弄出來的效果圖為：

不廢話，直接上程式碼了：
1.佈局檔案：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <lecho.lib.hellocharts.view.PieChartView
 
        android:id="@+id/piechart"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
    </lecho.lib.hellocharts.view.PieChartView>
</LinearLayout>

2.activity程式碼：

public class PieChartActivity extends AppCompatActivity {

    @BindView(R.id.piechart
 
)
    PieChartView piechart;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_piechart);
        ButterKnife.bind(this);

        //為piechart設定屬性
        ViewGroup.LayoutParams layoutParams = piechart.getLayoutParams
 
();
        layoutParams.height = AppUtil.dp2px(this, 180) ;
        layoutParams.width = AppUtil.getScreenWidth(this);
        piechart.setLayoutParams(layoutParams);//設定寬高
        piechart.setViewportCalculationEnabled(true);//設定餅圖自動適應大小
        piechart.setChartRotationEnabled(false);//設定餅圖是否可以手動旋轉

       //例項化PieChartData物件
        final PieChartData  pd = new PieChartData();
        pd.setHasLabelsOutside(false);//設定餅圖外面是否顯示值
        pd.setHasCenterCircle(true);//設定餅圖中間是否有第二個圈
        pd.setCenterCircleColor(getResources().getColor(R.color.colorWhite));//設定餅圖中間圈的顏色
        pd.setCenterCircleScale(0.7f);////設定第二個圈的大小比例

        Typeface typeface = Typeface.create("typeface", Typeface.BOLD_ITALIC);//設定文字字型,BOLD_ITALIC粗斜體
        pd.setCenterText1Typeface(typeface);
        pd.setCenterText1Color(getResources().getColor(R.color.colorPrimary));
        pd.setCenterText1FontSize(16);
        //pd.setCenterText1("總投訴事項");

        pd.setCenterText2Color(getResources().getColor(R.color.colorRed));
        pd.setCenterText2FontSize(16);

        pd.setValueLabelsTextColor(Color.BLACK);//設定顯示值的字型顏色
        //pd.setSlicesSpacing(int sliceSpacing);//設定資料間的間隙
        //pd.setHasLabelsOnlyForSelected(true);//設定當值被選中才顯示
        //pd.hasLabelsOutside();
        pd.setHasLabels(false);
        pd.setValueLabelsTextColor(getResources().getColor(R.color.colorWhite));

        //初始化餅圖資料 new SliceValue(float value, int color).setLabel(String label)
        final List<SliceValue> sliceList = new ArrayList<SliceValue>();
        for( int i = 1; i <= 10 ; i++){
            sliceList.add(new SliceValue( i,getResources().getColor(R.color.pie_normal)).setLabel( String.valueOf( i) + "沒有名字"));
        }
        pd.setValues(sliceList);//為餅圖新增資料
        piechart.setPieChartData(pd);//為餅圖設定資料

        //將第一個不為0值預設選中()
        SliceValue defaultValue = sliceList.get(0);
        defaultValue.setColor(getResources().getColor(R.color.pie_selected));
        if( defaultValue.getValue() < 0 ){
            pd.setCenterText1("0 沒有名字");
            pd.setCenterText2((int) defaultValue.getValue() + "項");
        }else{
            pd.setCenterText1(String.valueOf(defaultValue.getLabel()));
            pd.setCenterText2((int) defaultValue.getValue() + "項");
        }
        piechart.startDataAnimation();

        //為餅圖新增觸屏相應事件
        piechart.setOnValueTouchListener(new PieChartOnValueSelectListener() {
            @Override
            public void onValueSelected(int i, SliceValue sliceValue) {
                for (int j = 0; j < sliceList.size(); j++) {
                    if (i == j) {
                        sliceList.get(j).setColor(getResources().getColor(R.color.pie_selected));
                    } else {
                        sliceList.get(j).setColor(getResources().getColor(R.color.pie_normal));
                    }
                }
                pd.setCenterText1(String.valueOf(sliceList.get(i).getLabel()));
                pd.setCenterText2((int) sliceList.get(i).getValue() + "項");
                piechart.startDataAnimation();
            }

            @Override
            public void onValueDeselected() {

            }
        });

    }
}
