How do I make a background image fit the view but keep its aspect ratio when using <bitmap />
as a background drawable XML?
None of <bitmap>
's android:gravity
values gives the desired effect.
It is impossible to achieve manipulating background attribute within xml-files only. There are two options:
You cut/scale the bitmap programmatically with
Bitmap.createScaledBitmap(Bitmap src, int dstWidth, int dstHeight, boolean filter)
and set it as some View
's background.
You use ImageView
instead of background placing it as the first layout's element and specify android:scaleType
attribute for it:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/background"
android:scaleType="centerCrop" />
...
