please squash your commits into one, and make the commit messages contains only English and meaningful.

Also, I see classes like 'TimeLineData', is this necessary or irrelevant? If the newly added classes are essential, please make an small introduction for what are they.

When further looking into the code, I wonder if you just put your project into this PR? If this is all about long press gestures, why there are so many new data classes and protocol like XMinMaxProvider and new chart like KlineChartView?

I'm closing this PR and please separate long press gestures changes only into a new PR. Thanks.
