我正在使用 MPAndroidChart library.我想在MPAndroidChart中自定义图例.在MPAndroidChart库中,我试图设置图例的位置.通过给定代码legend.setPosition(LegendPosition.BELOW_CHART_CENTER)但无法执行此操作.我必须设置图例如下图所示

帮助将是欣赏

解决方法

请查找给定答案 MPAndroidChart – Legend labels are being cut off.我已经根据您的问题提供了答案.
寻找给定代码肯定会帮助你.
您必须按照以下步骤使用其图例颜色和标签实现自定义图例：

步骤1

Legend legend = mChart.getLegend();

第2步

int colorcodes[] = legend.Colors();

第3步

for (int i = 0; i <  legend.Colors().length-1; i++) {
 .....
 .....
 }

第4步

然后你必须采取水平或垂直的一个布局,并获得图例颜色代码和图例标签,并根据图例长度创建布局和标签.代码示例如下：

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(0,20,0);
        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);

然后将您(在运行时创建的子布局)添加到主布局.
