Java 在android中获取按钮单击事件时出错

我在android中生成了一个点击事件，我用这种方式编写了代码

public class LoginActivity extends AppCompatActivity {
    Button btnLogin;
    EditText inputEmail,inputPassword;
    protected String enteredEmail;
    String enteredPassword;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
       // inputEmail = (EditText) findViewById(R.id.email);
       // inputPassword = (EditText) findViewById(R.id.password);
         btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(getApplicationContext(), HomeActivity.class);
                startActivity(i);
            }});}

但是得到下面的错误

TextInputLayout: EditText added is not a TextInputEditText. Please

如何解决此错误？

您缺少初始化

按钮

btnLogin = (Button) findViewById(R.id.Set_Button_Id);

喜欢

 btnLogin = (Button) findViewById(R.id.Set_Button_Id);
    btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(getApplicationContext(), HomeActivity.class);
                startActivity(i);
            }});}

您缺少初始化
按钮

btnLogin = (Button) findViewById(R.id.Set_Button_Id);

喜欢

 btnLogin = (Button) findViewById(R.id.Set_Button_Id);
    btnLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent i = new Intent(getApplicationContext(), HomeActivity.class);
                startActivity(i);
            }});}

请像这样初始化按钮btnLogin=（按钮）findViewById（R.id.login\u btn\u id）；请像这样初始化按钮btnLogin=（按钮）findViewById（R.id.login\u btn\u id）；
