为 Pre-Lollipop 设备创建 Circular Reveal

Question

首先，这不是同一个问题

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();

圆形显示没有显示。我的意思是代码执行时没有任何反应。

然而，如果视图在 XML 文件中设置为可见，则圆形显示确实有效，但问题是如果我将视图“circBack”设置为在 XML 中可见，它从应用程序启动的那一刻开始显示，这很正常。

这个问题有什么解决办法吗？

Answer 1

看起来您正在 "Gone" 视图上初始化此动画？

尝试获取视图的可见性并确保运行它在

内

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

代码块。

Answer 2

好吧，这可能是 Gradle 依赖项的问题，因为当我以这种方式添加库时它起作用了，

错误的方式

dependencies {
    compile ('com.github.ozodrukh:CircularReveal:2.0.1@aar') {
        transitive = true;
    }
}

正道

dependencies {
    compile 'com.github.ozodrukh:CircularReveal:2.0.1'
}

抱歉回答晚了。希望对有需要的人有所帮助。
