访问经纬度从一类到另一个 [英] Accessing latitude and longitude from one class to another

问题描述

我要访问在另一个类中纬度和一类经度的值。我有一个名为 Mylocationlistener.java A类和code如下。我想访问从 register.java 当前的经度和纬度。

我们怎样才能做到这一点？

 公共类MyLocationListener延伸活动{
       TextView的电视;
       公共静态双重纬度;
       公共静态双经度;
        公共静态INT latitude1;
         公共静态INT longitude1;
        @覆盖
          公共无效的onCreate（捆绑savedInstanceState）{
     super.onCreate（savedInstanceState）;
            的setContentView（R.layout.main）;
           //电视=（TextView中）this.findViewById（R.id.txtLocation）;
           LM的LocationManager =（的LocationManager）getSystemService（Context.LOCATION_SERVICE）;
           LocationListener的LL =新mylocationlistener（）;
          lm.requestLocationUpdates（LocationManager.NETWORK_PROVIDER，0，0，LL）;
           }
             私有类mylocationlistener实现LocationListener的{
                @覆盖
               公共无效onLocationChanged（地点）{
               今天的日期=新的日期（）;
          时间戳currentTimeStamp =新的时间戳（today.getTime（））;
                 如果（位置！= NULL）{
              Log.d（位置发生改变，location.getLatitude（）+）;
                Log.d（位置发生改变，location.getLongitude（）+）;
                 纬度=（int）的location.getLatitude（）;
                 经度=（INT）location.getLongitude（）;              字符串str =\\ n CurrentLocation：+
                 \\北纬：+ location.getLatitude（）+
              \\ n经度：+ location.getLongitude（）+
                   \\ n准确：+ location.getAccuracy（）+
    \\ n CurrentTimeStamp+ currentTimeStamp;      Toast.makeText（MyLocationListener.this，STR，Toast.LENGTH_LONG）.show（）;
      tv.append（STR）;    }
}
       @覆盖
         公共无效onProviderDisabled（字符串提供商）{
                // Toast.makeText（MyLocationListener.this，关于ProviderDisabled错误，Toast.LENGTH_LONG）.show（）;
       }
         @覆盖
          公共无效onProviderEnabled（字符串提供商）{
         // Toast.makeText（MyLocationListener.thisonProviderEnabled，Toast.LENGTH_LONG）.show（）;
}
@覆盖
公共无效onStatusChanged（字符串提供商，INT地位，捆绑演员）{
     // Toast.makeText（MyLocationListener.thisonStatusChanged，Toast.LENGTH_LONG）.show（）;
       }
              }
        }
 

从上面的类我想通过注册的.java类将其转换为整数值，以获得访问经纬度

我在Register.java这些语句

  request.addProperty（纬度，北纬**** ****）;
         request.addProperty（经度，**** ****经度）;        //这里我想从上面类访问发送值服务器
 

解决方案

按照我也有对两个选项。

选项1

您可以存储纬度和经度到MyLocationListner类的静态变量加倍，你可以注册使用类名MyLocationListener.Variable接取该变量。

选项2

您可以存储纬度和经度到共享preference和访问，在寄存器级共享preference。

I want to access the values of latitude and longitude of one class in another class. I have a class named Mylocationlistener.java and the code is given below. I want to access the current latitude and longitude from register.java.

How can we do this?

    public class MyLocationListener extends Activity {   
       TextView tv;
       public static double latitude;
       public static double longitude;
        public static int latitude1;
         public static int longitude1;
        @Override 
          public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
            setContentView(R.layout.main);         
           // tv = (TextView)this.findViewById(R.id.txtLocation);
           LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
           LocationListener ll = new mylocationlistener();
          lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, ll);    
           }  
             private class mylocationlistener implements LocationListener {
                @Override 
               public void onLocationChanged(Location location) {    
               Date today = new Date();  
          Timestamp currentTimeStamp = new Timestamp(today.getTime());
                 if (location != null) {
              Log.d("LOCATION CHANGED", location.getLatitude() + "");
                Log.d("LOCATION CHANGED", location.getLongitude() + "");
                 latitude =(int) location.getLatitude();
                 longitude = (int) location.getLongitude();

              String str = "\n CurrentLocation: "+
                 "\n Latitude: "+ location.getLatitude() + 
              "\n Longitude: " + location.getLongitude() + 
                   "\n Accuracy: " + location.getAccuracy() + 
    "\n CurrentTimeStamp "+ currentTimeStamp; 

      Toast.makeText(MyLocationListener.this,str,Toast.LENGTH_LONG).show();
      tv.append(str); 

    } 
} 
       @Override
         public void onProviderDisabled(String provider) {
                // Toast.makeText(MyLocationListener.this,"Error on   ProviderDisabled",Toast.LENGTH_LONG).show();
       }    
         @Override
          public void onProviderEnabled(String provider) {
         //       Toast.makeText(MyLocationListener.this,"onProviderEnabled",Toast.LENGTH_LONG).show();
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
     //  Toast.makeText(MyLocationListener.this,"onStatusChanged",Toast.LENGTH_LONG).show();
       }
              }
        }

from the above class I want to access latitude and longitude by converting them as integer values in order access in Register .java class

I have these statements in Register.java

         request.addProperty("latitude", ****latitude**** );
         request.addProperty("longitude",****Longitude**** );

        // here I want to send the values to server by accessing from above class

解决方案

As per me there are two options for that .

Option-1

You can store latitude and longitude into static double variable in MyLocationListner class and you can acess that variable using MyLocationListener.Variable name in register class.

Option-2

You can store that latitude and longitude into sharedPreference and access that sharedPreference in register class.
