添加了显示加载效果的库，但它不可见或没有看到任何效果。虽然没有发生错误，但是在网络调用开始时没有看到任何效果。 show 方法没有任何效果。目前我正在使用 android 版本 4.1.2。

最佳答案
解决了这个问题。忘记提及默认情况下为白色的指示器颜色，因此加载器实际上在工作但不可见；
XML代码
<com.wang.avi.AVLoadingIndicatorView
android:id="@+id/avi"
style="@style/AVLoadingIndicatorView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="gone"
app:indicatorColor="@color/colorPrimaryDark"
app:indicatorName="LineSpinFadeLoaderIndicator" />
关于android - AVLoadingIndicatorView 库在应用程序中不可见，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43040457/
