Simple Video bullet screen function realization

I also read the blog before, relatively simple, more clear thinking, I used a lazy frame, do not do findbyid and monitoring events

Public classMainactivityextendsActivity {@BindView (r.id.Edit_text) EditTextEditText; @BindView (r.id.Send) ButtonSend; @BindView (r.id.Operation_layout) LinearLayoutOperationlayout; /*danmakucontext can be used to set the various global configurations of the barrage, such as setting the font, setting the maximum number of lines displayed, etc. */PrivateDanmakucontextDanmakucontext;Private BooleanShowdanmaku; @BindView (r.id.Video) VideoviewVideo;/* Video player */@BindView (r.id.Activity_main) relativelayoutActivitymain; @BindView (r.id.Danmaku_view) DanmakuviewDanmakuview; /* Parser for bullet screen */PrivateBasedanmakuparserParser=NewBasedanmakuparser () {@OverrideprotectedIdanmakus Parse () {return newDanmakus ();
