Android App的背景图片

Question

I am an amateur android programmer and I am trying to stylize my app. I found a picture from the internet, here is the link . I want to set that as my background on the application. I would I do so. I really don't understand the concept of @drawable/background, how does it work, what can I do?

Answer 1

Set your picture into res/drawable folder. Then in your Layout file ( layout/main.xml ) high problably for your default project add this image view

<ImageView
    android:id="@+id/myImageView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentLeft="true"
    android:scale_type="center_crop"
    android:layout_alignParentTop="true" android:src="@drawable/your_picture_name"/>

BUT DON'T ADD YOUR PICTURE'S FILE EXTENTION. ONLY FILE NAME. FOR EXAMPLE IF YOUR PICTURE FULL NAME BEATIFULL_CAR .JPG ONLY ADD BEATIFULL_CAR

Answer 2

1. Drawable is a resource folder in your Android Project where you can past different data.

2. If you want to use any image as a background copy/past it in the Drawable folder and use the attribute android:background="@drawable/your_image_name" in your layout_main.xml as

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/your_picture_name" android:gravity="center_vertical|center_horizontal"

Thats it.
