一：配置
1.在settings.gradle上加入maven配置
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
//引用通过JitPack.io发布的第三方库
maven { url 'https://www.jitpack.io' }
}
}
2.在bulid.gradle上加入代码，
implementation 'com.github.PhilJay:MPAndroidChart:v3.1.0'
点击syno什么的进行加载，在右上角
二：模板（调用别人的代码进行实现）
类：PieChartUtil
public class PieChartUtil {
public final int[] PIE_COLORS={
Color.rgb(181, 194, 202), Color.rgb(129, 216, 200), Color.rgb(241, 214, 145),
Color.rgb(108, 176, 223), Color.rgb(195, 221, 155), Color.rgb(251, 215, 191),
Color.rgb(237, 189, 189), Color.rgb(172, 217, 243)
};
private static PieChartUtil pieChartUtil;
private List<PieEntry> entries;
public static PieChartUtil getPitChart(){
if( pieChartUtil==null){
pieChartUtil=new PieChartUtil();
}
return pieChartUtil;
}
public void setPieChart(PieChart pieChart, Map<String, Float> pieValues, String title, boolean showLegend) {
pieChart.setUsePercentValues(true);//设置使用百分比（后续有详细介绍）
pieChart.getDescription().setEnabled(false);//设置描述
pieChart.setRotationEnabled(true);//是否可以旋转
pieChart.setHighlightPerTapEnabled(true);//点击是否放大
pieChart.setDrawCenterText(true);//设置绘制环中文字
pieChart.setDrawEntryLabels(true);
//这个方法为true就是环形图，为false就是饼图
pieChart.setDrawHoleEnabled(true);//环形
pieChart.setExtraOffsets(0, 0, 0, 0); //设置边距
// 0表示摩擦最大，基本上一滑就停
// 1表示没有摩擦，会自动转化为0.9999,及其顺滑
pieChart.setDragDecelerationFrictionCoef(0.35f);//设置滑动时的摩擦系数（值越小摩擦系数越大）
pieChart.setCenterText(title);//设置环中的文字
pieChart.setCenterTextSize(15f);//设置环中文字的大小
pieChart.setCenterTextColor(PIE_COLORS[2]);
pieChart.setRotationAngle(120f);//设置旋转角度
pieChart.setTransparentCircleRadius(61f);//设置半透明圆环的半径,看着就有一种立体的感觉
//设置环形中间空白颜色是白色
pieChart.setHoleColor(Color.TRANSPARENT);
//设置半透明圆环的颜色
pieChart.setTransparentCircleColor(Color.WHITE);
//设置半透明圆环的透明度
pieChart.setTransparentCircleAlpha(110);
//图例设置
Legend legend = pieChart.getLegend();
if (showLegend) {
legend.setEnabled(true);//是否显示图例
legend.setHorizontalAlignment(Legend.LegendHorizontalAlignment.CENTER);//图例相对于图表横向的位置
legend.setVerticalAlignment(Legend.LegendVerticalAlignment.TOP);//图例相对于图表纵向的位置
legend.setOrientation(Legend.LegendOrientation.HORIZONTAL);//图例显示的方向
legend.setDrawInside(false);
legend.setDirection(Legend.LegendDirection.LEFT_TO_RIGHT);//方向
} else {
legend.setEnabled(false);
}
//设置饼图数据
setPieChartData(pieChart, pieValues);
}
//设置饼图数据
private void setPieChartData(PieChart pieChart, Map<String, Float> pieValues) {
//遍历HashMap
Set set = pieValues.entrySet();
Iterator it = set.iterator();//得到适配器
entries=new ArrayList<>();
while (it.hasNext()) {
Map.Entry entry = (Map.Entry) it.next();
entries.add(new PieEntry(Float.valueOf(entry.getValue().toString()), entry.getKey().toString()));
}
PieDataSet dataSet = new PieDataSet(entries, "");
dataSet.setSliceSpace(3f);//设置饼块之间的间隔
dataSet.setSelectionShift(6f);//设置饼块选中时偏离饼图中心的距离
dataSet.setColors(PIE_COLORS);//设置饼块的颜色
dataSet.setValueTextSize(5f);
//设置数据显示方式有见图
dataSet.setValueLinePart1OffsetPercentage(80f);//数据连接线距图形片内部边界的距离，为百分数
dataSet.setValueLinePart1Length(0.3f);
dataSet.setValueLinePart2Length(0.4f);
dataSet.setValueLineColor( PIE_COLORS[3]);//设置连接线的颜色
dataSet.setYValuePosition(PieDataSet.ValuePosition.OUTSIDE_SLICE);//y轴数据显示在饼图内/外
dataSet.setXValuePosition(PieDataSet.ValuePosition.OUTSIDE_SLICE);//x轴数据显示在饼图内/外
PieData pieData = new PieData(dataSet);
pieData.setValueFormatter(new PercentFormatter());
pieData.setValueTextSize(11f);
pieData.setValueTextColor(Color.DKGRAY);
pieChart.setData(pieData);
pieChart.highlightValues(null);
pieChart.invalidate();
}
}
MainActivity:
public class MainActivity extends AppCompatActivity {
private PieChart pieChart;
private HashMap dataMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dataMap=new HashMap();
dataMap.put("Ⅰ类水","8");
dataMap.put("Ⅱ类水","12");
dataMap.put("Ⅲ类水","31");
dataMap.put("Ⅳ类水","24");
dataMap.put("Ⅴ类水","10");
dataMap.put("劣Ⅴ类水","15");
pieChart=(PieChart)findViewById(R.id.pie_chart);
PieChartUtil.getPitChart().setPieChart(pieChart,dataMap,"水质",true);
//点击事件
pieChart.setOnChartValueSelectedListener(new OnChartValueSelectedListener() {
@Override
public void onValueSelected(Entry e, Highlight h) {
PieEntry pieEntry=(PieEntry)e;
pieChart.setCenterText(pieEntry.getLabel());
}
@Override
public void onNothingSelected() {
}
});
}
}
xml布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
tools:context=".MainActivity">
<com.github.mikephil.charting.charts.PieChart
android:id="@+id/pie_chart"
android:padding="20dp"
android:layout_width="match_parent"
android:layout_height="300dp"/>
</LinearLayout>
这个模板的好处是不要数据库的内容，可以进行直接调用，然后注释齐全，可以自己定义
三：我的饼状图
这里包含了数据库，折线图等等的实现
public class Table extends AppCompatActivity {
private PieChart pieChart;
//折线图
private LineChart mChart;
private HashMap dataMap;
private int icount;
private int sum;
private String ArrayType[] = new String[]{"餐饮美食","生活日用","交通出行","休闲娱乐","医疗保健","投资理财","其他消费"};
private float MoneyType[] = new float[]{0,0,0,0,0,0,0};
private TextView textView;
//数据库命名
private project helper;
private SQLiteDatabase sqLiteDatabase;
@SuppressLint("MissingInflatedId")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_table);
pieChart = findViewById(R.id.pie_ch);
//条状图初始化控件
mChart = findViewById(R.id.line_chart);
//
textView = findViewById(R.id.Datashow);
initDate();
//设置数据
Setdata();
dataMap=new HashMap();
for (int i = 0;i < 7;i++)
{ if(MoneyType[i]!= 0)
dataMap.put(ArrayType[i],MoneyType[i]/sum);
}
PieChartUtil.getPitChart().setPieChart(pieChart,dataMap,"占有率",true);
//点击事件
pieChart.setOnChartValueSelectedListener(new OnChartValueSelectedListener() {
@Override
public void onValueSelected(Entry e, Highlight h) {
PieEntry pieEntry=(PieEntry)e;
pieChart.setCenterText(pieEntry.getLabel());
}
@Override
public void onNothingSelected() {
}
});
mChart.setTouchEnabled(false);
mChart.setDragEnabled(false);
mChart.setScaleEnabled(false);
mChart.setPinchZoom(false);
mChart.setDrawGridBackground(false);
mChart.getDescription().setEnabled(false);
Legend legend = mChart.getLegend();
legend.setEnabled(false);
XAxis xAxis = mChart.getXAxis();
xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
xAxis.setDrawGridLines(false);
xAxis.setGranularity(1f);
xAxis.setAxisMinimum(0f);
xAxis.setAxisMaximum(6f);
final String[] labels = new String[7];
for (int i = 0; i <7; i++) {
labels[i] = getPastDate(i);
}
xAxis.setValueFormatter(new IndexAxisValueFormatter(labels));
YAxis yAxis = mChart.getAxisLeft();
yAxis.setDrawGridLines(false);
yAxis.setGranularity(1f);
yAxis.setAxisMinimum(0);
yAxis.setAxisMaximum(1000);
//插入数据
