WindowManager with Animation (is it possible?)

Question

Is there any way to inflate a view with WindowManager using Animation (at android's project)? I just can't do it even using the examples in sites! I used many examples but none worked!

public BannerLayout(Activity activity, final Context context) {
    super(context);

    this.context = 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); 

    wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);    

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    this.popupLayout = (RelativeLayout) inflater.inflate(R.layout.popup_activity, null);
    this.popupLayout.setVisibility(GONE);
    this.setActive(false);

    wm.addView(this.popupLayout, params);

    context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}


private void show(){
    Animation in = AnimationUtils.loadAnimation(this.context, android.R.anim.fade_in);
    this.popupLayout.setAnimation(in);

    this.setActive(true);
    this.popupLayout.setVisibility(VISIBLE);
}

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 real ViewGroup 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);
    }
}

sandrstar... worked perfectly! however... I wonder if it's possible using animation translation with these components. I need to make an effect up and down the screen with this component... — LeandroPortnoy, Jul 22 '13 at 12:09
private void show(){ //Animation fadeIn = (Animation) AnimationUtils.loadAnimation(getContext(), android.R.anim.fade_in); //this.startAnimation(fadeIn); //this.bannerRelativeLayout.setVisibility(VISIBLE); this.setActive(true); mPopupLayout.setVisibility(VISIBLE); final Animation in = new TranslateAnimation(0, 0, -1000, 0 ); in.setDuration(700); AnimationSet animation = new AnimationSet(false); animation.addAnimation(in); mPopupLayout.startAnimation(animation); } — LeandroPortnoy, Jul 22 '13 at 12:28
Sorry for delay. I've tried it and seems it works fine. May be You need to use params.width = ViewGroup.LayoutParams.MATCH_PARENT; params.height = ViewGroup.LayoutParams.MATCH_PARENT; for FrameLayout. — sandrstar, Jul 23 '13 at 02:45
@sandrstar Could you take a look at this question about WindowManager? Thank you http://stackoverflow.com/questions/27937250/viewpager-on-a-view-added-by-windowmanager-getting-java-lang-illegalargumentexc/27937559 — Hoa Vu, Jan 15 '15 at 02:09
@Run as far as I remember, it might be about background behavour — sandrstar, May 24 '21 at 13:11

Yes it is indeed possible. As long as the view you want to animate is inside a container, by container I mean for instance a LinearLayout or any other layout will do. Conclusively the view to be animated should not be the root view of a window and so you should be able to animate the view :) Hope it helps

I want to add something when you want to add an animation to WindowManager via :

params.windowAnimations = android.R.style.Animation_Translucent;

the animation style must be a system resource, it can not be an application

A style resource defining the animations to use for this window. This must be a system resource; it can not be an application resource because the window manager does not have access to applications. Android Developers DOCUMENTATION
