Android 柱状图的实现 简单化的

xml代码：

Java代码：

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.github.mikephil.charting.charts.BarChart;
import com.github.mikephil.charting.components.XAxis;
import com.github.mikephil.charting.data.BarData;
import com.github.mikephil.charting.data.BarDataSet;
import com.github.mikephil.charting.data.BarEntry;
import com.github.mikephil.charting.utils.ColorTemplate;

import java.util.ArrayList;
import java.util.List;

public class Main2Activity extends AppCompatActivity {
    
    private BarChart barChart;
    //y轴数据
    private List list=new ArrayList<>();
    //数据的集合
    private BarDataSet dataSet1;
    //X轴
    private ArrayList lables=new ArrayList();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        barChart=findViewById(R.id.bt1);
       show();
    }
    //可视化数据
    private  void show()
    {
        list.add(new BarEntry(3f,0));
        list.add(new BarEntry(6f,1));
        list.add(new BarEntry(9f,2));
        //设置数组数据
        dataSet1=new BarDataSet(list,"第二组数据");
        //设置数组的颜色
        dataSet1.setColors(ColorTemplate.PASTEL_COLORS);
        //设置柱状图的字体大小
        dataSet1.setValueTextSize(20);
    
        lables.add("花费");
        lables.add("余额");
        lables.add("总工资");
        ArrayList dataSets=new ArrayList<>();
        dataSets.add(dataSet1);
        BarData barData=new BarData(lables,dataSets);
        barChart.setData(barData);
        
        barChart.getAxisLeft().setDrawLabels(true);
        barChart.getAxisRight().setDrawLabels(false);
        barChart.getXAxis().setDrawLabels(true);
        barChart.getXAxis().setPosition(XAxis.XAxisPosition.BOTTOM);
        barChart.setTouchEnabled(false);//触摸
        barChart.setDragEnabled(false);//拖拽
        barChart.setScaleEnabled(false);//缩放
        barChart.getXAxis().setLabelsToSkip(100);
        barChart.animateY(1000);
    }
}
