我正在登录屏幕上，它包含两个EditText，当我在android studio中运行该应用程序时，出现错误
android.view.InflateException: Binary XML file line #37: Binary XML file line #37: Error inflating class EditText
这是日志错误的第一行

提示到xml文件的37行，它是一个EditText，但是我发现EditText没错。 xml布局文件没有给我关于任何属性错误或错字的错误。日志除了指向该行之外没有提供很多信息
setContentView(R.layout.activity_main);
继承人的班级
package org.techgeorge.loginscreen;
public class MainActivity extends AppCompatActivity {
private TextView titleTextView, registerTextView, forgetPassTextView;
private EditText usernameEditText, passwordEditText;
private ImageView logoImageView;
private Button loginButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
titleTextView = findViewById(R.id.title_textview);
registerTextView = findViewById(R.id.register_textview);
forgetPassTextView = findViewById(R.id.forget_password_textview);
usernameEditText = findViewById(R.id.user_edittext);
passwordEditText = findViewById(R.id.password_edittext);
logoImageView = findViewById(R.id.logo_imageview);
loginButton = findViewById(R.id.button);
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getApplicationContext(), ProfileActivity.class);
startActivity(intent);
}
});
}
}
这是xml布局类activity_main.xml

我也经历过同样的事情，我认为它是一个错误，让我们先删除它，然后再重写
