Android shape background

问题:

Is it possible to draw a shape in xml, and use a png as the background to that shape? I already have the shape (it's a square with rounded corners), and i would like to put a background to that square.

Yes you can use any shape file as background for any view. This sample create rounded background with white color and black border around the shape.

Sample :

rounded_corner.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <corners
        android:bottomLeftRadius="10dp"
        android:bottomRightRadius="10dp"
        android:topLeftRadius="10dp"
        android:topRightRadius="10dp" />

    <stroke
        android:width="0.5dp"
        android:color="@color/color_grey" />

    <solid android:color="@color/color_white" />

</shape>

u can use this as,

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_gravity="center_horizontal"
    android:background="@drawable/rounded_corner"
    android:orientation="vertical" >
