ObjectAnimator animator1 = ObjectAnimator.ofFloat(viewBG, "alpha", 1, 0); //X轴平移旋转 animator1.setStartDelay(470); animator1.setDuration(300); animator1.setInterpolator(new SmoothInterpolator()); animator1.start(); animator1.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {@Override public void onAnimationUpdate(ValueAnimator animation) { float currentValue = https://www.it610.com/article/(float) animation.getAnimatedValue(); if (currentValue> 0.002f) { viewBG.setAlpha(currentValue); } else {//如果太小直接设成0就好了 viewBG.setAlpha(0); } } });
【ObjectAnimator animator1 = ObjectAnimator.ofFloat(viewBG, "alpha", 1, 0); 一些手机会出现的问题】
