1、Android中完成“注冊應(yīng)用賬號模塊”的代碼清單范美英（北京信息職業(yè)技術(shù)學院）摘 要：Android中可以使用下拉列表、圖像按鈕、復選框完成較為復雜的UI，本文詳細羅列了“注冊應(yīng)用賬號模塊”的代碼清單。關(guān)鍵詞： Android；下拉列表；圖像按鈕；復選框 1 src/MainActivity.java類的代碼package com.book.testregister;import java.util.Iterator;import java.util.List;import java.util.Random;import android.app.Activity;import android

3、.Toast;public class MainActivity extends Activity implements OnItemSelectedListener Spinner spnCountry;EditText edtPhone;CheckBox chkAgreePolicy;/countryName用來記錄用戶所選的國家名稱/phone用來記錄用戶輸入的電話號碼/content用來拼接短信字符串String countryName=null,phone=null,content=null;Overrideprotected void onCreate(Bundle savedIn

4、stanceState) super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);spnCountry=(Spinner) this.findViewById(R.id.spn_country);edtPhone=(EditText) this.findViewById(R.id.edt_phone);chkAgreePolicy=(CheckBox) this.findViewById(R.id.chk_agreePolicy);/為下拉列表添加選擇監(jiān)聽spnCountry.setOnItemSele

5、ctedListener(this);public void clickReg(View v)/如果未勾選同意政策，則給用戶以操作提示，否則發(fā)送信息if(!chkAgreePolicy.isChecked()Toast.makeText(MainActivity.this, "請閱讀使用條款與隱私政策，并同意", Toast.LENGTH_LONG).show();else/捕獲電話號碼格式不正確的異常try/取得目標電話號碼，為發(fā)送短信做準備phone=edtPhone.getText().toString();/生成四位隨機數(shù)，做驗證碼Random r=new Rand

6、om();r.setSeed(System.currentTimeMillis();int verifyTemp=0;String verifyCode=""for(int i=0;i<4;i+)verifyTemp=r.nextInt(10);verifyCode += verifyTemp;content="Dear "+countryName+" friend, " +"your verified code is"+verifyCode+"nSent By BigApp"/發(fā)送短信S

7、msManager smsManager=SmsManager.getDefault();/分割短信/if(content.length()>70)/List<String> msgs=smsManager.divideMessage(content);/Iterator<String> iter=msgs.iterator();/while(iter.hasNext()/String msg=iter.next();/將msg發(fā)送到接收方/smsManager.sendTextMessage(phone, null, content, null, null);c

8、atch(Exception e)/ 在信息提示框中輸出異常描述Toast.makeText(MainActivity.this, String.valueOf(e), Toast.LENGTH_LONG).show();Overridepublic void onItemSelected(AdapterView<?> parent, View view, int position,long itemID) /當下拉列表框中某項被選中時，將該項的值寫到countryName字符串中countryName=parent.getItemAtPosition(position).toSt
