popupwindow进入和退出动画

1.在res/anim文件下创建pophidden_anim和popshow_anim

pophidden_anim代码如下：

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate        android:duration="1000"        android:fromYDelta="100%"        android:toYDelta="0" />    <alpha        android:duration="1000"        android:fromAlpha="1.0"        android:toAlpha="0.0" /></set>

</pre><pre name="code" class="html">popshow_anim代码如下

<pre name="code" class="html"><?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <translate        android:duration="1000"        android:fromYDelta="0"        android:toYDelta="100%" />    <alpha        android:duration="1000"        android:fromAlpha="0.0"        android:toAlpha="1.0" /></set>

2.res/values/styles添加如下代码

    <style name="popwindow_anim_style" parent="android:Animation" mce_bogus="1">        <item name="android:windowEnterAnimation">@anim/popshow_anim</item>        <item name="android:windowExitAnimation">@anim/pophidden_anim</item>    </style>

3.java代码

<span style="white-space:pre"></span>View convertview=View.inflate(getActivity(),R.layout.pop_setting,null);        popupWindow = new PopupWindow(convertview,ViewGroup.LayoutParams.MATCH_PARENT,-2,true);        popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));        popupWindow.setOutsideTouchable(true);        popupWindow.showAtLocation(view, Gravity.BOTTOM,0,0);        popupWindow.setAnimationStyle(R.style.popwindow_anim_style);

<span style="white-space:pre"></span>//一定要添加update()        popupWindow.update();        backgroundAlpha(0.8f);        popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {            @Override            public void onDismiss() {                backgroundAlpha(1f);            }        });

    /**     * 设置透明度     * @param bgAlpha     */    public void backgroundAlpha(float bgAlpha) {        WindowManager.LayoutParams lp = getActivity().getWindow().getAttributes();        lp.alpha = bgAlpha; //0.0-1.0        getActivity().getWindow().setAttributes(lp);    }
