams(
width / 2, width / 2));
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if (mImages.get(position).getImageSource().equals("sdcard")) {
imageLoader.displayImage(mImages.get(position).getImages(),
holder.image,options);
} else {
String url = "drawable://"
+ Integer.parseInt(mImages.get(position).getImages());
imageLoader.displayImage(url, holder.image,options);
}
return convertView;
}
}
Update : I have around 30 images in gridview, at the beginning it just displays first image all over the place and it takes around 1 minute to display all the images correctly.
