Sqlite数据库将值传递给多个Android表？
我根据需要构建了一个三个sqlite表。
1.登陆
2.list
3.memo
在我的表中，我将登录ID（id）值从第1个表传递给显示id2的第二个表。
现在我想将id值从表2传递到id2下的表。
我试过通过游标使用intent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;
Button add, cancel;
int id1;
String title;
int id;

cancel = (Button) findViewById(R.id.canmembuttn);

答案 0 :(得分：0)
在适配器类中，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);
}
});
并且您将在其他类
中获取这些包值public class addmemo extends Activity
您可以将这些包值传递给memo.class并使用共享首选项，您可以将值传递给addmemo类。
