以编程方式添加动画效果为（以编程方式添加）popupWindow在安卓 [英] Programmatically adding animation effect to a (programmatically added) popupWindow in android

问题描述

所以，我有一个编程方式添加PopupWindow它看起来是这样的：

So, I have a programmatically added PopupWindow which looks like this:

        dialog = new PopupWindow(context);
        dialog.setContentView(ll);
        dialog.showAtLocation(view, Gravity.LEFT | Gravity.TOP, -70, 0);
        dialog.setWidth(w);
        dialog.setHeight(h - 50);
        dialog.setOutsideTouchable(true);
        //The dialog.update is somewhere else, I didn't bother adding it too as it is not important for this matter (I guess)

我想要做的是有某种动画效果，像它弹出从一按钮，我preSS这样的弹出窗口。 （这只是一个例子，我只是想任何形式的动画）。

What I want to do is to have some sort of animation effect , like it pops right from the button I press so the popup appears. (this is just an example, I just want any sort of animation).

文件将确定过，只要它不是基于XML（我发现那些已经 - 不是真的帮助我）。

Documentation would be ok too, as long as it is not XML based (I found those already -not really helping me).

如果还需要其他细节，我会发表评论或编辑的问题。

If other details are needed ,I will comment or edit the question.

推荐答案

所以，我设法解决这个问题。

So, I managed to deal with this problem.

有三个简单的步骤来实现的动画效果。

There are three simple steps to achieve the animation effect.

第一：     做两个XMLS属于animation.In这里下了我的情况是这两个。   animation_on.xml

First: Make two XMLs that are the animation.In my case were those two following down here. animation_on.xml

 <scale xmlns:android="http://schemas.android.com/apk/res/android"
  android:toXScale="1.0"              
  android:fromXScale="0.0"            

  android:toYScale="1.0"
  android:fromYScale="0.0"

  android:pivotX="0%"
  android:pivotY="50%"


  android:startOffset="100"
  android:duration="300" />

animation_off.xml

animation_off.xml

   <scale xmlns:android="http://schemas.android.com/apk/res/android"
   android:toXScale="0.0"              
   android:fromXScale="1.0"            

   android:toYScale="0.0"
   android:fromYScale="1.0"

   android:pivotX="0%"
   android:pivotY="50%"


   android:startOffset="100"
   android:duration="300" />

二：

<style name="animationName" parent="android:Animation">
    <item name="android:windowEnterAnimation">@anim/animation_on</item>
    <item name="android:windowExitAnimation">@anim/animation_off</item>
</style>

三：

 dialog = new PopupWindow(context);
 // ....other code, whatever you want to do with your popupWindow (named dialog in our case here)
 dialog.setAnimationStyle(R.style.animationName);
