Retrieving the intent values from another class

My question is a bit basic. I've been learning to code on JAVA and android. Here I am a bit confused on how to call the values that I have sent via an intent.

In my first activity this is the intent that I am using.

            Intent intent = new Intent(MainActivity.this, Secondactivity.class);
            String regName1 = regName;
            intent.putExtra(regName1, regNameSplit[0]);
            startActivity(intent);

Here regName1 will contain three values. SessionID,URL,Name split by "-".

In my SecondActivity

public class Secondactivity extends Activity {
public final String TAG = "###---Secondactivity---###";
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-gen开发者_运维问答erated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.secondactivity);
    Log.i(TAG,"before if statement");
    if (getIntent().getStringExtra("regName1") != null){
        getIntent().getStringExtra("regName1").split("-");
        String[] str = "regName";
        Log.i(TAG, ""+str[0]+str[1]+str[2])
    }
}

}

The value if regName1 always comes as null.

This line

intent.putExtra(regName1, regNameSplit[0]);

Needs to be like this instead

intent.putExtra("regName1", regNameSplit[0]); // note the quotes

BUT you are using regName1 as a variable... how do you expect the second class to know that variable?

Use a string resource instead.

and you are sure that the content of the variable regName is actually "regName"? cause you set the value using

intent.putExtra(regName, ... )

and you get the value using

intent.getStringExtra("regName")

use firstactivity

dont use

String regname1=regname;

just: intent.putExtra("regName1", regNameSplit[0]);

in second Activity

if (getIntent().getStringExtra("regName1") != null){ // }
