android - 在 android studio 中安装 Mapbox 的问题

Question

您好，我尝试将 Map Box 与 Android Studio 结合使用来学习如何构建 GIS 应用程序。我遵循本教程，https://www.mapbox.com/install/android/但是当我尝试测试安装或一些示例时，我收到以下错误。

Android resource compilation failed Output: C:\Users\Vassilis\AndroidStudioProjects\mapBox_test_nbg\app\src\main\res\layout\activity_main.xml:3: error: duplicate attribute.

Command: C:\Users\Vassilis.gradle\caches\transforms-1\files-1.1\aapt2-3.2.1-4818971-windows.jar\efd9526a9f78532313c282340621c36b\aapt2-3.2.1-4818971-windows\aapt2.exe compile --legacy \ -o \ C:\Users\Vassilis\AndroidStudioProjects\mapBox_test_nbg\app\build\intermediates\res\merged\debug \ C:\Users\Vassilis\AndroidStudioProjects\mapBox_test_nbg\app\src\main\res\layout\activity_main.xml Daemon: AAPT2 aapt2-3.2.1-4818971-windows Daemon #2

activity_main.xml的代码是:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.mapbox.mapboxsdk.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        mapbox:mapbox_cameraTargetLat="40.73581"
        mapbox:mapbox_cameraTargetLng="-73.99155"
        mapbox:mapbox_cameraZoom="11"
        mapbox:mapbox_styleUrl="mapbox://styles/mapbox/streets-v11"
        tools:layout_editor_absoluteX="0dp"
        tools:layout_editor_absoluteY="0dp" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

也许这张图片帮助更多

Answer 1

您必须更改 mapbox_styleUrl 值。

mapbox:mapbox_styleUrl="@string/mapbox_style_mapbox_streets"

代替

 mapbox:mapbox_styleUrl="mapbox://styles/mapbox/streets-v11"

但是这种风格的 MapBox for streets-v10 和 v11 目前在 android 上不可用。

同时将此属性添加到您的 mapBox xml

 app:layout_constraintEnd_toEndOf="parent"
 app:layout_constraintTop_toTopOf="parent"
 app:layout_constraintStart_toStartOf="parent"
 app:layout_constraintBottom_toBottomOf="parent"

最后你的 mapbox 必须是这样的

<com.mapbox.mapboxsdk.maps.MapView
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        mapbox:mapbox_cameraTargetLat="40.73581"
        mapbox:mapbox_cameraTargetLng="-73.99155"
        mapbox:mapbox_cameraZoom="11"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        mapbox:mapbox_styleUrl="@string/mapbox_style_mapbox_street1"
        />
