在上述代码中设置当直播画面realplay_sv在开始播放的时候隐藏就android:id="@+id/liveProgressBar"这个加载图标，当手机是竖屏的时候隐藏android:id="@+id/ll_hc"这一模块中的8个按钮以及android:id="@+id/ib_rotate2"这一个按钮，其他正常显示。当手机是横屏的时候隐藏android:id="@+id/rl_control"这一模块所有布局，其他正常显示。
本文详细解释了Android开发中android:layout_gravity与android:gravity属性的区别及应用，包括它们各自的含义、可选值及其组合使用方式，并针对LinearLayout的不同方向设置进行了具体说明。
