模仿IOS里面的UIActionSheet控件，有IOS6和IOS7两种风格，可以自定义风格，背景图片、按钮图片、文字颜色、间距等。
使用方法
创建一个ActionSheet并显示
ActionSheet.createBuilder(this, getSupportFragmentManager()) .setCancelButtonTitle("Cancel") .setOtherButtonTitles("Item1", "Item2", "Item3", "Item4") .setCancelableOnTouchOutside(true) .setListener(this).show();
方法说明
setCancelButtonTitle()设置取消按钮的标题setOtherButtonTitles()设置条目，String[]setCancelableOnTouchOutside()设置点击空白处关闭setListener()设置事件监听器show()返回ActionSheet对象，可以调用ActionSheet对象的dismiss()方法手动关闭
事件监听
实现ActionSheetListener接口
onOtherButtonClick()点击某个条目，index是条目的下标onCancel取消事件，点击取消按钮，或者点击空白处(setCancelableOnTouchOutside(true))onDismiss()关闭事件
@Override public void onOtherButtonClick(ActionSheet actionSheet, int index) { Toast.makeText(getApplicationContext(), "click item index = " + index, 0).show(); } @Override public void onCancel(ActionSheet actionSheet) { Toast.makeText(getApplicationContext(), "cancel", 0).show(); } @Override public void onDismiss(ActionSheet actionSheet) { Toast.makeText(getApplicationContext(), "dismissed", 0).show(); }
样式
默认的样式非常丑陋，项目中提供了两种Style，可以配置Theme
<!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme"> <item name="actionSheetStyle">@style/ActionSheetStyleIOS6</item> or <item name="actionSheetStyle">@style/ActionSheetStyleIOS7</item> </style>
还可以自定义样式，自定义一个style即可，可以参考ActionSheetStyleIOS6/ActionSheetStyleIOS7的写法
<!-- IOS7样式 --> <style name="ActionSheetStyleIOS7"> <item name="actionSheetBackground">@android:color/transparent</item> <item name="cancelButtonBackground">@drawable/slt_as_ios7_cancel_bt</item> <item name="otherButtonTopBackground">@drawable/slt_as_ios7_other_bt_top</item> <item name="otherButtonMiddleBackground">@drawable/slt_as_ios7_other_bt_middle</item> <item name="otherButtonBottomBackground">@drawable/slt_as_ios7_other_bt_bottom</item> <item name="otherButtonSingleBackground">@drawable/slt_as_ios7_other_bt_single</item> <item name="cancelButtonTextColor">#1E82FF</item> <item name="otherButtonTextColor">#1E82FF</item> <item name="actionSheetPadding">10dp</item> <item name="otherButtonSpacing">0dp</item> <item name="cancelButtonMarginTop">10dp</item> <item name="actionSheetTextSize">12sp</item> </style>
