使用saripaar对android输入控件进行快速验证

saripaar是个android的第三方快速校验，使用注解快速添加验证规则。

public class LoginActivity extends Activity  implements

ValidationListener

@Required(order = 1, message="用户名不能为空")

    private EditText tbxUser=null;

@Required(order = 2,message="密码不能为空")

    private EditText tbxPsw =null;        private Validator validator;        @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.login);        if (android.os.Build.VERSION.SDK_INT > 9) {            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();            StrictMode.setThreadPolicy(policy);        }        //初始化监听        initListener();        //实例化校验类库

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

    }    /**     * 初始化监听     */    private void initListener() {                Button btn = (Button)this.findViewById(R.id.btnLogin);        tbxUser=(EditText)this.findViewById(R.id.txtUser);        tbxPsw=(EditText)this.findViewById(R.id.txtPassword);                btn.setOnClickListener(new OnClickListener(){            public void onClick(View v){                validator.validate();            }        });    }    private void login() {                 Dialog.showAlert(“Logining”, this );             };    @Override    public boolean onCreateOptionsMenu(Menu menu) {        // Inflate the menu; this adds items to the action bar if it is present.        getMenuInflater().inflate(R.menu.main, menu);        return true;    }    @Override    public void preValidation() {        // TODO Auto-generated method stub            }    @Override    public void onSuccess() {        // TODO Auto-generated method stub

    }    @Override    public void onFailure(View failedView, Rule<?> failedRule) {        // TODO Auto-generated method stub

String message = failedRule.getFailureMessage(); if (failedView instanceof EditText) { failedView.requestFocus(); ((EditText) failedView).setError(message); } else { Dialog.showToast(message,this); }

    }    @Override    public void onValidationCancelled() {        // TODO Auto-generated method stub            }}
