Ok so I kind of implemented this, but it forces close when I click the
button.. What am I doing wrong?
================================
package net.gullycorp.example.webtest;
import java.io.IOException;
import org.apache.http.client.ClientProtocolException;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
public class WebTest extends Activity implements OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button clickme = (Button) findViewById(R.id.clickme);
clickme.setOnClickListener(this);
}
public void onClick(View view) {
int id = view.getId();
switch(id) {
case R.id.clickme:
EditText urlText = (EditText) findViewById(R.id.textbox);
String url = urlText.getText().toString();
grabSource(url);
break;
}
}
private void grabSource(String url) {
new GrabURLTask().execute();
}
private class GrabURLTask extends AsyncTask<String, Void, Void> {
protected void onPreExecute() {
Utilities.showToast(WebTest.this, "Loading..", true);
}
protected Void doInBackground(String... params) {
final Webat client = new Webat();
boolean success = false;
try {
client.getURL(params[0]);
success = true;
} catch (ClientProtocolException e) {
Utilities.showToast(WebTest.this,
e.getMessage(), true);
cancel(true);
} catch (IOException e) {
Utilities.showToast(WebTest.this,
e.getMessage(), true);
cancel(true);
}
return null;
}
protected void onPostExecute(Void unused) {
Utilities.showToast(WebTest.this, "Source loaded.",
true);
}
}
}
===========================================
Apologies for the large paste, I can pastie it if it's preferable?
Thanks,
Lee
