1. Make a class like this:

   public class CustomDialog extends Dialog {
       public AlertFinishiView(Context context) {
           super(context);
           requestWindowFeature(Window.FEATURE_NO_TITLE);
           setContentView(R.layout.dialog);
           getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
       }
   }

   <?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:background="@android:color/transparent">
   
      <RelativeLayout 
         android:layout_width="220dp" 
         android:layout_height="140dp" 
         android:layout_centerHorizontal="true" 
         android:layout_centerVertical="true"            
         android:background="@drawable/bg_custom_dialog" >
   
         <Button android:id="@+id/button1" 
            android:layout_width="wrap_content"

Use this, It works perfectly;

             dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); //before     
             dialog.setContentView(R.layout.your_dialog_layout);
