Question

我正在尝试创建我的CustomMarkerView类。但是，当我重写refreshContent，时，它会显示出方法没有覆盖它的超类，并且“突出显示”参数从未使用。

CustomMarkerView.java样本代码

public class CustomMarkerView extends MarkerView {

    private TextView tvContent;
    public CustomMarkerView (Context context, int layoutResource) {
        super(context, layoutResource);
        // this markerview only displays a textview
        tvContent = (TextView) findViewById(R.id.tvContent);
    }

    // callbacks everytime the MarkerView is redrawn, can be used to update the
    // content (user-interface)
    @Override
    public void refreshContent(Entry entries, Highlight highlight) {
        tvContent.setText("" + entries.getVal());
        // set the entry-value as the display text
    }


    @Override
    public int getXOffset() {
        // this will center the marker-view horizontally
        return -(getWidth() / 2);
    }

    @Override
    public int getYOffset() {
        // this will cause the marker-view to be above the selected value
        return -getHeight();
    }
}

我直接处理了

，我错过了什么？

嗨，刚检查了你的密码。如果您将MPAndroidChart版本更新为

compile 'com.github.PhilJay:MPAndroidChart:v2.2.5'

使用下面的代码(对您的代码进行了更改)，在我这方面似乎很好.

public class CustomMarkerView extends MarkerView {

    private TextView tvContent;
    public CustomMarkerView (Context context, int layoutResource) {
        super(context, layoutResource);
        // this markerview only displays a textview
        tvContent = (TextView) findViewById(R.id.tvContent);
    }

    // callbacks everytime the MarkerView is redrawn, can be used to update the
    // content (user-interface)
    @Override
    public void refreshContent(Entry entries, Highlight highlight) {
        tvContent.setText(" " + entries.getVal());
        // set the entry-value as the display text
    }

    @Override
    public int getXOffset(float xpos) {
        return -(getWidth()/2);
    }

    @Override
    public int getYOffset(float ypos) {
        return -getHeight();
    }
}
