android應用開發--------------看RadioGroup源碼，寫類似單選選項卡的集成控件（如底部導航，tab等等）

 

 

上面就是需求設計，4個類似的布局控件，每次只能選擇一個，然後得到上面對應的錢數。（上面只是效果圖，實際數據是從服務器獲取，然後付到控件上）

看到這種，我們就回想到，幾種實現方法。

1.把這個整體寫一個布局，在xml布局中，復制粘貼，代碼，湊夠4個。非常不建議這樣，因為4個的布局樣式是一樣的，只是數據可能不相同，所以我們應該寫一個組合控件然後重復利用。

2.就是寫一個單個的布局控件，然後設置一些設置數據的方法，然後重復利用它。引入四個控件。這樣在一定程度上達到了代碼重復利用性，但是以後在布局中這一塊要是去掉，可能你要修改的代碼也是會比較多了。

 

3.還有一種就是使用GridView，我們看多多個相同的布局，就會相到使用listView和GridView。這種方法是可以使用的，不過在有個問題是，如果沒有數據的前提下，它將會是一個空布局，不太好看，對於後期修改或去掉這一部分布局的話，相對來說好算比較好修改，去電一個GridView和他相對應的adapter就好了。

 

下面我們在針對第二種來說一下，解決一下他的不好修改的特點，因為，我們一般寫完程序之後就會懶得修改，所以我們在第一次編寫的時候，要為以後的修改做好准備，一切為了方便修改。因為程序員都知道，產品的需求是一直在變化，。。。。。你們懂就好，假如，產品想把這個東西換一個樣式，或是直接其用掉這一部分布局，那我們就盡量做到，刪除幾行代碼搞定它。那麼就需要我們在2方式的基礎上再封裝一層。

把四個弄成一個控件，然後再整體加進去。

 

你們仔細看，上面的是不是一個單選按鈕組?就和androd的radiobutton控件相似，然後用一個radioGroup包含。

所以我們可以針對這個寫一個類似RadioGroup和RadioButton那樣類似的東西。

 

首先先解決RadioButton類似的控件，先寫一個布局，這樣的布局。

 

布局為，

就這麼簡單寫一下。

然後把其整體封裝為一個組合控件，編寫方法什麼的。

 

public class RechargeValueLayout extends FrameLayout{

	private View view;
	private TextView mZengs;
	private TextView mMoney;
	private TextView mCords;
	private String money;
	private LinearLayout mllbg;

	private Boolean isChecked;
	
	public RechargeValueLayout(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		// TODO Auto-generated constructor stub
	}

	public RechargeValueLayout(Context context, AttributeSet attrs) {
		super(context, attrs);
		view = View.inflate(context, R.layout.recharge_value_item, this);
		mllbg = (LinearLayout)view.findViewById(R.id.llbg);
		mZengs = (TextView)view.findViewById(R.id.tvZengs);
		mMoney = (TextView)view.findViewById(R.id.tvMoney);
		mCords = (TextView)view.findViewById(R.id.tvcords);
	}

	public RechargeValueLayout(Context context) {
		super(context);
	}
	
	public void setChecked(Boolean isChecked){
		Log.i(TAG2, isSelected===>>>>+isChecked);
		if(isChecked==this.isChecked){
			return;
		}
		if(isChecked){
			mllbg.setBackgroundResource(R.drawable.btn_recharge_active);
		}else{
			mllbg.setBackgroundResource(R.drawable.btn_recharge);
		}
		this.isChecked = isChecked;
	}
	
	public boolean isChecked(){
		return this.isChecked;
	}
	
	public void setZengsValue(int value){
		if(value>0){
			mZengs.setVisibility(View.VISIBLE);
			mZengs.setText(送+value+);
		}else{
			mZengs.setVisibility(View.GONE);
		}
	}
	public String getMoneyValue(){
		return this.money;
	}
	public void setMoneyValue(int value){
		if(value>0){
			mMoney.setText(value+);
			this.money = value+;
		}else{
			mMoney.setText(0幣);
		}
	}
	
	public void setCordsValue(int value){
		if(value>0){
			mCords.setText(value+幣);
		}else{
			mCords.setText(0幣);
		}
	}
	
	
}

這樣，你就直接可以引用其路徑，直接使用這個組合控件。其實到這裡，就實現了2方式所說的。但是僅用這個，那麼我們只是實現了布局重用，但是不好進行替換修改，你可以想想，這麼一個控件裡有3個textView，並且我們要對其textView進行賦值，也就是說我們要對12TextView經行操作，如果這12TextView放在我們activity裡，一是代碼過於臃腫，二是你想想，如果以後去掉的話，我們就得對這所有涉及到這12個TextView的代碼都得進行刪除。

所以我們現在要把這四個控件再給他們一個類似RadioGroup的容器，在RadioGroup裡有一個點擊事件，只要對RadioCroup設置上監聽，那麼在RadioGroup的控件就自動設置上了監聽，所以，咱activity裡面我們只需要這個RadioGroup的控件代碼，1個對12個，你們想想到知道後續修改操作那種方便。

 

開始是想的定義的布局控件，這個布局控件得到自己裡面的孩子數，然後再遍歷循環給孩子設置上監聽，可是失敗了。

具體的說說失敗的代碼。

這是布局，首先把RechargeValueLayout放到RechargeValueGroup裡面，然後RechargeValueGroup裡面得到自己的孩子數，

public class RechargeValueGroup extends FrameLayout {

	private OnItemTabClickListener listener;
	
	public RechargeValueGroup(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
		// TODO Auto-generated constructor stub
	}

	public RechargeValueGroup(Context context, AttributeSet attrs) {
		super(context, attrs);
		init();
	}

	
	public RechargeValueGroup(Context context) {
		super(context);
		// TODO Auto-generated constructor stub
	}
	
	private void init() {
		int count = getChildCount();
		for (int i = 0; i < count; i++) {
			getChildAt(i).setOnClickListener(new OnClickListener() {
				
				@Override
				public void onClick(View v) {
					if(listener!=null){
						listener.onItemClick(RechargeValueGroup.this,v.getId());
					}
				}
			});
		}
	}

	/**
	 * 定義Group的監聽，點擊每一個子按鈕就會返回相對應子按鈕的信息，以方便操作
	 */
	public interface OnItemTabClickListener {
		public void onItemClick(RechargeValueGroup view, int checkedId);
	}
	
}

可是這樣有個問題，在構造函數執行的時候是獲得不到孩子數的，這樣就沒法給孩子設置上監聽了。

然後我就想記得以前是在onMeasure裡面可以得到孩子數，把init的部分放到onMeasure或onLayout方法裡，孩子數是得到了，可是這兩個方法是，只要布局有變化，其都會走一遍，也就是說只要你布局有變化，他們就會執行，所以出現了一些問題，所以在這兩個方法中設置監聽是不太好的。

那怎麼樣技能自動獲得孩子數，又能給對應的孩子設置上監聽呢？

 

於是我就去看了一下RadioGroup的源碼。

這就是RadioGroup的源碼，加上注釋什麼的一共400來行代碼，所以不是很多，然後就開始看源碼。其中一開始在init（）中，有這麼一個監聽，

mPassThroughListener = new PassThroughHierarchyChangeListener();
        super.setOnHierarchyChangeListener(mPassThroughListener);

然後找到其對應的監聽，

 private class PassThroughHierarchyChangeListener implements
            ViewGroup.OnHierarchyChangeListener {
        private ViewGroup.OnHierarchyChangeListener mOnHierarchyChangeListener;

        /**
         * {@inheritDoc}
         */
        public void onChildViewAdded(View parent, View child) {
            if (parent == RadioGroup.this && child instanceof RadioButton) {
                int id = child.getId();
                // generates an id if it's missing
                if (id == View.NO_ID) {
                    id = View.generateViewId();
                    child.setId(id);
                }
                ((RadioButton) child).setOnCheckedChangeWidgetListener(
                        mChildOnCheckedChangeListener);
            }

            if (mOnHierarchyChangeListener != null) {
                mOnHierarchyChangeListener.onChildViewAdded(parent, child);
            }
        }

        /**
         * {@inheritDoc}
         */
        public void onChildViewRemoved(View parent, View child) {
            if (parent == RadioGroup.this && child instanceof RadioButton) {
                ((RadioButton) child).setOnCheckedChangeWidgetListener(null);
            }

            if (mOnHierarchyChangeListener != null) {
                mOnHierarchyChangeListener.onChildViewRemoved(parent, child);
            }
        }
    }

這個監聽繼承了ViewGroup.OnHierarchyChangeListener接口，你通過查資料你就會發現，這個監聽接口是對其 層次結構的監聽，不像
onMeasure或onLayout，他只有在層次結構發生變化時，也就是說在添加view和移除view的時候才會調用，所以他有兩個回調方法。onChildViewAdded和onChildViewRemoved。在初始化的時候，子布局是一個一個的被添加到RadioGroup，所以調用onChildViewAdded，可以得帶其對應的孩子，就可以對其設置監聽了。

這樣設置就不會出現重復執行等問題。

 

然後這一步解決了就好說了。下一把就是我們觸發監聽後，要這幾個控件協調控制，因為只有一個是能被選中。所以在監聽的時候我們應該去改變子控件的狀態等。

這一步就不細說了，應該都會順著理清楚，就是只保持一個被選中就可以。附上代碼，就是根據需求稍微改動了一下RadioGroup

就上上面的代碼，由於我是使用的在Xml裡面添加子控件，所以就沒寫addView方法，有興趣的可以自己寫一下addview方法。

然後，我有加了一個public void setDataOfTabs(List datas)這個方法，就是把得到的數據直接付給這個控件，這樣，就會自動把所有子控件附上值。

這樣比較方便，因為數據是從服務器拿到的，使用Gson工具類，直接把數據封裝成了集合，只要把集合傳入就可實現自動賦值。非常方便，自己不需要一個一個的去賦值了。

 

根據RadioCroup修改的，只要根據不同的情況稍作修改就可以滿足很多情況，例如，我們常見的底部導航，tab選擇等等，只要我們稍把不同的item子控件改動一下，我們就會很快的實現一個單選樣式的按鈕組。

 

使用方法也很簡單，在代碼中

mRechargeGroup= (RechargeValueGroup) findViewById(R.id.rechargeGroup);
  mRechargeGroup.setOnItemTabClickListener(new OnItemTabClickListener() {

   @Override
   public void onItemClick(RechargeValueGroupview, int checkedId,String money) {
    // TODO Auto-generated method stub
    Log.i(TAG2, checkedId===>>>+checkedId);
    realPrice = money;
   }
   
  });

找到控件設置監聽，然後回掉回來各種參數，id等，我們也可以根據自己的需求去修改OnItemTabClickListener監聽接口中的onItemClick傳遞的參數來滿足自己的需求，

然後我們在適當的地方調用setDataOfTabs(List datas)這個方法來設置數據就好了。

xml裡面，就是上面的那段代碼

就這麼簡單，大家可以在這個基礎上來進行其他擴展什麼的。
