如何将Leaflet Android集成到现有应用

将Leaflet Android库集成到现有的Android应用程序中，需要遵循以下步骤：

1. 添加依赖项：在您的Android项目的build.gradle文件中，添加以下依赖项：

dependencies {     implementation 'com.github.mapbox:mapbox-android-sdk:9.6.0'     implementation 'org.apache.leaflet:leaflet-android-library:1.7.1' } 

2. 同步Gradle：点击Sync Project with Gradle Files按钮，让Gradle同步新的依赖项。

3. 在布局文件中添加地图视图：在您的布局文件中，添加一个MapView控件：

<com.mapbox.geojson.FeatureCollection     android:id="@+id/featureCollection"     android:name="features" />  <com.mapbox.maps.extension.style.layers.generated.symbolLayer     android:id="@+id/symbolLayer"     android:name="symbolLayer"     android:visibility="visible" />  <com.mapbox.maps.extension.style.sources.generated.geoJsonSource     android:id="@+id/geoJsonSource"     android:name="geoJsonSource"     android:visibility="visible" />  <com.mapbox.maps.extension.style.style     android:id="@+id/style"     android:visibility="visible" />  <com.mapbox.maps.plugin.annotation.generated.PointAnnotationManager     android:id="@+id/pointAnnotationManager"     android:visibility="visible" />  <com.mapbox.maps.extension.style.layers.generated.lineLayer     android:id="@+id/lineLayer"     android:name="lineLayer"     android:visibility="visible" />  <com.mapbox.maps.extension.style.sources.generated.vectorSource     android:id="@+id/vectorSource"     android:name="vectorSource"     android:visibility="visible" />  <com.mapbox.maps.plugin.annotation.generated.CircleAnnotationManager     android:id="@+id/circleAnnotationManager"     android:visibility="visible" />  <com.mapbox.maps.extension.style.layers.generated.fillLayer     android:id="@+id/fillLayer"     android:name="fillLayer"     android:visibility="visible" />  <com.mapbox.maps.extension.style.sources.generated.imageSource     android:id="@+id/imageSource"     android:name="imageSource"     android:visibility="visible" />  <com.mapbox.maps.extension.style.layers.generated.backgroundLayer     android:id="@+id/backgroundLayer"     android:name="backgroundLayer"     android:visibility="visible" />  <com.mapbox.maps.extension.style.style     android:id="@+id/style"     android:visibility="visible" />  <com.mapbox.maps.plugin.annotation.generated.PolygonAnnotationManager     android:id="@+id/polygonAnnotationManager"     android:visibility="visible" />  <com.mapbox.maps.extension.style.layers.generated.heatmapLayer     android:id="@+id/heatmapLayer"     android:name="heatmapLayer"     android:visibility="visible" />  <com.mapbox.maps.extension.style.sources.generated.geojsonSource     android:id="@+id/geojsonSource"     android:name="geojsonSource"     android:visibility="visible"
