findViewById returns null for EditText


public class MainActivity extends Activity
{
private EditText editText;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

editText = (EditText) findViewById(R.id.etext);
if(editText == null)
{
Log.v("editText", "booohooo");
}
else
{
Log.v("editText", "Success");
}

final Button button = (Button) findViewById(R.id.gobutton);

button.setOnClickListener(new View.OnClickListener() {

public void onClick(View v)
{
if(editText != null)
{
Log.v("editText", "is not NULL");
}
else
{
Log.v("editText", "is NULL :(");
}

// Perform action on click
if(editText != null)
{
editText.getText();
}
else
{
Log.v("editText", "is NULL");
}
Log.v("url", editText.getText().toString().trim());
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(editText.getText().toString().trim()));
startActivity(browserIntent);
}
});
}
}


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView android_id="@+id/websiteurlheading"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Enter web site URL"
/>
<EditText android_id="@+id/etext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/websiteurlheading"
/>
<Button android:id="@+id/gobutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Enter"
/>
</LinearLayout>


Any help is appreciated.

Answer

Make sure that setContentView(R.layout.main); is set to the correctly layout. If you have made a new one (which includes that xml code above) then use that to set the content view - setContentView(R.layout.your_xml_filename);
