Question

我有两个EditTexts，一个用于输入密码，另一个用于确认此密码。这些edittexts的最大长度为5。

confirmPwdEdiText.addTextChangedListener(new TextWatcher() {
 public void afterTextChanged(Editable s) {}
 public void beforeTextChanged(CharSequence s, int start, int count,
     int after) { }

 public void onTextChanged(CharSequence charSequence, int start, int before, int count)        
 {

   String pwd = passwordEdiText.getText().toString();
   String confirmaion = charSequence.toString();
   if ((pwd == null || pwd.trim().length() <= 0) &&  confirmaion.trim().length() > 0) {
           Toast.makeText(context,"Enter password",Toast.LENGTH_SHORT).show();
   } 
   else if (pwd != null && pwd.trim().length() > 0 ) {
      if(confirmaion.trim().length() == pwd.length()) {
         if (pwd.equals(confirmaion)) {
            password = pwd;
            Toast.makeText(context,"Passwords match",Toast.LENGTH_SHORT).show();
         } 
         else {
            Toast.makeText(context,"Passwords do not match",Toast.LENGTH_SHORT).show();
         }
      }
   }
 }
});

当我使用此确认密码时，删除密码时会再次显示“密码不匹配”吐司。如何以有效的方式确认密码而不使用按钮点击或任何其他？

先谢谢

Answer 1

您可以添加一个按钮，并按下onClick Listener按钮验证您的密码。

Answer 2

您可以使用TextWatcher

et1.addTextChangedListener(new TextWatcher() {
            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

                // TODO Auto-generated method stub
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                // TODO Auto-generated method stub
            }

            @Override
            public void afterTextChanged(Editable s) {

                // TODO Auto-generated method stub
            }
        });

参考这个简单的样本，你会得到线索如果两个字符串都不为null或为空，则将旧密码与新密码进行比较的简单逻辑，如果检查旧密码长度和新密码长度并比较两个密码，则其他情况相同。

如果您选择简单验证

，则可以使用此选项

    @Override
public void afterTextChanged(Editable s) {

    System.out.println(s.toString());
    String oldPass = oldPassword.getText().toString();
    String newPass = newPassword.getText().toString();
    String confirmPass = confirmPassword.getText().toString();
    if (!oldPass.equals("") && !newPass.equals("") && oldPass.equals(newPass)) {
        Toast.makeText(getContext(), "Choose Different Password than Old Password", Toast.LENGTH_SHORT).show();
    }
    else if (!newPass.equals("") && !confirmPass.equals("") && !newPass.equals(confirmPass) && newPass.length()==confirmPass.length())
    {
        Toast.makeText(getContext(), "Choose same as New Password", Toast.LENGTH_SHORT).show();
    }
}

试试这个

        private boolean checkPasswordNotMatch() {
            String pass=signupInputPassword.getText().toString();
            String cpass=signupInputPassword2.getText().toString();
            if (!pass.equals(cpass)) {
                signupInputLayoutPassword2.setErrorEnabled(true);
                signupInputLayoutPassword2.setError(getString(R.string.err_msg_password_confirm));
                signupInputLayoutPassword.setErrorEnabled(true);
                signupInputLayoutPassword.setError(getString(R.string.err_msg_password_confirm));
                return false;
        }
            signupInputLayoutPassword.setErrorEnabled(false);
            return true;
        }
