popWindow

本文主要是介绍popWindow，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

 private void showPopWindow(View view) {long time = 1000;// 模糊动画  AlphaAnimation alphaAnimation = new AlphaAnimation(0, 1);alphaAnimation.setDuration(time);alphaAnimation.setFillAfter(true);// 缩放动画  ScaleAnimation scaleAnimation = new ScaleAnimation(0, 1, 0, 1, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);scaleAnimation.setDuration(time);scaleAnimation.setFillAfter(true);// 动画集合  AnimationSet animationSet = new AnimationSet(true);animationSet.addAnimation(scaleAnimation);animationSet.addAnimation(alphaAnimation);//下面是popWindow的部分// 找到布局文件View v = View.inflate(getContext(),R.layout.popup_window_app_mannager, null);PopupWindow popupWindow;popupWindow = new PopupWindow(v,LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT, true);popupWindow.setBackgroundDrawable(new ColorDrawable());popupWindow.showAsDropDown(view, 100, -view.getHeight());// 开始动画v.setAnimation(animationSet);}
