我正在制作一个应用程序,其中我使用json解析器将数据提取到listview中,然后将所选列表视图项目行显示到具有项目详细信息的另一个活动(注意: - 我从ListView活动获取到singleItem活动的详细信息)现在我需要通过使用singleItem活动上的“添加到购物车”按钮将所有选定项目的项目标题和成本显示到另一个活动ie-ViewCart(从singleItem Activity到ViewCart Activity),以将所有选定记录发送到ViewCart活动,如: - 购物车功能添加到购物车然后将整个选定的记录查看到另一个活动ViewCart,我只是想显示所选项目的标题和成本到另一个活动,仍然我只显示一个选定的项目而不是所有选定的项目由用户在会话,我也没有保存完整会话的记录,但现在我想根据完整的会话,按用户将所有选定的项目显示到viewcart活动。 下面我将放置singleItem和ViewCart代码: -
SingleItem代码: -
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;
@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));
}
});
ImageButton addToCartButton = (ImageButton) findViewById(R.id.img_add);
addToCartButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent in = new Intent
(SingleMenuItem.this, com.erachnida.restaurant.versionoct.FinalOrder.class);
in.putExtra(KEY_TITLE, getIntent().getStringExtra(KEY_TITLE));
in.putExtra(KEY_COST, getIntent().getStringExtra(KEY_COST));
startActivity(in);
// Close the activity
// finish();
}
});
}}
ViewCart代码: -
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);
}
}

使用以下代码删除您的onclick代码。
public void onClick(View v) {
Intent in = new Intent
(SingleMenuItem.this, com.erachnida.restaurant.versionoct.FinalOrder.class);
in.putExtra(KEY_TITLE, title);
in.putExtra(KEY_COST, cost);
startActivity(in);
// Close the activity
// finish();
}
