窗口管理器，使用动画（这可能吗？） [英] WindowManager with Animation (is it possible?)

问题描述

有没有什么办法可以使用​​充气动画窗口管理视图（在android的项目）？我不能做到这一点，即使使用网站的例子！我用了很多例子，但没有工作！

 公共BannerLayout（活动活动，最终的上下文语境）{
    超（上下文）;

    this.context =背景;

    最后WindowManager.LayoutParams PARAMS =新WindowManager.LayoutParams（
            WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY，
            WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN |
            WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH，
            PixelFormat.TRANSLUCENT）;

    WM =（窗口管理器）context.getSystemService（Context.WINDOW_SERVICE）;

    LayoutInflater充气=（LayoutInflater）context.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
    this.popupLayout =（RelativeLayout的）inflater.inflate（R.layout.popup_activity，NULL）;
    this.popupLayout.setVisibility（GONE）;
    this.setActive（假）;

    wm.addView（this.popupLayout，则params）;

    context.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
}


私人无效秀（）{
    动画= AnimationUtils.loadAnimation（this.context，android.R.anim.fade_in）;
    this.popupLayout.setAnimation（在）;

    this.setActive（真正的）;
    this.popupLayout.setVisibility（可见）;
}
 

解决方案

我不知道有关你的任务的具体要求，但有两种方法提供动画窗口：

1. 使用 WindowManager.LayoutParams.windowAnimations 这样的：

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

2. 添加产生额外的容器观点，因为窗口管理器不是一个真正的的ViewGroup 等正常动画添加意见是不工作的。 这个问题已经被问已经，但它缺乏code。我会运用它通过以下方式：

    公共类BannerLayout扩展视图{
   
       私人最终语境mContext;
   
       私人最终的ViewGroup mPopupLayout;
   
       私人最终的ViewGroup mParentView;
   
       公共BannerLayout（活动活动，最终的上下文语境）{
           超（上下文）;
   
           mContext =背景;
   
           最后WindowManager.LayoutParams PARAMS =新WindowManager.LayoutParams（
                   WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY，
                   WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN |
                           WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH，
                   PixelFormat.TRANSLUCENT）;
   
           最后的窗口管理mWinManager =（窗口管理器）context.getSystemService（Context.WINDOW_SERVICE）;
   
           LayoutInflater充气=（LayoutInflater）context.getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
           mPopupLayout =（RelativeLayout的）inflater.inflate（R.layout.popup_activity，NULL）;
           mPopupLayout.setVisibility（GONE）;
   
           params.width = ActionBar.LayoutParams.WRAP_CONTENT;
           params.height = ActionBar.LayoutParams.WRAP_CONTENT;
   
           //默认变异
           // params.windowAnimations = android.R.style.Animation_Translucent;
   
           mParentView =新的FrameLayout（mContext）;
   
           mWinManager.addView（mParentView，则params）;
   
           mParentView.addView（mPopupLayout）;
           mPopupLayout.setVisibility（GONE）;
       }
   
       / **
        *显示视图
        * /
       公共无效展（）{
           在= AnimationUtils.loadAnimation（this.mContext，android.R.anim.fade_in）最终动画;
   
           in.setDuration（2000）;
   
           mPopupLayout.setVisibility（可见）;
           mPopupLayout.startAnimation（在）;
       }
   
       / **
        *隐藏查看
        * /
       公共无效隐藏（）{
           mPopupLayout.setVisibility（GONE）;
       }
   }
    

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);
}

解决方案

I'm not sure about exact requirements for Your task, but there's two ways to provide animation to window:

1. Use WindowManager.LayoutParams.windowAnimations like the following:

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

2. 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);
       }
   }
