我是KIVY,pyjnius和PythonAndroid的新手。我需要为android制作一个简单的应用程序,显示GPS坐标。但是,就像我说的,我是新来的基维和小圆孔虫。有人能给我举个例子,在简单的kivy标签小部件中显示我的坐标吗? 谢谢!
我试过这样做,但是。。。
package org.renpy.android;
//import java.util.ArrayList;
//import java.util.List;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.content.Context;
import android.os.Bundle;
import android.os.Looper;
import java.lang.Thread;
import android.app.Activity;
public class KivyGps {
LocationManager lm;
Thread gpsThread;
public long minDistance = 1;
public int minTime = 1000;
static class KivyLocationListener implements LocationListener {
public Location lastLocation = new Location("Other");
//private List<LocationListener> listeners = new ArrayList<LocationListener>();
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
lastLocation = location;
//updateListeners(location);
}
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
// TODO Auto-generated method stub
return lastLocation;
}
}
static public KivyLocationListener locationListener = new KivyLocationListener();
public Thread init(final Activity currActivity) {
gpsThread = new Thread( new Runnable() {
public void run() {
try {
Looper.prepare();
lm = (LocationManager) currActivity.getSystemService( Context.LOCATION_SERVICE );
lm.requestLocationUpdates( LocationManager.GPS_PROVIDER, minTime, minDistance, locationListener );
Looper.loop();
}
catch ( Exception e ) {
e.printStackTrace();
}
}
} );
return gpsThread;
}
//gpsThread.start();
}
在python中
from jnius import autoclass
LocationListener = autoclass('android.location.LocationListener')
LocationManager = autoclass('android.location.LocationManager')
LocationProvider = autoclass('android.location.LocationProvider')
Location = autoclass('android.location.Location')
Looper = autoclass('android.os.Looper')
Context = autoclass('android.content.Context')
KivyGps = autoclass('org.renpy.android.KivyGps')
currentActivity = cast('android.app.Activity', PythonActivity.mActivity)
lm = currentActivity.getSystemService( Context.LOCATION_SERVICE)
if lm.isProviderEnabled( LocationManager.GPS_PROVIDER ):
print 'CON GPS'
else:
print 'SIN GPS'
lps = lm.getAllProviders()
for lp in lps.toArray():
print lp
#Arreglar problema de derechos ACCESS_FINE_LOCATION en Kivy Launcher
lp = lm.getProvider('gps')
ll = KivyGps.locationListener
kgps = KivyGps()
gpsThread = kgps.init( currentActivity )
gpsThread.start()
loc = ll.getCurrentLocation()
if loc:
print loc.getLatitude()
print loc.getLongitude()
Plyer是一个Python库,用于访问硬件/平台的特性。
刚找到,所以我不太了解。
文件:
https://plyer.readthedocs.org/en/latest/
资料来源:
https://github.com/kivy/plyer
在这个Kivy Github问题上找到了它:
https://github.com/kivy/kivy/issues/994
我刚才在Kivy/pyjnius中做了一个访问GPS的演示:
https://github.com/tito/android-demo
看看源代码,一切都在里面。
现在可以使用Plyer:http://github.com/kivy/plyer。
它支持GPS。
