Question

在此布局中，我使用水平图表和ratingBar小部件。我希望每个条形都位于其自己的ratingBar前面。我更改了图表的barWidth，但是无法调整布局。这是我的xml布局：

 <LinearLayout
                            android:id="@+id/layoutRating"

这是我想要的输出：

这是我设置图表的代码：

 private void setGraph(){
    mBinding.barChart.getDescription().setEnabled(false);

    mBinding.barChart.setDrawBarShadow(false);
    mBinding.barChart.getLegend().setEnabled(false);

    XAxis xAxis=mBinding.barChart.getXAxis();
    xAxis.setDrawGridLines(false);
    xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
    xAxis.setEnabled(true);
    xAxis.setDrawAxisLine(false);

    YAxis yAxis=mBinding.barChart.getAxisLeft();
    yAxis.setAxisMaximum(100f);
    yAxis.setAxisMinimum(0f);
    yAxis.setEnabled(false);

    xAxis.setLabelCount(5);


    YAxis yRight=mBinding.barChart.getAxisRight();
    yRight.setDrawAxisLine(true);
    yRight.setDrawGridLines(false);
    yRight.setEnabled(false);

    mBinding.barChart.animateY(2000);

}
private void setDataChart(){
    ArrayList<String> percentageEachRating=currentCourse.getPercentageEachRating();
    ArrayList<BarEntry> entries=new ArrayList<>();
    float barWidth=1f;
    float spaceForBar=7f;
    for (int i=0;i<percentageEachRating.size();i++){
        float val=Float.valueOf(percentageEachRating.get(i));
        entries.add(new BarEntry(i*spaceForBar,val));
    }

    BarDataSet set=new BarDataSet(entries,"Data set1");
    set.setDrawValues(false);
    set.setColors(ContextCompat.getColor(getContext(),R.color.colorRateOne),
            ContextCompat.getColor(getContext(),R.color.colorRateTwo),
            ContextCompat.getColor(getContext(),R.color.colorRateThree),
            ContextCompat.getColor(getContext(),R.color.colorRateFour),
            ContextCompat.getColor(getContext(),R.color.colorRateFive));
    mBinding.barChart.setDrawBarShadow(true);
    set.setBarShadowColor(Color.argb(40,150,150,150));
    BarData data=new BarData(set);
    data.setBarWidth(barWidth);
    mBinding.barChart.setData(data);
    mBinding.barChart.invalidate();
}
