android - 错误解析 :unbound prefix exception

Question

此代码显示未绑定(bind)异常，我尝试了所有组合..无法解决!!

    <com.google.android.maps:MapView
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"       
     android.apikey="AIzaSyDIqLvjKi_VM7nT1DUSTzIeKDTuzPGFqrQ"/>

整个代码是:

    <?xml version="1.0" encoding="utf-8"?>
     <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" >  
     <com.google.android.maps:MapView
      android:id="@+id/map1"    
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"    
      android:apikey="AIzaSyDIqLvjKi_VM7nT1DUSTzIeKDTuzPGFqrQ"/>
     </RelativeLayout>

Answer 1

你需要这个

 xmlns:android="http://schemas.android.com/apk/res/android"

在您的 xml 根元素中

    <?xml version="1.0" encoding="utf-8"?>
     <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" >  
     <com.google.android.maps.MapView // :MapView is .MapView
      android:id="@+id/map1"    
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"/>    
     </RelativeLayout>

还有

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="api key"/>
// android.apikey

必须在manifest文件的application标签中

你可以找到一个例子

Android - android.view.InflateException: Binary XML file line #8: Error inflating class fragment
