尝试在 GoogleMap ( googleMap
) 上绘制标记。属性存储在 CSV 文件中,其结构为name
、code
(主要用作片段)latitude
和longitude
. 这没有任何错误,但没有正确编译
String name;
String code;
String latitude;
String longitude;
String fileName;
fileName = "sleepertrain5/assests/stations.csv";
InputStream is = null;
try {
is = getAssets().open(fileName);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
try {
String line;
while ((line = reader.readLine()) != null) {
String[] RowData = line.split(",");
name = RowData[0];
code = RowData[1];
latitude= RowData[2];
longitude=RowData[3];
String latAmount=latitude;
double amount1=Float.parseFloat(latAmount);
String longAmount=latitude;
double amount2=Float.parseFloat(longAmount);
googleMap.addMarker(new MarkerOptions()
.position(new LatLng(amount1, amount2))
.title(name)
.snippet("Station code: "+ code));
}
}
catch (IOException ex) {
// handle exception
}
finally {
try {
is.close();
}
catch (IOException e) {
// handle exception
}
关于我将如何做到这一点的任何帮助?
