齐射响应方法内的代码

I am developing an android app using php and mysql. This login has a restriction where only active users can logged in. In mysql table column active is set to 1 or 0 for active and inactive, respectively. The problem here is when the value of active is set to 1, it displays not active. Here's my code below

What I have tried:

Code inside volley response method

String userId = jObj.getString("user_id");
String userType = jObj.getString("type");
String userActive = jObj.getString("active");

if (userId != "null") {

    switch (userType)
    {
    case "1":
        Toast.makeText(getApplicationContext(),"Access Denied", Toast.LENGTH_LONG).show();
        break;
    default:
        session.setLogin(true);
        session.setType(userType,userId);
        if(userActive=="1"){
            Intent dashB = new Intent(login_activity.this,MainDashBoard.class);
            startActivity(dashB);
            finish();
        }
        else{
            Toast.makeText(getApplicationContext(),"Not active", Toast.LENGTH_LONG).show();
        }
        break;
    }
} else {
    String errorMsg = jObj.getString("error_msg");
    Toast.makeText(login_activity.this,"Invalid Username or Password", Toast.LENGTH_LONG).show();

推荐答案

你不应该使用 == 字符串运算符，使用 String.equals [ ^ ]。

You should not use the == operator for strings, use String.equals[^].
