Android studio xml介面無法預覽問題
如下圖

修改style.xml中的
parent=“Theme.AppCompat.Light.DarkActionBar”
改為
parent=“Base.Theme.AppCompat.Light.DarkActionBar”

 <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
