要實現WindowManager添加的窗口，實現動畫顯示，就需要添加如下紅色的屬性，其他的添加View只要設置其Animations屬性也會實現動畫，當然自己實現也可，但是能直接用系統的已經實現好的，也很方便。
windowManager = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);
WindowParams = new LayoutParams(LayoutParams.FLAG_FULLSCREEN,LayoutParams.FLAG_FULLSCREEN); WindowParams.type=LayoutParams.TYPE_SYSTEM_ERROR; WindowParams.flags=LayoutParams.FLAG_ALT_FOCUSABLE_IM; //window gets focus WindowParams.format=PixelFormat.TRANSPARENT; //set the opacity to 100% WindowParams.windowAnimations=android.R.style.Animation_Translucent; // set the animation for the window WindowParams.gravity = Gravity.RIGHT | Gravity.TOP; windowManager.addView(view, WindowParams);
