近期項目比較忙，今日纔有時間給你們分享android的一些實用的知識~javascript

what is getLocationInWindow

android中一種獲取view座標的方法，獲取在當前窗口內的絕對座標。
int[] location = new int[2] ;
view.getLocationInWindow(location);
解釋：
location[0] -----> x座標
location[1] -----> y座標java

對比

android中獲取view座標的方法有兩種：android

getLocationInWindow
- 獲取在當前窗口內的絕對座標
getLocationOnScreen
- 獲取在整個屏幕內的絕對座標
- 從屏幕頂端算起，包括了通知欄的高度

踩過的坑

在onCreate裏面調用，會獲得location[0]和location[1]的值均爲空，這是由於UI控件還沒加載好的緣由。因此咱們能夠使用view.post(runnable)方法去獲取或者在onWindowFocusChanged(boolean hasFocus)方法中獲取。git

使用案例

案例效果圖以下：github

核心代碼分析

首先咱們須要保存頂部Tab滑動各item寬度座標，代碼以下：api

/** * 保存症狀詳情頂部tab橫向寬度座標 * @author leibing * @createTime 2016/10/19 * @lastModify 2016/10/19 * @param * @return */
    private void saveSymptomDetailHorizontalWidth() {
        int[] location = new int[2];
        for (int i = 0; i < symptomDetailContainerLy.getChildCount(); i++) {
            getSingleNavigation(i).getLocationInWindow(location);
            symptomDetailHorizontalWidth[i] = location[0];
        }
    }複製代碼

而後保存症狀詳情滑動高度座標，代碼以下：網絡

/** * 保存症狀詳情滑動高度座標 * @author leibing * @createTime 2016/10/19 * @lastModify 2016/10/19 * @param * @return */
    private void savesymtomDetailScvHeight() {
            // 症狀詳情
            final int[] symptomModuleLoc = new int[2];
            final int[] symptomLocation = new int[2];
            // 症狀模塊
            symptomModuleLy.post(new Runnable() {
                @Override
                public void run() {
                    symptomModuleLy.getLocationInWindow(symptomModuleLoc);
                    symtomDetailScvHeight[0] = 0;
                }
            });
            // 病因模塊
            pathogenyModuleLy.post(new Runnable() {
                @Override
                public void run() {
                    pathogenyModuleLy.getLocationInWindow(symptomLocation);
                    symtomDetailScvHeight[1] = symptomLocation[1] - symptomModuleLoc[1];
                }
            });
            // 檢查模塊
            checkoutModuleLy.post(new Runnable() {
                @Override
                public void run() {
                    checkoutModuleLy.getLocationInWindow(symptomLocation);
                    symtomDetailScvHeight[2] = symptomLocation[1] - symptomModuleLoc[1];
                }
            });
            // 診斷模塊
            diagnoseModuleLy.post(new Runnable() {
                @Override
                public void run() {
                    diagnoseModuleLy.getLocationInWindow(symptomLocation);
                    symtomDetailScvHeight[3] = symptomLocation[1] -symptomModuleLoc[1];
                }
            });
            // 預防模塊
            preventModuleLy.post(new Runnable() {
                @Override
                public void run() {
                    preventModuleLy.getLocationInWindow(symptomLocation);
                    symtomDetailScvHeight[4] = symptomLocation[1] - symptomModuleLoc[1];
                }
            });
            foodTreatModuleLy.post(new Runnable() {
                @Override
                public void run() {
                    // 食療模塊
                    foodTreatModuleLy.getLocationInWindow(symptomLocation);
                    symtomDetailScvHeight[5] = symptomLocation[1] - symptomModuleLoc[1];
                }
            });
    }複製代碼

接着設置滑動監聽、點擊頂部Tab事件，代碼以下：ide

/** * 症狀詳情頂部tab橫向監聽 * @author leibing * @createTime 2016/10/19 * @lastModify 2016/10/19 * @param * @return */
    class OnSymtomHorizontalScClickedListener implements View.OnClickListener {
        @Override
        public void onClick(View view) {
            isTopClick = true;
            setSymtomHorizontalCurrentPostion(view, true, 0, 0);
        }
    }

  @Override
    protected void registerListener() {
        // 退出當前頁面
        findViewById(R.id.iv_actionbar_back).setOnClickListener(this);
        // 設置滑動監聽
        if (symptomDetailScv != null)
            symptomDetailScv.setScrollViewListener(new ObservableScrollView.ScrollViewListener() {
                @Override
                public void onScrollChanged(ObservableScrollView scrollView, int x, int y, int oldx, int oldy, int oritention) {
                        if (isTopClick) {
                            isTopClick = false;
                            return;
                         }
                        // 症狀詳情
                        // 若是症狀詳情頂部tab橫向寬度座標或者症狀詳情滑動高度座標則返回
                        if (symtomDetailScvHeight == null || symptomDetailHorizontalWidth == null)
                            return;
                        if (y >= symtomDetailScvHeight[0] && y < symtomDetailScvHeight[1]) {
                            // 症狀
                            setSymtomHorizontalCurrentPostion(symptomDetailContainerLy.getChildAt(0),
                                    false, symptomDetailHorizontalWidth[0], y);
                        } else if (y >= symtomDetailScvHeight[1] && y < symtomDetailScvHeight[2]) {
                            // 病因
                            setSymtomHorizontalCurrentPostion(symptomDetailContainerLy.getChildAt(1),
                                    false, symptomDetailHorizontalWidth[1], y);
                        } else if (y >= symtomDetailScvHeight[2] && y < symtomDetailScvHeight[3]) {
                            // 檢查
                            setSymtomHorizontalCurrentPostion(symptomDetailContainerLy.getChildAt(2),
                                    false, symptomDetailHorizontalWidth[2], y);
                        } else if (y >= symtomDetailScvHeight[3] && y < symtomDetailScvHeight[4]) {
                            // 診斷
                            setSymtomHorizontalCurrentPostion(symptomDetailContainerLy.getChildAt(3),
                                    false, symptomDetailHorizontalWidth[3], y);
                        } else if (y >= symtomDetailScvHeight[4] && y < symtomDetailScvHeight[5]) {
                            // 預防
                            setSymtomHorizontalCurrentPostion(symptomDetailContainerLy.getChildAt(4),
                                    false, symptomDetailHorizontalWidth[4], y);
                        } else if (y >= symtomDetailScvHeight[5]) {
                            // 食療
                            setSymtomHorizontalCurrentPostion(symptomDetailContainerLy.getChildAt(5),
                                    false, symptomDetailHorizontalWidth[5], y);
                        }
                }
            });
    }複製代碼

最後設置頂部Tab位置，代碼以下：佈局

/** * 設置症狀詳情頂部tab位置 * @author leibing * @createTime 2016/10/19 * @lastModify 2016/10/19 * @param view * @param fromClick 是否點擊 * @param x x座標 * @param y y座標 * @return */
    public void setSymtomHorizontalCurrentPostion(View view, boolean fromClick, int x, int y){
        // 若是不是點擊事件並橫向滑動控件不爲空則滑動到指定座標
        if (!fromClick && symptomDetailHscv != null) {
            symptomDetailHscv.scrollTo(x, y);
        }
        if (view == null){
            return;
        }
        if (view.getTag() == null)
            return;
        // 獲取當前位置
        int position = (Integer) view.getTag();
        // 若是當前位置非上次位置
        if (lastPosition != position){
            // 若是頂部tab動態加載容器爲空，則從新實例化
            if (symptomDetailContainerLy == null) {
                // 頂部tab動態加載容器
                symptomDetailContainerLy = (LinearLayout) findViewById(R.id.ly_symptom_detail_container);
            }
            // 設置上次位置藍色下滑線不可見
            getNavigationImageView(lastPosition).setVisibility(View.INVISIBLE);
            // 設置上次位置字體顏色爲黑色
            getNavigationTextView(lastPosition).setTextColor(
                    getResources().getColor(R.color.text_color_black));
            // 設置當前位置藍色下劃線可見
            getNavigationImageView(position).setVisibility(View.VISIBLE);
            // 設置當前位置字體顏色爲藍色
            getNavigationTextView(position).setTextColor(
                    getResources().getColor(R.color.title_color));
        }
        lastPosition = position;
        if (symptomDetailScv != null && fromClick) {
            symptomDetailScv.scrollTo(0, symtomDetailScvHeight[position]);
        }
    }複製代碼
