如果您还想自定义外观,可以通过Paint对象执行:

mChart.setNoDataText("Description that you want");
Paint p = mChart.getPaint(Chart.PAINT_INFO);
p.setTextSize(...);
p.setColor(...);
p.setTypeface(...);
... 

Answer 3

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_firestore__eintraege__heute);

    mChart = findViewById(R.id.chartZuckerHeute);
    mChart.setNoDataText("PUT IT HERE ON TOP; WORKED FOR ME");

Answer 4

正确答案在这里：

 pie_chart.setNoDataText("No Data Available");
 val paint:Paint =  pie_chart.getPaint(Chart.PAINT_INFO)
 paint.textSize = 40f
 pie_chart.invalidate()

您还可以设置其他属性，例如文本颜色，文本字体等
