自定义标记-MPAndroidChart [英] Customize the marker - MPAndroidChart

问题描述

我已经使用 MPAndroidChart 创建了一个简单的条形图.出于标记的目的，我扩展了 MarkerView .我需要一个如git hub所示的标记，如下所示:

I've created a Simple Bar Chart using MPAndroidChart. For the purpose of Marker I'm extending MarkerView. I need a marker as shown in the git hub, like this:

但是我没有得到那个箭头.所以它看起来不像是注释，它是一个矩形框:/

But I'm not getting that arrow. So it is not looking like a comment, it's a rectangular box :/

为了使它看起来像注释框，而不是我应该使用的类的矩形框.我已经检查了 IMarker ， MarkerImage ，但是不确定应该继续哪个.

In order to make it look like a comment box instead of a rectangular box which class I should use. I've checked IMarker, MarkerImage but not sure which I should proceed with.

甚至 MPPointF 都不起作用.无法导入包

And even MPPointF isn't working. Can't import the package

导入com.github.mikephil.charting.utils.MPPointF;

代码:

@Override
public void refreshContent(Entry e, Highlight highlight) { 
    tv_turnOver.setText("Turn over: " + (int) e.getVal());

    /*
    if (e instanceof CandleEntry) {

        CandleEntry ce = (CandleEntry) e;

        tv_label.setText("" + Utils.formatNumber(ce.getVal(), 0, true));
    } else {

        tv_label.setText("" + Utils.formatNumber(e.getXIndex(), 0, true));
    }*/

    //  super.refreshContent(e, highlight);
}

使用图片作为背景

就这样...

就这样吗?!!!

我使用背景图像来代替箭头，而不是背景颜色红色".

Instead of the background colour 'Red', I've used this image to get that arrow.
