Android的VideoView - 检测视频中的时间点 [英] Android VideoView - Detect point of time in video

问题描述

我使用的是VideoView显示视频。我使用西顿preparedListener和setOnCompletionListener前后的视频开始和结束后做的东西。

I am using a VideoView to display a video. I am using setOnPreparedListener and setOnCompletionListener to do stuff before and after the video starts and ends.

我想知道我怎么能去检测一些时间点的视频。对于例如，说我想要写日志到文件时的视频已经打了10秒。我怎样才能检测出10秒大关？

I was wondering how I could go about detecting some point of time in the video. For eg, say I want to write log to a file when the video has played for 10s. How can I detect the 10s mark?

谢谢 克里斯

推荐答案

第1步：使用 postDelayed（）或有所收获控制每一秒左右

Step #1: Use postDelayed() or something to get control every second or so.

步骤＃2：检查 getCurrentPosition（）键，看看是不是靠近你想要的标记点。如果是这样，你的处理。

Step #2: Check getCurrentPosition() and see if it is near your desired marker point. If so, do your processing.

第三步：车床，漂洗，重复

Step #3: Lather, rinse, repeat.

没有任何机制为Android调入您特别是当一个特定的时间点出现在视频中，所以你必须凑合着用轮询机制。

There is no mechanism for Android to call into you specifically when a certain point in time has occurred in the video, so you have to make do with a polling mechanism.
