引语: 我是个程序猿，一天我坐在路边一边喝水一边苦苦检查bug。 这时一个乞丐在我边上坐下了，开始要饭，我觉得可怜，就给了他1块钱。 然后接着调试程序。他可能生意不好，就无聊的看看我在干什么，然后过了一会，他缓缓地指着我的屏幕说，这里少了个分号…

谁说咱们程序猿不能写出既幽默又能懂的博客呢,本人想推出一系列博文,可以给刚接触Android开发的做一个参考,也可以与接触Android已久的各路大神比较一下,本人喜欢交流,如果有写得不好的地方,欢迎大家指出.如果有更好的效果或者功能,希望大家多多指点,互相学习可以共同进步.

说了这么多,现在进入今天的猪蹄,推出<<暴走漫画系列--高仿淘宝收货地址>>,有网购经验的同学应该对这个很熟悉,在淘宝的Android客户端里面,有一个功能是设置收货地址,不清楚的同学可以自己下载个淘宝客户端,自己添加一下看看.

本人一向喜欢贴图,这样有图有真相,才能说服每个人,废话不多说先上自己程序启动画面,然后运行界面,最后一张是淘宝客户端对照图.

淘宝客户端无法录屏所以这里只能上静态的,大家可以自己打开淘宝客户端看看.

下面进行详细的代码讲解:

(一)本人在程序启动的时候开了一条后台服务landDivideServeice,目的是为了将全国的省市县总共4,189条数据插入到手机数据库里面去,原本的数据是保存在7个txt里面的,由于放在txt里面,读取操作很不方便,所以我把它放到数据库,在后面的地区筛选很快就出来,这个比淘宝还快哦,不信你们可以试一下.

这里要注意的一点是landDivideServeice是继承IntentService的,不是直接继承Service的.

IntentService是继承于Service并处理异步请求的一个类，在IntentService内有一个工作线程来处理耗时操作，启动IntentService的方式和启动传统Service一样，同时，当任务执行完后，IntentService会自动停止，而不需要我们去手动控制。

简单的说IntentService类似于一条后台线程,但操作完成时,我们不用手动去关闭Serveice,他会自动关闭.MyIntentService继承IntentService,之后必须实现一个无参数的构造方法MyIntentService(),然后还要重写onHandleIntent(Intent intent);此后所有的后台操作即可在onHandleIntent(Intent intent)执行;

public class MyIntentService extends IntentService {//必须实现的public MyIntentService() {super("MyIntentService");// TODO Auto-generated constructor stub}@Overrideprotected void onHandleIntent(Intent arg0) {// TODO Auto-generated method stub//具体的操作}}

 so ga...

(二)在程序启动的第一个activity里,我弄了一条倒计时线程,时间总共是20秒,目的是想为数据写入数据库争取多一些时间,如果你进入地址筛选界面,看到数据不全或者报错,是因为数据还没有写完.

实现倒计时功能主要是继承CountDownTimer类,重写onTick和onFinsh这两个方法,onFinish()中的代码是计时器结束的时候要做的事情;onTick(Long m)中的代码是你倒计时开始时要做的事情,构造方法TimeCount()中的两个参数中,前者是倒计的时间数,后者是倒计每秒中间 的间隔时间，都是以毫秒为单位.例如要倒计时30秒,每秒中间间隔时间是1秒,两个参数可以这样写TimeCount(20000,1000).

TimeCount time = new TimeCount(20000, 1000);
time.start();

/* 定义一个倒计时的内部类 */class TimeCount extends CountDownTimer {public TimeCount(long millisInFuture, long countDownInterval) {super(millisInFuture, countDownInterval);}@Overridepublic void onFinish() {  //倒计时执行结束时操作next = 0;}@Overridepublic void onTick(long millisUntilFinished) {  //倒计执行时操作}}

(三)剩下的主要是一些界面的切换跟数据的读取,只要思路正确是不会被搞混的.

landDivideDB = LandDivideDB.getInstance(getBaseContext());List<LandDivide> landDivide = landDivideDB.queryAddress("superior=?", new String[]{"1"});Iterator<LandDivide> iterator = null;if(landDivide!=null){iterator = landDivide.iterator();while(iterator.hasNext()){LandDivide l = iterator.next();sheng.add(l.getName());}}else{return;}

mListView1.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) {// TODO Auto-generated method stubmLinearLayout1.setVisibility(View.GONE);mLinearLayout2.setVisibility(View.VISIBLE);mLinearLayout3.setVisibility(View.GONE);shi.clear();String name = sheng.get(position);String code = null;shengStr = name;shengTxt2.setText(name);List<LandDivide> landDivide = landDivideDB.queryAddress("name=?", new String[]{name});Iterator<LandDivide> iterator= landDivide.iterator();while(iterator.hasNext()){LandDivide l = iterator.next();code = l.getCode();break;}List<LandDivide> landDivide_2 = landDivideDB.queryAddress("superior=?", new String[]{code});Iterator<LandDivide> iterator_2= landDivide_2.iterator();while(iterator_2.hasNext()){LandDivide l = iterator_2.next();shi.add(l.getName());}shiAdapter.notifyDataSetChanged();quAdapter.clear();quAdapter.notifyDataSetChanged();}});mListView2.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) {// TODO Auto-generated method stubqu.clear();String name = shi.get(position);String code = null;shiStr = name;shengTxt3.setText(shengStr);shiTxt3.setText(name);List<LandDivide> landDivide = landDivideDB.queryAddress("name=?", new String[]{name});Iterator<LandDivide> iterator= landDivide.iterator();while(iterator.hasNext()){LandDivide l = iterator.next();code = l.getCode();break;}List<LandDivide> landDivide_2 = landDivideDB.queryAddress("superior=?", new String[]{code});if(landDivide_2!=null){Iterator<LandDivide> iterator_2= landDivide_2.iterator();while(iterator_2.hasNext()){LandDivide l = iterator_2.next();qu.add(l.getName());}}quAdapter.notifyDataSetChanged();if(qu.size()<1){mLinearLayout1.setVisibility(View.GONE);mLinearLayout2.setVisibility(View.VISIBLE);mLinearLayout3.setVisibility(View.GONE);Intent i = new Intent(AddressChoose.this,BuyAddress.class);i.putExtra("address", shengStr+","+shiStr);startActivity(i);finish();}else{mLinearLayout1.setVisibility(View.GONE);mLinearLayout2.setVisibility(View.GONE);mLinearLayout3.setVisibility(View.VISIBLE);mListView3.setVisibility(View.VISIBLE);topView3.setText("请选择  县区/其他...");}}});mListView3.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> arg0, View arg1, int position,long arg3) {// TODO Auto-generated method stubString name = qu.get(position);quStr = name;Intent i2 = new Intent(AddressChoose.this,BuyAddress.class);i2.putExtra("address", shengStr+" "+shiStr+" "+quStr);startActivity(i2);finish();}});

(四)这个是选择好地址之后的界面,主要还是界面的转换跟焦点的获取

有时候setFocusable(true)跟setFocusableInTouchMode(true)并不能使控件获得焦点,要再之前加上一句requestFocus(),这样控件就可以获得焦点.

OnFocusChangeListener focusChanger = new OnFocusChangeListener() {@Overridepublic void onFocusChange(View v, boolean hasFocus) {// TODO Auto-generated method stubmyAddress.setStreet(jiequText.getText().toString());myAddress.setName(nameText.getText().toString());myAddress.setPhone(phoneText.getText().toString());switch (v.getId()) {case R.id.my_set_buyaddress_jiequ:if (!hasFocus && myAddress.getStreet().length() > 0) {jiequText.setVisibility(View.GONE);jiequLinear.setVisibility(View.VISIBLE);jiequTextView.setText(myAddress.getStreet());}if (hasFocus) {jiequText.setSelectAllOnFocus(true);}break;case R.id.my_set_buyaddress_name:if (!hasFocus && myAddress.getName().length() > 0) {nameText.setVisibility(View.GONE);nameLinear.setVisibility(View.VISIBLE);nameTextView.setText(myAddress.getName());}if (hasFocus) {nameText.setSelectAllOnFocus(true);}break;case R.id.my_set_buyaddress_phone:if (!hasFocus && myAddress.getPhone().length() > 0) {phoneText.setVisibility(View.GONE);phoneLinear.setVisibility(View.VISIBLE);phoneTextView.setText(myAddress.getPhone());}if (hasFocus) {phoneText.setSelectAllOnFocus(true);}break;default:break;}}};OnClickListener click = new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch (v.getId()) {case R.id.my_set_buyaddress_sheng_linear:Intent i = new Intent(BuyAddress.this, AddressChoose.class);i.putExtra("Boolean", "aaa");startActivity(i);break;case R.id.my_set_buyaddress_jiequ_linear:jiequText.setVisibility(View.VISIBLE);jiequLinear.setVisibility(View.GONE);jiequText.setFocusable(true);jiequText.setFocusableInTouchMode(true);jiequText.requestFocus();break;case R.id.my_set_buyaddress_name_linear:nameText.setVisibility(View.VISIBLE);nameLinear.setVisibility(View.GONE);nameText.setFocusable(true);nameText.setFocusableInTouchMode(true);nameText.requestFocus();break;case R.id.my_set_buyaddress_phone_linear:phoneText.setVisibility(View.VISIBLE);phoneLinear.setVisibility(View.GONE);phoneText.setFocusable(true);phoneText.setFocusableInTouchMode(true);phoneText.requestFocus();break;case R.id.my_set_buyaddress_address_btn:myAddress.setStreet(jiequText.getText().toString());myAddress.setName(nameText.getText().toString());myAddress.setPhone(phoneText.getText().toString());if (myAddress.getPhone().length() > 0) {phoneText.setVisibility(View.GONE);phoneLinear.setVisibility(View.VISIBLE);phoneTextView.setText(myAddress.getPhone());}postBtn.requestFocus();postBtn.setFocusable(true);postBtn.setFocusableInTouchMode(true);if (myAddress.getProvinces().length() < 1 || myAddress.getStreet().length() < 1|| myAddress.getName().length() < 1 || myAddress.getPhone().length() < 1) {Toast.makeText(getBaseContext(), "请完整填写收货人资料", 0).show();return;}myAddress.setStatus(checkBox.isChecked());AddressDB addressDB = AddressDB.getInstance(getBaseContext());if(checkBox.isChecked()){List<AddressInfo> list = addressDB.queryAddress();if(list!=null){Iterator<AddressInfo> iterator = list.iterator();while(iterator.hasNext()){AddressInfo a = iterator.next();a.setStatus(false);addressDB.updeteAddress(a);}}}if (addressinfo != null) {if(addressDB.updeteAddress(myAddress)){Toast.makeText(getBaseContext(), "修改收货地址成功", Toast.LENGTH_LONG).show();}else{Toast.makeText(getBaseContext(), "修改收货地址失败", Toast.LENGTH_LONG).show();}} else {SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");Date date = new Date();String id = format.format(date);myAddress.setId(id);if(addressDB.insertAddress(myAddress)){Toast.makeText(getBaseContext(), "添加收货地址成功", Toast.LENGTH_LONG).show();}else{Toast.makeText(getBaseContext(), "添加收货地址失败", Toast.LENGTH_LONG).show();}}Intent intent = new Intent(BuyAddress.this, PersonAddress.class);startActivity(intent);finish();break;case R.id.download_layout1:finish();break;default:break;}}};
