我是机器人编程初学者。我的研究生项目是跟踪一个移动设备，我需要在code保存位置（不使用GPS）为文本文件。有人建议我C $ CS的$这样做的。这将是对我来说是很大的帮助。

试试这个。

  locationManagerNetwork =（LocationManager）getSystemService（Context.LOCATION_SERVICE）;
    地点地点2 = locationManagerNetwork
                    .getLastKnownLocation（LocationManager.NETWORK_PROVIDER）;

     如果（LOCATION2！= NULL）{
                字符串消息=字符串
                        .format（YOUT位置：\ñ经度：％1 $ S \北纬：％2 $ S，
                                location2.getLongitude（），location2.getLatitude（））;
                Toast.makeText（getApplicationContext（），消息，Toast.LENGTH_LONG）
                        。显示（）;


    //这里使用的文件作家，如果你想要写在一个文本文件中的coordinastes
            }
 

写入SD卡

 文件SD卡= Environment.getExternalStorageDirectory（）;
        文件F =新的文件（SD卡，/ yourfile）;

如果（！f.exsist（））{
f.createNewFile（）;
//使用outwriter这里，OutputStream的搜索如何编写成的Java code进行TET文件
}
 

I am a beginner in android programming. My Graduate project is about tracking a mobile device and i need the code to save the location( Without using GPS) as a text file. Someone suggest me the codes for doing that. It will be a great help for me.

Try this.

locationManagerNetwork = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    Location location2 = locationManagerNetwork
                    .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

     if (location2 != null) {       
                String message = String
                        .format("Yout location : \n Longitude: %1$s \n Latitude: %2$s",
                                location2.getLongitude(), location2.getLatitude());
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG)
                        .show();


    //use here file writer if you want to write the coordinastes in a text file
            }

for writing sd card

File sdcard = Environment.getExternalStorageDirectory();
        File f = new File(sdcard, "/yourfile");

if(!f.exsist()){
f.createNewFile();
//Use outwriter here, outputstream search how to write into a tet file in java code 
}
