本文介绍了纬度不显示的是Android的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我只是想调试，并确保我得到正确的经度和纬度信息。当一个TextView显示经度和纬度，经度显示正确，但纬度始终是0.0不管我用NETWORK_PROVIDER或GPS_PROVIDER。这是一个常见的问题？我对待纬度酷似经度，那么为什么它不工作这不是明显对我。感谢您提前帮助。
下面是我的code的位置的东西，以防万一（介意变量名）：
的TextView textLat;
TextView的textLong;
TextView的textSpeed;保护无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_display_navigation）; textLat =（的TextView）findViewById（R.id.textLat）;

textSpeed =（的TextView）findViewById（R.id.speed_lol）; 的LocationManager bubbleButt =（的LocationManager）this.getSystemService（Context.LOCATION_SERVICE）;
LocationListener的bbListener =新mylocationlistener（）; 位置lastLocation = bubbleButt.getLastKnownLocation（LocationManager.NETWORK_PROVIDER）; 如果（lastLocation！= NULL）
{
textLat.setText（Double.toString（lastLocation.getLatitude（）））;
textLong.setText（Double.toString（lastLocation.getLongitude（）））;
}
bubbleButt.requestLocationUpdates（LocationManager.NETWORK_PROVIDER，0，0，bbListener）;
} 类mylocationlistener实现LocationListener的{ @覆盖

.isProviderEnabled（LocationManager.NETWORK_PROVIDER）; 如果（isGPSEnabled＆安培;！＆安培;！isNetworkEnabled）{
//没有启用网络供应商
}其他{

//首先从网络提供商处获取位置
如果（isNetworkEnabled）{

和这code将主要活动在创建方法

经度= gps.getLongitude（）; // Toast.makeText（

//您现在的位置是 - \\ nLat：+纬度+\\ nLong：

}其他{
gps.showSettingsAlert（）;
} Log.e（经纬度，+纬度++经度）;
I'm just trying to debug and make sure I'm getting correct longitude and latitude information. When displaying latitude and longitude with a TextView, the longitude displays correctly, but the latitude is always 0.0 no matter if I use NETWORK_PROVIDER or GPS_PROVIDER. Is this a common problem? I am treating latitude exactly like longitude, so it's not obvious to me why it is not working. Thanks for help in advance.
Here is my code for the location stuff, just in case (mind the variable names):
TextView textLat;
TextView textLong;
TextView textSpeed;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_display_navigation);
textLat = (TextView) findViewById(R.id.textLat);
textLong = (TextView) findViewById(R.id.textLong);
textSpeed = (TextView) findViewById(R.id.speed_lol);
LocationManager bubbleButt = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
LocationListener bbListener = new mylocationlistener();
Location lastLocation = bubbleButt.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (lastLocation != null)
{
textLat.setText(Double.toString(lastLocation.getLatitude()));
textLong.setText(Double.toString(lastLocation.getLongitude()));
}
bubbleButt.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, bbListener);
}
class mylocationlistener implements LocationListener{
@Override
public void onLocationChanged(Location location) {
if(location != null)
{
double pLong = location.getLongitude();
double pLat = location.getLatitude();
double stupid = location.getSpeed();
textLat.setText(Double.toString(pLat));
textLong.setText(Double.toString(pLong));
textLat.setText(Double.toString(stupid));
}
解决方案
first to you use this code for the get devices current loacation.
package com.deals;
import android.app.AlertDialog;
import android.app.Service;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.provider.Settings;
import android.util.Log;
public class GPSTracker extends Service implements LocationListener {
private final Context mContext;
// flag for GPS status
boolean isGPSEnabled = false;
// flag for network status
boolean isNetworkEnabled = false;
// flag for GPS status
boolean canGetLocation = false;
Location location; // location
double latitude; // latitude
double longitude; // longitude
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
// Declaring a Location Manager
protected LocationManager locationManager;
public GPSTracker(Context context) {
this.mContext = context;
getLocation();
}
public Location getLocation() {
try {
locationManager = (LocationManager) mContext
.getSystemService(LOCATION_SERVICE);
// getting GPS status
isGPSEnabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
isNetworkEnabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (!isGPSEnabled && !isNetworkEnabled) {
// no network provider is enabled
} else {
this.canGetLocation = true;
// First get location from Network Provider
if (isNetworkEnabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("Network", "Network");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
// if GPS Enabled get lat/long using GPS Services
if (isGPSEnabled) {
if (location == null) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
Log.d("GPS Enabled", "GPS Enabled");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return location;
}
/**
* Stop using GPS listener
* Calling this function will stop using GPS in your app
* */
public void stopUsingGPS(){
if(locationManager != null){
locationManager.removeUpdates(GPSTracker.this);
}
}
/**
* Function to get latitude
* */
public double getLatitude(){
if(location != null){
latitude = location.getLatitude();
}
// return latitude
return latitude;
}
/**
* Function to get longitude
* */
public double getLongitude(){
if(location != null){
longitude = location.getLongitude();
}
// return longitude
return longitude;
}
/**
* Function to check GPS/wifi enabled
* @return boolean
* */
public boolean canGetLocation() {
return this.canGetLocation;
}
/**
* Function to show settings alert dialog
* On pressing Settings button will lauch Settings Options
* */
public void showSettingsAlert(){
AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext);
// Setting Dialog Title
alertDialog.setTitle("GPS is settings");
// Setting Dialog Message
alertDialog.setMessage("GPS is not enabled. Do you want to go to settings menu?");
// On pressing Settings button
alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int which) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
mContext.startActivity(intent);
}
});
// on pressing cancel button
alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
// Showing Alert Message
alertDialog.show();
}
@Override
public void onLocationChanged(Location location) {
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public IBinder onBind(Intent arg0) {
return null;
}
}
and this to code put main activity to on create method
gps = new GPSTracker(getActivity());
if (gps.canGetLocation()) {
latitude = gps.getLatitude();
longitude = gps.getLongitude();
// Toast.makeText(
// getApplicationContext(),
// "Your Location is - \nLat: " + latitude + "\nLong: "
// + longitude, Toast.LENGTH_LONG).show();
} else {
gps.showSettingsAlert();
}
Log.e("latlong", "" + latitude + "" + longitude);
