how to make animation for popup window in android

I think the problem is you have provided only one set of animation style. But actually a PopupWindow requires two animations. One will be used by it when window is shown and other one to hide the window.

This is how you should do it,

1) Create Two Different set of animations.

say, popup_show.xml and popup_hide.xml and add it to your anim folder which you have to create inside res folder.

2) Now inside values folder create a xml called styles.xml and add these animations to it like this,

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

3) Now set this style to your PopupWindow animation,

 popup.setAnimationStyle(R.style.Animation);

Now it automatically detects window enter and exit and provides with the required animation.

i am using a popup animation with this code:

// Creating the PopupWindow       layoutInflater = (LayoutInflater)     getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);       inflatedLayoutView = layoutInflater.inflate(R.layout.packages_popup,null);     inflatedLayoutView.setAnimation(AnimationUtils.loadAnimation(this, R.animator.popupanim)    popup_l = new PopupWindow(inflatedLayoutView);   popup_l.setWidth(FrameLayout.LayoutParams.WRAP_CONTENT);   popup_l.setHeight(FrameLayout.LayoutParams.WRAP_CONTENT);        popup_l.setFocusable(true);   // Clear the default translucent background   popup_l.setBackgroundDrawable(new BitmapDrawable());          popup_l.showAtLocation(parent, Gravity.CENTER, 0 , 0);      popup_l.setOutsideTouchable(false);

located in /res/animator/popupanim.xml(popupanim.xml) the animation code is:

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" ><alpha android:fromAlpha="0.0"        android:toAlpha="1.0"         android:interpolator="@android:anim/accelerate_interpolator"         android:duration="500"        android:repeatCount="0"/></set>

The PopupWindow custom layout is more convenient, and the display position is freedom there is not any restricted.Use Below code and enjoy animation.In this animation use bottom slide in and slide out but you can change only slide in/out animation and animate any where in your app and one thing more according to your animation, you must to change your Gravity ->> BOTTOM, TOP etc.

anim resource folder:

1.slide_in_bottom.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"     android:shareInterpolator="false"    >  <translate      android:duration="@integer/dialogplus_animation_default_duration"      android:fromXDelta="0%"      android:fromYDelta="100%"      android:toXDelta="0%"      android:toYDelta="0%"      /></set>

2.slide_out_bottom.xml:

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"     android:shareInterpolator="false"    >  <translate      android:duration="@integer/dialogplus_animation_default_duration"      android:fromXDelta="0%"      android:fromYDelta="0%"      android:toXDelta="0%"      android:toYDelta="100%"      /></set>

Style:

<style name="popup_window_animation">        <item name="android:windowEnterAnimation">@anim/slide_in_bottom</item>        <item name="android:windowExitAnimation">@anim/slide_out_bottom</item>    </style>

Method:

 private PopupWindow showOptions(Context mcon){        try{            LayoutInflater inflater = (LayoutInflater) mcon.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);            View layout = inflater.inflate(R.layout.popup_option_documents_type,null);            PopupWindow optionspu = new PopupWindow(layout, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);            optionspu.setAnimationStyle(R.style.popup_window_animation);            optionspu.setBackgroundDrawable(new ColorDrawable(Color.WHITE));            optionspu.setFocusable(true);            optionspu.setOutsideTouchable(true);            optionspu.update(0, 0, ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);            optionspu.showAtLocation(layout, Gravity.BOTTOM, 0, 0);            return optionspu;        }        catch (Exception e){e.printStackTrace();            return null;}    }
