    public class SingleMenuItem extends Activity{
static final String KEY_TITLE = "title";
static final String KEY_COST = "cost";
static final String KEY_THUMB_URL = "imageUri";
private EditText edit_qty_code;
private TextView txt_total;
private TextView text_cost_code;
private double itemamount = 0;
private double itemquantity = 0;
ListView list;
LazyAdapter adapter;
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.single);

    Intent in = getIntent();
    String title = in.getStringExtra(KEY_TITLE);
    String thumb_url = in.getStringExtra(KEY_THUMB_URL);
    String cost = in.getStringExtra(KEY_COST);

    ImageLoader imageLoader = new ImageLoader(getApplicationContext());

    ImageView imgv = (ImageView) findViewById(R.id.single_thumb);
    TextView txttitle = (TextView) findViewById(R.id.single_title);
    TextView txtcost = (TextView) findViewById(R.id.single_cost);
    TextView txtheader = (TextView) findViewById(R.id.actionbar);

    txttitle.setText(title);
    txtheader.setText(title);
    txtcost.setText(cost);
    imageLoader.DisplayImage(thumb_url, imgv);

    text_cost_code = (TextView)findViewById(R.id.single_cost);
    edit_qty_code = (EditText)findViewById(R.id.single_qty);
    txt_total=(TextView)findViewById(R.id.single_total);

    itemamount=Double.parseDouble(text_cost_code.getText().toString());
    txt_total.setText(Double.toString(itemamount));

    edit_qty_code.addTextChangedListener(new TextWatcher() {

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


    // TODO Auto-generated method stub
    }
    public void beforeTextChanged(CharSequence s, int start, int count,
    int after) {

    // TODO Auto-generated method stub
    }
    public void afterTextChanged(Editable s) {
         itemquantity=Double.parseDouble(edit_qty_code.getText().toString());
         itemamount=Double.parseDouble(text_cost_code.getText().toString());
         txt_total.setText(Double.toString(itemquantity*itemamount));
    }
    });             

    final ArrayList<HashMap<String, String>> itemsList = 
    new ArrayList<HashMap<String, String>>();
    list=(ListView)findViewById(R.id.listView1);            
    adapter=new LazyAdapter(this, itemsList);        
    list.setAdapter(adapter);



    ImageButton addToCartButton = (ImageButton) findViewById(R.id.img_add);
    addToCartButton.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {    



  int position = 0;
HashMap<String, String> map = itemsList.get(position);

    Intent in = new Intent
         (SingleMenuItem.this, com.erachnida.restaurant.versionoct.FinalOrder.class);
    in.putExtra(KEY_TITLE, map.get(KEY_TITLE));
    in.putExtra(KEY_COST, map.get(KEY_COST));
    startActivity(in);
}


   });  


    // Close the activity
   //  finish();

   }}

ViewCart:-

public class FinalOrder extends Activity
{
static final String KEY_TITLE = "title";
static final String KEY_COST = "cost";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view);     


Intent in = getIntent();

String title1 = in.getStringExtra(KEY_TITLE);
String cost1 = in.getStringExtra(KEY_COST);

TextView txttitle1 = (TextView) findViewById(R.id.item_name);
TextView txtcost1 = (TextView) findViewById(R.id.item_cost);

txttitle1.setText(title1);
txtcost1.setText(cost1);    

}

Write below Code to get data from intent, it will solve your problem.

Bundle bdl=getIntent().getExtras();
String title1 = bdl.getString(KEY_TITLE);
String cost1 = bdl.getString(KEY_COST);
