Add a background image to shape in XML Android

问题

How do you add a background image to a shape? The code I tried below but no success:

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<shape xmlns:android=\"http://schemas.android.com/apk/res/android\"
android:shape=\"rectangle\" android:padding=\"10dp\">
//here is where i need to set the image
<solid android:color=\"@drawable/button_image\"/>
    <corners
     android:bottomRightRadius=\"5dp\"
     android:bottomLeftRadius=\"5dp\"
     android:topLeftRadius=\"5dp\"
     android:topRightRadius=\"5dp\"/>
 </shape>

Use following layerlist:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle" android:padding="10dp">
            <corners
                 android:bottomRightRadius="5dp"
                 android:bottomLeftRadius="5dp"
                 android:topLeftRadius="5dp"
                 android:topRightRadius="5dp"/>
         </shape>
   </item>
   <item android:drawable="@drawable/image_name_here" />
</layer-list>

I used the following for a drawable image with a circular background.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/colorAccent"/>
        </shape>
    </item>
    <item
        android:drawable="@drawable/ic_select"
        android:bottom="20dp"
        android:left="20dp"
        android:right="20dp"
        android:top="20dp"/>
</layer-list>

Here is what it looks like

Hope that helps someone out.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ok_icon"/>
    <item>
        <shape
                android:shape="oval">
            <solid android:color="@color/transparent"/>
            <stroke android:width="2dp" android:color="@color/button_grey"/>

I used the following for a drawable image with a border.

First make a .xml file with this code in drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="oval">
        <solid android:color="@color/orange"/>
    </shape>
</item>
<item
    android:top="2dp"
    android:bottom="2dp"
    android:left="2dp"
    android:right="2dp">
    <shape android:shape="oval">
        <solid android:color="@color/white"/>
    </shape>
</item>
<item
    android:drawable="@drawable/messages" //here messages is my image name, please give here your image name.
    android:bottom="15dp"
    android:left="15dp"
    android:right="15dp"
    android:top="15dp"/>

Second make a view .xml file in layout folder and call the above .xml file with this way

<ImageView
   android:id="@+id/imageView2"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@drawable/merchant_circle" />  // here merchant_circle will be your first .xml file name

Here is another most easy way to get a custom shape for your image (Image View). It may be helpful for someone. It's just a single line code.

First you need to add a dependency:

dependencies {
    compile 'com.mafstech.libs:mafs-image-shape:1.0.4'   
}

And then just write a line of code like this:

Shaper.shape(context, 
       R.drawable.your_original_image_which_will_be_displayed, 
       R.drawable.shaped_image_your_original_image_will_get_this_images_shape,
       imageView,
       height, 
       weight);
