        }

    }
}

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).
