android - 无法从 Android 中的反向地理编码打印地址

Question

我引用了Stack overflow的很多问题，实现了上面的过程。但我无法获得地址。请让我知道如果我错过了什么..？ myLoc = (TextView) findViewById(R.id.id1);

Geocoder geocoder = new Geocoder(getBaseContext(),Locale.getDefault());
try {
    address = geocoder.getFromLocation(latitude, longitude, 1);
                if (address.size() > 0) {
        for (int i = 0; i < address.get(0)
                .getMaxAddressLineIndex(); i++) {
            display = "";
            display += address.get(0).getAddressLine(i)
                    + "\n";
        }
        }

} catch (Exception e2) {
    // TODO: handle exception
}
myLoc.setText("Current Location:"+display);
System.out.println(display);

您可以使用反向地理编码和 Google api 从纬度和经度获取地址。

反向地理编码:

 double currentLatitude;
    double currentLongitude;

void getAddress(){
        try{
            Geocoder gcd = new Geocoder(this, Locale.getDefault());
            List<Address> addresses = 
                gcd.getFromLocation(currentLatitude, currentLongitude,100);
            if (addresses.size() > 0) {
                StringBuilder result = new StringBuilder();
                for(int i = 0; i < addresses.size(); i++){
                    Address address =  addresses.get(i);
                    int maxIndex = address.getMaxAddressLineIndex();
                    for (int x = 0; x <= maxIndex; x++ ){
                        result.append(address.getAddressLine(x));
                        result.append(",");
                    }               
                    result.append(address.getLocality());
                    result.append(",");
                    result.append(address.getPostalCode());
                    result.append("\n\n");
                }
                addressText.setText(result.toString());
            }
        }
        catch(IOException ex){
            addressText.setText(ex.getMessage().toString());
        }
    }

Google API:请参阅此 api，它从纬度和经度返回地址
