WindowManager with Animation (is it possible?)
提问by LeandroPortnoy
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!
有没有办法使用动画（在 android 的项目中）使用 WindowManager 来膨胀视图？即使使用站点中的示例，我也无法做到！我用了很多例子，但没有一个奏效！
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:
我不确定您的任务的确切要求，但有两种方法可以为窗口提供动画：
Use
WindowManager.LayoutParams.windowAnimationslike the following:params.windowAnimations = android.R.style.Animation_Translucent;Add additonal 'container' view, because
WindowManageris not a realViewGroupand 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); } }
使用
WindowManager.LayoutParams.windowAnimations如下：params.windowAnimations = android.R.style.Animation_Translucent;添加附加的“容器”视图，因为
WindowManager它不是真实的ViewGroup，因此用于添加视图的普通动画无法使用它。这个问题已经被问过了，但是它缺少代码。我会通过以下方式应用它：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); } }

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
是的，这确实是可能的。只要您想要动画的视图在容器内，容器我的意思是例如 LinearLayout 或任何其他布局都可以。最后，要动画的视图不应该是窗口的根视图，因此您应该能够动画视图:)希望它有所帮助
