我如何输出采用Android上的GPS位置 [英] How do I output the location using gps on Android

问题描述

我想输出的位置到一个TextView。 我已经使用了locationManager.toString（），但它会只给我输出android.location.LocationManager@44ee7718。 我想输出像洛杉矶的位置，CA 90501。

在$ C $下LocationManager：

  LocationManager LM =（LocationManager）this.getSystemService（Context.LOCATION_SERVICE）;
    //转换
    标准标准=新标准（）;
    字符串BP = lm.getBestProvider（标准，FALSE）;
    位置位置= lm.getLastKnownLocation（BP）;
    双纬度= location.getLatitude（）;
    双LON = location.getLongitude（）;
    地理codeR GC =新的地缘codeR（这一点，Locale.getDefault（））;
    名单＆LT;地址＆gt;地址= NULL;
        尝试{
            地址= gc.getFromLocation（纬度，经度，1）;
        }赶上（IOException异常E）{
            // TODO自动生成的catch块
            e.printStackTrace（）;
        }
    地址地址= addresses.get（0）;
    最后弦乐广告= address.getAddressLine（0）;
    //到此为止
 

在$ C $下按钮：

  Red.setOnClickListener（新View.OnClickListener（）{
        公共无效的onClick（视图v）{
            // TODO自动生成方法存根
            意向意图=新的意图（Intent.ACTION_VIEW）;
            intent.putExtra（sms_body，广告）;
            intent.setType（vnd.android-DI​​R / MMS，SMS）;
            startActivity（意向）;
        }
    }）;
 

解决方案

试试下面的code

 尝试{
                //获取位置管理器
    locationManager =（LocationManager）getSystemService（LOCATION_SERVICE）;
                    标准标准=新标准（）;
                    bestProvider = locationManager.getBestProvider（标准，FALSE）;
                    位置位置= locationManager
                            .getLastKnownLocation（bestProvider）;
                    双纬度= location.getLatitude（）;
                    双LON = location.getLongitude（）;
                    地理codeR GC =新的地缘codeR（本）;
                    名单＆LT;地址＆gt; lstAdd = gc.getFromLocation（纬度，经度，1）;
                    地址ad = lstAdd.get（0）;
                    字符串str = ad.getAddressLine（0）;
                吐司TST = Toast.makeText（这一点，您当前的位置是+ STR，
                        Toast.LENGTH_LONG）;
                tst.show（）;
}赶上（例外五）{
                吐司TST = Toast.makeText（这一点，请检查您的GPS设置，
                        Toast.LENGTH_LONG）;
                tst.show（）;
}
 

希望这有助于。

I am trying to output the location into a textview. I have used the locationManager.toString(), but it would only give me the output android.location.LocationManager@44ee7718. I would like to output the location like Los Angeles, CA 90501.

The code for LocationManager:

LocationManager lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    //conversion
    Criteria criteria = new Criteria();
    String bp = lm.getBestProvider(criteria, false);
    Location location = lm.getLastKnownLocation(bp);
    double lat = location.getLatitude();
    double lon = location.getLongitude();
    Geocoder gc = new Geocoder(this, Locale.getDefault());
    List<Address> addresses = null;
        try{
            addresses = gc.getFromLocation(lat, lon, 1);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    Address address = addresses.get(0);
    final String ad = address.getAddressLine(0);
    //ends here

The code for the button:

Red.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent (Intent.ACTION_VIEW);
            intent.putExtra("sms_body", ad);
            intent.setType("vnd.android-dir/mms-sms");
            startActivity(intent);
        }
    });

解决方案

Try following code

try {
                // Get the location manager
    locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
                    Criteria criteria = new Criteria();
                    bestProvider = locationManager.getBestProvider(criteria, false);
                    Location location = locationManager
                            .getLastKnownLocation(bestProvider);
                    double lat = location.getLatitude();
                    double lon = location.getLongitude();
                    Geocoder gc = new Geocoder(this);
                    List<Address> lstAdd = gc.getFromLocation(lat, lon, 1);
                    Address ad = lstAdd.get(0);
                    String str = ad.getAddressLine(0);
                Toast tst = Toast.makeText(this, "Your current location is " + str,
                        Toast.LENGTH_LONG);
                tst.show();
} catch (Exception e) {
                Toast tst = Toast.makeText(this,"Please check your gps settings",
                        Toast.LENGTH_LONG);
                tst.show();
}

Hope this helps.
