Android 在WindowManager上添加动画视图

我在WindowManager中添加了一个视图（customView）

WindowManager mWm = (WindowManager)activity.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);
WindowManager.LayoutParams(WindowManager.LayoutParams.FILL_PARENT, 0, PixelFormat.TRANSPARENT);
mWl.dimAmount = 0.0f;
mWm.addView(customView, mWl);

在自定义视图中，我将在按下“关闭”按钮时调用“平移”动画

////这是动画的处理程序////

final Handler translateHandler = new Handler();

final Runnable mtranslateUp = new Runnable() {
    public void run() {
        Log.v("TEST","mtranslateUp Runnable");
        startAnimation(translateUp);
    }
};

translateUp = new TranslateAnimation(0,0,0,-200);
translateUp.setFillAfter(true);
translateUp.setDuration(1000);
translateUp.setAnimationListener(new AnimationListener(){
        @Override
        public void onAnimationEnd(Animation animation) {
            Log.v("TEST","translateUp onAnimationEnd");
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }

        @Override
        public void onAnimationStart(Animation animation) {
            Log.v("TEST","translateUp onAnimationStart");
        }}
    );

////这是关闭按钮的侦听器////

View.OnClickListener closeButtonListener = new View.OnClickListener() {         

    public void onClick(View v) {
        translateHandler.post(mtranslateUp);
    }
};

////这是向上平移动画////

final Handler translateHandler = new Handler();

final Runnable mtranslateUp = new Runnable() {
    public void run() {
        Log.v("TEST","mtranslateUp Runnable");
        startAnimation(translateUp);
    }
};

translateUp = new TranslateAnimation(0,0,0,-200);
translateUp.setFillAfter(true);
translateUp.setDuration(1000);
translateUp.setAnimationListener(new AnimationListener(){
        @Override
        public void onAnimationEnd(Animation animation) {
            Log.v("TEST","translateUp onAnimationEnd");
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }

        @Override
        public void onAnimationStart(Animation animation) {
            Log.v("TEST","translateUp onAnimationStart");
        }}
    );

如果将customView添加到活动中，则这些代码可以正常工作

将customView添加到WindowManager时，onAnimationStart中的日志不会显示，但可以显示Runnable中的日志

有人能告诉我如何在添加到WindowManager的视图上制作动画吗？

我在连接到WindowManager的视图上遇到了类似的问题。请尝试将视图组添加到WindoManager，而不是直接添加视图。它应该可以工作。

windowManager需要安卓系统的动画。因此自定义动画将不起作用

您应该设置视图布局参数的动画。例如，我使用一种方法来更新视图布局：

    public void updateViewLayout(View view, Integer x, Integer y, Integer w, Integer h){
    if (view!=null) {
        WindowManager.LayoutParams lp = (WindowManager.LayoutParams) view.getLayoutParams();

        if(x != null)lp.x=x;
        if(y != null)lp.y=y;
        if(w != null && w>0)lp.width=w;
        if(h != null && h>0)lp.height=h;

        mWindowService.updateViewLayout(view, lp);
    }
}

显然，mWindowService是context.getSystemService（context.WINDOW\u服务）。 我在动画中触发此方法：

    public static void overlayAnimation(final View view2animate, int viewX, int endX) {
    ValueAnimator translateLeft = ValueAnimator.ofInt(viewX, endX);
    translateLeft.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator valueAnimator) {
            int val = (Integer) valueAnimator.getAnimatedValue();
            updateViewLayout(view2animate, val, null, null, null);

        }
    });
    translateLeft.setDuration(ANIMATION_DURATION);
    translateLeft.start();
}

我有个问题

当我在onAnimationUpdate中使用updateViewLayout并设置LayoutParams的宽度时，动画已删除帧

但是我设置了LayoutParams的x或y，动画就可以了

如以下代码所示：

        mViewWidth = 800;
        mViewHeight = 800;
        final int oldX = mFloatWindowParams.x;
        final int oldWidth = mFloatWindowParams.width;
        final int oldHeight = mFloatWindowParams.height;
        final int deltaWidth = mViewWidth - oldWidth;
        final int deltaHeight = mViewHeight - oldHeight;
        final boolean isWidthLarger = deltaWidth > deltaHeight;
        int first = isWidthLarger ? oldWidth : oldHeight;
        int end = isWidthLarger ? mViewWidth : mViewHeight;
        ValueAnimator va = ValueAnimator.ofInt(first, end);

        va.setDuration(1000);
        va.setInterpolator(new LinearInterpolator());
        va.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {

            public void onAnimationUpdate(ValueAnimator animation) {
                int value = (Integer) animation.getAnimatedValue();
                float fraction = animation.getAnimatedFraction();
                Log.i("onAnimationUpdate", value + "");
                if (isWidthLarger) {
                    mFloatWindowParams.width = value;
                    mFloatWindowParams.height = oldHeight + (int) (deltaHeight * fraction);
                } else {
                    mFloatWindowParams.width = oldWidth + (int) (deltaWidth * fraction);
                    mFloatWindowParams.height = value;
                }
                mFloatWindowParams.x = oldX - (int) (deltaWidth * fraction);

                mWindowManager.updateViewLayout(mRootView, mFloatWindowParams);
            }
        });
        va.start();

你有什么解决办法吗？请分享，我也面临着同样的问题。对我有用：）你的意思是将视图添加到视图组，然后将视图组添加到windowmanager？@alex你是如何解决的？我在

FrameLayout

中包含了一个

ImageView

，但是现在当我为

ImageView

设置动画时，它脱离了

FrameLayout

的边界，因此它不再可见。很酷，这是一种不将视图包装到视图组的正确方法。这是唯一对我有效的解决方案，谢谢！我试着用TranslateAnimation，但没有用骰子。
