推荐答案

这是我的答案！

ContentLoadingProgressbar等待最短的时间被消散，然后在0.5秒内使用hide()进行显示，因此即使show()被调用，也可以在显示在屏幕上之前将其消灭.

ContentLoadingProgressbar waits a minimum time to be dismissed before showing using hide() like with-in 0.5 seconds.So even the show() gets called this can be dismissed before it appear on the screen.

它可以防止在幼稚"的实现中很快出现的闪烁现象.

It prevents very fast flickering stuff that you might see with "naive" implementations.

是

<android.support.v4.widget.ContentLoadingProgressBar
        android:id="@+id/address_looking_up"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:visibility="visible" />

使用android:theme替换样式 https://stackoverflow.com/a/38282149/5188159
