在Android中根据彩色进度条绘制Mapbox多边形

// 导入Mapbox SDK的依赖
implementation 'com.mapbox.mapboxsdk:mapbox-android-sdk:10.2.0'

// 在布局文件中添加MapView控件
<com.mapbox.mapboxsdk.maps.MapView
    android:id="@+id/mapView"

    android:layout_height="match_parent" />

// 在Activity或Fragment中初始化Mapbox地图

            }
        });
