• 最近在研究埋點統計，經過認真調研，整理出了我們自己的一套埋點方案，採用統計所有view點選事件的方案。由於網上內容有很多錯誤或不完整，本文將所有相關技術分析和程式碼完整的貼出來方便大家直接用，可以繞開好多彎路。

  本文解決一大問題是在有Fragment切換的時候，Fragment中的view與上一個Fragment中的view出現了衝突的問題，即在viewPage中會預先載入好下一個Fragment，造成點選事件統計衝突。view.isShown()用於判斷fragment是否為當前展示的那一個。

BaseActivity中程式碼

//統計埋點
    LinkedHashSet<View> views = new
 
 LinkedHashSet<View>();    
    public LinkedHashSet<View> allView = new LinkedHashSet<View>();
    int statusBarHeight;
    private String mClassName = this.getClass().getSimpleName();
//分發點選事件
    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            View view = getCurrentFocus();
            if
 
 (isHideInput(view, ev)) {
                HideSoftInput(view.getWindowToken());
            }
        }else if(ev.getAction() == MotionEvent.ACTION_UP){
            /*獲取當前點選位置，遍歷佈局，獲取當前點選位置對應的view，根據view對映路徑，與json檔案中的對比*/
            eventInViewCollect( ev);
        }
        return super.dispatchTouchEvent(ev);
    }

    @Override
 

    public void onWindowFocusChanged (boolean hasFocus){
        super.onWindowFocusChanged(hasFocus);

        if(!hasFocus) return;   //失去焦點時 不執行
        collectView();//收集統計用點選view的資訊
    }

    public void eventInViewCollect(MotionEvent event) {
        if (!HengChangAgent.isCollectMode())   return;  //非收集模式  退出

        double x = event.getRawX();
        double y = event.getRawY() - statusBarHeight;
        List touchViewid = new ArrayList<String> ();

        for(View view :allView) {
            Rect outRect = new Rect();
            view.getGlobalVisibleRect(outRect);
            if(outRect.contains((int)x ,(int)y )){
                String idName = ViewUtils.getResourceName(this,view.getId());
                // view.isShown()  view在上層才獲取其id   針對多個fragment切換情況
                if(!TextUtils.isEmpty(idName) && view.isShown()){
                    touchViewid.add(idName);
                }

                if (touchViewid.size()>0){
                    LogUtils.d("HengChangAgent" , "這是我們的埋點:"+touchViewid.toString());
                     String json= "";
                    try {
                        JSONObject jsonObj = new JSONObject();//物件，json形式
                        jsonObj.put("idName", touchViewid.toString());//向物件裡面新增值
                        json = jsonObj.toString();
                    }
                    catch (Exception e)
                    {
                        LogUtils.d("out" , "埋點json生成失敗");
                    }
                    HengChangAgent.requestBuriedPointStatistics(/*AppAccount.getInstance().getUserid()+*/"",json);
                }
            }
        }
    }

    /**
     * 收集統計用點選view的資訊
     */
    public void collectView() {
        if (!HengChangAgent.isCollectMode())   return;  //非收集模式  退出

        ViewGroup rootView = ViewUtils.getRootFrame(this);
        allView = getView(rootView);   //獲取到
        //過濾掉沒有定義過id的view
        LinkedHashSet<View> tempView = new LinkedHashSet<View>();
        for (View view :allView){
            String idName = ViewUtils.getResourceName(this,view.getId());
            if(!TextUtils.isEmpty(idName)){
                tempView.add(view);
            }
        }
        allView = tempView;

        LogUtils.d("out" , allView.size()+"");
        Rect outRect = new Rect();
        this.getWindow().getDecorView().getWindowVisibleDisplayFrame(outRect);
        statusBarHeight = outRect.top;
    }

     /*獲取所有View和沒有子View的ViewGroup*/
    public  LinkedHashSet<View> getView(ViewGroup viewGroup){
        if(viewGroup == null) return null;
        int count = viewGroup.getChildCount();
        for(int i=0;i<count;i++){
            View view = viewGroup.getChildAt(i);
            if(!(view instanceof ViewGroup)){
                    views.add(viewGroup);
                    views.add(view);
             }else if(view instanceof ViewGroup){
                getView((ViewGroup)view);
            }else{
                break;
            }
        }
        return views;
    }

BaseFragment中的onActivityCreated()新增如下程式碼

  /**
     * 收集統計用點選view的資訊
     */
    public void collectView() {
        if (!HengChangAgent.isCollectMode())   return;//非收集模式  退出

        if (getActivity() instanceof BaseActivity ){
            ViewGroup rootView =  ViewUtils.getRootFrame(getActivity());//獲取根viewGroup
            LinkedHashSet<View> views = ((BaseActivity)getActivity()).getView(rootView);
            if (views ==null || views.size()==0 ) return;

            //過濾掉沒有定義過id的view
            LinkedHashSet<View> filterViews = new LinkedHashSet<View>();
            for (View view :views){
                String idName = ViewUtils.getResourceName(getActivity(),view.getId());
                if(!TextUtils.isEmpty(idName) && idName.contains(":id/")){
                    filterViews.add(view);
                }
            }
            ((BaseActivity)getActivity()).allView.addAll(filterViews);
        }
    }
