android开发学习——注册时发送激活码

来源:互联网 发布:appmakr软件使用教程 编辑:程序博客网 时间:2024/06/05 19:19

模仿一些网站在注册的时候要填写手机号码,然后点击获取激活码,将会产生一个激活码,用短信的方式发到注册者的手机,然后用户需要查看短信,将激活码填写在注册页面,有时间限制。若超时则需要重新发送。 

strings.xml,其代码如下:

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="hello">Hello World, SendregActivity!</string>    <string name="app_name">发送验证码</string>    <string name="title">注册</string>    <string name="links">我已阅读并接受:<a href="http://www.baidu.com">《百度用户协议》 </a>   </string></resources> 

color.xml,其代码如下:

<?xml version="1.0" encoding="UTF-8"?><resources>   <color name="skyblue">#87CEEB</color><!--天蓝色 --> </resources>

main.xml,其代码如下:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" ><TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow     android:gravity="center">    <TextView     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:textSize="20sp"    android:text="手机号注册"/>    </TableRow>    </TableLayout> <TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow     android:gravity="left">    <TextView     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="手机号:"/>    <EditText     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:hint="请输入手机号码..."    android:id="@+id/phone"        />    </TableRow>    </TableLayout>       <TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow>    <Button     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="免费获取短信激活码"    android:id="@+id/sendnumber"        />    </TableRow>    </TableLayout>    <TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow     android:gravity="left">    <TextView     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="手短信激活码:"/>    <EditText     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:hint="输入激活码..."    android:id="@+id/number"        />    <TextView          android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:id="@+id/counttime"        />    </TableRow>    </TableLayout>   <TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow     android:gravity="left">    <TextView     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="密码:"/>    <EditText     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:password="true"    android:hint="请输入密码..."    android:id="@+id/paw"        />    </TableRow>    </TableLayout>  <TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow     android:gravity="left">    <CheckBox    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:id="@+id/agree"     android:checked="true"/>    <TextView     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="@string/links"/>    </TableRow>    </TableLayout>   <TableLayout       android:layout_width="fill_parent"    android:layout_height="wrap_content"    >    <TableRow android:gravity="center">    <Button     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:textSize="30sp"    android:text="注册"    android:id="@+id/send"    android:background="@color/skyblue"        />    </TableRow>    </TableLayout></LinearLayout>


下面来看主Activity文件,其内容如下:下面来看Activity文件,其代码如下:

import java.util.logging.Logger;import java.util.regex.Matcher;import java.util.regex.Pattern;import android.app.Activity;import android.app.PendingIntent;import android.content.Intent;import android.os.Bundle;import android.os.CountDownTimer;import android.telephony.gsm.SmsManager;import android.telephony.gsm.SmsMessage;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.CheckBox;import android.widget.EditText;import android.widget.TextView;import android.widget.Toast;public class SendregActivity extends Activity {    /** Called when the activity is first created. */ Button sendnumber,send;EditText phone,pwd,number;String temp="";String phonenum="";CheckBox agree;TimeCount timeco;TextView timecount;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        sendnumber=(Button) findViewById(R.id.sendnumber);        send=(Button) findViewById(R.id.send);        phone=(EditText) findViewById(R.id.phone);        pwd=(EditText) findViewById(R.id.paw);        number=(EditText) findViewById(R.id.number);//激活码        agree=(CheckBox) findViewById(R.id.agree);        timecount=(TextView) findViewById(R.id.counttime);        timeco = new TimeCount(120000, 1000);//时间为120秒        sendnumber.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubfor(int i=0;i<5;i++){//产生一个五位数的激活码int k=(int) (Math.random()*10);temp+=k;}    phonenum=phone.getText().toString().trim();SmsManager smsmanger=SmsManager.getDefault();if(isPhoneNumberValid(phonenum)){PendingIntent mPI=PendingIntent.getBroadcast(SendregActivity.this, 0, new Intent(), 0);smsmanger.sendTextMessage(phonenum, null, "你的激活码是:"+temp, mPI, null);Toast.makeText(SendregActivity.this, "激活码发送成功!", Toast.LENGTH_LONG).show(); timeco.start();}else{Toast.makeText(SendregActivity.this, "电话格式不正确,请检查!", Toast.LENGTH_LONG).show();}    }});        send.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stub phonenum=phone.getText().toString().trim();if(!isPhoneNumberValid(phonenum)){Toast.makeText(SendregActivity.this, "电话格式不正确,请检查!", Toast.LENGTH_LONG).show();}else if(phonenum.length()==0){Toast.makeText(SendregActivity.this, "请输入电话号码!", Toast.LENGTH_LONG).show();}else if(number.getText().toString().trim().length()==0){Toast.makeText(SendregActivity.this, "请输入激活码!", Toast.LENGTH_LONG).show();}else if(!number.getText().toString().equals(temp)){Toast.makeText(SendregActivity.this, "激活码不正确!", Toast.LENGTH_LONG).show();}else if(pwd.getText().toString().trim().length()<6||pwd.getText().toString().trim().length()>12){Toast.makeText(SendregActivity.this, "密码不能少于6为多余12位!!", Toast.LENGTH_LONG).show();}else if(!agree.isChecked()){Toast.makeText(SendregActivity.this, "请先阅读百度协议!!", Toast.LENGTH_LONG).show();}else{Toast.makeText(SendregActivity.this, "注册成功!", Toast.LENGTH_LONG).show();timeco.cancel();}}});    }    /*检查字符串是否为电话号码的方法,并回传true or false的判断值*/    public static boolean isPhoneNumberValid(String mobiles){       Matcher m = null;    if(mobiles.trim().length()>0){        Pattern p = Pattern.compile("^((13[0-9])|(15[0-3])|(15[7-9])|(18[0,5-9]))\\d{8}$");             m= p.matcher(mobiles);         }    else{         return false;    }        return m.matches();         }     /* 定义一个倒计时的内部类 */    class TimeCount extends CountDownTimer {    public TimeCount(long millisInFuture, long countDownInterval) {    super(millisInFuture, countDownInterval);//参数依次为总时长,和计时的时间间隔    }    @Override    public void onFinish() {//计时完毕时触发   temp="";   Toast.makeText(SendregActivity.this, "超时,需要重新发送激活码!", Toast.LENGTH_LONG).show();    }    @Override    public void onTick(long millisUntilFinished){//计时过程显示       timecount.setText("倒计时:"+millisUntilFinished /1000+"秒");    }    }}


程序要调用SmsManager来发送短信,因此还需要授予改程序发送短信的权限,也就是在AndroidManifest.xml文件中增加如下代码:

 <uses-permission android:name="android.permission.SEND_SMS"/>
