用於前棒棒糖和棒棒糖設備的材料設計顏色不起作用

Question

我嘗試在Pre-Lollipop設備上運行我的應用程序。但是，這段代碼給我展示了Pre-Lolliop和棒棒糖設備的相同錯誤。
如果我將「android：」添加到樣式21中的樣式中，棒棒糖設備可以正常工作，但會顯示一些像android：color要求Android lvl 21（當前Api lvl爲17）的錯誤。

Answer 1

使用Android：colorPrimary。如果您從Theme.AppCompat繼承，colorPrimary將僅適用於它。覆蓋值-v21中的所有主題。

<style name="AppTheme.Base" parent="android:Theme.Material"> 
    <item name="colorPrimary">@color/primary</item> 
    <item name="colorPrimaryDark">@color/primary_dark</item> 
    <item name="colorAccent">@color/accent</item> 
    <item name="textColor">@color/primary_dark</item> 
    <item name="editTextColor">@color/primary_dark</item> 
    <item name="textColorPrimary">@color/icons</item> 
    <item name="imageButtonStyle">@color/icons</item> 
</style> 

Answer 2

colorPrimary，colorPrimaryDark和colorAccent不撒謊的 '機器人' 命名空間。但是，其餘的人躺在android命名空間中。所以，你的風格（正常和v21）應該是這樣的：

<style name="AppTheme.Base" parent="@style/Theme.AppCompat.Light.NoActionBar"> 
     <item name="colorPrimary">@color/primary</item> 
     <item name="colorPrimaryDark">@color/primary_dark</item> 
     <item name="colorAccent">@color/accent</item> 
     <item name="android:textColor">@color/primary_dark</item> 
     <item name="android:editTextColor">@color/primary_dark</item> 
     <item name="android:textColorPrimary">@color/icons</item> 
     <item name="android:imageButtonStyle">@color/icons</item> 
    </style>
