Question

I currently have a ListActivity and I am looking to start a new activity based on the selection in the list. Based upon Intents and Extras, how can I make this possible? Here is my code so far:

package com.fragile.honbook;

import android.app.ListActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import android.widget.TextView;

public class GuideSelection extends ListActivity{

private TextView selection;

private static final String[] heroes={ "Agility", "Intelligence",
    "Strength"};

public void onCreate(Bundle icicle){

    super.onCreate(icicle);

    setContentView(R.layout.heroselect);

    setListAdapter(new ArrayAdapter<String>(this,
            R.layout.row, R.id.label,
            heroes));

    selection=(TextView)findViewById(R.id.select);
}
    public void onListItemClick(ListView parent, View v,
                                int position, long id){
    }
}

Answer 1

public void onListItemClick(ListView parent, View v, position, long id){
  Intent intent = new Intent(GuideSelection.this, NewActivity.class);
  intent.putExtra("hero", heroes[position]);
  startActivity(intent);
}

Update (with different activities per list item):

final Map<String, Class> activities = new HashMap<String, Class>();

{
   activities.put("agility", AgilityActivity.class);
   activities.put("intelligence", IntelligenceActivity.class);
   // add more here
}

public void onListItemClick(ListView parent, View v, position, long id){
  Intent intent = new Intent(GuideSelection.this, activities.get(heroes[position]));
  intent.putExtra("hero", heroes[position]);
  startActivity(intent);
}
