帮忙看个简单的异常

[新靖界]

03-01 17:54:25.752: E/AndroidRuntime(31014): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.csw.community_shopping/com.csw.members.RegisterActivity}: java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.EditText

不只到为什么，老是报这个错，代码没错啊，也clean了。
代码：

private EditText usernameEditText;
	private EditText passwordEditText ,passwordConfirmEditText, emailEditText;// 声明用户名、密码、email框框
	private Button registerBtn, resetBtn;// 声明注册、清空按钮
	private static String usernameInputStr, passwordInputStr,
			passwordConfirmStr, emailInputStr;// 声明得到的值

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.register);
		initWidget();
	}
	private void initWidget() {
		usernameEditText = (EditText) this
				.findViewById(R.id.usernameInputTextRegister);
		passwordEditText = (EditText) this
				.findViewById(R.id.passwordTitleRegister);
		passwordConfirmEditText = (EditText) this
				.findViewById(R.id.passwordConfirmInputText);
		emailEditText = (EditText) this.findViewById(R.id.emailInputText);

调试运行到usernameEditText = (EditText) this
.findViewById(R.id.usernameInputTextRegister);这就就报这错了

请各位帮忙看下是哪出问题了，谢谢！

[哎，真难]

把这个绑定ID的事件放到Oncreate里面试试，别写在方法里面

解决了 passwordEditText = (EditText) this .findViewById(R.id.passwordTitleRegister);应该改成passwordEditText = (EditText) this .findViewById(R.id.passwordInputTextRegister); 是我引用错了，名字太像了！
