效果图如下：

简单的写了个对话框的代码，以便以后复习，那样也方便

activity_main:

自定义对话框的布局activity_myview：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <ImageView         android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/a1"        android:layout_gravity="center_horizontal"/>    <TextView         android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="还能不能愉快的玩耍了"        android:textColor="#33cc33"        android:textSize="25sp"        android:layout_gravity="center_horizontal"/>    <RelativeLayout         android:layout_width="wrap_content"        android:layout_height="wrap_content">        <Button             android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="能"            android:textSize="20sp"            android:layout_alignParentLeft="true"            android:layout_marginLeft="20dp"            android:background="@drawable/btn_selector"            />        <Button             android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:textSize="20sp"            android:text="不能"            android:layout_alignParentRight="true"            android:layout_marginRight="20dp"            android:background="@drawable/btn_selector"/>    </RelativeLayout></LinearLayout>
