Answer 1

尝试这种方式

  

在layout.xml文件中

<com.github.mikephil.charting.charts.LineChart
     android:id="@+id/chart"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"/>

  

在Activity.java中

LineChart lineChart = (LineChart) findViewById(R.id.chart);
.
.
.
  XAxis xAxis = lineChart.getXAxis();
        xAxis.setDrawAxisLine(true);
        xAxis.setDrawGridLines(true)
xAxis.setGridColor(getResources().getColor(R.color.colorAccent));

.
.
.
 YAxis yAxisRight = lineChart.getAxisRight();
        yAxisRight.setDrawAxisLine(true);
        yAxisRight.setDrawGridLines(true);
yAxisRight.setGridColor(getResources().getColor(R.color.colorAccent));
.
.
.
 YAxis yAxisLeft = lineChart.getAxisLeft();
        yAxisLeft.setDrawGridLines(true);
yAxisLeft.setGridColor(getResources().getColor(R.color.colorAccent));

您可以覆盖AxisRenderer.drawGridLine并更改网格线的宽度。

private class CustomXAxisRenderer(
    viewPortHandler: ViewPortHandler,
    xAxis: XAxis,
    trans: Transformer
) : XAxisRenderer(viewPortHandler, xAxis, trans) {

    override fun drawGridLine(c: Canvas?, x: Float, y: Float, gridLinePath: Path?) {
        mGridPaint.strokeWidth = (if (x.toInt() % 5 == 0) 2 else 1).toFloat()
        super.drawGridLine(c, x, y, gridLinePath)
    }

}

...

chart.setXAxisRenderer(CustomXAxisRenderer(mViewPortHandler, mXAxis, mLeftAxisTransformer))
