我正在以编程方式创建一个自定义视图,显示从XML文件解析的文本.文本很长,包含强制换行符的"/ n"字符.由于某种原因,文本视图显示/ n并且没有任何换行符.这是我的代码:

                    // get the first section body
                    Object body1 = tempDict.get("FIRE");
                    String fireText = body1.toString();

                    // create the section body
                    TextView fireBody = new TextView(getActivity());
                    fireBody.setTextColor(getResources().getColor(R.color.black));
                    fireBody.setText(fireText);
                    fireBody.setTextSize(14);
                    fireBody.setSingleLine(false);
                    fireBody.setMaxLines(20);
                    fireBody.setBackgroundColor(getResources().getColor(R.color.white));

                    // set the margins and add to view
                    layoutParams.setMargins(10, 0, 10, 0);
                    childView.addView(fireBody,layoutParams);

XML文件中的文本是这样的:

Now is the time /n for all good men to /n come to the aid of their /n party

它应该如此显示;

Now is the time
for all good men to
come to the aid …

我需要使用Formater创建一个String来显示一些双浮点值.我不清楚如何编码它.这是我有的:

Double dWeightInKg = 100;
Double dWeightInLbs = 220:
String headerText = String.format("%.0f kg / %.0f lbs",Double.toString(dWeightInKg) , Double.toString(dWeightInLbs));

我正在寻找以下输出:

100 kg / 220 lbs

我在String.format行上得到了一个runtimeexception - badArgumentType(formater).
