我正在使用 MPAndroidChart库。我想自定义MPAndroidChart的图例。在MPAndroidChart库中,我尝试通过以下代码legend.setPosition(LegendPosition.BELOW_CHART_CENTER)来设置图例的位置,但无法实现。 我需要将图例设置为以下图像所示。
感谢您的帮助
感谢您的帮助
Legend
,并且自己构思实现方式。chart.getLegend().setEnabled(false)
ListView
,从图表的Legend
对象中获取数据并显示它。getColors()
,getLegendLabels()
),并将它们用于在ListView
中显示。步骤1
Legend legend = mChart.getLegend();
步骤二
int colorcodes[] = legend.Colors();
步骤 3
for (int i = 0; i < legend.Colors().length-1; i++) {
.....
.....
}
步骤 4
然后,您需要选择水平或垂直布局,并获取图例颜色代码和图例标签,根据图例长度创建布局和标签。下面是代码示例:
LinearLayout.LayoutParams parms_left_layout = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
parms_left_layout.weight = 1F;
LinearLayout left_layout = new LinearLayout(context);
left_layout.setOrientation(LinearLayout.HORIZONTAL);
left_layout.setGravity(Gravity.CENTER);
left_layout.setLayoutParams(parms_left_layout);
LinearLayout.LayoutParams parms_legen_layout = new LinearLayout.LayoutParams(
20, 20);
parms_legen_layout.setMargins(0, 0, 20, 0);
LinearLayout legend_layout = new LinearLayout(context);
legend_layout.setLayoutParams(parms_legen_layout);
legend_layout.setOrientation(LinearLayout.HORIZONTAL);
legend_layout.setBackgroundColor(colorcodes[i]);
left_layout.addView(legend_layout);
TextView txt_unit = new TextView(context);
txt_unit.setText(legend.getLabel(i));
left_layout.addView(txt_unit);
LinearLayout.LayoutParams parms_middle_layout = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
parms_middle_layout.weight = 1F;
LinearLayout middle_layout = new LinearLayout(this);
middle_layout.setOrientation(LinearLayout.HORIZONTAL);
middle_layout.setGravity(Gravity.CENTER);
middle_layout.setLayoutParams(parms_middle_layout);
TextView txt_leads = new TextView(this);
txt_leads.setText("450");
middle_layout.addView(txt_leads);
LinearLayout.LayoutParams parms_right_layout = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
parms_right_layout.weight = 1F;
LinearLayout right_layout = new LinearLayout(this);
right_layout.setOrientation(LinearLayout.HORIZONTAL);
right_layout.setGravity(Gravity.CENTER);
right_layout.setLayoutParams(parms_right_layout);
TextView txt_leads_percentage = new TextView(this);
txt_leads_percentage.setText(munit_percentage_list.get(i) + "");
right_layout.addView(txt_leads_percentage);
childlayout.addView(left_layout);
childlayout.addView(middle_layout);
childlayout.addView(right_layout);
接下来,在主布局中添加您在运行时创建的(子布局)。

https://github.com/PhilJay/MPAndroidChart/issues/3934#issuecomment-386039451 - itabdullah设置自定义图例:
public void setLegends(){
Legend l = holder.pieChart.getLegend();
l.getEntries();
l.setPosition(Legend.LegendPosition.BELOW_CHART_CENTER);
l.setYEntrySpace(10f);
l.setWordWrapEnabled(true);
LegendEntry l1=new LegendEntry("Male",Legend.LegendForm.CIRCLE,10f,2f,null,Color.YELLOW);
LegendEntry l2=new LegendEntry("Female", Legend.LegendForm.CIRCLE,10f,2f,null,Color.RED);
l.setCustom(new LegendEntry[]{l1,l2});
l.setEnabled(true);

public void setCustomLegend(){
int colorcodes[] = l.getColors();
Context context = DistributorGraphActivity.this;
for (int i = 0; i < l.getColors().length - 1; i++) {
LayoutInflater inflater = getLayoutInflater();
TableRow tr = (TableRow) inflater.inflate(R.layout.table_row_legend,
childlayout, false);
childlayout.addView(tr);
LinearLayout linearLayoutColorContainer=(LinearLayout) tr.getChildAt(0);
LinearLayout linearLayoutColor= (LinearLayout) linearLayoutColorContainer.getChildAt(0);
TextView tvLabel = (TextView) tr.getChildAt(1);
TextView tvAmt = (TextView) tr.getChildAt(2);
linearLayoutColor.setBackgroundColor(colorcodes[i]);
tvLabel.setText(l.getLabel(i));
tvAmt.setText(arrListDealerGraph.get(i).getAmt());
}
mChart.getLegend().setWordWrapEnabled(true);
mChart.getLegend().setEnabled(false);
}
对于 Kotlin,命令是:
mChart.legend.isEnabled = false
