最近集成chromcast 到项目里，总是在不停的报错，后来发现我theme用的不对，要得用
Theme.AppCompat 下面的theme, 之前我的activity 用的是 @android:style/Theme.NoTitleBar，
我也看了源码，这估计是因为inflate在加载xml的时候，用不同的theme来画view,然后不同的theme 有不同的写法
正确的theme
<style name="AppThemeCast"
parent="Theme.AppCompat.NoActionBar">
<!-- Set AppCompat’s color theming attrs -->
<item name="colorPrimary">@color/white</item>
<item name="colorPrimaryDark">@color/black</item>
<item name="colorAccent">@color/gray</item>
<item name="android:textColorPrimary">@color/white</item>
<item name="android:textColorSecondary">@color/black</item>
<item name="windowNoTitle">true</item>
<!-- The rest of your attributes -->
<!--item name="android:seekBarStyle">@style/YellowSeekBar</item-->
</style>
Caused by: java.lang.IllegalArgumentException: background can not be translucent: #0
