查看了一些大神的帖子，学习了很多：

弄出来的效果图为：

不废话，直接上代码了：
1.布局文件：

<?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代码：

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);        //为piechart设置属性        ViewGroup.LayoutParams layoutParams = piechart.getLayoutParams();        layoutParams.height = AppUtil.dp2px(this, 180) ;        layoutParams.width = AppUtil.getScreenWidth(this);        piechart.setLayoutParams(layoutParams);//设置宽高        piechart.setViewportCalculationEnabled(true);//设置饼图自动适应大小        piechart.setChartRotationEnabled(false);//设置饼图是否可以手动旋转       //实例化PieChartData对象        final PieChartData  pd = new PieChartData();        pd.setHasLabelsOutside(false);//设置饼图外面是否显示值        pd.setHasCenterCircle(true);//设置饼图中间是否有第二个圈        pd.setCenterCircleColor(getResources().getColor(R.color.colorWhite));//设置饼图中间圈的颜色        pd.setCenterCircleScale(0.7f);////设置第二个圈的大小比例        Typeface typeface = Typeface.create("typeface", Typeface.BOLD_ITALIC);//设置文本字体,BOLD_ITALIC粗斜体        pd.setCenterText1Typeface(typeface);        pd.setCenterText1Color(getResources().getColor(R.color.colorPrimary));        pd.setCenterText1FontSize(16);        //pd.setCenterText1("总投诉事项");        pd.setCenterText2Color(getResources().getColor(R.color.colorRed));        pd.setCenterText2FontSize(16);        pd.setValueLabelsTextColor(Color.BLACK);//设置显示值的字体颜色        //pd.setSlicesSpacing(int sliceSpacing);//设置数据间的间隙        //pd.setHasLabelsOnlyForSelected(true);//设置当值被选中才显示        //pd.hasLabelsOutside();        pd.setHasLabels(false);        pd.setValueLabelsTextColor(getResources().getColor(R.color.colorWhite));        //初始化饼图数据 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) + "没有名字"));        }        pd.setValues(sliceList);//为饼图添加数据        piechart.setPieChartData(pd);//为饼图设置数据        //将第一个不为0值默认选中()        SliceValue defaultValue = sliceList.get(0);        defaultValue.setColor(getResources().getColor(R.color.pie_selected));        if( defaultValue.getValue() < 0 ){            pd.setCenterText1("0 没有名字");            pd.setCenterText2((int) defaultValue.getValue() + "项");        }else{            pd.setCenterText1(String.valueOf(defaultValue.getLabel()));            pd.setCenterText2((int) defaultValue.getValue() + "项");        }        piechart.startDataAnimation();        //为饼图添加触屏相应事件        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() + "项");                piechart.startDataAnimation();            }            @Override            public void onValueDeselected() {            }        });    }}
