自定义dialog都有自己的主题和动画效果，比如说登录提示框里面有个进度条，提示框的背影透明，dialog没有标题等，这些都需要在style中定义。

**Dialog的风格主题有：**

<style name="MyDialog" parent="android:style/Theme.Dialog">
            
            <item name="android:windowBackground">@android:color/transparent</item>
            
            <item name="android:windowNoTitle">true</item>
            
            <item name="android:windowFrame">@null</item>
            
            <item name="android:windowIsFloating">true</item>
            
            <item name="android:backgroundDimEnabled">false</item>
        </style>

**Dialog 的背景样式：**

可以自己设置颜色，角度等

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
    
        <solid android:color="#ffffff" />
        
        <corners android:radius="6dp" />
    
    </shape>

#### CustomDialog源代码： ####

public class CustomDialog extends Dialog{ 
    
        //自定义dialog
    
        public CustomDialog(Context context,int layout,int style) {
            this(context, WindowManager.LayoutParams.WRAP_CONTENT,WindowManager.LayoutParams.WRAP_CONTENT,layout,style, Gravity.CENTER);
        }
    
        public CustomDialog(Context context,int width,int height,int layout,int style,int gravity,int anim){
            super(context,style);
            //设置leyour
            setContentView(layout);
            //获取window
            Window window=getWindow();
            //获取window属性
            WindowManager.LayoutParams layoutParams=window.getAttributes();
            //修改属性
            layoutParams.width=width;
            layoutParams.height=height;
            layoutParams.gravity=gravity;
            //将属性重新设置
            window.setAttributes(layoutParams);
            //设置动画
            window.setWindowAnimations(anim);
        }
    
        //实例
        public CustomDialog(Context context,int width,int height,int layout,int style,int gravity){
            this(context,width,height,layout,style,gravity,R.style.pop_anim_style);
