Android获取手机位置代码实现

1、项目Src下创建...service包，然后新建GPSService类

1. package com.zebra.mobilesafe.service;
2. import java.io.IOException;
3. import java.io.InputStream;
4. import android.app.Service;
5. import android.content.Intent;
6. import android.content.SharedPreferences;
7. import android.content.SharedPreferences.Editor;
8. import android.location.Criteria;
9. import android.location.Location;
10. import android.location.LocationListener;
11. import android.location.LocationManager;
12. import android.os.Bundle;
13. import android.os.IBinder;
14. import android.util.Log;
15. public class GPSService extends Service {
16. private static final String TAG = 'GPSService';
17. // 用到位置服务
18. private LocationManager lm;
19. private MyLocationListener listener;
20. @Override
21. public IBinder onBind(Intent intent) {
22. // TODO Auto-generated method stub
23. return null;
24. }
25. @Override
26. public void onCreate() {
27. // TODO Auto-generated method stub
28. super.onCreate();
29. Log.i(TAG, '====进入GPS==');
30. lm = (LocationManager) getSystemService(LOCATION_SERVICE);
31. // List<String> provider = lm.getAllProviders();
32. // for(String l: provider){
33. // System.out.println(l);
34. // }
35. listener = new MyLocationListener();
36. // 注册监听位置服务
37. // 给位置提供者设置条件
38. Criteria criteria = new Criteria();
39. criteria.setAccuracy(Criteria.ACCURACY_FINE);
40. // 设置参数细化：
41. // criteria.setAccuracy(Criteria.ACCURACY_FINE);//设置为最大精度
42. // criteria.setAltitudeRequired(false);//不要求海拔信息
43. // criteria.setBearingRequired(false);//不要求方位信息
44. // criteria.setCostAllowed(true);//是否允许付费
45. // criteria.setPowerRequirement(Criteria.POWER_LOW);//对电量的要求
46. String proveder = lm.getBestProvider(criteria, true);
47. lm.requestLocationUpdates(proveder, 0, 0, listener);
48. }
49. @Override
50. public void onDestroy() {
51. super.onDestroy();
52. // 取消监听位置服务
53. lm.removeUpdates(listener);
54. listener = null;
55. }
56. class MyLocationListener implements LocationListener {
57. /**
58. * 当位置改变的时候回调
59. */
60. @Override
61. public void onLocationChanged(Location location) {
62. String longitude = 'j:' + location.getLongitude() + '\n';
63. String latitude = 'w:' + location.getLatitude() + '\n';
64. String accuracy = 'a' + location.getAccuracy() + '\n';
65. // 发短信给安全号码
66. // 把标准的GPS坐标转换成火星坐标
67. //InputStream is;
68. //try {
69. //is = getAssets().open('axisoffset.dat');
70. //ModifyOffset offset = ModifyOffset.getInstance(is);
71. //PointDouble double1 = offset.s2c(new PointDouble(location
72. //.getLongitude(), location.getLatitude()));
73. //longitude ='j:' + offset.X+ '\n';
74. //latitude = 'w:' +offset.Y+ '\n';
75. //
76. //} catch (IOException e) {
77. //// TODO Auto-generated catch block
78. //e.printStackTrace();
79. //} catch (Exception e) {
80. //// TODO Auto-generated catch block
81. //e.printStackTrace();
82. //}
83. SharedPreferences sp = getSharedPreferences('config', MODE_PRIVATE);
84. Editor editor = sp.edit();
85. editor.putString('lastlocation', longitude + latitude + accuracy);
86. editor.commit();
87. }
88. /**
89. * 当状态发生改变的时候回调 开启--关闭 ；关闭--开启
90. */
91. @Override
92. public void onStatusChanged(String provider, int status, Bundle extras) {
93. // TODO Auto-generated method stub
94. }
95. /**
96. * 某一个位置提供者可以使用了
97. */
98. @Override
99. public void onProviderEnabled(String provider) {
100. // TODO Auto-generated method stub
101. }
102. /**
103. * 某一个位置提供者不可以使用了
104. */
105. @Override
106. public void onProviderDisabled(String provider) {
107. // TODO Auto-generated method stub
108. }
109. }
110. }

2、AndroidManiFest.xml添加类

注意这个是service类型，很容易出错，即<service  android:name='com.zebra.mobilesafe.service.GPSService'/>

3、添加权限

1. <uses-permission android:name='android.permission.ACCESS_FINE_LOCATION'/>
2. <uses-permission android:name='android.permission.ACCESS_COARSE_LOCATION'/>
3. <uses-permission android:name='android.permission.ACCESS_MOCK_LOCATION'/>

4、根据操作启动服务

1. Intent i = new Intent(context,GPSService.class);
2. context.startService(i);
