Here is my layout file. When I try to run this android app on my emulator It crashes and in the logcat I get the logcat error as :
classcastexception: android.Widget.EditText cannot be cast to android.View.ViewGroup.
I searched on google for this error and found out that this occurs when a view is not properly closed. But I checked and didnt find any mistakes.Any help and advice is appreciated. Thank you.

And here is my code to initialise these views..
public class MainActivity extends ActionBarActivity implements OnClickListener {
EditText name,age,address;
Button submit;
Spinner gender;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(4);
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.age, new PlaceholderFragment()).commit();
}
//Actual Code
initialise();
}
private void initialise() {
// TODO Auto-generated method stub
name=(EditText)findViewById(R.id.name);
age=(EditText)findViewById(R.id.age);
address=(EditText)findViewById(R.id.address);
submit=(Button)findViewById(R.id.submit);
gender=(Spinner)findViewById(R.id.gender);
submit.setOnClickListener(this);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.gender, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
gender.setAdapter(adapter);
}
}
