You have at least 3 problems. First is for loop in getView. You get "position" attribute in getView method for which you should return ImageView (just one!). Now you always load all images and then return last.
Second problem is using Drawable,createFromStream method. This is a buggy method, check here: http://stackoverflow.com/questions/4601352/createfromstream-in-android-returning-null-for-certain-url Trird problem is that you are doing network operations on UI thread, I would rather use one of these two libraries: - https://github.com/nostra13/Android-Universal-Image-Loader - https://github.com/DHuckaby/Prime On Tuesday, August 7, 2012 3:28:52 PM UTC+2, Mohamed Naguib wrote: > > I am trying to create a gridview and load some images from URLs to this > gridview but there is an issue in loading images but i can't find it, can > anyone help ? > > package com.images; > import java.io.InputStream; > import java.net.URL; > > import android.content.Context; > import android.graphics.drawable.Drawable; > import android.view.View; > import android.view.ViewGroup; > import android.widget.BaseAdapter; > import android.widget.GridView; > import android.widget.ImageView; > > import com.coboltforge.slidemenuexample.MainActivity; > import com.coboltforge.slidemenuexample.R; > > public class ImageAdapter extends BaseAdapter { > private Context mContext; > > // Keep all Images in array > public Integer[] mThumbIds = new Integer [27]; > > // Constructor > public ImageAdapter(Context c) { > mContext = c; > } > > @Override > public int getCount() { > return mThumbIds.length; > } > > @Override > public Object getItem(int position) { > return mThumbIds[position]; > } > > @Override > public long getItemId(int position) { > return 0; > } > > @Override > public View getView(int position, View convertView, ViewGroup parent) { > /* > * ImageView imageView = new ImageView(mContext); > * imageView.setImageResource(mThumbIds[position]); > * imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); > * imageView.setLayoutParams(new GridView.LayoutParams(130, 130)); > * return imageView; > */ > ImageView imageView; > if (convertView == null) { > imageView = new ImageView(mContext); > imageView.setLayoutParams(new GridView.LayoutParams(150, 150)); > imageView.setAdjustViewBounds(false); > imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); > imageView.setPadding(8, 8, 8, 8); > } else { > imageView = (ImageView) convertView; > } > for (int i = 0; i < MainActivity.presentersImages.size(); i++) { > imageView > > .setImageDrawable(LoadImageFromWebOperations(MainActivity.presentersImages > .get(i) + position)); > > } > return imageView; > } > > protected Drawable LoadImageFromWebOperations(String url) { > try { > InputStream is = (InputStream) new URL(url).getContent(); > Drawable d = Drawable.createFromStream(is, "src name"); > return d; > } catch (Exception e) { > System.exit(0); > return null; > } > } > } > MainActivity.presentersImages is an ArrayList of strings contains the url > for the images > > -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
