Question

I am using Android 2.2. I am trying following code to run:

Uri uri=Uri.parse("http://bluediamondring-s.com/wp-content/uploads/2010/08/gold-ring.jpg");
File f=new File(uri.getPath());
image.setImageURI(Uri.parse(f.toString()));
image.invalidate();

But image is not visible on my android screen.

suggest something.

Answer 1

let me give you an method
utils

public class AsyncUploadImage extends AsyncTask<Object, Object, Object> {
private static final String TAG = "AsyncUploadImage ";
ImageView iv;
private HttpURLConnection connection;
private InputStream is;
private Bitmap bitmap;
public AsyncUploadImage(ImageView mImageView) {
    iv = mImageView;
}
@Override
protected Object doInBackground(Object... params) {
    URL url;
    try {
        url = new URL((String) params[0]);
        connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();
        is = connection.getInputStream();
        bitmap = BitmapFactory.decodeStream(is);
        is.close();
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (is != null) {
                is.close();
            }
            if (connection != null) {
                connection.disconnect();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return bitmap;
}
@Override
protected void onPostExecute(Object result) {
    super.onPostExecute(result);
    if (null != result) {
        iv.setImageBitmap((Bitmap) result);
        Log.i(TAG, "image download ok！！！");
    }else {
        iv.setBackgroundResource(R.drawable.shuben1);
        Log.i(TAG, "image download false！！！");
    }
}

}

when adapter to use

like this

new AsyncUploadImage(itemIcon).execute("http://temp/file/book/images/1325310017.jpg");

//http://temp/file/book/images/1325310017.jpg -> (this is your image url..)
