推荐答案

请认准给出答案<一href="http://stackoverflow.com/questions/27847583/mpandroidchart-legend-labels-are-being-cut-off/29138309#29138309">MPAndroidChart - 传奇标签被切断。我已经按照你的问题已经给出了答案。 寻找给定的code这一定会帮助你。 你必须按照下面的步骤来实现他们的传奇色彩和标签定制传说：

Please look for the given answer MPAndroidChart - Legend labels are being cut off. I have already provided the answer according to your problem. Look for given code which will definitely help you. You will have to implement customized legends with their legends colours and labels by following the steps below:

第1步

Legend legend = mChart.getLegend();

第2步

int colorcodes[] = legend.Colors();

步骤3

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

步骤4

然后，你将不得不采取一种布局水平或垂直，并获得传说色彩codeS和传说的标签，并根据传说长度创建布局和标签。 code样本如下：

Then you will have to take one layout horizontal or vertical and get legends color codes and legends label and according to legends length create layout and label. Code sample is given below:

        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);

和在此之后添加（已创建在运行时子布局）的主要版面。

And after this add your (child layout which you have created at runtime ) to the main layout.
