动态增加删除控件，并记住里面的内容

 

 

1.用来保存对象

 

	private List<View> listOfPhoneSubView;//存放子View对象
	
	private List<Button> listOfPhoneButton;//左边的按钮，用来选择类型，文本的获取也是通过这里
	
	private List<EditText> listOfPhoneEditText;//右边的文本框，用来获取电话号码
	
	private List<String> listOfPhoneString;//用来保存左边按钮被点击的时候需要传递到别的Activity并显示的字符
	
	private List<Object> listOfPhoneTag;//用来标记对象


	private static List<HashMap<String, String>> listOfResolvedPhone;//存放从系统中解析出来的电话信息


        private int tagFlag = 0;

 

2.初始化

private void initList()//初始化ArrayList
{
		
	listOfPhoneSubView = new ArrayList<View>();
		
	listOfPhoneButton = new ArrayList<Button>();
		
	listOfPhoneEditText = new ArrayList<EditText>();
		
	listOfPhoneString = new ArrayList<String>();
				
	listOfPhoneTag = new ArrayList<Object>();
}

	private final String string1 = "住宅";//这个不要这样做，可以去读取系统的
	private final String string2 = "手机";
	private final String string3 = "单位";
	private final String string4 = "单位传真";
	private final String string5 = "住宅传真";
	private final String string6 = "寻呼机";
	private final String string7 = "其他";
	private final String string8 = "回拨号码";
	private final String string9 = "车载电话";
	private final String string10 = "公司总机";
	private final String string11 = "ISDN";
	private final String string12 = "总机";
	private final String string13 = "其他传真";
	private final String string14 = "无线装置";
	private final String string15 = "电报";
	private final String string16 = "TTY TDD";
	private final String string17 = "单位手机";
	private final String string18 = "单位寻呼机";
	private final String string19 = "助理";
	private final String string20 = "彩信";
	private final String string21 = "自定义";


public void initStringListOfNumber()//初始化listOfPhoneString
	{
		listOfPhoneString.add(string1);
		listOfPhoneString.add(string2);
		listOfPhoneString.add(string3);
		listOfPhoneString.add(string4);
		listOfPhoneString.add(string5);
		listOfPhoneString.add(string6);
		listOfPhoneString.add(string7);
		listOfPhoneString.add(string8);
		listOfPhoneString.add(string9);
		listOfPhoneString.add(string10);
		listOfPhoneString.add(string11);
		listOfPhoneString.add(string12);
		listOfPhoneString.add(string13);
		listOfPhoneString.add(string14);
		listOfPhoneString.add(string15);
		listOfPhoneString.add(string16);
		listOfPhoneString.add(string17);
		listOfPhoneString.add(string18);
		listOfPhoneString.add(string19);
		listOfPhoneString.add(string20);
		listOfPhoneString.add(string21);
	}

 

3.开启线程到系统中获取数据

Runnable r = new Runnable()
{
  	
	//处理数据
	public void run()
	{
		listOfResolvedPhone = QueryLinkmanInfoByRawContactId.queryPhoneInfo(EditLinkman.this, rawContactId);
			
                Message msg = new Message();
	        myHandler.sendMessage(msg);//得到电话信息以后通知更新界面
	}
};

  在queryPhoneInfo()中，我们调用并查询了系统的信息，并对系统中的数据进行匹配处理，最终返回回来得到listOfResolvedPhone会是List<HashMap<String, String>>保存的用户的信息，比如：PHONE_TYPE_ID:1

PHONE_TYPE:住宅 PHONE_NUMBER:13023895363

 

4.更新界面

private Handler myHandler = new Handler()
{
		
	@Override
	public void handleMessage(Message msg)
	{

          	showPhone();//根据listOfResolvedPhone中的值初始化显示电话信息的LinearLayout->llPhone
        }
};


public void showPhone()
{
		//让顶部啊按钮监听事件
	btnPhone.setOnClickListener(new OnClickListener() {
			
		public void onClick(View v) {
				// 增加一个子View
				System.out.println("增加一个Phone子View");
				addSubViewOfPhone();
			}
		});
		
		if(listOfResolvedPhone.isEmpty())
		{
			System.out.println("PhoneList is empty");
			//do nothing...
		}
		else
		{
			System.out.println("PhoneList is NO empty");
			int sizeOfResolvedPhone = listOfResolvedPhone.size();
			for(int i = 0; i < sizeOfResolvedPhone; i++)
			{
				
//				String phoneTypeId = listOfResolvedPhone.get(i).get(LD_PHONE_ID);//这样做虽然比较好，但是逻辑太乱了，暂时不考虑
				String phoneType = listOfResolvedPhone.get(i).get(LD_PHONE_TYPE);
				String phoneNumber = listOfResolvedPhone.get(i).get(LD_PHONE);
				
				LayoutInflater inflater = (LayoutInflater)getSystemService(LAYOUT_INFLATER_SERVICE);
				View subView = inflater.inflate(R.layout.sub_view_of_add_linkman, null);
								
				Button btnChooseType = (Button)subView.findViewById(R.id.svoal_btn_choose_type);
				EditText rlEditText = (EditText)subView.findViewById(R.id.svoal_et_input);
				rlEditText.setInputType(InputType.TYPE_CLASS_NUMBER);//设置输入类型和键盘为数字
				RelativeLayout rlDel = (RelativeLayout)subView.findViewById(R.id.svoal_rl_del);
				System.out.println("phoneType:" + phoneType);
				System.out.println("phoneNumber:" + phoneNumber);
				btnChooseType.setText(phoneType);
				rlEditText.setText(phoneNumber);
				
				btnChooseType.setOnClickListener(new BtnChooseNumberTypeClickedListener());
				
				rlDel.setOnClickListener(new RlNumberDelClickedListener());
				
				subView.setTag(tagFlag);
			    btnChooseType.setTag(tagFlag);
			    rlEditText.setTag(tagFlag);
			    rlDel.setTag(tagFlag);
			    
			    listOfPhoneSubView.add(subView);
			    listOfPhoneButton.add(btnChooseType);
			    listOfPhoneEditText.add(rlEditText);
				
			    listOfPhoneTag.add(rlDel.getTag());
				
			    tagFlag ++;
				
			    llPhone.addView(subView, LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);//增加一个View
			}
		}
		
	}

 

tag的作用是什么呢？

为什么要给每一个控件都加上一个Tag呢？

有两个方面：

1.当用户删除某一个元素的时候，不一定是从哪里删除，有可能是从列表中间删除，所以当用户点击子View上面的删除按钮的时候，需要通过v.getTag()获得要被删除的是哪个元素。通过这个Tag就可以将他们都删除了。

2.当点击选择电话类型的时候，同样，你需要把用户选择的哪个类型的字符串返回回来，你如何锁定是哪个Button需要被更改呢？同样也是通过Tag,我们在打开选择类型的Activity的时候，不仅将让用户进行选择的List传递过去，也将Tag传递过去，传递过去以后什么都不做，直接返回，返回回来以后就可以找到是哪个Button上面的类型名需要更改了。
