Android Dialog animation [duplicate]

Question

I'm trying to have a custom dialog appear as though it's sliding down from a text view. Is this possible? I can't seem to apply any animation to dialog class. I've tried this line in the constructor, but it has no effect:

this.getWindow().setWindowAnimations(R.anim.paranimation);

I'm not even sure if the animation is correct, but I will be able adjust it once I see what it's doing. I'll list it below for the sake of completeness. I'm not looking for help on the actual animation, just the application to the dialog.

paranimation.xml:

<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="-200%"
    android:toXDelta="0%"
    android:fromYDelta="200%"
    android:toYDelta="0%"
    android:duration="3000"
    android:zAdjustment="top">
</translate>

Answer 1

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.

To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings → Display → Animation) then the dialogs won't be animated no matter what you do!

The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="PauseDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
    </style>

    <style name="PauseDialogAnimation">
        <item name="android:windowEnterAnimation">@anim/spin_in</item>
        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
    </style>
</resources>

The windowEnterAnimation is one of my animations and is located in res\anim. The windowExitAnimation is one of the animations that is part of the Android SDK.

Then when I create the Dialog in my activities onCreateDialog(int id) method I do the following.

Dialog dialog = new Dialog(this, R.style.PauseDialog);

// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);

Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.

Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;

I have created the Fade in and Fade Out animation for Dialogbox using ChrisJD code.

1. Inside res/style.xml

   <style name="AppTheme" parent="android:Theme.Light" />
   <style name="PauseDialog" parent="@android:style/Theme.Dialog">
       <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
   </style>
   
   <style name="PauseDialogAnimation">
       <item name="android:windowEnterAnimation">@anim/fadein</item>
       <item name="android:windowExitAnimation">@anim/fadeout</item>
   </style>
   

2. Inside anim/fadein.xml

   <alpha xmlns:android="http://schemas.android.com/apk/res/android"
       android:interpolator="@android:anim/accelerate_interpolator"
       android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="500" />
   

3. Inside anim/fadeout.xml

   <alpha xmlns:android="http://schemas.android.com/apk/res/android"
       android:interpolator="@android:anim/anticipate_interpolator"
       android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="500" />
   

4. MainActivity

   Dialog imageDiaglog= new Dialog(MainActivity.this,R.style.PauseDialog);
