推荐答案

RC_SIGN in是您将分配用于启动新活动的请求代码。这可以是任何数字。当用户完成后续活动并返回时，系统会调用您的活动的onActivityResult（）方法。并且该方法将如下所示：

RC_SIGN in is the request code you will assign for starting the new activity. this can be any number. When the user is done with the subsequent activity and returns, the system calls your activity's onActivityResult() method. and that method will be like :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
    if (requestCode == RC_SIGN) {

    }
}
