Android bitmap image size in XML
Only API 23 or later
Just use
<item
android:width="200dp"
android:height="200dp"
android:drawable="@drawable/splash_background"
android:gravity="center" />
instead
<item
android:left="200dp"
android:right="200dp">
<bitmap
android:src="@drawable/splash_background"
android:gravity="center" />
</item>
Although there is no width and height parameters for bitmap, you can set bitmap size using gravity and item width/height.
<item
android:width="230dp"
android:height="70dp">
<bitmap
android:gravity="fill_horizontal|fill_vertical"
android:src="@drawable/screen" />
</item>
You can set item width and height and scale bitmap inside of it using gravity.
I know this is old question but maybe someone will find it useful.
WARNING:
As already mentioned in comments, this method ONLY works with API level 23 (Android 6.0) and up.
