Android 短信验证码控件

Android 短信验证码控件,便于项目中使用统一样式,统一提示改动。个人觉得挺好用的

<span style="font-size:18px;">public class SMSButton extends Button {
/** 是否展示 */
private boolean mAttached;
/** 发送验证码后等待的时间 */
private int delayTime = 60;
/** Button 上面的文本 */
private String showText = "获取";
/** Button 等待的时候显示的文本 */
private String delayText = FORMATETAG + "秒";
/** 如今是否在倒计时 */
private boolean isDelayed = false; private SMSOnClickListener clickListener; private int currentDelayTime = 0; private static final String FORMATETAG = "%d"; private Runnable mTimer = new Runnable() { @Override
public void run() {
currentDelayTime -= 1;
if (currentDelayTime <= 0) {
isDelayed = false;
setClickable(true);
setText(showText);
} else {
getHandler().postDelayed(mTimer, 1000);
setDelayTimeText(currentDelayTime);
}
}
}; private void setDelayTimeText(int time) {
setText(String.format(delayText, time));
} public SMSButton(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
initView();
} public SMSButton(Context context, AttributeSet attrs) {
super(context, attrs);
initView();
} public SMSButton(Context context) {
super(context);
initView();
} @Override
public void setOnClickListener(OnClickListener l) {
super.setOnClickListener(new OnClickListener() { @Override
public void onClick(View v) {
if (!isDelayed) {// 假设没有在等待
if (clickListener != null) {
if (clickListener.validate()) {
setClickable(false);
isDelayed = true;
currentDelayTime = delayTime;
getHandler().post(mTimer);
clickListener.onClick();
}
}
}
}
});
} /**
* 初始化页面
*/
private void initView() {
String text = getText().toString().toString().trim();
if (text != null && !"".equals(text)) {
showText = text;
}
} @Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
if (!mAttached) {
mAttached = true;
setText(showText);
}
} @Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
if (mAttached) {
mAttached = false;
isDelayed = false;
getHandler().removeCallbacks(mTimer);
}
} public int getDelayTime() {
return delayTime;
} public void setDelayTime(int delayTime) {
this.delayTime = delayTime;
} public String getShowText() {
return showText;
} public void setShowText(String showText) {
this.showText = showText;
} public String getDelayText() {
return delayText;
} public void setDelayText(String start, String end) {
this.delayText = start + FORMATETAG + end;
} public SMSOnClickListener getSMSOnClickListener() {
return clickListener;
} public void setSMSOnClickListener(SMSOnClickListener clickListener) {
setOnClickListener(null);
this.clickListener = clickListener;
} public interface SMSOnClickListener {
public boolean validate(); public void onClick();
}</span>

使用方法:

	/**
* 样例
*
* smsButton = (SMSButton) findViewById(R.id.smsButton);
* smsButton.setShowText("获取");
* smsButton.setDelayText("等", "秒"); smsButton.setSMSOnClickListener(new
* SMSOnClickListener() {
*
* @Override public boolean validate() { return true; }
* @Override public void onClick() {
* ToastUtil.getInstance().toastInCenter(LoadingActivity.this,
* "onClick"); } });
*/
