StylePlayerView 控制器 xml 覆盖播放和暂停按钮不起作用

Question

我更新了我的项目 exoplayer 依赖项，并且我正在使用 StylePlayerView （来自 exoplayer 的自定义布局）参考更新我的代码，但是当我执行代码时，关于这 2 个按钮“播放”和“暂停”的高估不起作用，您使用 PLAY_PAUSE 并有效，但是我想自定义这个图标..所以如果有人可以帮助我，我真的很感激。psdt.-对我的英语感到抱歉，因为我说西班牙语。

我通过覆盖样式和可绘制对象解决了这个问题。我在我的值文件上创建了一个新样式，如下所示：

<style name="ExoStyledControls.Button.Center.PlayPause">
    <item name="android:src">@drawable/exo_styled_controls_pause</item>
    <item name="android:contentDescription">@string/exo_controls_play_description</item>
    <item name="android:padding">@dimen/exo_icon_padding</item>
</style>
<drawable name="exo_styled_controls_pause">@drawable/exo_styled_control_pause</drawable>
<drawable name="exo_styled_controls_play">@drawable/exo_styled_control_play</drawable>

可绘制对象 exo_styled_control_play 和 exo_styled_control_pause 应包含您自己的可绘制代码。
