Question

I am loading images in an ImageView from url. (from RSS feed)

The problem is that the resolution of the loaded image is lower than the original image !!

I searched Stackoverflow and found that the solution is to set the “inScaled” option to false to prevent image re-scaling.
but, this solution didn’t work for me.

Here is the code:

    URL feedImage= new URL(img_link);
    HttpURLConnection conn= (HttpURLConnection)feedImage.openConnection();
    InputStream is = conn.getInputStream();
    BitmapFactory.Options  BFoptions = new BitmapFactory.Options();
    BFoptions.inScaled = false;
    Bitmap img = BitmapFactory.decodeStream(is,null, BFoptions);
    int density = img.getDensity(); Log.e("img", "Image density is " + density);
    int width =img.getWidth(); Log.e("img", "Image width is " + width);
    int height  = img.getHeight(); Log.e("img", "Image height is " + height);

    my_image.setImageBitmap(img);

The variables density, width and height are lower than the original image’s values.

and here is a part of my layout:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">


            <ImageView
                    android:id="@+id/joke_image"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"         
                    android:contentDescription="temp description"/>


            <ScrollView
                    android:id="@+id/SV"
                    android:layout_width="fill_parent"
                    android:layout_height="30dp"
                    android:background="@drawable/background"
                    android:paddingTop="10dp"
                    android:paddingLeft="10dp"
                    android:paddingRight="10dp"
                    android:paddingBottom="50dp">

                    <!-- bla 
                         bla 
                         bla  

                         -->


            </ScrollView>   
</RelativeLayout>

Thanks in advance

Answer 1

Finally it was solved 🙂

It appeared to be not related to the code or the ImageViews, …..

All the images in the RSS feeds are thumbnails … which is the reason that they appear small in the app but large in the website.

So the solution was to replace the “_s.jpg” at the end of each image’s url with “_n.jpg” 🙂

I hope this answer will help someone else 🙂
