##使用方法，将PieChartView类和attr_pie_chart_view.xml文件直接拷贝到工程下，然后直接在xml布局中使用既可
<com.dahanis.piechart.PieChartView
android:id="@+id/pie_chart"

android:layout_height="400dp"
android:background="#ccc"
android:paddingBottom="40dp"
android:paddingLeft="20dp"
app:circleRadius="100dp"
app:textSize="13sp" />
- circleRadius:饼状图的半径
