Android开发 GPS获取实时时间并转为北京时间 定位信息 海拔高度 并进行显示

在转载的基础上增加一些内容，主要是时间的转换所以这里直接先把重点列出来：

(GPS时间转为本地时间)：

@SuppressLint("SimpleDateFormat")private static String getGpsLoaalTime(long gpsTime){Calendar calendar = Calendar.getInstance();calendar.setTimeInMillis(gpsTime);SimpleDateFormat df = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");String datestring = df.format(calendar.getTime());return datestring;}

上述代码需要加载Java的包支持，用eclipse会自动加载的，然后是把获取的GPS数据显示在安卓app上，代码如下：

private void updateView(Location location) { if (location != null) { editText.setText("设备位置信息\n\n时间："); editText.append(""+getGpsLoaalTime(location.getTime()); editText.append("\n经度："); editText.append(String.valueOf(location.getLongitude()));editText.append("\n纬度："); editText.append(String.valueOf(location.getLatitude()));editText.append("\n海拔："); editText.append(String.valueOf(location.getAltitude()));} else { // 清空EditText对象 editText.getEditableText().clear(); } }

上面数据的里获取时间的那一项里是转换为北京时间，单位是秒，其他的代码，别人有讲的很详细，请参考：

当然这里把整体框架也写出来：

package com.hq.gpstest;import java.text.SimpleDateFormat;import java.util.Calendar;import android.annotation.SuppressLint;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.location.Criteria;import android.location.Location;import android.location.LocationListener;import android.location.LocationManager;import android.location.LocationProvider;import android.os.Bundle;import android.provider.Settings;import android.util.Log;import android.widget.EditText;import android.widget.Toast;public class GpsActivity extends Activity {private EditText editText; private LocationManager lm; private static final String TAG = "GpsActivity"; @Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_gps);setTitle("GPS离线定位");editText = (EditText) findViewById(R.id.editText); lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); // 判断GPS是否正常启动 if (!lm.isProviderEnabled(LocationManager.GPS_PROVIDER)) { Toast.makeText(this, "请开启GPS导航...", Toast.LENGTH_SHORT).show(); // 返回开启GPS导航设置界面 Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivityForResult(intent, 0); return; } // 为获取地理位置信息时设置查询条件 String bestProvider = lm.getBestProvider(getCriteria(), true);Location location = lm.getLastKnownLocation(bestProvider); updateView(location); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, locationListener); }// 位置监听 private LocationListener locationListener = new LocationListener() { /** * 位置信息变化时触发 */ public void onLocationChanged(Location location) { updateView(location); Log.i(TAG, "时间：" + location.getTime()); Log.i(TAG, "经度：" + location.getLongitude()); Log.i(TAG, "纬度：" + location.getLatitude()); Log.i(TAG, "海拔：" + location.getAltitude()); }@Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {// TODO Auto-generated method stubswitch (status) { // GPS状态为可见时 case LocationProvider.AVAILABLE: Log.i(TAG, "当前GPS状态为可见状态"); break; // GPS状态为服务区外时 case LocationProvider.OUT_OF_SERVICE: Log.i(TAG, "当前GPS状态为服务区外状态"); break; // GPS状态为暂停服务时 case LocationProvider.TEMPORARILY_UNAVAILABLE: Log.i(TAG, "当前GPS状态为暂停服务状态"); break; } }@Overridepublic void onProviderEnabled(String provider) {// TODO Auto-generated method stubLocation location = lm.getLastKnownLocation(provider); updateView(location); }@Overridepublic void onProviderDisabled(String provider) {// TODO Auto-generated method stubupdateView(null); } };private void updateView(Location location) { if (location != null) { editText.setText("设备位置信息\n\n时间："); editText.append(""+getGpsLoaalTime(location.getTime()+(long)57647030)); editText.append("\n经度："); editText.append(String.valueOf(location.getLongitude()));editText.append("\n纬度："); editText.append(String.valueOf(location.getLatitude()));editText.append("\n海拔："); editText.append(String.valueOf(location.getAltitude()));} else { // 清空EditText对象 editText.getEditableText().clear(); } } private Criteria getCriteria() { Criteria criteria = new Criteria(); // 设置定位精确度 Criteria.ACCURACY_COARSE比较粗略，Criteria.ACCURACY_FINE则比较精细 criteria.setAccuracy(Criteria.ACCURACY_FINE); // 设置是否要求速度 criteria.setSpeedRequired(false); // 设置是否允许运营商收费 criteria.setCostAllowed(false); // 设置是否需要方位信息 criteria.setBearingRequired(false); // 设置是否需要海拔信息 criteria.setAltitudeRequired(false); // 设置对电源的需求 criteria.setPowerRequirement(Criteria.POWER_LOW); return criteria; }@SuppressLint("SimpleDateFormat")private static String getGpsLoaalTime(long gpsTime){Calendar calendar = Calendar.getInstance();calendar.setTimeInMillis(gpsTime);SimpleDateFormat df = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");String datestring = df.format(calendar.getTime());return datestring;}@Overrideprotected void onDestroy() {// TODO Auto-generated method stubsuper.onDestroy();}}

这是一个完整的程序，稍微加工一下就可以用了。
