我正在存储令牌和放大器sqlite中的userId，其中包含以下一项活动：
名称 - 获取“userId”＆amp;存储在sqlite数据库中的“令牌”。
SQLiteHandler - 存储“userID”＆amp; “令牌”。
注册 - 在此活动中，我想获取“userId”＆amp; “token”，它已经通过Name活动存储在Sqlite中。
我该怎么做？

答案 0 :(得分：0)
要将数据传递给另一个Activity，您可以像这样实现
Intent intent = new Intent(Name.this, SignUP.class);
intent.putExtra("id", id);
intent.putExtra("token",token);
startActivity(intent);
接收 SignUp
int id,token // declare them in global
id = getIntent().getIntExtra("id",0);
token = getIntent().getIntExtra("token",0);
