I use Layout_width="fill_parent
" and Layout_height="wrap content"
. If an image is bigger than the ImageView, it will be downscaled perfectly.
However, I never got it working to upscale smaller images. I tried any combination of ScaleType and "AdjustViewBounds": it always stays in its own size in the middle of the image view. Here is the code...
<LinearLayout
android:id="@+id/LinearLayout02"
android:layout_height="wrap_content"
android:background="@drawable/content_bg"
android:orientation="vertical"
android:padding="5dp"
android:layout_width="fill_parent"
android:layout_marginLeft="1px">
<ImageView
android:layout_height="wrap_content"
android:src="@drawable/test"
android:id="@+id/ImageViewTest"
android:layout_width="fill_parent"
android:adjustViewBounds="true"
android:scaleType="center"></ImageView>
</LinearLayout>
I just found a way to make it work.
This works in 2.1(AVD) & 4.1.2(device)
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitCenter" />
</LinearLayout>
