基于mob短信验证的账号注册demo

////////////////////2016/05/14////////////////////////

/////////////////eclipse api 21/////////////////////

快期末考试了，把之前做的项目整理一下，分享点demo，基于mob短信验证的账号注册demo，那个mob的key的注册直接去mob官网注册就好了，不多说了，先看一下效果图。

首先在mob官网下载短信验证sdk，咱这有demo，一会贴出来，直接复制demo里的sdk就好了，

首先在res文件中新建raw文件夹，把libs文件复制进去，再把smssdk_errors.xml文件复制到values文件夹中，

复制这几个文件到lib文件夹下，好了，开始敲代码，首先去AndroidManifest.xml文件下注册权限，

素材等都在我的demo里了，需要的拿去。

短信验证我们用到了自动填充短信验证码，还有发送验证码后60秒短信倒计时；

我们需要写两个类

SmsContent.java 自动填充短信验证码

package com.xbw.login;

import java.util.ArrayList;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import android.app.Activity;
import android.database.ContentObserver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Handler;
import android.widget.EditText;

public class SmsContent extends ContentObserver {

	public static final String SMS_URI_INBOX = "content://sms/inbox";
	private Activity activity = null;
	private String smsContent = "";
	private EditText verifyText = null;

	public SmsContent(Activity activity, Handler handler, EditText verifyText) {
		super(handler);
		this.activity = activity;
		this.verifyText = verifyText;
	}

	@SuppressWarnings("deprecation")
	@Override
	public void onChange(boolean selfChange) {
		super.onChange(selfChange);
		Cursor cursor = null;// 光标
		// 读取收件箱中指定号码的短信
		cursor = activity.managedQuery(Uri.parse(SMS_URI_INBOX), new String[] {
				"_id", "address", "body", "read" }, "address=? and read=?",
				new String[] { "106571207117008", "0" }, "date desc");//mob短信验证号码
		if (cursor != null) {// 如果短信为未读模式
			cursor.moveToFirst();
			if (cursor.moveToFirst()) {
				String smsbody = cursor
						.getString(cursor.getColumnIndex("body"));
				System.out.println("smsbody=======================" + smsbody);
				String pattern = "[1-9]\\d*";
				Pattern p = Pattern.compile(pattern);
				Matcher m = p.matcher(smsbody.toString());
				ArrayList al =new ArrayList();
				while(m.find())
				{
					al.add(m.group(0));
				}
				if(!al.isEmpty())
				verifyText.setText(al.get(0).toString());
			}
		}
	}
}

TimeCountUtil.java倒计时

package com.xbw.login;

import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Color;
import android.os.CountDownTimer;
import android.text.Spannable;
import android.text.SpannableString;
import android.text.style.ForegroundColorSpan;
import android.widget.Button;

public class TimeCountUtil extends CountDownTimer {
	 private Activity mActivity;
	 private Button btn;//按钮

	// 在这个构造方法里需要传入三个参数，一个是Activity，一个是总的时间millisInFuture，一个是countDownInterval，然后就是你在哪个按钮上做这个是，就把这个按钮传过来就可以了
	 public TimeCountUtil( Activity mActivity,long millisInFuture, long countDownInterval,Button btn) {
	 super(millisInFuture, countDownInterval);
	 this.mActivity = mActivity;
	 this.btn =btn;
	 }


	 @SuppressLint("NewApi")
	 @Override
	 public void onTick(long millisUntilFinished) {
	 btn.setClickable(false);//设置不能点击
	 btn.setText(millisUntilFinished / 1000 + "秒后可重新发送");//设置倒计时时间

	//设置按钮为灰色，这时是不能点击的
	 btn.setBackground(mActivity.getResources().getDrawable(R.drawable.btn_long_white));
	 Spannable span = new SpannableString(btn.getText().toString());//获取按钮的文字
	 span.setSpan(new ForegroundColorSpan(Color.RED), 0, 2, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);//讲倒计时时间显示为红色
	 btn.setText(span);

	 }
	 @SuppressLint("NewApi")
	 @Override
	 public void onFinish() {
	 btn.setText("重新获取验证码");
	 btn.setClickable(true);//重新获得点击
	 btn.setBackground(mActivity.getResources().getDrawable(R.drawable.btn_long_red));//还原背景色

	 }


	 }
