Android字段驗證的實例代碼

先給大家展示效果圖：

import android.app.Activity; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button;

@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 
initView(); 
setListener(); 
validateForm(); 
} 
//格式驗證 
private void validateForm() { 
// 1. 先創建個表單Form類用來裝控件 
form = new Form(); 
// 非空驗證 
// 2. 然後創建Validate類，將被驗證控件傳入 
Validate notEmptyValidate = new Validate(etAccount); 
// 3. 將這個Validate類addValidator加入（如：非空類型NotEmptyVerifior）類型驗證類 
NotEmptyValidator notEmpty = new NotEmptyValidator(this); 
notEmptyValidate.addValidator(notEmpty); 
// 二選一 
OrTwoRequiredValidate orTwoRequiredValidate = new OrTwoRequiredValidate( 
etNick, etPassword); 
//密碼驗證 
Validate notPassword = new Validate(etPassword); 
NotEmptyValidator not2Empty = new NotEmptyValidator(this); 
notPassword.addValidator(not2Empty); 
//城市不能為空 
Validate etCity2 = new Validate(etCity); 
NotEmptyValidator etCity1 = new NotEmptyValidator(this); 
etCity2.addValidator(etCity1); 
//手機號不能為空 
Validate etMotto1 = new Validate(etMotto);

etMotto1.addValidator(phonevalidator); 
// 郵件驗證 
Validate emailValidate = new Validate(etEmail); 
EmailValidator emailValidator = new EmailValidator(this); 
emailValidator.setDomainName("qq\\.com");// 設置郵件規則:只能是QQ郵箱 
emailValidate.addValidator(emailValidator); 
// 重復密碼確認 
// ConfirmValidate confirmValidate = new ConfirmValidate(et_password1, 
// et_password2); 
// 網址 
/*Validate urlValidate = new Validate(et_url); 
UrlValidator urlValidator = new UrlValidator(this); 
urlValidate.addValidator(urlValidator);*/ 
// 4. Form表單addValidates這個Validate類即可 
form.addValidates(notPassword); 
form.addValidates(notEmptyValidate); 
form.addValidates(orTwoRequiredValidate); 
form.addValidates(emailValidate); 
form.addValidates(etCity2); 
form.addValidates(etMotto1); 
//form.addValidates(confirmValidate); 
// form.addValidates(urlValidate); 
} 
private void setListener() { 
bt_ok.setOnClickListener(new OnClickListener() { 
public void onClick(View v) { 
// 5. 最後調用form.validate()驗證即可，返回true表示驗證通過。 
boolean flag = form.validate(); 
if(flag){ 
Toast.makeText(MainActivity.this, "驗證成功！", Toast.LENGTH_LONG).show(); 
}else{ 
Toast.makeText(MainActivity.this, "驗證失敗", Toast.LENGTH_LONG).show();

另外還需導入一個類庫Android-Validator-master
