                }
            }
        });
    }
}

I need help here!

I created MainActiviy and a second Activity called Game. I want to send EditText nama to the second Activity. I want to use nama in my second activity.

Thanks in advance

What is the purpose of using "nama" in second activity? If you only want the value of edittext, then you can send the value of edittext as a string in the intent used to call second activity and then get the value from bundle in the second activity, then use it. — Madhan, Oct 19 '16 at 03:14
Kau boleh ganti `equals()` dengan `equalsIgnoreCase()` supaya mana2 huruf besar akan diabaikan, tak perlu declare banyak kali macam "Fredy", "fRedy", "frEdy" — Fay Zan, Oct 21 '16 at 02:04

Pass it in bundle like below .

private void addListenerButton_OK() {
    nama=(EditText)findViewById(R.id.editText_NamaAnda);
    OK=(Button)findViewById(R.id.button_OK);
    OK.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(nama.getText().toString().equals("Fredy")||nama.getText().toString().equals("Oktafianus")||nama.getText().toString().equals("Markus")
                    ||nama.getText().toString().equals("fredy")||nama.getText().toString().equals("oktafianus")||nama.getText().toString().equals("markus")){
                Intent Clicked_OK=new Intent(MainActivity.this,Game.class);
                Clicked_OK.putExtra("NAME", nama.getText());
                startActivity(Clicked_OK);
            }else{

                Toast.makeText(getBaseContext(),"Error : "+nama.getText()+" Bukan nama depan anda!",Toast.LENGTH_LONG).show();
            }
        }
    });
}

Then in game activity OnCreate method, get name like this ,

 Intent intent = getIntent();
    if(intent!=null){
        Bundle bundle = intent.getExtras();
        String name  = bundle.getString("NAME");
    }

Try this,

Intent Clicked_OK = new Intent(MainActivity.this, Game.class);
Clicked_OK.putExtra("nama",nama.getText().toString());
startActivity(Clicked_OK);

On Game class onCreate method get "nama" from this way,

String nama =  getIntent().getExtras().getString("nama");

An Intent is a messaging object you can use to request an action from another app component.

Extras Key-value pairs that carry additional information required to accomplish the requested action.
