步骤1：使用注解

@NotEmpty
@Email
private EditText emailEditText;

@Password(min = 6, scheme = Password.Scheme.ALPHA_NUMERIC_MIXED_CASE_SYMBOLS)
private EditText passwordEditText;

@ConfirmPassword
private EditText confirmPasswordEditText;

@Checked(message = "You must agree to the terms.")
private CheckBox iAgreeCheckBox;

步骤2：监听验证

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Code…

Validator validator = new Validator(this);

validator.setValidationListener(this); // More code…}

步骤3:实现监听接口：

public class RegistrationActivity extends Activity implements ValidationListener {

    // Code…

    @Override
    public void onValidationSucceeded() {
        Toast.makeText(this, "Yay! we got it right!", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onValidationFailed(List<ValidationError> errors) {
        for (ValidationError error : errors) {
            View view = error.getView();
            String message = error.getCollatedErrorMessage(this);

            // Display error messages ;)
            if (view instanceof EditText) {
                ((EditText) view).setError(message);
            } else {
                Toast.makeText(this, message, Toast.LENGTH_LONG).show();
            }
        }
    }
}

步骤4：验证结果注册按钮

registerButton.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        validator.validate();
    }
});

登录验证示列：

@Length(min = 6,message = "账号不能少于6位")
    private EditText userName;
    @Length(min = 8, max = 16,message = "密码不能少于8位或大于16位")
    private EditText passWord;

 private Validator validator;

        validator = new Validator(this);
        validator.setValidationListener(this);

 @Override
    public void onValidationSucceeded() {
                removeVerify();
    }

    @Override
    public void onValidationFailed(List<ValidationError> errors) {
        for (ValidationError error : errors) {
            View view = error.getView();
            String message = error.getCollatedErrorMessage(this);

            // Display error messages ;)
            if (view instanceof TextInputEditText) {
                ((TextInputEditText) view).setError(message);
            } else {
                Toast.makeText(this, message, Toast.LENGTH_LONG).show();
            }
        }
    }

 case R.id.sure_login:
                validator.validate();
                break;
