// 为点菜列表ListView绑定数据的方法
private void setMenusAdapter(){

// 获得EditText，CODE
EditText code_et = (EditText)findViewById(R.id.editText1);

//cr.query(uri1, projection, selection, selectionArgs, sortOrder);
// 获得ContentResolver实例
ContentResolver cr = getContentResolver();
// 访问数据的Uri
Uri uri1 = Tables.CONTENT_URI;
// 删除本地SQLite数据库中菜谱表中的数据
// 要选择桌号表中的列
final Cursor c = cr.query(uri1, projection, selection, null, null);

// System.out.println(c);
// 获得LayoutInflater实例
LayoutInflater inflater = LayoutInflater.from(this);
// 实例化在弹出对话框中添加的视图
final View v = inflater.inflate(R.layout.listview, null);
// 获得TextView，菜价格

// 获得TextView，菜名称

// 菜价格值

// 菜名称值
String nameStr = name_tv.getText().toString();
c.close();
// 装到Map中
map = new HashMap();
map.put("code", codeStr);

//
// 添加到ListView
data.add(map);
// 关联的TextView
to[0] = R.id.code_ListView;
to[1] = R.id.fenshu_ListView;
to[2] = R.id.jiaqian_ListView;
to[3] = R.id.mingzi_ListView;
// 实例化SimpleAdapter
sa = new SimpleAdapter(JiacaiActivity.this, data, R.layout.listview,
from, to);
// 为ListView绑定数据
lv.setAdapter(sa);
sa.notifyDataSetChanged();
Toast.
makeText(JiacaiActivity.this, " priceStr "+priceStr+"nameStr"+nameStr, Toast.LENGTH_LONG).show();
}
这里priceStr nameStr是空的 但是code份数有显示
