Animation max size

I have animation with following spec:

  "v": "4.5.6",
  "fr": 25,
  "ip": 0,
  "op": 38,
  "w": 360,
  "h": 146,
  "ddd": 0,
.......

I want to achieve behavior when animation view fits on screen width. If i set to LottieAnimationView layout_width=“match_parent” and layout_height=“wrap_content” i faced with following issue on phones: if phone’s width is 1440px(samsung s7), animation viewport width is 1000px because of LottieComposition MAX_PIXELS = 1000 constraint. So i got space between animation and screen edge. I solved this issue by dynamically changing view height to proper value:

DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
		float dpWidth = displayMetrics.widthPixels / displayMetrics.density;
		float dpHeight = displayMetrics.heightPixels / displayMetrics.density;
		mLottieAnimationView.getLayoutParams().height = (int) (displayMetrics.density * 146f / (360f / dpWidth));

After applying new height on view, animation viewport fits screen width well. So my question is this fix save in terms of stability and performance? PS: i don’t have masks or mattes.

Use centerCrop instead of center.

I think I face the same issue. My layout:

<LinearLayout android:background="#00ffffff" android:layout_height="match_parent" android:layout_width="match_parent" xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"> <com.airbnb.lottie.LottieAnimationView android:id="@+id/animation_view" android:layout_gravity="center" android:scaleType="center" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout>

And I set this into a view with a fixed width that is higher than the file width. The LottieAnimationView fills out the whole space (setting a background color to prove it) but the animation is still small in the middle of the view. A “autoScale” switch would be nice to have it fill up the space

I set up width in dp that’s equal to device width and it scale perfectly good. It doesn’t work same with android:layout_width="match_parent".
