android - How can I implement a ListView without ListActivity? (use only Activity)

Question

I'm new to Android, and I really need to do it this way (I've considered doing it in another Activity), but can anyone show me a simple code (just the onCreate() method) that can do Listview without ListActivity?

THanks

If you have an xml layout for the activity including a listView like this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent" 
android:layout_height="fill_parent">

<ListView android:id="@android:id/list"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:layout_weight="fill_parent"

Then in your onCreate you could have something like this

setContentView(R.layout.the_view);
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, myList);
ListView lv = (ListView)findViewById(android.R.id.list);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener()
{
     @Override
     public void onItemClick(AdapterView<?> a, View v,int position, long id) 
     {
          Toast.makeText(getBaseContext(), "Click", Toast.LENGTH_LONG).show();
      }
});
