如果扩展动画在API调用的成功块中不起作用,则它不起作用.但是,如果我把它从成功块中剔除,那么它就可以正常工作.

我必须在成功块内调用动画块.因为数据来自API.

这是示例.

getWeeklyWaterDate方法：

public voID getWeeklyWaterData(final WaterDataCallBack callBack){    // Find last monday    Calendar lastMonday = Calendar.getInstance();    while (lastMonday.get(Calendar.DAY_OF_WEEK) != Calendar.MONDAY)    {        lastMonday.add(Calendar.DATE, -1);    }    Calendar Now = Calendar.getInstance();    lastMonday.add(Calendar.DAY_OF_YEAR, -1);    lastMonday.set(Calendar.HOUR, 24);    lastMonday.set(Calendar.MINUTE, 0);    lastMonday.set(Calendar.SECOND, 0);    lastMonday.set(Calendar.MILliSECOND, 0);    HashMap<String, String> params = new HashMap<>();    params.put("startDate", Utils.formatYYMMDDDTHHMMSSz(lastMonday.getTimeInMillis()));    params.put("endDate", Utils.formatYYMMDDDTHHMMSSz(Now.getTimeInMillis()));    ServiceConnector.groupamaAPI.getMyWaters(params).enqueue(new SuccessCallback<MyWaterResponse>() {        @OverrIDe        public voID onSuccess(Response<MyWaterResponse> response) {            super.onSuccess(response);            callBack.onWaterDataReceived(response.body());        }    });}

从片段中调用getWeeklyWaterDataMethod.

WaterHelper.getCurrent().getWeeklyWaterData(new WaterHelper.WaterDataCallBack() {        @OverrIDe        public voID onWaterDataReceived(MyWaterResponse waterResponse) {            Collections.reverse(waterResponse.waterLogs);            for (Integer i = 0 ; i < waterResponse.waterLogs.size() ; i++)            {                WaterLog waterLog = waterResponse.waterLogs.get(i);                Calendar calendar = Calendar.getInstance();                calendar.setTime(waterLog.LogDate);                dates.add(calendar);                wateramounts.add(new Wateramount(calendar, waterLog.WaterMililiter.intValue()));            }            preparetotalAndAverage(waterResponse.wateraverage);            prepareGraph2();        }    });

这是动画代码：

final Integer finalGraphMaxY = 6000;            chartContainerLL.getVIEwTreeObserver().addOnGlobalLayoutListener(new VIEwTreeObserver.OnGlobalLayoutListener()            {         @OverrIDe                public voID onGlobalLayout()                {                    chartContainerLL.getVIEwTreeObserver().removeOnGlobalLayoutListener(this);                    // Animate bars                    Integer totalHeight = chartContainerLL.getHeight();                    ExpandHeightAnimation expandHeightAnimation = new ExpandHeightAnimation(barMonday, 55);                    expandHeightAnimation.setDuration(800/* animation time */);                    barMonday.startAnimation(expandHeightAnimation);                    ExpandHeightAnimation expandHeightAnimation2 = new ExpandHeightAnimation(barTuesday, 30);                    expandHeightAnimation2.setDuration(800/* animation time */);                    barTuesday.startAnimation(expandHeightAnimation2);                    ExpandHeightAnimation expandHeightAnimation3 = new ExpandHeightAnimation(barWednesday, 40);                    expandHeightAnimation3.setDuration(800/* animation time */);                    barWednesday.startAnimation(expandHeightAnimation3);                    ExpandHeightAnimation expandHeightAnimation4 = new ExpandHeightAnimation(barThursday, 30);                    expandHeightAnimation4.setDuration(800/* animation time */);                    barThursday.startAnimation(expandHeightAnimation4);                    ExpandHeightAnimation expandHeightAnimation5 = new ExpandHeightAnimation(barFrIDay, 40);                    expandHeightAnimation5.setDuration(800/* animation time */);                    barFrIDay.startAnimation(expandHeightAnimation5);                    if(dates.size() >= 6 && dates.get(5).get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)                    {                        ExpandHeightAnimation expandHeightAnimation6 = new ExpandHeightAnimation(barSaturday, totalHeight * getNeededDayWateramount(Calendar.SATURDAY).mililiter / finalGraphMaxY);                        expandHeightAnimation6.setDuration(800/* animation time */);                        barSaturday.startAnimation(expandHeightAnimation6);                    }                    if(dates.size() >= 7 && dates.get(6).get(Calendar.DAY_OF_WEEK) == Calendar.SATURDAY)                    {                        ExpandHeightAnimation expandHeightAnimation7 = new ExpandHeightAnimation(barSunday, totalHeight * getNeededDayWateramount(Calendar.SUNDAY).mililiter / finalGraphMaxY);                        expandHeightAnimation7.setDuration(800/* animation time */);                        barSunday.startAnimation(expandHeightAnimation7);                    }                }            });

ExpandHeightAnimation类

public class ExpandHeightAnimation extends Animation{    int targetHeight;    VIEw vIEw;    public ExpandHeightAnimation(VIEw vIEw, int targetHeight) {        this.vIEw = vIEw;        this.targetHeight = targetHeight;    }    @OverrIDe    protected voID applytransformation(float interpolatedTime, transformation t) {        vIEw.getLayoutParams().height = (int) (targetHeight * interpolatedTime);        vIEw.requestLayout();    }    @OverrIDe    public voID initialize(int wIDth, int height, int parentWIDth,            int parentHeight) {        super.initialize(wIDth, height, parentWIDth, parentHeight);    }    @OverrIDe    public boolean willChangeBounds() {        return true;    }}

解决方法:

调用onCreate()或onCreateVIEw()时,需要添加GlobalLayoutListener.

首先添加两个动画标志.如果两者都正确,则动画将开始.

boolean animateFlag1 = false;boolean animateFlag2 = false;

其次,在onCreate()中添加全局布局侦听器：

llContainer.getVIEwTreeObserver().addOnGlobalLayoutListener(new VIEwTreeObserver.OnGlobalLayoutListener()    {        @OverrIDe        public voID onGlobalLayout()        {            llContainer.getVIEwTreeObserver().removeOnGlobalLayoutListener(this);            animateFlag1 = true;            animate();        }    });

您可以看到,调用onGlobalLayout()时,删除侦听器,将first标志设置为true并调用animate方法.

在这些之后,对开始动画的回调执行相同的 *** 作.将您的第二个标志设置为true,

@OverrIDepublic voID success(Result result) {    animateFlag2 = true;    animate();}

这是动画方法,其中包括您之前编写的onGlobalLayout()方法代码.

private voID animate(){    if(animateFlag1 && animateFlag2){        // Animate bars        ExpandHeightAnimation expandHeightAnimation = new ExpandHeightAnimation(vIEw, 500);        expandHeightAnimation.setDuration(800/* animation time */);        vIEw.startAnimation(expandHeightAnimation);        //More your codes to animate        //Set your all flags to false to prevent animating again        animateFlag1 = animateFlag2 = false;    }}
