Activity中调用 自定义LinearLayout布局文件方法

Question

public class LoginActivity extends BaseActivity {

    private  LoginView  mLoginView;
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        this.mLoginView = new LoginView(this);
        this.mLoginView.setDataShowPage(this.mType);
    }
}


public class LoginView extends LinearLayout {

    private TextView tv_bind_switch;

    public LoginView(Context context) {
        super(context);
        this.activity = (Activity) context;
        initView();
    }

    public LoginView(Context context, @Nullable AttributeSet attributeSet) {
        super(context, attributeSet);
        this.activity = (Activity) context;
        initView();
    }

    public LoginView(Context context, @Nullable AttributeSet attributeSet, int i) {
        super(context, attributeSet, i);
        this.activity = (Activity) context;
        initView();
    }

    public void initView(){
        LayoutInflater.from(this.activity).inflate(R.layout.view_login_layout,this);
        this.tv_bind_switch = findViewById(R.id.tv_bind_switch)
    }

    public void setDataShowPage{
        this.tv_bind_switch.setVisibility(View.GONE);
    }
}       

//已经初始化的LinearLayout，外部调用更改内部布局，不生效怎么办

你都没有setContentView何谈生效？
