So ive just begun to start on my android development learning journey
and got this book Profession Android Application Development, but I
cant get this certain sample code to run and im so new to the sdk I
cant spot the problem. Well obviously eclipse tells me why it wont
compile ive gotten it down from a host of errors just importing
thhings into the document but one red line is still under new
OnKeyListener. Any suggestions appreciated I feel i have too many
imports as well so let me know just started learning hate when these
book examples dont work.
package com.paad.todolist;
import android.app.Activity;
import android.os.Bundle;
import android.view.*;
import android.widget.*;
import android.util.*;
import java.util.*;
public class ToDoList extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
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 Array List of Todo Items
final ArrayList<String> todoItems = new ArrayList<String>();
//Create array adapter to bind arraylist to list items
final ArrayAdapter<String> aa;
aa = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
todoItems);
//bind to list view
myListView.setAdapter(aa);
//Setup next user next entry
myEditText.setOnKeyListener(new OnKeyListener(){
public boolean onKey(View v, int keyCode, keyEvent event){
if (event.getAction()== keyEvent.ACTION_DOWN)
if (keyCode == keyCode.KEYCODE_DPAD_CENTER)
{
todoItems.add(0,
myEditText.getText().toString());
aa.notifyDataSetChanged();
myEditText.setText("");
return true;
}
return false;
}
});
}
}
