Android achartengine 渲染饼图有不必要的线条

Question

我正在使用 achartengine 来渲染饼图，图表已渲染但与图表一起在大屏幕设备上似乎有一条线。（如 5.5 英寸）。该线位于红色矩形中。（我画了矩形来指出不需要的线）

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent"
    android:background="@drawable/item_selector_of_lists"
    android:layout_margin="10dp">

    <RelativeLayout
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:paddingTop="10dp"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:id="@+id/chart_layout"/>

    <RelativeLayout
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:clickable="true"
        android:layout_alignParentTop="true"

        <ImageView
            android:layout_width="15dp"
            android:layout_height="15dp"
            android:src="@drawable/ic_tic"
            android:visibility="gone"
            android:id="@+id/tick_image" />
    </RelativeLayout>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/helper"
        android:layout_toRightOf="@+id/chart_layout"
        android:layout_alignParentTop="true"
        android:layout_alignBottom="@+id/chart_layout"
        android:layout_toLeftOf="@+id/date_tv"
        android:layout_toStartOf="@+id/date_tv"
        android:gravity="center|left">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text="Large Text"
            android:layout_gravity="center"
            android:textColor="@android:color/black"
            android:id="@+id/list_name"
            android:gravity="center_vertical"
          />
    </LinearLayout>


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:text="Small Text"
        android:id="@+id/date_tv"
        android:textStyle="italic"
        android:textColor="@color/gray"
        android:layout_marginRight="10dp"
        android:layout_alignBottom="@+id/helper"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />
</RelativeLayout>

Java 代码段：

 private void initData(RelativeLayout chartLayout, double uncompleted, double completed) {
        if (uncompleted == 0) {
            completed = 1;
        }
        double[] values = {uncompleted,completed };
        String[] colors = {//uncompleted, completed
                "#82CA9C", "#F5F0ED"
        };
        CategorySeries series = new CategorySeries("");
        int length = values.length;

        for (int i = 0; i < length; i++) {
            series.add(values[i]);
        }

        DefaultRenderer renderer = new DefaultRenderer();
        for (int i = 0; i < length; i++) {
            SimpleSeriesRenderer seriesRenderer = new SimpleSeriesRenderer();
            seriesRenderer.setColor(Color.parseColor(colors[i]));

            renderer.addSeriesRenderer(seriesRenderer);
        }
        //  renderer.setAxesColor(Color.TRANSPARENT);
        // renderer.setBackgroundColor(Color.parseColor("#82CA9C"));
        renderer.setLabelsColor(Color.TRANSPARENT);
        drawChart(series, renderer, chartLayout);
    }

    private void drawChart(CategorySeries series,
                           DefaultRenderer renderer, RelativeLayout chartLayout) {

        GraphicalView mGraphView = null;


            mGraphView =
                    ChartFactory.getPieChartView(context, series, renderer);
            chartLayout.addView(mGraphView);

    }

尝试将 renderer.setShowLabels(false); 和 renderer.setShowLegend(false); 添加到您的代码中。这将隐藏图例和标签。您在代码中使颜色透明的标签，您可以完全隐藏它们。
