How to Add Background Image in Android Studio
7 Answers 7
use the android:background attribute in your xml. Easiest way if you want to apply it to a whole activity is to put it in the root of your layout. So if you have a RelativeLayout as the start of your xml, put it in here:
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/rootRL" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/background"> </RelativeLayout>

You can set the "background image" to an activity by setting android:background xml attributes as followings:
(Here, for example, Take a LinearLayout for an activity and setting a background image for the layout(i.e. indirectly to an activity))
<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android" android:background="@drawable/icon"> </LinearLayout> answered Jul 22 '10 at 8:53

I've noticed that doing this works fine for a LinearLayout, but for RelativeLayouts, I get OOM errors. I've read plenty of decodeBitmap posts or layout.invalidate() posts, or Bitmap.recycle posts, etc...How would you persist an image as the background of the app using RelativeLayouts? Should I be caching any image that will appear in more than one activity? What is the best practice?

Nowadays we have to use match_parent :
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:background="@drawable/background"> </RelativeLayout>

We can easily place the background image in PercentFrameLayout using the ImageView. We have to set the scaleType attribute value="fitXY" and in the foreground we can also display other view's like textview or button.
<android.support.percent.PercentFrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" xmlns:app="http://schemas.android.com/apk/res-auto" > <ImageView android:src="@drawable/logo" android:id="@+id/im1" android:scaleType="fitXY" android:layout_height="match_parent" android:layout_width="match_parent"/> <EditText android:layout_gravity="center_horizontal" android:hint="Enter Username" android:id="@+id/et1" android:layout_height="wrap_content" app:layout_widthPercent="50%" app:layout_marginTopPercent="30%" /> <Button android:layout_gravity="center_horizontal" android:text="Login" android:id="@+id/b1" android:layout_height="wrap_content" app:layout_widthPercent="50%" app:layout_marginTopPercent="40%"/> </android.support.percent.PercentFrameLayout> answered May 20 '17 at 9:42

This can, unfortunately, cause some problems...sure it will work for your main activity, but if you open a new activity with the same android:background="@drawable/background", as soon as you rotate the emulator in most cases, and some devices, you will crash with an "Out of Memory.." error if your bgImg is a high resolution. @Sephy, how would you handle this issue?
