public class Test extends ListActivity implements OnScrollListener {

    Aleph0 adapter = new Aleph0();

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setListAdapter(adapter); 
        getListView().setOnScrollListener(this);
    }

    public void onScroll(AbsListView view,
        int firstVisible, int visibleCount, int totalCount) {

        boolean loadMore = /* maybe add a padding */
            firstVisible + visibleCount &gt;= totalCount;

        if(loadMore) {
            adapter.count += visibleCount; // or any other amount
            adapter.notifyDataSetChanged();
        }
    }

    public void onScrollStateChanged(AbsListView v, int s) { }    

    class Aleph0 extends BaseAdapter {
        int count = 1; /* starting amount */

        public int getCount() { return count; }
        public Object getItem(int pos) { return pos; }
        public long getItemId(int pos) { return pos; }

        public View getView(int pos, View v, ViewGroup p) {
                TextView view = new TextView(Test.this);
                view.setText("List Item " + pos);
                return view;
        }
    }
}

public class Test extends ListActivity implements OnScrollListener {

Aleph0 adapter = new Aleph0();

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setListAdapter(adapter);

getListView().setOnScrollListener(this);

}

public void onScroll(AbsListView view,

int firstVisible, int visibleCount, int totalCount) {

boolean loadMore = /* maybe add a padding */

firstVisible + visibleCount >= totalCount;

if(loadMore) {

adapter.count += visibleCount; // or any other amount

adapter.notifyDataSetChanged();

}

public void onScrollStateChanged(AbsListView v, int s) { }

class Aleph0 extends BaseAdapter {

int count = 1; /* starting amount */

public int getCount() { return count; }

public Object getItem(int pos) { return pos; }

public long getItemId(int pos) { return pos; }

public View getView(int pos, View v, ViewGroup p) {

TextView view = new TextView(Test.this);

view.setText("List Item " + pos);

return view;

}

This will create a list integers. On reaching the end of list next 10 will be loaded into list. This is efficient way to load chunks of items in a long list.

This functions returns the input string padded on the left, the right, or both sides to the specified padding length. If the optional argument pad_string is not supplied, the input is padded with spaces, otherwise it is padded with characters from pad_string up to the limit.

&lt;?php
$input = "Hello";
echo str_pad($input, 10);                      // produces "Hello     "
echo str_pad($input, 10, "-=", STR_PAD_LEFT);  // produces "-=-=-Hello"
echo str_pad($input, 10, "_", STR_PAD_BOTH);   // produces "__Hello___"
echo str_pad($input, 6 , "___");               // produces "Hello_"
?&gt;

<?php

$input = "Hello";

echo str_pad($input, 10); // produces "Hello "

echo str_pad($input, 10, "-=", STR_PAD_LEFT); // produces "-=-=-Hello"

echo str_pad($input, 10, "_", STR_PAD_BOTH); // produces "__Hello___"

echo str_pad($input, 6 , "___"); // produces "Hello_"
