本项目为初学view练手只做，内部大量错误，请勿在项目中使用！ 存在问题如下：
1.在ondraw()方法中new 对象。
2.canvas.save() 以及canvas.rotate()更方便。
3.onDraw()内代码复杂。
add a CirclePercentView into your XML.
<com.wingsofts.panelview.PanelView
android:id="@+id/panelView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<com.wingsofts.panelview.PanelView
android:id="@+id/panelView2"
wing:arcColor="#EF1C63"
android:text="当前速度"
android:textSize="18sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
you can change percent by call method
setPercent();
setText();
setTextSize();
setArcColor();
setPointerColor();
setArcWidth();
