AndroidUI開源元件庫BottomView 第三方自定義UI控件

實作功能：

可以在底部彈出的View裡自定義布局；

可以自定義是否可以觸摸外部消失；

可以自定義事件；

可以自定義外圍背景是否透明；

可以自定義動畫；

如果需要的話，可以強制為頂部View顯示

其實原理就是WindowManager Dialog 和Animation的組合

這裡分享一個Android的非常經典實用而且簡單友善的第三方UI控件庫：BottomView（小米的米UI也用到了這個）

用法：

1、下載下傳BottomView.jar庫檔案，放到Android項目工程裡的libs裡

2、設定BottomView的Theme：

這2個Theme複制粘貼到你的項目的res/values/styles.xml裡即可

<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>
<style name="BottomViewTheme_Transparent">
<item name="android:backgroundDimEnabled">false</item>
</style>

複制代碼

另外如果提示

<item name="android:windowBackground">@color/white</item>

這裡的white找不到的話，說明你項目res/values/color.xml沒有建立或者沒有white顔色這個值，隻需在res/values/color.xml裡添加

<color name="white">#ffffff</color>

這個白色值即可。

另外View的動畫Theme可選，建議也複制進去，效果好一些，代碼如下：

<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>

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>

res/anim/bottomview_anim_exit.xml

android:toYDelta="100%p" />

整體為：

2、部分核心使用代碼：

BottomView bottomView = new BottomView(this,
R.style.BottomViewTheme_Defalut, R.layout.bottom_view);
bottomView.setAnimation(R.style.BottomToTopAnim);//設定動畫，可選
bottomView.showBottomView(false);

如果想擷取這個View的話，調用.getView()方法即可。
