Why can't I get the extra that I put on my main activity

Issue

I have put extra with this code on my main activity like this:

Intent intent = new Intent();
intent.setClass(ItemMainActivity.this, (Class<?>) map.get("itemActivity"));
intent.putExtra("user",user);
intent.putExtra("userID",userID);
startActivity(intent);

When I try to get the extra by using this code, it returns null:

Intent intent = this.getIntent();
Bundle extras = intent.getExtras();
String user = null, userID = null;
if (extras != null) {
    user = extras.getString("user");
    userID = extras.getString("userID");
}
Toast.makeText(getApplicationContext(),"user: "+user+" id: "+userID,Toast.LENGTH_LONG).show();

How do I fix this?

Solution

I would like to suggest another way.... The concept of a common class. And make a public static variable of the data type which you need and set the value in the activity and access it wherever you need.

Public class Common{
    Public static String userId ="";
      }

Set value in this variable Common.userId = "YOUR_VALUE" When need to access just use Common.userId

Feel free to ask if something is unclear.
