我已经在这段代码上工作了一段时间,一切似乎都很好,但是我的编辑器,eclipse 一直告诉我要转换 myManager。代码如下,
package com.gps.project;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
import android.content.Context;
import android.widget.Button;
/*LOcation based API*/
import android.location.LocationManager;
public class GpsActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
/*Create ab ttuon we are to use in our GPS*/
final Button gpsButton=(Button) findViewById(R.id.gpsButton);
gpsButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
LoadCoords();
}
});
}
public void LoadCoords(){
/*Create two textfields that will contain information as latitudes and longitudes*/
TextView latText=(TextView) findViewById(R.id.latText);
TextView lngText=(TextView) findViewById(R.id.lngText);
/*Creation of a location manager from which we are to pull the location values*/
LocationManager myManager=(LocationManager) getSystemService(Context.LOCATION_SERVICE);
/*To pull the coordinates from myManager, we use the getCurrentLocation( ) method.*/
Double latPoint = myManager.getCurrentLocation("gps").getLatitude();
Double lngPoint = myManager.getCurrentLocation("gps").getLongitude();
/*Finally, take the new Double values and pass them to your TextViews:*/
latText.setText(latPoint.toString());
lngText.setText(lngPoint.toString());
}
}
如果有人帮助我纠正我的错误,我会很高兴。我打算得到经度和纬度。
