android：底部背景阴影的dialog弹出
style 样式：
<style name="BottomDialog">
<item name="android:windowNoTitle">true
<item name="android:windowIsFloating">true
<item name="android:windowEnterAnimation">@anim/push_bottom_in
<item name="android:windowExitAnimation">@anim/push_bottom_out
<item name="android:windowContentOverlay">@null
</style>
关键在于Theme.Dialog中的各种属性：
<style name="Theme.Dialog" parent="Theme.AppCompat.Light.Dialog">
<item name="windowActionBar">false</item>
<!-- 没有标题栏 -->
<item name="windowNoTitle">true</item>
<!--边框-->
<item name="android:windowFrame">@null</item>
<!--是否浮现在activity之上-->
<item name="android:windowIsFloating">true</item>
<!-- 是否透明 -->
<item name="android:windowIsTranslucent">true</item>
<!--除去title-->
<item name="android:windowNoTitle">true</item>
<!-- 对话框是否有遮盖 -->
<item name="android:windowContentOverlay">@null</item>
<!-- 对话框出现时背景是否变暗 -->
<item name="android:backgroundDimEnabled">true</item>
<!-- 背景颜色，因为windowBackground中的背景已经写死了，所以这里的设置无效 -->
<item name="android:colorBackground">@color/background_floating_material_light</item>
<!-- 着色缓存（一般不用）-->
<item name="android:colorBackgroundCacheHint">@null</item>
<!-- 标题的字体样式 -->
<item name="android:windowTitleStyle">@style/RtlOverlay.DialogWindowTitle.AppCompat</item>
<item name="android:windowTitleBackgroundStyle">@style/Base.DialogWindowTitleBackground.AppCompat</item>
<!--对话框背景(重要) , default = abc_dialog_material_background-->
<item name="android:windowBackground">@drawable/dialog_bg_custom</item>
<!-- 动画 -->
<item name="android:windowAnimationStyle">@style/Animation.AppCompat.Dialog</item>
<!-- 输入法弹出时自适应 -->
<item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
<item name="windowActionModeOverlay">true</item>
<!-- 列表部分的内边距，作用于单选、多选列表 -->
<item name="listPreferredItemPaddingLeft">20dip</item>
<item name="listPreferredItemPaddingRight">24dip</item>
<item name="android:listDivider">@null</item>
<!-- 单选、多选对话框列表文字的颜色 默认：@color/abc_primary_text_material_light -->
<item name="textColorAlertDialogListItem">#00ff00</item>
<!-- 单选、多选对话框的分割线 -->
<!-- dialog中listView的divider 默认：@null-->
<item name="listDividerAlertDialog">@drawable/divider</item>
<!-- 单选对话框的按钮图标 (默认不为null)-->
<item name="android:listChoiceIndicatorSingle">@android:drawable/btn_radio</item>
<!-- 对话框整体的内边距，但不作用于列表部分 默认：@dimen/abc_dialog_padding_material-->
<item name="dialogPreferredPadding">20dp</item>
<item name="alertDialogCenterButtons">true</item>
<!-- 对话框内各个布局的布局文件-->
<item name="alertDialogStyle">@style/AlertDialogStyle</item>
</style>
