I'm trying to create an activity that display an image that is obtained from an url. I want the width of the image to adapt the screen but the height of the image can be longer than the screen so that the image becomes scrollable (vertically). First of all, I displayed the image from a drawable folder and it worked with the following code :

<ScrollView android:layout_width="fill_parent" android:id="@+id/scrollView1" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_alignParentLeft="true" android:layout_alignParentRight="true" android:scrollbarAlwaysDrawVerticalTrack="true"> <LinearLayout android:id="@+id/linearLayout1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_horizontal">

    <ImageView
        android:src="@drawable/programme"
        android:layout_height="wrap_content"
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:scaleType="fitStart"></ImageView>
</LinearLayout>
</ScrollView>
But now I wanted the image to charge from an URL so I used the ion library :
Ion.with(imageView)
        .load("http://...");
The image load but it is no longer scrollable and doesn't display as wanted.
Do you have any solution? Thanks
      
In your LinearLayout you need width with "match_parent".
Let your "activity_what.xml" like this.
See the demo below.
      
Thanks for the answer. I didn't copy the full code code but I've already done that and it doesn't seems to work...
<ScrollView
    android:layout_width="fill_parent"
    android:id="@+id/scrollView1"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:scrollbarAlwaysDrawVerticalTrack="true">
    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal">
    <ImageView
        android:src="@drawable/programme"
        android:layout_height="wrap_content"
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:scaleType="fitStart"></ImageView>
</LinearLayout>
</ScrollView>
