Android PopupWindow动画无法正常工作 [英] Android PopupWindow Animation not working

问题描述

我正在从屏幕的左上角单击按钮时显示PopupWindow.但是问题是，当我打开它时，它显示的非常快，这意味着没有动画发生，但是当我关闭它时，它的工作正常，这意味着它随着动画消失了.

I am showing PopupWindow on button click from top-left corner of the screen. But the problem is, when I am opening it, it will shown very fast, that means no animation occurs, but when I am closing it, its working fine, that means it is disappearing with animation.

这是我的代码，请帮助我.

Here is my code, please help me.

主类代码:

    LayoutInflater layoutInflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View layout = layoutInflater.inflate(R.layout.eosos_maptype_popup, null);
            final TextView txtContacts = (TextView) layout.findViewById(R.id.txtContacts);
            final TextView txtFeatured = (TextView) layout.findViewById(R.id.txtFeatured);
           final PopupWindow popup = new PopupWindow(CalendarView.this);

            popup.setAnimationStyle(R.style.animation);


            popup.setContentView(layout);
            popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
            popup.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
            popup.setFocusable(true);
            popup.setBackgroundDrawable(new BitmapDrawable(getResources()));

            // popup.showAtLocation(layout, Gravity.LEFT | Gravity.TOP, rect.left -
            // v.getWidth(), getDeviceHeight() - rect.top);
            popup.showAtLocation(layout, Gravity.TOP | Gravity.LEFT, rect.left, rect.bottom);

我的style.xml

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">

    <style name="animation" parent="android:Animation">
        <item name="@android:windowEnterAnimation">@anim/popup_show</item>
        <item name="@android:windowExitAnimation">@anim/popup_hide</item>
    </style>

</resources>

我的popup_show.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

    <translate android:fromXDelta="-100%" android:toXDelta="0" android:duration="1000"/>
</set>

我的popup_hide.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="0" android:toXDelta="-100%" android:duration="1000"/>
android:duration="200"/> -->
</set>

推荐答案

我在我的主要活动主题中使用了这个标签.

I was having this tag in my main Activity Theme.

<item name="android:windowDisablePreview">true</item>

我将其删除后-PopupWindow的输入"动画开始正常运行.

As soon as I removed it - "in" animation for PopupWindow started to work smooth.
