I'm having the following problem;
I have a LinearLayout with in it a ScrollView, in the ScrollView is some custom view. Now I want to put an image in the background of the LinearLayout and keep the image in its original size. But when I set the background property of the LinearLayout it stretches to fit the full screen. How can I make it so that the image keeps its original size?
My xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/some_drawable">
<ScrollView
android:id="@+id/scrollview"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:fillViewport="true">
<some.custom.layout
android:id="@+id/mainLayout"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
</ScrollView>
</LinearLayout>
Try using FrameLayout with an ImageView and LinearLayout inside. For example, try changing the alpha of the image and move it to foreground in your FrameLayout, thus the LinearLayout stays on background. Hope this helps!
