技术标签: Android开发 android 菜单 menu ios 菜单控件
仿IOS滑动菜单
Date:2015-4-23
SourceCode:https://github.com/FrostySmile/ActionSheetMenu
本文详细介绍类似IOS平台下ActionSheet菜单控件的Android实现全过程,并增加自定义属性。通过本文,你可以学习到以下内容:
IOS6样式:
IOS8样式:
自定义背景:
在attr.xml中定义属性字段。用declare-styleable标签定义属性集合分类baseName,再在内部用attr标签定义具体属性字段名attrName,代码中使用方式则是(R.styleable.baseName_attrName)。代码如下:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-- ActionSheetMenu的主题(ios6和ios7) 属性-->
<declare-styleable name="ActionSheets">
<attr name="actionSheetStyle" format="reference" />
</declare-styleable>
<!-- ActionSheetMenu的具体属性字段 -->
<declare-styleable name="ActionSheet">
<attr name="actionSheetBackground" format="color|reference" /><!-- 整个actionSheet背景 -->
<attr name="actionSheetPadding" format="dimension|reference" /><!-- 整个actionSheet内部间距 -->
<attr name="actionSheetTextSize" format="dimension|reference" /><!-- actionSheet总体字体大小 -->
<attr name = "titleButtonBackground" format="color|reference" /><!-- 标题按钮的背景 -->
<attr name = "titleButtonTextSize" format = "dimension|reference" /><!-- 标题按钮的字体大小 -->
<attr name = "titleButtonTextColor" format = "color|reference" /><!-- 标题字体的颜色 -->
<attr name="titleButtonMarginButton" format="dimension|reference" /><!--标题按钮底部距离 -->
<attr name="titleButtonPadding" format="dimension|reference" /><!--标题按内部间距 -->
<attr name="otherButtonTopBackground" format="color|reference" /><!-- 主按钮顶部按钮背景-->
<attr name="otherButtonMiddleBackground" format="color|reference" /><!-- 主按钮中间按钮背景-->
<attr name="otherButtonBottomBackground" format="color|reference" /><!-- 主按钮底部按钮背景-->
<attr name="otherButtonTextColor" format="color|reference" /><!-- 主按钮字体颜色-->
<attr name="otherButtonSingleBackground" format="color|reference" /><!-- 单个主按钮背景-->
<attr name="otherButtonSpacing" format="dimension|reference" /><!-- 主按钮外部间距 -->
<attr name="cancelButtonBackground" format="color|reference" /><!-- 取消按钮背景-->
<attr name="cancelButtonTextColor" format="color|reference" /><!-- 取消按钮字体颜色-->
<attr name="cancelButtonMarginTop" format="dimension|reference" /><!-- 取消按钮顶部距离 -->
</declare-styleable>
</resources>
在style.xml中自定义样式style,分别为IOS6和IOS7风格。

首先继承Dialog,而不是继承Fragment或者Activity等这样无,实现view的OnClickListener接口。在创建布局(包括面板,item)之前,先要读取使用到的属性(readAttribute方法),将属性值封装到内部类中便于使用。为创建的view设置高宽和ID属性等,然后实现onClick方法,根据点击的view调用回调接口的方法,并传出事件源,具体详情功能见代码注释。
public class JFActionSheetMenu extends Dialog implements OnClickListener{
private Context mContext;
private OnActionSheetItemClickListener mListener;//JFrostyActionSheet回调接口(代理)
private Attributes mAttrs;//JFrostyActionSheet的属性类,从资源文件读取配置
private List<String> itemsText;//item标题

private int titleTextColor;
private boolean isShowTitle = false;//是否显示标题
private String cancelText = "";
private int cancelTextColor;
private boolean mDismissed = true;//是否消失了
private boolean useCustonStyle = false;
private int titleBg;//标题背景
private int itemBg;// 主item背景
private int cancelBg;//取消背景
//Constructor with context
