推荐答案
您不能在Android中做到这一点。事实上，你不能复制，当一个实例已在运行的任何记录实例，这适用于摄像头以及麦克风。
在输出的情况下，如音频播放（和视频显示），有模块来处理多个数据流，混合，重新取样等（作曲，渲染显示）。
You cannot do this in android. In fact you cannot duplicate any record instance when one instance is already running , this applies to camera as well as mic. In case of output , like audio playout (and video display) there are modules to handle multiple streams, mix , resample etc (composing, rendering for display).
如果您有充分的Android源$ C $ C为您的设备，你可以尝试写一个缓冲机制，但不是通用的，可扩展的，并不简单。
If you have the full android source code for your device,you can try to write a buffering mechanism, but that is not generic, scalable and is not simple.
在一般如果记录对象实例被打开，并举行由其它应用程序，有没有什么可以做其他的，而不是显示错误消息。
（快速实验 - 在后台录制音频和键盘打开语音转换器，它抛出了一个错误）
In general if the recording object instance is opened and held by another application, there is nothing much you can do other than to display an error message. (Quick experiment- Record audio in the background and open the speech converter in your keyboard, it throws up an error)
