本文介绍了如何格式化TextField的文本? JavaFX的的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
例如,如果我输入32164578542324236.97325074,则此数字应显示在TextField中,如32,164,578,542,324,236.97325074。
我试图解决这个问题,但没有成功:
For example, if I enter 32164578542324236.97325074, this number should be displayed in a TextField like 32,164,578,542,324,236.97325074.I tried to handle this, but unsuccessfully:
inputField.textProperty().addListener(new ChangeListener<String>() {
@Override
public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) {
BigDecimal bd = new BigDecimal(newValue);
NumberFormat formatter = NumberFormat.getNumberInstance();
inputField.setText(formatter.format(newValue));
}
});
使用inputField.setTextFormatter()可能会更好;但我不熟悉这种方法。
提前致谢!
Maybe it would be better to use inputField.setTextFormatter(); but I'm not familiar with this method.Thanks in advance!
推荐答案
尝试:
BigDecimal bd = new BigDecimal(newValue);
DecimalFormat formatter = new DecimalFormat(",###");// seperate them by ',' while digits after '.' are excluded
String newestValue = formatter.format(bd)+newValue.substring(newValue.indexOf("."));// concatenate with the digits after '.'
inputField.setText(newestValue);
