配置Google API SDK

  配置Google API SDK，新建一个适合Google SDK的虚拟机，选择

Google APIs(Google Inc.)-API Level 10

  使用Google API启动的虚拟机存在一个Maps的机制。

  新建项目的时候选择Google APIs(Google Inc.)(API 10)

 

 

 

 

新建一个地图项目。

 

 

在main.xml中：

 

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

  xmlns:android="http://schemas.android.com/apk/res/android"

  android:orientation="vertical"

  android:layout_width="fill_parent"

  android:layout_height="fill_parent"

  android:background="#3399ff">

  <TextView

     android:id="@+id/msg"

     android:layout_marginTop="8dp"

     android:layout_marginLeft="80dp"

     android:layout_width="fill_parent"

     android:layout_height="wrap_content"

     android:textColor="#ffffff"

     android:text="等待接收位置信息..." />

</LinearLayout>

 

 

 

 

在MyGPSDemo.java中：

 

package com.li.gprs;

 

import android.app.Activity;

import android.content.Context;

import android.location.Location;

import android.location.LocationListener;

import android.location.LocationManager;

import android.os.Bundle;

import android.widget.TextView;

 

public class MyGPSDemo extends Activity {

  private TextView msg = null;

  private LocationManager locationManager = null;

 

  @Override

  public void onCreate(Bundle savedInstanceState) {

     super.onCreate(savedInstanceState);

     super.setContentView(R.layout.main);

     this.msg = (TextView) super.findViewById(R.id.msg);

     this.locationManager = (LocationManager) super

         .getSystemService(Context.LOCATION_SERVICE);

     this.locationManager.requestLocationUpdates(

         LocationManager.GPS_PROVIDER, 1000, 1,

         new LocationListenerImpl());

  }

 

  private class LocationListenerImpl implements LocationListener {

 

     public void onLocationChanged(Location location) { // 位置改变

       MyGPSDemo.this.msg.setText("用户位置发生改变，新的数据：\n" + "经度："

            + location.getLongitude() + "\n" + "纬度："

            + location.getLatitude() + "\n" + "数据准确度："

            + location.getAccuracy() + "\n" + "时间："

            + location.getTime() + "\n" + "速度：" + location.getSpeed()

            + "\n" + "方位：" + location.getBearing());

     }

 

     public void onProviderDisabled(String provider) {

 

     }

 

     public void onProviderEnabled(String provider) {

 

     }

 

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

 

     }

 

  }

}

 

 

 

在AndroidManifest.xml中配置权限：

 

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.li.gprs"

    android:versionCode="1"

    android:versionName="1.0" >
