高仿淘宝送货地址暴走漫画系列(附demo)

演讲: 我是个程序员，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，開始要饭，我认为可怜。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…

谁说咱们程序员不能写出既幽默又能懂的博客呢,本人想推出一系列博文,能够给刚接触Android开发的做一个參考,也能够与接触Android已久的各路大神比較一下,本人喜欢交流,假设有写得不好的地方,欢迎大家指出.假设有更好的效果或者功能,希望大家多多指点,互相学习能够共同进步.

说了这么多,如今进入今天的猪蹄,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非常熟悉,在淘宝的Androidclient里面,有一个功能是设置收货地址,不清楚的同学能够自己下载个淘宝client,自己加入一下看看.

本人一向喜欢贴图,这样有图有真相,才干说服每一个人,废话不多说先上自己程序启动画面,然后执行界面,最后一张是淘宝client对比图.

淘宝client无法录屏所以这里仅仅能上静态的,大家能够自己打开淘宝client看看.

以下进行具体的代码解说:

(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,因为放在txt里面,读取操作非常不方便,所以我把它放到数据库,在后面的地区筛选非常快就出来,这个比淘宝还快哦,不信你们能够试一下.

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，同一时候，当任务运行完后，IntentService会自己主动停止，而不须要我们去手动控制。

简单的说IntentService类似于一条后台线程,但操作完毕时,我们不用手动去关闭Serveice,他会自己主动关闭.MyIntentService继承IntentService,之后必须实现一个无參数的构造方法MyIntentService(),然后还要重写onHandleIntent(Intent
intent);此后全部的后台操作就可以在onHandleIntent(Intent intent)运行;

public class MyIntentService extends IntentService {

	//必须实现的
	public MyIntentService() {
		super("MyIntentService");
		// TODO Auto-generated constructor stub
	}

	@Override
	protected void onHandleIntent(Intent arg0) {
		// TODO Auto-generated method stub
		//详细的操作
	}

}

 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,假设你进入地址筛选界面,看到数据不全或者报错,是由于数据还没有写完.

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開始时要做的事情,构造方法TimeCount()中的两个參数中,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.比如要倒计时30秒,每秒中间间隔时间是1秒,两个參数能够这样写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);
		}

		@Override
		public void onFinish() {  //倒计时运行结束时操作
			next = 0;
		}

		@Override
		public void onTick(long millisUntilFinished) {  //倒计运行时操作
		}
	}

(三)剩下的主要是一些界面的切换跟数据的读取,仅仅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() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int position,
					long arg3) {
				// TODO Auto-generated method stub
				mLinearLayout1.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() {

			@Override
			public void onItemClick(AdapterView<?

> arg0, View arg1, int position,
					long arg3) {
				// TODO Auto-generated method stub

				qu.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/其它...");
				 }
			}
		});

		mListView3.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> arg0, View arg1, int position,
					long arg3) {
				// TODO Auto-generated method stub

				String 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(),这样控件就能够获得焦点.

OnFocusChangeListener focusChanger = new OnFocusChangeListener() {

		@Override
		public void onFocusChange(View v, boolean hasFocus) {
			// TODO Auto-generated method stub
			myAddress.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() {

		@Override
		public void onClick(View v) {
			// TODO Auto-generated method stub
			switch (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.setFocusableInTouchMode(true);

				jiequText.requestFocus();
				break;

				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(), "改动收货地址成功", Toast.LENGTH_LONG).show();
					}else{
						Toast.makeText(getBaseContext(), "改动收货地址失败", 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(), "加入收货地址成功", Toast.LENGTH_LONG).show();
					}else{
						Toast.makeText(getBaseContext(), "加入收货地址失败", Toast.LENGTH_LONG).show();
					}
				}

					Intent intent = new Intent(BuyAddress.this, PersonAddress.class);
					startActivity(intent);
					finish();

				break;

			case R.id.download_layout1:

				break;
			default:

			}
		}
	};
