本文介绍了一种在Android应用中获取用户地理位置信息的具体方法，包括使用LocationManager获取可用的位置提供者，并监听位置变化来获取经纬度坐标及地址信息。

具体方法如下：

public void getLocation() throws IOException {
    	TextView tv = (TextView)this.findViewById(R.id.mytextView);
    	StringBuffer sb = new StringBuffer();
    	
    	Location loc;
    	LocationManager locMan;
    	LocationProvider locPro;
    	
    	List<LocationProvider> proList;
    	
    	locMan = (LocationManager)this.getSystemService(LOCATION_SERVICE);
    	
    	List<String> providers = locMan.getProviders(true);
    	
    	for(String provider : providers) {
    		Log.i(TAG, provider);
    		System.out.println("--------------------------------"+provider);
    		locMan.requestLocationUpdates(provider, 
    								      1000, 0, 
    								      new LocationListener(){

											public void onLocationChanged(
													Location location) {
												// TODO Auto-generated method stub
												
											}

											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
												
											}});
    		
    		
    		Location location = locMan.getLastKnownLocation(provider);
    		//Location location = locMan.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    		//Location location = locMan.getProvider(LocationManager.GPS_PROVIDER);
    		
    		if(location!=null) {
    			sb.append("lat:").append(location.getLatitude()).append(",").append(location.getLongitude());
    			Geocoder gc = new Geocoder(this, Locale.getDefault());
    			List<Address> addresses = gc.getFromLocation(location.getLatitude(), location.getLongitude(), 10);
    			
    			if(addresses.size() > 0) {
    				Address address = addresses.get(0);
    				
    				for(int i = 0; i < address.getMaxAddressLineIndex(); i ++) {
    					sb.append(address.getAddressLine(i)).append("\n");
    					sb.append(address.getLocality()).append("\n");
    					sb.append(address.getPostalCode()).append("\n");
    					sb.append(address.getCountryName()).append("\n");
    				}
    				
    			}
    			
    			
    		} else {
    			sb.append("No Location");
    		}
    		
    		
    		tv.setText(sb);
    	}
    	
    	
    }
