Hello if i have understand your question you want to press a button, send the message to the second activity and display it to a textview. Add this code after textView3=(TextView)findViewById(R.id.textView3);

   String message="";
    if(getIntent().hasExtra("value1")){
        message = getIntent().getStringExtra("value1");
    }else if(getIntent().hasExtra("value2")){
        message = getIntent().getStringExtra("value2");
    }else{
        // no message passed to activity
    }

    textView3.setText(message);
