注册处理的activity：
1：初始化布局文件
1 ImageView yangzheng_number_img; 2 EditText phone_number; 3 EditText user_name; 4 EditText user_pwd; 5 EditText yanzhengNumber; 6 Button reSend; 7 Button registerOk; 8 TextView back_login;
1 phone_number=(EditText) findViewById(R.id.phone_number); 2 phoneNumber=phone_number.getText().toString(); 3 4 yanzhengNumber=(EditText)findViewById(R.id.yanzheng_number); 5 yangzheng_number_img=(ImageView)findViewById(R.id.yanzheng_number_img); 6 7 user_name=(EditText) findViewById(R.id.user_name); 8 user_pwd=(EditText) findViewById(R.id.user_pwd); 9 10 11 registerOk=(Button) findViewById(R.id.register_ok); 12 registerOk.setOnClickListener(this); 13 reSend = (Button) findViewById(R.id.reSend); 14 reSend.setOnClickListener(this); 15 back_login=(TextView) findViewById(R.id.back_login); 16 back_login.setOnClickListener(this);
2：手机获取验证码
1 phoneNumber=phone_number.getText().toString(); 2 String smsContent ="您的验证码为:"+Code.getInstance().getCode()+",请尽快输入页面"; 3 SmsManager smsManager = SmsManager.getDefault(); 4 if(phoneNumber.equals("")){ 5 Toast.makeText(getApplicationContext(), "请输入手机号码", Toast.LENGTH_SHORT).show(); 6 }else{ 7 //判断号码是否重复 8 if(smsContent.length()>70){ 9 List<String> contents = smsManager.divideMessage(smsContent); 10 for(String c:contents){ 11 smsManager.sendTextMessage(phoneNumber, null, c, null, null); 12 } 13 }else{ 14 smsManager.sendTextMessage(phoneNumber, null, smsContent, null, null); 15 } 16 Toast.makeText(UserRegisterActivity.this, "短信发送成功", Toast.LENGTH_LONG); 17 reSend.setText("重新发送"); 18 }
