Question

添加了用于显示加载效果的库，但它不可见或看不到任何效果。虽然没有发生错误，但是在网络呼叫开始时没有看到效果。 show方法没有任何效果。目前我使用的是Android 4.1.2版。

Answer 1

解决了这个问题。忘了提到默认的白色的indiacator颜色，所以装载机实际上工作但是看不见;

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" />

Answer 2

您的父级布局为LinearLayout，请尝试使用RelativeLayout包装主布局，并将AVLoadingIndicatorView放在LinearLayout

之外

AVLoadingIndicatorView库在app中不可见
