首先,这与前Lollipop设备(Android)的创建循环显示不同
我正在使用那里提到的库来创建Circular Reveal,但它似乎对我不起作用.
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>

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();
