android popupwindow 对话框 添加外框 并修改

1. 添加外款的方法 是 画一个 sharp 然后设置成背景 

    sharp.xml 文件 内容如下

    <?xml version="1.0" encoding="utf-8"?>  
<shape xmlns:android="http://schemas.android.com/apk/res/android">  
    <solid android:color="#404040" />  
    <stroke android:width="1dp" android:color="#BBBBBB" />  
     <corners android:radius="6dp" />
    <padding android:left="5dp" android:top="5dp" android:right="5dp" android:bottom="5dp" />  
</shape> 

2. sharp.xml 和 popupwindow 关联

    View dialogView;

  LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);  
  dialogView = inflater.inflate(R.layout.statusbox, null, false);
  dialogView.setBackgroundResource(R.layout.statusbox_shape);  //关联 popupwindow 和  sharp.xml
  popupWindow = new PopupWindow(dialogView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, true);//创建PopupWindow实例
