Butterknife: java.lang.RuntimeException: Caused by: java.lang.ClassCastException: android.support.v7.widget.AppCompatTextView cannot be cast to android.app.Activity

It seems that I can create 1 activity perfectly, however starting a new one causes a crash.

LoginActivity:

 @BindView(R.id.input_username)
    EditText _usernameText;

  @BindView(R.id.register_button)
      TextView register_button;

 @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_login);

         ButterKnife.bind(this);

       register_button.setOnClickListener(new View.OnClickListener(){
               @Override
               public void onClick(View v){
                  Intent intent = new Intent(getApplication(), RegisterActivity.class);
                  startActivity(intent);
              }
          });
      }

And my register activity:

@BindView(R.id.input_username_register)
    EditText _usernameText;

    @BindView(R.id.input_email_register)
    EditText _emailText;

    @BindView(R.id.input_password_register)
    EditText _passwordText;

    @BindView(R.id.login_button_register)
    Button login_button;

    @BindView(R.id.register_button_register)
    TextView register_button;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register);

        ButterKnife.setDebug(true);
        ButterKnife.bind(this);
        Injector.inject(this);

        register_button.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                register();
            }
        });

        login_button.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                Intent intent = new Intent(getApplication(), LoginActivity.class);
                startActivity(intent);
            }
        });
    }

I have solved the issue myself, I messed up between the Button and TextView with the @BindView

This caused a failed cast, which crashed everything. Debugging it was a bit weird, as the line debugger wasn't that helpful at all. But fixed it now!
