####饼状图图形报表控件，可自行设定多种参数

##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_width="match_parent"
              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
• textSize:指示文字的大小

##java类中的使用

        PieChartView pieChartView = (PieChartView) findViewById(R.id.pie_chart);

        List<PieChartView.PieceDataHolder> pieceDataHolders = new ArrayList<>();

        pieceDataHolders.add(new PieChartView.PieceDataHolder(100,0xFF77CCAA, "今天，１"));
        pieceDataHolders.add(new PieChartView.PieceDataHolder(1000, 0xFF11AA33, "明天，２"));
