Java Making imitation micro-letter recording small video control _java

This article is a control that uses Mediarecorder to record small video, you can set the time, space size of the video recording, and whether to turn on the camera at the beginning. This control is a composite control that inherits from LinearLayout and implements the Android.media.MediaRecorder.OnErrorListener interface to prevent errors.
