        }

    }
}

This is my Event adapter class

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;

public class EventAdapter extends ArrayAdapter<String> {

    private final Activity context;
    private final String[] itemname;
    private final String[] itemname2;
    private final String[] itemname3;

    public EventAdapter(Activity context, String[] itemname,String[] itemname3,String[] itemname2) {
        super(context, R.layout.myevent, itemname);
        // TODO Auto-generated constructor stub

        this.context=context;
        this.itemname=itemname;
        this.itemname3=itemname3;
        this.itemname2=itemname2;

    }

    public View getView(int position,View view,ViewGroup parent) {
        LayoutInflater inflater=context.getLayoutInflater();
        View rowView=inflater.inflate(R.layout.myevent, null, true);

        TextView txtTitle = (TextView) rowView.findViewById(R.id.item);
        TextView extratxt1 = (TextView) rowView.findViewById(R.id.textView1);
        TextView extratxt2 = (TextView) rowView.findViewById(R.id.textView2);

        txtTitle.setText(itemname[position]);
        extratxt1.setText(itemname2[position]);
        extratxt2.setText(itemname3[position]);
        return rowView;

    };
}

This is my Activitymain xml code for list view

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="${relativePackage}.${activityClass}" >

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</RelativeLayout>

The list view successfully get gets updated but when i click an option in list view that shows up an toast,the position i clicked it shows an error

Answer 1

int Slecteditem = position;
Toast.makeText(getApplicationContext(), Slecteditem, Toast.LENGTH_SHORT).show();

You are using the item position for the message argument. Toast doesn't know about your adapter and thinks you are giving it a string resource ID, but fails to find a string with that ID (in this case 2). You either need to use an actual string resource id, or an actual String.

Since your adapter extends ArrayAdapter, you could use adapter.getItem(position) instead (which I suspect is what you intended to do).
