    xmlns:tools="http://schemas.android.com/tools"

xml version="1.0" encoding="utf-8"?>  
<LinearLayout xmlns:androclass="http://schemas.android.com/apk/res/android"  
      android:id="@+id/custom_toast_layout"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    android:orientation="vertical"  
    android:background="#F14E23"  
     >  
       
    <ImageView  
        android:id="@+id/custom_toast_image"  
        android:layout_width="wrap_content"  
        android:layout_height="wrap_content"  
        android:contentDescription="@string/hello_world"  
        android:src="@drawable/ic_launcher"/>  
      
<TextView  
        android:id="@+id/custom_toast_message"  
        android:layout_width="wrap_content"
