i tried using webview but i really don't know where to add the
javascript code in it..
i tried some example using the tutorial on the net..
but could not understand it..
the link was
http://www.google.com/url?sa=D&q=http://code.google.com/apis/maps/articles/android_v3.html&usg=AFQjCNFnEdIn1isVqet3vK3d1o6BB6kT9w
i'll paste my code for you here..
WebMapActivity.java:
package com.example.hellomaps;
import android.app.Activity;
import android.content.Context;
import android.content.pm.ActivityInfo;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebMapActivity extends Activity implements
LocationListener {
/** Called when the activity is first created. */
private WebView webView;
private Location mostRecentLocation;
private static final String MAP_URL = "http://gmaps-
samples.googlecode.com/svn/trunk/articles-android-webmap/simple-
android-map.html";
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getLocation();
setupWebView();
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
private void setupWebView() {
// TODO Auto-generated method stub
final String centerURL = "javascript:centerAt(" +
mostRecentLocation.getLatitude() + "," +
mostRecentLocation.getLongitude()+ ")";
webView = (WebView) findViewById(R.id.webview);
webView.getSettings().setJavaScriptEnabled(true);
//Wait for the page to load then send the location
information
webView.setWebViewClient(new WebViewClient(){
@Override
public void onPageFinished(WebView view, String
url){
webView.loadUrl(centerURL);
}
});
webView.loadUrl(MAP_URL);
}
private void getLocation() {
// TODO Auto-generated method stub
LocationManager locationManager =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
String provider =
locationManager.getBestProvider(criteria,true);
//In order to make sure the device is getting the location,
request updates.
locationManager.requestLocationUpdates(provider, 1, 0,
this);
mostRecentLocation =
locationManager.getLastKnownLocation(provider);
}
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status,
Bundle
extras) {
// TODO Auto-generated method stub
}
and this is the javascript code..
javascript code..
<script type="text/javascript"
src="http://maps.google.com/maps/api/js?sensor=true";></script>
<script type="text/javascript">
var map;
function initialize() {
var latitude = 0;
var longitude = 0;
if (window.android){
latitude = window.android.getLatitude();
longitude = window.android.getLongitude();
}
var myLatlng = new google.maps.LatLng(latitude,longitude);
var myOptions = {
zoom: 8,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
}
function centerAt(latitude, longitude){
myLatlng = new google.maps.LatLng(latitude,longitude);
map.panTo(myLatlng);
}
</script>
