我正在尝试在我的Android应用中使用MAPBOX sdk。我目前正在使用Mapbox 0.3和android sdk 20

然而，当我尝试进入我的布局时，我收到以下错误：

The following classes could not be instantiated:
- com.mapbox.mapboxsdk.views.MapView (Open Class, Show Exception)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when     shown in the IDE

我的android清单中还有以下内容

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test.new31231" >
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MyActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

这是我的build.gradle文件：

    apply plugin: 'com.android.application'
android {
compileSdkVersion 20
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "com.example.test.new31231"
    minSdkVersion 15
    targetSdkVersion 20
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
repositories {
mavenCentral()
}
dependencies {
compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:0.3.0@aar'){
    transitive=true
}
compile ('com.cocoahero.android:geojson:1.0.0@aar'){
    transitive=true
}
}

任何帮助将不胜感激！

我已经解决了它，包括布局的根元素中的以下行

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

如下例所示

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:mapbox="http://schemas.android.com/apk/res-auto"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:background="#00000000"
              android:orientation="vertical">

              <com.mapbox.mapboxsdk.views.MapView
                        android:id="@+id/map"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        mapbox:mapid="username.xxx12345" />

</LinearLayout>
