我在一个模块(arcgislibrary)中使用ArcGis库10.2.29,在MainActivity中,我需要在该模块中使用这些类。因此,在Module中,我创建了一个MapViewExt文件,该文件扩展了ArcGis的MapView:
public class MapViewExt extends MapView {
private Context ctx;
private GraphicsLayer gLayer;
private static ArrayList<Point> allPoints;
private static ArrayList<Point> selectedPoints;
public MapViewExt(Context context, AttributeSet attrs) {
super(context,attrs);
this.ctx=context;
InitializeMap();
}
private void InitializeMap() {
setEsriLogoVisible(true);
enableWrapAround(true);
gLayer=new GraphicsLayer();
addLayer(gLayer);
}
}
这是模块的毕业文件:
apply plugin: 'com.android.library'
android {
compileSdkVersion 28
defaultConfig {
minSdkVersion 26
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.esri.arcgis.android:arcgis-android:10.2.9'
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
应用程序模块的成绩文件,其中MainActivity为:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.my.domain.arcgislib"
minSdkVersion 26
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
packagingOptions{
exclude 'META-INF/LGPL2.1'
exclude 'META-INF/LICENSE'
exclude 'META-INF/NOTICE'
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-rc02'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation project (':arcgislibrary')
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
MainActivity及其布局:
public class MainActivity extends AppCompatActivity {
private MapViewExt mapView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mapView = findViewById(R.id.map);
}
}
XML布局:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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">
<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" />
<path.to.mapviewext.components.MapViewExt
android:id="@+id/map"
mapoptions.MapType="Topo"
mapoptions.ZoomLevel="13"
mapoptions.center="40.4893538, -3.6827461"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"/>
/>
</android.support.constraint.ConstraintLayout>
我没有编译错误,一切看起来都很好,如果我编写“ Map”,在MainActivity中执行ctrl + spacebar,则可以选择MapViewExt。但是,在运行项目时,出现错误:
error: cannot access MapView
class file for com.esri.android.map.MapView not found
我的项目有什么问题?我该如何解决该错误?
编辑:
如果我将实现'com.esri.arcgis.android:arcgis-android:10.2.9'
添加到应用build.gradle
文件中,则该应用运行正常。但这是不可接受的,因为我的目标是使用我的模块制作一个aar文件,因此.aar
的用户不需要导入ESRI库。
