Android揭示动画启动活动

5

如何在两个活动之间使用Reveal Animation？有很多关于如何在Activity内启动视图的信息和示例，但我想单击按钮并启动Reveal Animation以打开下一个Activity。我尝试将第二个布局包含在第一个布局中并将其设置为不可见，然后在单击按钮时显示它。但是它不能正常工作。我想知道是否可以简单地将Reveal动画定义为XML，但我不知道如何做。

你可以为你的活动父布局添加动画效果。这是一个可能会帮助你的答案。它淡入了活动，但如果你理解了如何实现，你可以应用任何动画效果。 Android启动活动淡入要取消标准内置的活动动画效果，你可以使用这个 Intent.FLAG ：

intent.setFlag(Intent.FLAG_ACTIVITY_NO_ANIMATION);

当您启动您的Activity时。

Reveal Effect 对于活动和片段都能成功地运行。

应用以下代码以在活动或片段上设置 Reveal Effect。取消下面代码中特定动画的注释以使用它们。

-> 在 setcontentview 之后应用此代码。

                rootview = (RelativeLayout) findViewById(R.id.rootview);
                rootview.setBackgroundColor(getResources().getColor(R.color.colorAccent));
                rootview.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
                @Override
                public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                    v.removeOnLayoutChangeListener(this);

              /*//BOTTOM RIGHT TO TOP LEFT ANIMATION
                int cx = (framelayout.getLeft() + framelayout.getRight());
                int cy = (framelayout.getTop() + framelayout.getBottom());
                // get the hypothenuse so the radius is from one corner to the other
                int radius = (int) Math.hypot(right, bottom);
                Animator reveal = ViewAnimationUtils.createCircularReveal(v, cx, cy, 0, radius);
                reveal.setInterpolator(new AccelerateDecelerateInterpolator());
                reveal.setDuration(600);
                reveal.start();*/

              /*  //LEFT TOP TO BOTTOM RIGHT ANIMATION
                int cx1 = 0;
                int cy1 = 0;
                // get the hypothenuse so the radius is from one corner to the other
                int radius1 = (int) Math.hypot(right, bottom);
                Animator reveal1 = ViewAnimationUtils.createCircularReveal(v, cx1, cy1, 0, radius1);
                reveal1.setInterpolator(new DecelerateInterpolator(2f));
                reveal1.setDuration(1000);
                reveal1.start();*/

               /* //EFFECT START WITH CENTER
                float finalRadius = (float) Math.hypot(v.getWidth(), v.getHeight());
                int cx1 = (framelayout.getLeft() + framelayout.getRight()) / 2;
                int cy1 = (framelayout.getTop() + framelayout.getBottom()) / 2;
                Animator anim = ViewAnimationUtils.createCircularReveal(v, cx1, cy1, 0, finalRadius);
                anim.setDuration(1000);
                anim.setInterpolator(new AccelerateDecelerateInterpolator());
                anim.start();*/

                    //OPEN WITH BOTTOM CENTER
                    int cx = (rootview.getLeft() + rootview.getRight()) / 2;
                    int cy = (rootview.getTop() + rootview.getBottom());

                    reveal.setInterpolator(new AccelerateDecelerateInterpolator());
                    reveal.setDuration(350);
                    reveal.addListener(new Animator.AnimatorListener() {
                        @Override
                        public void onAnimationStart(Animator animation) {

                        }

            // get the initial radius for the clipping circle
            float initialRadius = (float) Math.hypot(cx, cy);

            // create the animation (the final radius is zero)
            Animator anim =
                    ViewAnimationUtils.createCircularReveal(myView, cx, cy, initialRadius, 0);
            anim.setDuration(50);
