Show DialogFragment with animation growing from a

Question

I'm showing a DialogFragment when the user taps on a row in a ListView. I'd like to animate the showing of the dialog so that it grows from the center of the row. A similar effect can be seen when opening a folder from the launcher.

One idea that I've had is a combination of TranslateAnimation and ScaleAnimation. Is there another way?

Answer 1

Use decor view inside onStart in your dialog fragment

@Override
public void onStart() {
    super.onStart();


    final View decorView = getDialog()
            .getWindow()
            .getDecorView();

    decorView.animate().translationY(-100)
            .setStartDelay(300)
            .setDuration(300)
            .start();

}

Check it out this code, it works for me

// Slide up animation

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

    <translate
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromYDelta="100%"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toXDelta="0" />

</set>

// Slide dowm animation

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

    <translate
        android:duration="@android:integer/config_mediumAnimTime"
        android:fromYDelta="0%p"
        android:interpolator="@android:anim/accelerate_interpolator"
        android:toYDelta="100%p" />

</set>

// Style

<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_up</item>
    <item name="android:windowExitAnimation">@anim/slide_down</item>
</style>

// Inside Dialog Fragment

@Override
public void onActivityCreated(Bundle arg0) {
    super.onActivityCreated(arg0);
    getDialog().getWindow()
    .getAttributes().windowAnimations = R.style.DialogAnimation;
}
