hello all,
this is my first attempt at the UI. i tried to create a list view
using the following code:
package com.paad.todolist2;
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnKeyListener;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import android.widget.ListView;
public class ToDoList2 extends Activity {
/** Called when the activity is first created. */
// @Override
// public void onCreate(Bundle savedInstanceState) {
// super.onCreate(savedInstanceState);
// setContentView(R.layout.main);
// }
public void onCreate(Bundle savedInstanceState) {
// Inflate your view
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Get references to UI widgets
ListView myListView = (ListView)findViewById(R.id.myListView);
final EditText myEditText =
(EditText)findViewById(R.id.myEditText);
// Create the array list of to do items
final ArrayList<String> todoItems = new ArrayList<String>();
// Create the array adapter to bind the array to the listview
final ArrayAdapter<String> aa;
aa = new
ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,todoItems);
// Bind the array adapter to the listview.
myListView.setAdapter(aa);
myEditText.setOnKeyListener(new OnKeyListener() {
public boolean onKey1(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN)
if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER)
{
todoItems.add(0, myEditText.getText().toString());
aa.notifyDataSetChanged();
myEditText.setText(" ");
return true;
}
return false;
}
@Override
public boolean onKey(View arg0, int arg1, KeyEvent
arg2) {
// TODO Auto-generated method stub
return false;
}
});
}
}
but, the line:
ListView myListView = (ListView)findViewById(R.id.myListView);
is giving an error :"R.id cannot be resolved".
please help me regarding this.
regards
