Question

I am creating a listView in Android using the following code :

 ListView listView = (ListView) List.this.findViewById(R.id.mylist);
         listView.setTextFilterEnabled(true);

         String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
            "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
            "Linux", "OS/2" ,"asdsad","asdsdsa","asdasdsa"};

         ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item,values);

            // Assign adapter to ListView

            listView.setAdapter(adapter);
            listView.setVisibility(0);

Now I want to Toast a selected Item from my ListView so I use the following code :

listView.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position,
                        long id) {

                    String item = ((TextView)view).getText().toString();

                    Toast.makeText(getBaseContext(), item, Toast.LENGTH_LONG).show();

                }
            });

But Unfortunately I am getting error for the following piece of code

listView.setOnItemClickListener(new OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view, int position,
                            long id)

The error is

The type new AdapterView.OnItemClickListener(){} must implement the inherited abstract method
AdapterView.OnItemClickListener.onItemClick(AdapterView, View, int, long)

So What Should I do to correct this error and also print my listview element?
Edited

Entire Code

package com.notification;

import android.os.Bundle;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.RelativeLayout;
import android.widget.Toast;
import android.view.*;

public class List1 extends Activity 
{

Context context=this;

@Override
        public void onCreate(Bundle savedInstanceState)
        {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.listview);
        //ListView
        try{

         ListView listView = (ListView) List1.this.findViewById(R.id.mylist);
         listView.setTextFilterEnabled(true);

         String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
            "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
            "Linux", "OS/2" ,"asdsad","asdsdsa","asdasdsa"};

         ArrayAdapter<String> adapter = new ArrayAdapter<String>(context,R.layout.list_item,values);

            // Assign adapter to ListView

            listView.setAdapter(adapter);
            listView.setVisibility(0);

            //required
            listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                public void onItemClick(AdapterView<?> parent, View view, int position,long id)
                //public void onItemClick(ListView<?> listview, View view, int position,long id)
                {

                 Toast.makeText(List1.this, "hi",Toast.LENGTH_LONG).show();
                }
            });


            //required
            }
       catch(Exception e)
       {
        Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();}
       }
}

Nothing is getting toasted. why?

Edit 2
list_item.xml

<?xml version="1.0" encoding="utf-8"?>



<Button xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:id="@+id/tv1"
    android:padding="10dp"
    android:background="@drawable/textview1"
    style="@style/textview_text"
    android:textSize="16dp">


</Button>

listview.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >


  <ListView
        android:id="@+id/mylist"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >
    </ListView>

</RelativeLayout>

Answer 1

You have set your java compiler version to 1.5 so its giving error.

Two things you can do.

1) remove @Override written before onItemClick

2) right-click project - properties - java compiler - check-Enable project setting - change to 1.6

Also there is other changes required.

Use YouActivityName.this instead getBaseContext() while showing Toast

Item can be null so change…String item = values[position]
