Two simple [probably] coding questions

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:orientation="vertical" >
 
 <EditText
     android:id="@+id/etNum"
     android:layout_width="wrap_content"
     android:layout_height="102dp"
     android:hint="@string/Please enter a department number." 
     android:inputType="number"
     />
 
     <EditText
     android:id="@+id/etName"
     android:layout_width="wrap_content"
     android:layout_height="102dp"
     android:hint="@string/Or enter a department name." 
     android:inputType="string"
     />
 
     <requestFocus />
 
 
 </LinearLayout>
 

** Q#1. Right at the last line, i get Multiple annotations found at this line:
- error: Error parsing XML: mismatched tag
- This text field does not specify an inputType
or a hint. Not sure what to do? **

package walmart.namespace;
 
 
 import android.R;
 import android.R.string;
 import android.app.Activity;
 import android.os.Bundle;
 import android.view.View;
 import android.widget.Button;
 import android.widget.TextView;
 
 public class WalmartActivity extends Activity {
 /** Called when the activity is first created. */
 
 int department;
 String name;
 Button search;
 TextView display;
 @Override
 public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
 

q#2: For the R.Layout.main, i have 'main cannot be resolved or is not a field'. I know i shouldn't use the import android.R in the imports, but it at least gets rid of the problem being the R. Any ideas on how to fix this?
