Android - 无法使用 ListFragement 设置 LIstView 背景颜色

Question

我创建了一个colors.xml并有一个list_fragment.xml如下，listView的背景颜色没有变成蓝色？

colors.xml

           <?xml version="1.0" encoding="utf-8"?>
               <resources>
                  <color name="colorPrimary">#008577</color>
                  <color name="colorPrimaryDark">#00574B</color>
                  <color name="colorAccent">#D81B60</color>
                  <color name="orange">#ff5500</color>
                  <color name="transparent">#00000000</color>
                  <color name="black">#000000</color>
                  <color name="gray">#999999</color>
                  <color name="blue">#0066cc</color>
            </resources>

list_fragment.xml

        <?xml version="1.0" encoding="utf-8"?>
        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         xmlns:tools="http://schemas.android.com/tools"
         android:orientation="vertical"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         tools:context=".HomePageListFragment">


       <ListView
         android:id="@android:id/list"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:background="@color/blue"
       </ListView>

     </LinearLayout>enter code here

您的 XML 格式不正确：

  <ListView
     android:id="@android:id/list" <=== change it to android:id="@+id/list"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:background="@color/blue"  <=== missing ">" to close the tag
   </ListView>
