在Android模拟器中模拟GPS

package org.exapmle.locationtest;

import android.app.Activity;

import android.content.Context;

import android.location.Criteria;

import android.location.Location;

import android.location.LocationListener;

import android.location.LocationManager;

import android.os.Bundle;

import android.widget.TextView;

public class LocationTestActivity extends Activity {

/** Called when the activity is first created. */

TextView myLocationText;

TextView myLongitude;

TextView myLatitude;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

LocationManager locationManager;

String serviceName=Context.LOCATION_SERVICE;

// dumpProviders();

locationManager=(LocationManager)this.getSystemService(serviceName);

//查询条件

Criteria criteria=new Criteria();

criteria.setAccuracy(Criteria.ACCURACY_FINE);

criteria.setAltitudeRequired(false);

criteria.setBearingRequired(false);

criteria.setCostAllowed(true);

criteria.setPowerRequirement(Criteria.POWER_LOW);

//选择最佳的提供者

String provider=locationManager.getBestProvider(criteria,true);

//查询上一个已知的位置

Location location=locationManager.getLastKnownLocation(provider);

updateWithNewLocation(location);

//设置监听器，自动更新的最小时间为间隔1秒，最小位移变化超过5米

locationManager.requestLocationUpdates(provider, 1000, 5, locationListener);

}

private final LocationListener locationListener = new LocationListener(){

public void onLocationChanged(Location location) {

updateWithNewLocation(location);}

public void onProviderDisabled(String provider) {}

public void onProviderEnabled(String provider) {}

public void onStatusChanged(String provider, int status, Bundle extras) {}

};

private void updateWithNewLocation(Location location){

myLocationText = (TextView)this.findViewById(R.id.myLocationText);

myLongitude = (TextView)this.findViewById(R.id.myLongitude);

myLatitude = (TextView)this.findViewById(R.id.myLatitude);

if(location!=null){

myLongitude.setText(String.valueOf(location.getLongitude()));

myLatitude.setText(String.valueOf(location.getLatitude()));

}else{

myLongitude.setText("No GPS");

}

myLocationText.setText("您所在位置为:");

}

}

GPS测试

如果是在模拟器中调试的话，有二种方法可以进行GPS测试。

第一：通过DDMS。打开"Window->Show View->Other” 中打开"Emulator Control” View即可手动设置地理位置数据，如下图所示：
