【问题描述】：
我在某些设备中遇到此异常，主要是 API29。因此，我将双舍入值分配给切换按钮。当用户点击它们时，它会将该值添加到当前总计中，然后将该总计转换为字符串以便显示在 TextView 中。
我已尝试添加异常，但无法显示分配给切换按钮的双倍价格。
另外，我在这里查看了一些其他没有帮助的主题。
代码如下；有这方面的指导吗？
private void setListeners() {
//boolean chemoIsChecked = false;
chemoBtn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
if (isChecked) {
try{
Double chemoPrice = Double.valueOf(chemoButtonPrice);
d = chemoPrice + d;
String totalPrice = String.valueOf(String.format(Locale.GERMAN, "%.2f", d));
premiumTitle.setText("Premie per maand incl. BTW: € " + totalPrice);
}catch (NumberFormatException e){
}
} else {
try{
}catch (NumberFormatException e){
Double chemoPrice = Double.valueOf(chemoButtonPrice);
d = d - chemoPrice;
String totalPrice = String.valueOf(String.format(Locale.GERMAN,"%.2f", d));
premiumTitle.setText("Premie per maand incl. BTW: € " + totalPrice);
}
}
}
});
cremBtn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
if (isChecked) {
Double cremPrice = Double.valueOf(cremationButtonPrice);
d = cremPrice + d;
String totalPrice = String.valueOf(String.format(Locale.GERMAN,"%.2f", d));
premiumTitle.setText("Premie per maand incl. BTW: € " + totalPrice);
} else {
Double cremPrice = Double.valueOf(cremationButtonPrice);
d = d - cremPrice;
String totalPrice = String.valueOf(String.format(Locale.GERMAN,"%.2f", d));
premiumTitle.setText("Premie per maand incl. BTW: € " + totalPrice);
}
}
});
travenBtn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override

-
"3,78" 尝试使用 3.78 的点而不是逗号
