Create Circular Reveal for Pre-Lollipop Devices

Question

First thing's first, this is not the same question as Create circular reveal for pre-Lollipop devices (Android)

I am using the library mentioned there to create Circular Reveal, but it doesn't seem to work for me.

XML

<io.codetail.widget.RevealFrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <FrameLayout
            android:id="@+id/circBack"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#ff4081"
            android:visibility="invisible"
            ></FrameLayout>
</io.codetail.widget.RevealFrameLayout>

JAVA

                View myView = findViewById(R.id.circBack);


                // get the center for the clipping circle
                int cx = (myView.getLeft() + myView.getRight()) / 2;
                int cy = (myView.getTop() + myView.getBottom()) / 2;

                // get the final radius for the clipping circle
                int finalRadius = Math.max(myView.getWidth(), myView.getHeight());


                SupportAnimator animator = ViewAnimationUtils.createCircularReveal(myView, cx, cy, 0, finalRadius);
                animator.setInterpolator(new AccelerateDecelerateInterpolator());
                animator.setDuration(1000);
                myView.setVisibility(View.VISIBLE);
                animator.start();

The circular reveal doesn't show up. I mean nothing happens when the code executes.

Logcat shows this

However the circular reveal does work if the view is set to visible in the XML files, but the problem is if I set the view "circBack" to visible in the XML, it shows up from the moment the app is launched, which is usual.

Any solution to this problem?

Answer 1

Look like you're initializing this animation on "Gone" view ?

Try to get view's visibilty and make sure that you run it inside

if (mView.getVisibility() == View.VISIBLE)
{
..
..
  anim.start();
}

block of code.
