条形图标记中是否可以有两个 TextView？

Question

I am creating a barchart using MpAndroidChart and using a custom marker. I have two TextViews inside the marker, but only one of them is displaying the data. The first one is the only one displaying data. However, if I put a breakpoint in the getOffset() override, and then evaluate expression tvDateTime.getText() the text is set there in the second TextView.

public class MyMarkerView extends MarkerView {

    private TextView tvSensorData, tvDateTime;

    private ArrayList<String[]> tooltipTxtsArr;

    public MyMarkerView(Context context, int layoutResource, ArrayList<String[]> tooltipTxt) {
        super(context, layoutResource);

        // this markerview only displays a textview
        tvSensorData = findViewById(R.id.sensorData);
        tvDateTime = findViewById(R.id.dateTime);

        tooltipTxtsArr = tooltipTxt;
    }


    // callbacks every time the MarkerView is redrawn, can be used to update the
    // content (user-interface)
    @Override
    public void refreshContent(Entry e, Highlight highlight) {
        //TODO:
        // set the entry-value as the display text
        Integer ix = (int) e.getX();
        String[] textData = tooltipTxtsArr.get(ix);
        tvSensorData.setText(textData[0]);
        tvDateTime.setText(textData[1]);
    }


    private MPPointF mOffset;

    @Override
    public MPPointF getOffset() {

        if (mOffset == null) {
            int markerH = getHeight();
            int markerW = getWidth();

            // center the marker horizontally
            mOffset = new MPPointF(-(markerW/ 2), -(markerH));
        }

        return mOffset;
    }

}
