以下是一段Java代码,可以在Android Studio中下载指定网站上的zip文件,解析其中的shp文件,并通过高德接口绘制到地图上:
```
import java.io.*;
import java.net.URL;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class DownloadAndDrawShp {
public static void main(String[] args) throws Exception {
String url = "http://example.com/shapefile.zip";
String shpFileName = "shapefile.shp";
// Download the zip file
URL zipUrl = new URL(url);
InputStream zipStream = zipUrl.openStream();
ZipInputStream zip = new ZipInputStream(zipStream);
// Find the shp file in the zip
ZipEntry entry;
while ((entry = zip.getNextEntry()) != null) {
if (entry.getName().equals(shpFileName)) {
// Read the shp file
BufferedReader reader = new BufferedReader(new InputStreamReader(zip));
String line;
while ((line = reader.readLine()) != null) {
// Parse the shp file and draw on the map using AMap API
// ...
}
reader.close();
break;
}
}
zip.close();
}
}
```
请注意,这段代码只是一个示例,需要根据实际情况进行修改和完善。
