Android custom view’s custom rating control, ratingbar, implements custom star size and spacing

In Android development, we often use the evaluation of businesses or commodities and use stars to score. However, the rating bar, which comes with the scoring control in the Android system, is particularly difficult to use, and the spacing and size cannot be changed. Therefore, I customized a particularly easy-to-use scoring control. It can be used directly in the project, especially simple. The following is directly above:
