How to add animation to DialogFragment?

问题:

How can I add animation to DialogFragment. My animations are:

out anim:

<scale
    android:duration="200"
    android:fillAfter="false"
    android:fromXScale="1.0"
    android:fromYScale="1.0"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="-90%"
    android:startOffset="200"
    android:toXScale="0.5"
    android:toYScale="0.5" />

<translate
    android:duration="300"
    android:fromXDelta="0"
    android:fromYDelta="0"
    android:toXDelta="-200"
    android:toYDelta="-200" />

in anim:

<scale
    android:duration="200"
    android:fillAfter="false"
    android:fromXScale="0.5"
    android:fromYScale="0.5"
    android:interpolator="@android:anim/linear_interpolator"
    android:pivotX="50%"
    android:pivotY="-90%"
    android:toXScale="1.0"
    android:toYScale="1.0" />

<translate
    android:duration="300"
    android:fromXDelta="-200"
    android:fromYDelta="-200"
    android:toXDelta="0"
    android:toYDelta="0" />

and my code:

FragmentTransaction ft = getFragmentManager().beginTransaction();
                ft.setCustomAnimations(R.anim.jump_in, R.anim.jump_out, R.anim.jump_in, R.anim.jump_out);
                ft.add(layer_frag, "layer frag");
                ft.show(layer_frag).commit();//layer_frag is a class whitch extends DialogFragment

I must miss something because it appears as it appears before.

回答1:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) 
{
    final Dialog dialog = super.onCreateDialog(savedInstanceState);
    dialog.getWindow().getAttributes().windowAnimations = R.style.detailDialogAnimation;
    return dialog;
}

The answer was from stackoverflow.com/a/13537234/969325 but You have to set the style at onCreateDialog function.
