Just show the toast on the current activity.

But if you really want to show the toast on second activity, you can just throw the intent on the second activity. You can do this by following code:

else{
  Intent intent = new Intent(this,SecondActivity.class);
  startActivity(intent);
}

Then on the SecondActivity just create a toast which displays the message :

Toast.makeText(this, "UserName or Password invalid",Toast.LENGTH_SHORT).show();

If you start second just to display an error toast message, don't do it. You can display toast message in the current activity. If second activity contains some other logic then you can use next code:

In the current activity:

Intent intent = new Intent(getContext(), SecondActivity.class)
                      .putExtra("show_toast", true);
startActivity(intent);

In the second activity's onCreate() method:

if (getIntent().hasExtra("show_toast") && getIntent().getBooleanExtra("show_toast", false)) {
    Toast.makeText(getContext(), "UserName or Password invalid", Toast.LENGTH_SHORT).show();
}

first open second activity using following code

else
{
  Intent in = new Intent(this,SecondActivity.class);
  startActivity(in);
}

following code write in your seconde activity

Toast.makeText(getApplicationContext, "UserName or Password invalid",Toast.LENGTH_SHORT).show();
