android arraylist筛选,Filter arraylist in java/android

Hello I need filter an ArrayList

I have a ArrayList with following items:

"Hello world"

"Hello man"

"Hello woman"

"Goodbye world"

"Goodbye man"

"Goodbye woman"

then on TextBox I added a textchanged listener (Android).What i want is if I write "he wo" separated by space, it displays "Hello world" and "Hello woman".

I've been fighting with this about an hour and only I got is that if I write "he wo" I get the following items: "Hello world", "Hello man", "Hello woman", "Goodbye world".

Here is the code

et.addTextChangedListener(new TextWatcher()

{

public void afterTextChanged(Editable s)

{

// Abstract Method of TextWatcher Interface.

}

public void beforeTextChanged(CharSequence s,

int start, int count, int after)

{

// Abstract Method of TextWatcher Interface.

}

public void onTextChanged(CharSequence s, int start, int before, int count)

{

//listabusClientes = new ArrayList();

paraulesBuscar = s.toString().split(" "); //Array of string

sortarray = new ArrayList(); //ArrayList of class busCliente

sortarray.clear();

for(int x = 0; x < paraulesBuscar.length; x++){

sortarray.clear();

for (int i = 0; i < listabusClientes.size(); i++)

{

if ((listabusClientes.get(i).getNom().toUpperCase().indexOf(paraulesBuscar[x].toUpperCase()) != -1) || (listabusClientes.get(i).getCodiClient().toUpperCase().indexOf(paraulesBuscar[x].toUpperCase()) != -1))

{

sortarray.add(listabusClientes.get(i));

}

}

}

lv.setAdapter(new ListViewAdapter(buscar_client.this,

R.layout.simple_list_item_1, sortarray));

}

});

Edited algorithm

paraulesBuscar = s.toString().split(" ");

sortarray = new ArrayList();

sortarray.clear();

for(int x = 0; x < paraulesBuscar.length; x++){

sortarray.clear();

for (int i = 0; i < listabusClientes.size(); i++)

{

String[] clientSplit = listabusClientes.get(i).getNom().split(" ");

for(int cs = 0; cs < clientSplit.length; cs++){

System.out.println(clientSplit[cs]);

if (clientSplit[cs].toUpperCase().contains(paraulesBuscar[x].toUpperCase()))

{

sortarray.add(listabusClientes.get(i));

}

}

}

}
