Body
copied!<p>Firstly I've only been coding in Android/Java for a couple weeks so apologies if this is a simple question or if I don't understand your answer.</p> <p>I'm trying to take the latitude and longitude data from the phone and then use this in the following sunrise/sunset webservice: <a href="http://www.earthtools.org/webservices.htm" rel="nofollow">http://www.earthtools.org/webservices.htm</a></p> <p>I have managed to set up a button display the latitude and longitude in a textview and I have set another button up to display the result of the webservice using a static url. Now I just need to combine the two.</p> <p>How do I go about taking the latitude and longitude data and putting into the url of the webservive? (<a href="http://www.earthtools.org/sun/" rel="nofollow">http://www.earthtools.org/sun/</a><strong>LATITUDE/LONGITUDE</strong>/28/03/99/0)</p> <p>Here is how my code currently looks:</p> <pre><code> package richgrundy.learnphotography; import android.app.Activity; import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.TextView; import java.io.IOException; import java.io.InputStream; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.protocol.BasicHttpContext; import org.apache.http.protocol.HttpContext; import android.os.AsyncTask; import android.widget.EditText; public class SunriseSunset extends Activity implements OnClickListener { public Button getLocation; public TextView LongCoord; public TextView LatCoord; public double longitude; public double latitude; public LocationManager lm; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.sunrisesunset); findViewById(R.id.my_button).setOnClickListener(this); lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, new MyLocationListener()); getLocation = (Button) findViewById(R.id.GetLocation); LongCoord = (TextView) findViewById(R.id.LongCoord); LatCoord = (TextView) findViewById(R.id.LatCoord); getLocation.setOnClickListener(new OnClickListener() { @Override public void onClick(View arg0) { showCurrentLocation(); } }); } protected void showCurrentLocation() { // TODO Auto-generated method stub Location location = lm .getLastKnownLocation(LocationManager.GPS_PROVIDER); latitude = location.getLatitude(); longitude = location.getLongitude(); LongCoord.setText(Double.toString(longitude)); LatCoord.setText(Double.toString(latitude)); } @Override public void onClick(View arg0) { Button b = (Button) findViewById(R.id.my_button); b.setClickable(false); new LongRunningGetIO().execute(); } private class LongRunningGetIO extends AsyncTask<Void, Void, String> { protected String getASCIIContentFromEntity(HttpEntity entity) throws IllegalStateException, IOException { InputStream in = entity.getContent(); StringBuffer out = new StringBuffer(); int n = 1; while (n > 0) { byte[] b = new byte[4096]; n = in.read(b); if (n > 0) out.append(new String(b, 0, n)); } return out.toString(); } @Override protected String doInBackground(Void... params) { HttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpGet httpGet = new HttpGet( "http://www.earthtools.org/sun/52.77431872/-1.20639/28/03/99/0"); String text = null; try { HttpResponse response = httpClient.execute(httpGet, localContext); HttpEntity entity = response.getEntity(); text = getASCIIContentFromEntity(entity); } catch (Exception e) { return e.getLocalizedMessage(); } return text; } protected void onPostExecute(String results) { if (results != null) { EditText et = (EditText) findViewById(R.id.my_edit); et.setText(results); } Button b = (Button) findViewById(R.id.my_button); b.setClickable(true); } } class MyLocationListener implements LocationListener { @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 } } } </code></pre> <p>I tried using the following code but couldn't get that to work:</p> <pre><code> HttpClient httpClient = new DefaultHttpClient(httpParameters); HttpContext localContext = new BasicHttpContext(); String url = "http://www.earthtools.org/sun/" + String.valueOf(location.getLatitude()) + "," + String.valueOf(location.getLongitude()) + "/28/03/99/0"; HttpGet httpGet = new HttpGet(url); </code></pre> <p>Any help would be massively appreciated as I've been stuck on this for a couple days now.</p> <p>Thanks =)</p>
