实现功能:
可以在底部弹出的View里自定义布局;
可以自定义是否可以触摸外部消失;
可以自定义事件;
可以自定义外围背景是否透明;
可以自定义动画;
如果需要的话,可以强制为顶部View显示

其实原理就是WindowManager Dialog 和Animation的组合
这里分享一个Android的非常经典实用而且简单方便的第三方UI控件库:BottomView(小米的米UI也用到了这个)
实现功能:
可以在底部弹出的View里自定义布局;
可以自定义是否可以触摸外部消失;
可以自定义事件;
可以自定义外围背景是否透明;
可以自定义动画;
如果需要的话,可以强制为顶部View显示
用法:
1、下载BottomView.jar库文件,放到Android项目工程里的libs里
2、设置BottomView的Theme:
这2个Theme复制粘贴到你的项目的res/values/styles.xml里即可
- <!--半透明背景Theme-->
- <style name="BottomViewTheme_Defalut">
- <item name="android:windowFrame">@null</item>
- <item name="android:windowContentOverlay">@null</item>
- <item name="android:windowIsFloating">true</item>
- <item name="android:windowIsTranslucent">false</item>
- <item name="android:windowNoTitle">true</item>
- <item name="android:windowBackground">@color/white</item>
- <item name="android:backgroundDimEnabled">true</item>
- <item name="android:windowFullscreen">true</item>
- </style>
- <!--透明背景Theme-->
- <style name="BottomViewTheme_Transparent">
- <item name="android:windowFrame">@null</item>
- <item name="android:windowIsFloating">true</item>
- <!-- Transparent -->
- <item name="android:windowIsTranslucent">false</item>
- <item name="android:windowContentOverlay">@null</item>
- <item name="android:windowNoTitle">true</item>
- <item name="android:windowBackground">@color/white</item>
- <item name="android:backgroundDimEnabled">false</item>
- </style>
复制代码
另外如果提示
- <item name="android:windowBackground">@color/white</item>
复制代码
这里的white找不到的话,说明你项目res/values/color.xml没有新建或者没有white颜色这个值,只需在res/values/color.xml里添加
- <color name="white">#ffffff</color>
复制代码
这个白色值即可。
另外View的动画Theme可选,建议也复制进去,效果好一些,代码如下:
- <font color="#333333"><font face="Arial"> <style name="BottomToTopAnim" parent="android:Animation">
- <item name="@android:windowEnterAnimation">@anim/bottomview_anim_enter</item>
- <item name="@android:windowExitAnimation">@anim/bottomview_anim_exit</item>
- </style></font></font>
复制代码
res/anim/bottomview_anim_enter.xml
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android" >
- <translate
- android:duration="500"
- android:fromYDelta="100%p" />
- </set>
复制代码
res/anim/bottomview_anim_exit.xml
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android" >
- <translate
- android:duration="500"
- android:toYDelta="100%p" />
- </set>
复制代码
整体为:
2、部分核心使用代码:
- BottomView bottomView = new BottomView(this,
- R.style.BottomViewTheme_Defalut, R.layout.bottom_view);
- bottomView.setAnimation(R.style.BottomToTopAnim);//设置动画,可选
- bottomView.showBottomView(false);
复制代码
如果想获取这个View的话,调用.getView()方法即可。
效果图之一:(可随意发挥)
