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：

super.onCreate(savedInstanceState);

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);

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() {

}

@Override

}
};

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;
}

@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
}

这是一个完整的程序，稍微加工一下就可以用了。
