ImageView iv;
ListView lv;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.cover);

//-------
data.add("India");
data.add("US");
data.add("Pak");
filterText = (EditText) findViewById(R.id.searchbox);
filterText.addTextChangedListener(filterTextWatcher);
adapter = new ArrayAdapter<String>(this,
R.id.top,
data);
//-------


m_orders = new ArrayList<Order>();
this.m_adapter = new OrderAdapter(this, R.layout.row,
m_orders);
setListAdapter(this.m_adapter);


viewOrders = new Runnable(){

@Override
public void run() {
getOrders();
}
};
Thread thread = new Thread(null, viewOrders,
"MagentoBackground");
thread.start();
m_ProgressDialog =
ProgressDialog.show(Listitems.this,
"Please wait...", "Retrieving data ...", true);

//------------

lv = (ListView) findViewById(android.R.id.list);
lv.setTextFilterEnabled(true);
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
((TextView)arg1.findViewById(R.id.toptext)).getText() ,
Toast.LENGTH_SHORT).show();

}
});

}
private TextWatcher filterTextWatcher = new TextWatcher() {

public void afterTextChanged(Editable s) {
//adapter.getFilter().filter(s);
}

public void beforeTextChanged(CharSequence s, int start, int
count,
int after) {
}

public void onTextChanged(CharSequence s, int start, int
before,
int count) {
adapter.getFilter().filter(s);
/* String text=filterText.getText().toString();
System.out.println(data.get(0));
System.out.println(text);

for(int k=0;k<data.size();k++) {
