public class AddtoCart extends Activity{
static final String KEY_TITLE = "title";
static final String KEY_COST = "cost";
static final String KEY_THUMB_URL = "imageUri";
@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);
txttitle.setText(title);
txtcost.setText(cost);
imageLoader.DisplayImage(thumb_url, imgv);
// Save a reference to the quantity edit text
final EditText editTextQuantity = (EditText) findViewById(R.id.edit_qty);
ImageButton addToCartButton = (ImageButton) findViewById(R.id.img_add);
addToCartButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Check to see that a valid quantity was entered
int quantity = 0;
try {
quantity = Integer.parseInt(editTextQuantity.getText()
.toString());
if (quantity <= 0) {
Toast.makeText(getBaseContext(),
"Please enter a quantity of 1 or higher",
Toast.LENGTH_SHORT).show();
return;
}
} catch (Exception e) {
Toast.makeText(getBaseContext(),
"Please enter a numeric quantity",
Toast.LENGTH_SHORT).show();
