Question

想要使用标签主机让我的页面更灵活..这是我的情况例如，我有学生信息表格，有足够可控制的控件，所以想在选项卡中划分页面。

标签1将包含学生个人详细信息，例如姓名年龄DOB等
标签2将包含学生学校的详细信息，例如学校nm，标准，科目
Tab 3将有他的课外活动细节，如成就，兴趣爱好

以前它只在一个页面中;在一个活动中有代码并单击提交按钮会将页面保存在一个名为studentTbl.sqlite的数据库表中

现在想要使用3个标签，每个标签带有下一个按钮，结束标签将有提交按钮，这将保存所有3个标签数据，保存点击studentTbl.sqlite

那么如何为单表保存实现这种单页活动的标签主机？

Answer 1

创建一个新活动 Const.java 并添加以下代码。

public class Const {
    public static String name;
    public static String age;
    public static String dob;
    public static String schoolname;
    public static String std;
    public static String sub;
             ...
             ...
}

现在在第一个活动中，下一个按钮点击事件使用下面的代码。

next.setOnClickListener(new ImageView.OnClickListener()
    {
        public void onClick(View v) 
        {

           Code.name= editTextName.getText().toString().trim();
           Code.age= editTextAge.getText().toString().trim();
                  .......
                  .......
        }
   });

然后对所有活动（第二个活动）都相同，如果你想添加更多屏幕，那么在最后一个屏幕的提交按钮中获取这个全局变量值并将其传递给数据库。

希望它会对你有所帮助。如果你有任何问题，请让我知道......

此示例代码可以帮助您......
