Change activity background from code

android, android-activity, user-interface, xamarin.android

Solution

first add LinearLayout id as in your layout xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/linearLayoutid" 
android:minWidth="25px"
android:minHeight="25px"
android:background="@drawable/background_fingerboard"

and in code part set background as::

LinearLayout  linearLayout = (LinearLayout) findViewById(R.id.linearLayoutid);
 linearLayout.setBackgroundResource(R.drawable.background_fingerboard);

Problem

I have an activity with a background: ``` <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:minWidth="25px" android:minHeight="25px" android:background="@drawable/background_fingerboard" /> ``` How can I change background image from code? I actually use mono, but Java samples will also be helpful.
