I'm trying to do a scale in/out animation for activity/framgent transition
here are the two animations :
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:interpolator="@android:anim/accelerate_decelerate_interpolator" >
<scale
android:fromXScale="80%"
android:fromYScale="80%"
android:toXScale="80%"
android:toYScale="80%" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.5" />
</set>
-
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="500"
android:interpolator="@android:anim/accelerate_decelerate_interpolator" >
<translate
android:fromXDelta="100%"
android:fromYDelta="0"
android:toXDelta="0"
android:toYDelta="0" />
</set>
Use it like that :
overridePendingTransition(R.anim.slide_in_right, R.anim.slide_to_behind);
The problem is that the activity doesn't scale down in the center of the screen, it stick to the top/left of the screen
Any idea what wm i missing ? Or doing wrong ?
Add a pivot to your scale animation. Add this on your xml:
android:pivotX="50%"
android:pivotY="50%"
Your scale should look like:
<scale
android:fromXScale="100%"
android:fromYScale="100%"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="80%"
android:toYScale="80%" />
