我根据需要构建了一个三个 sqlite 表。

1.登录

在此处输入图像描述

2.列表

在此处输入图像描述

3.备忘录

在此处输入图像描述

在我的表中，我将登录 id(id) 值从第一个表传递到显示 id2 的第二个表。

现在我想将 id 值从表 2 传递到 id2 下的表 3。

我尝试使用来自游标的意图传递值，但我没有得到任何值。它只显示零。

任何人都可以从我的代码中找出错误。

我的代码

1.class 显示第三个表的详细信息

public class addmemo extends Activity{
EditText memtitle, content;

在您的适配器类中，您将传递给类名 memo.class

 v.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        Intent intent = new Intent(context, memo.class).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.putExtra("id",id );
        Log.d("ci", String.valueOf(id));
        intent.putExtra("id1", id1);
        Log.d("ci1", String.valueOf(id1));
        context.startActivity(intent);
    }
});

并且您在其他一些类中获得了这些捆绑包值

public class addmemo extends Activity

更好的是，您可以将这些捆绑值传递给 memo.class 并使用共享首选项您可以将值传递给您的 addmemo 类。
