我希望获得我的位置的经度和经度，之后，我将其转换为位置。但我不知道我应该如何获得我所在位置的纬度和经度？
Location.java：
public class Location extends MapActivity {
MapView map;
MapController controller;
GeoPoint mygeo;
GeoPoint searchgeo;
@Override
public void onCreate(Bundle onSavedInstance){
super.onCreate(onSavedInstance);
setContentView(R.layout.location);
map=(MapView)findViewById(R.id.mapView);
LinearLayout zoomLayout=(LinearLayout)findViewById(R.id.zoom);
View zoomView=map.getZoomControls();
zoomLayout.addView(zoomView,new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT,Gravity.BOTTOM+Gravity.CENTER_HORIZONTAL));
map.displayZoomControls(true);
//
controller=map.getController();
map.setSatellite(true);
initMyLocation();
}
private void initMyLocation(){
final MyLocationOverlay overlay=new MyLocationOverlay(this,map);
overlay.enableMyLocation();
overlay.enableCompass();
overlay.runOnFirstFix(new Runnable(){
public void run(){
controller.setZoom(8);
controller.animateTo(overlay.getMyLocation());
}
});
map.getOverlays().add(overlay);
}
@Override
public boolean isRouteDisplayed(){
return false;
}
}

检查一下。它显示了如何获取当前位置，并获得其纬度和长度 GPS not update location after close and reopen app on android
请注意，您必须在清单中包含必要的权限才能使其正常工作

使用位置监听器获取您当前的位置（纬度和经度）。
这可以调用位置监听器
LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener mlocListener = new MyLocationListener();
mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
您可以在此课程中获得经度和经度
public class MyLocationListener implements LocationListener
{
@Override
public void onLocationChanged(Location loc)
{
double longitude = loc.getLongitude();
double latitude = loc.getLatitude();
}
@Override
public void onProviderDisabled(String provider)
{
Toast.makeText( getApplicationContext(),"Enable GPS",Toast.LENGTH_SHORT ).show();
Intent enablegps = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(enablegps);
}
@Override
public void onProviderEnabled(String provider)
{
Toast.makeText( getApplicationContext(), "Gps Enabled", Toast.LENGTH_SHORT).show();
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras)
{} }
希望它有所帮助。

特别是在你的情况下，在initMyLocation（）
中执行此操作double latitude = (overlay.getMyLocation().getLatitudeE6())/ 1e6;
double longitude = (overlay.getMyLocation().getLongitudeE6())/ 1e6;

请按照以下步骤操作：
步骤1：使用按钮创建如下所示的main.xml。当你按它时应该为你当前的位置祝酒。
<?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"
>
<Button
android:id="@+id/retrieve_location_button"
android:text="Retrieve Location"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
第2步：创建如下的活动：
package com.xxx.yyy.zzz;
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.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class LbsGeocodingActivity extends Activity {
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000; // in Milliseconds
protected LocationManager locationManager;
protected Button retrieveLocationButton;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
retrieveLocationButton = (Button) findViewById(R.id.retrieve_location_button);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MINIMUM_TIME_BETWEEN_UPDATES,
MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
new MyLocationListener()
);
retrieveLocationButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
showCurrentLocation();
}
});
}
protected void showCurrentLocation() {
Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location != null) {
String message = String.format(
"Current Location \n Longitude: %1$s \n Latitude: %2$s",
location.getLongitude(), location.getLatitude()
);
Toast.makeText(LbsGeocodingActivity.this, message,
Toast.LENGTH_LONG).show();
}
}
private class MyLocationListener implements LocationListener {
public void onLocationChanged(Location location) {
String message = String.format(
"New Location \n Longitude: %1$s \n Latitude: %2$s",
location.getLongitude(), location.getLatitude()
);
Toast.makeText(LbsGeocodingActivity.this, message, Toast.LENGTH_LONG).show();
}
public void onStatusChanged(String s, int i, Bundle b) {
Toast.makeText(LbsGeocodingActivity.this, "Provider status changed",
Toast.LENGTH_LONG).show();
}
public void onProviderDisabled(String s) {
Toast.makeText(LbsGeocodingActivity.this,
"Provider disabled by the user. GPS turned off",
Toast.LENGTH_LONG).show();
}
public void onProviderEnabled(String s) {
Toast.makeText(LbsGeocodingActivity.this,
"Provider enabled by the user. GPS turned on",
Toast.LENGTH_LONG).show();
}
}
}
步骤3：使用以下三个权限创建AndroidManifest.xml：
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
当你运行这个应用程序时，你会在Android设备的屏幕上找到一个按钮。当您按此按钮时，您将看到Toast消息，其中包含当前gps位置的纬度和经度。
