I'm not sure about exact requirements for Your task, but there's two ways to provide animation to window:
Use
WindowManager.LayoutParams.windowAnimations
like the following:params.windowAnimations = android.R.style.Animation_Translucent;
Add additonal 'container' view, because
WindowManager
is not a realViewGroup
and so normal animation for adding views is not working with it. This question has been asked already, however it lacks the code. I would apply it the following way:public class BannerLayout extends View { private final Context mContext; private final ViewGroup mPopupLayout; private final ViewGroup mParentView; public BannerLayout(Activity activity, final Context context) { super(context); mContext = context; final WindowManager.LayoutParams params = new WindowManager.LayoutParams( WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY, WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, PixelFormat.TRANSLUCENT); final WindowManager mWinManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); mPopupLayout = (RelativeLayout) inflater.inflate(R.layout.popup_activity, null); mPopupLayout.setVisibility(GONE); params.width = ActionBar.LayoutParams.WRAP_CONTENT; params.height = ActionBar.LayoutParams.WRAP_CONTENT; // Default variant // params.windowAnimations = android.R.style.Animation_Translucent; mParentView = new FrameLayout(mContext); mWinManager.addView(mParentView, params); mParentView.addView(mPopupLayout); mPopupLayout.setVisibility(GONE); } /** * Shows view */ public void show(){ final Animation in = AnimationUtils.loadAnimation(this.mContext, android.R.anim.fade_in); in.setDuration(2000); mPopupLayout.setVisibility(VISIBLE); mPopupLayout.startAnimation(in); } /** * Hides view */ public void hide() { mPopupLayout.setVisibility(GONE); } }
