但是有两个问题.第一个是ExoPlayer似乎没有提供任何Control类,因此您可以简单地添加一个按钮并覆盖其功能.
我想我必须在视频顶部显示该按钮,所以我可能必须将它们包装在FrameLayout中并为按钮添加gravity = bottom或者是否有另一种方式？
第二个问题是：如果用户点击全屏按钮,我接下来该怎么办？全屏添加另一个片段与视频视图？但是,如何从用户点击按钮开始播放视频,而不是从头开始播放？我无法在exoPlayer中找到与特定时间相关的任何内容.
解决方法
Attributes
The following attributes can be set on a
SimpleExoPlayerViewwhen used in a layout XML file:
…controller_layout_id – Specifies the id of the layout resource to be inflated by the child
PlaybackControlView. See below for more details.…
因此,基本上您可以为控制器提供自己的布局文件(您可以复制文档中提到的exo_playback_control_view布局,这是默认布局文件,并根据需要自定义.请注意,您需要提供相同的视图ID现有的控件(所以最好实际复制它),如PlaybackControlView的文档中所述：
Overriding the layout file
To customize the layout of
PlaybackControlViewthroughout your app,or just for certain configurations,you can define exo_playback_control_view.xml layout files in your application res/layout* directories. These layouts will override the one provided by the ExoPlayer library,and will be inflated for use byPlaybackControlView. The view identifies and binds its children by looking for the following ids:
exo_play – The play button.
@H_404_31@exo_pause – The pause button.
@H_404_31@exo_ffwd – The fast forward button.
@H_404_31@exo_rew – The rewind button.
@H_404_31@exo_prev – The prevIoUs track button.
@H_404_31@exo_next – The next track button.
@H_404_31@exo_position – Text view displaying the current playback position.
@H_404_31@exo_duration – Text view displaying the current media duration.
@H_404_31@exo_progress – Seek bar that’s updated during playback and allows seeking.
@H_404_31@All child views are optional and so can be omitted if not required,however where defined they must be of the expected type.
以下是带全屏按钮的自定义布局.您可以通过view.findViewById(R.id.exo_fullscreen_button)获取对该按钮的引用,并将OnClickListener附加到该按钮.在onClick()中你可以开始你的全屏活动(你可以在AndroidManifest.xml中或以编程方式定义它的全屏)或显示另一个片段,其中SimpleExoPlayerView占据整个屏幕.
从第二点开始,您可以像这样获得播放位置：playbackPosition = player.getCurrentPosition()并将其作为Intent extra传递给新的全屏Activity / Fragment.然后,在全屏活动/片段中加载视频,提取该playbackPosition值并调用：
player.seekTo(playbackPosition); player.setPlayWhenReady(true);
这是控件布局文件：
