Try this code.

Intent myIntent = null;
if(password.getText().toString().equals("admin")) {
System.out.println("Entering");
mapView.setVisibility(View.VISIBLE);
login.setVisibility(View.INVISIBLE);
password.setVisibility(View.INVISIBLE);
myIntent = new Intent(GMapsActivity.this, GMapsActivity1.class);
startActivity(myIntent);
} else {
Toast.makeText(context, "password is invalid",  Toast.LENGTH_SHORT).show();
}
