Java 当我按下从数据库检索数据的更新按钮时，如何立即更改TextView的值？

//此变量转到（TextInputLayout“fullNameInput”）和（TextView fullName）。此变量用于更新用户的全名，也是摩托车品牌。它应同时更新TextView（全名和摩托车）同时从数据库中检索数据，只要我单击表单下方的更新按钮，它就会立即更新。但它仅在新登录后更新。（数据库的表名为users，第一个子项为用户名）

你想尝试什么是不可理解的你不明白@ashis你的onclicklistener不工作吗？不，我的onclicklistener工作正常，因为它更新了数据库上的数据。并将更新的数据保存在TextInputLayouts上。唯一的问题是它不更新我的两个TextView。你能看到附件中的图像吗？然后你可以nt是否也要在单击时更改数据？

public class UserprofileActivity extends AppCompatActivity {

    // VARIABLES
    TextView fullName, userName, location, motorcycle;
    TextInputLayout fullNameInput, emailInput, motorcycleInput, passwordInput;

    // GLOBAL VARIABLES TO HOLD USER DATA INSIDE THIS ACTIVITY
