首先,这与为 pre-Lollipop 设备 (Android) 创建循环显示不同的问题
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>
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();
圆形显示不显示。我的意思是当代码执行时什么都没有发生。

但是,如果视图在 XML 文件中设置为可见,则循环显示确实有效,但问题是如果我将视图“ circBack ”设置为在 XML 中可见,它会从应用程序启动的那一刻开始显示,这很常见.
这个问题有什么解决办法吗?
