Question

我正在尝试使用ArcGis android sdk开发离线地图应用程序。遵循ArcGis网站上的教程。因为它是一个离线地图应用程序，我正在测试它没有互联网连接。但是，当我运行应用程序时，MapView为空。它只是显示黑屏。当我检查Logcat时，它说

11-26 14:39:57.757 28520-28520/com.example.lalprakash.offlinearcgismap D/GLSurfaceView: checkGLSurfaceViewlLogProperty get invalid command

R.....ID 0,0-0,0}

我无法理解从server.arcgisonline.com到public class MainActivity extends Activity { MapView mMapView; String extern = Environment.getExternalStorageDirectory().getPath(); final String tpkPath = "/ArcGIS/samples/OfflineRouting/ImageryTPK.tpk"; TiledLayer mTileLayer; GraphicsLayer mGraphicsLayer = new GraphicsLayer(GraphicsLayer.RenderingMode.DYNAMIC); RouteTask mRouteTask = null; NAFeaturesAsFeature mStops = new NAFeaturesAsFeature(); Locator mLocator = null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTileLayer = new ArcGISLocalTiledLayer(extern + tpkPath); // Retrieve the map and initial extent from XML layout mMapView = (MapView) findViewById(R.id.map); // Set the tiled map service layer and add a graphics layer mMapView.addLayer(mTileLayer); mMapView.addLayer(mGraphicsLayer); } }的请求。我的java文件和xml文件如下

MainActivity.java

<RelativeLayout 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">

    <com.esri.android.map.MapView
        android:id="@+id/map"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        initExtent = "-1.3296373526814876E7 3930962.41823043 -1.2807176545789773E7 4201243.7502468005"
        mapoptions.MapType="Topo"
        mapoptions.ZoomLevel="16" />
</RelativeLayout>

activity_main.xml中

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        applicationId "com.example.lalprakash.offlinearcgismap"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        sourceSets.main{
            jniLibs.srcDir 'src/main/jni'
            jni.srcDirs=[]
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile files('libs/arcgis-android-api.jar')
    compile files('libs/arcgis-android-app-toolkit.jar')
    compile files('libs/jackson-all-1.9.0.jar')
}

和 build.gradle 如下

tpk

另外，我已将{{1}}文件放在内部存储器的根目录中。请帮助我，因为我非常需要它。谢谢。

你可以从你的XML中删除initextent和mapoption.maptype并告诉我会发生什么。我没有机会看看你的堆栈跟踪，但这应该在你的屏幕上显示你的地图
