我正在关注{＆3;}＆＃34; T＆＃34;但是当我运行应用程序时，我在logcat中收到以下消息。我不确定出了什么问题，因为班级应该在那里吗？
无法找到方法android.view.ViewAnimationUtils.createCircularReveal，从方法io.codetail.animation.ViewAnimationUtils.createCircularReveal

对于其他任何可能看到这个与揭示动画/菜单的相同问题没有显示的人，这就是我解决问题的方法。 RevealFrameLayout并没有显示出来，它只是显示在其他一切之后。因此，正如您在下面的布局中所看到的，我只是将FrameLayout移到了所有其他内容之下，现在它完美无瑕。
主要布局

android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main" />
//Issue was solved by adding the FrameLayout here.
//below all other content. Works perfectly now.
<FrameLayout

android:layout_height="wrap_content">
<include layout="@layout/reveal_layout" />
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
答案 1 :(得分：0)
检查导入的库。
在我的情况下，
void countBase(char *p)
{
int aCount = 0, cCount = 0, tCount = 0, gCount = 0;
char invalidBase[100];
int i, j=0;
while(*p != '\0')
{
if(*p == 'A' || *p == 'a')
{
aCount++;
}
else if(*p == 'C' || *p == 'c')
{
cCount++;
}
else if(*p == 'T' || *p == 't')
{
tCount++;
}
else if(*p == 'G' || *p == 'g')
{
gCount++;
}
else
{
invalidBase[j] = *p;
}
j++;
p++;
}
for(i = 0; invalidBase[i] != '\0'; i++)
{
printf("Invalid Base: %c\n", invalidBase[i]);
}
printf(" A: %i\n C: %i\n T: %i\n G: %i\n", aCount, cCount, tCount, gCount);
}
没有错误发生。
答案 2 :(得分：0)
正如图书馆明确提到你应该首先添加远程maven网址：
repositories {
maven {
url "https://jitpack.io"
}
}
然后是库依赖项：
compile ('com.github.ozodrukh:CircularReveal:1.3.1@aar') {
transitive = true;
}
现在尝试构建项目并同步gradle！如果这没有帮助，请将aar版本更改为1.1.1
compile ('com.github.ozodrukh:CircularReveal:1.1.1@aar') {
transitive = true;
}
看看它是否有帮助。
如果问题仍然存在，我建议您阅读this博客！
答案 3 :(得分：0)
虽然，我无法弄清楚你为什么会收到错误，因为我没有尝试过该库，但我认为你可以轻松地实现循环显示而不使用上面的库。请查看Material-Animations，它有一个非常简洁的圆形显示工作示例，您可以轻松使用。
答案 4 :(得分：0)
让我猜一下，您正在测试前Lollipop设备/模拟器上的代码（并获得该错误）。
类别ViewAnimationUtils已在Android 21 SDK（Lollipop）中引入。
您的minSdkVersion是16。看看this其他问题，建议支持库将圆形揭示动画带回Android 2.3。该库是CircularReveal。您必须分叉io.codetail.animation.ViewAnimationUtils才能使用它。
从方法引用 io.codetail.animation.ViewAnimationUtils.createCircularReveal
编辑2：在看到更新的响应并且从OP知道logcat不是错误而只是警告
之后这根本不是问题。这是一个Dalvik功能，它会检查缺少的类/方法，并在没有找到它们时发出警告。除非你真的试图调用它们，否则它不会崩溃。
OkHttp库有类似警告，您可以看到they also say您可以忽略它们。
作为旁注，CircularReveal库似乎use @TargetApi注释应该使用@SuppressLint("NewApi")。 @TargetApi表示您应该仅从该Api级别调用该方法。无论如何，这不是警告的原因，因为此信息仅在编译时可用。
