  Package dk.troll.android; Import android App Import android.content.Intent; Import android.net.Uri; Importroid.os.Bundle; Import android.widget.Button; Import android.view.View; Import android.view.View.OnClickListener; Override public class main activity activity (button button; @Create) overwrite public zeros (bundle saved instenstate) {super.naught (savedinstenstate); setContentView (R.layout.main); addListenerOnButton ();} Public Zero addListenerOnButton () {Button = (button) findViewById (R.id.button1); button.setOnClickListener (New OnClickListener) {@Override Public Zero onClick (see arg0) {intro browserIntent = new intent (Intent.ACTION_VIEW, Uri.parse ( "Http://www.troll.dk"); startActivity (browserIntent);}})}}

and this is my XML file 

 < Code> & lt; xml no Version = "1.0" encoding = "UTF-8"? & Gt; LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" Android: Orientation = "Vertical" Android: Layout_width = "fill_parent" Android: layout_height = "fill_parent" & gt; TextView Android: layout_width = "fill_parent" Android: layout_height = "wrap_content" Android: text = "home epsom and so many other stuff" /> & Lt; Button Android: id = "@ + id / Button1" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" android: text = "button - go troll" /> & Lt; / LinearLayout & gt;

button = (button) findViewById (R.id.button1) on this line; Error can not be found I can not

r

Content of the class

generated, how can I fix the error?

Fist restart eclipse

Then do this:

1. Import R Class for your activity, import dk.troll.android.R;

2. Make sure that there is no error in all the files in the scripts, then try to clean the project from the clean project.

3. Build your project
