Question

字符串值到字符串构建器但我无法获取值

builder.append("<tr align=center bgcolor=#9d8a2e><th colspan=2 height="
                        + tableHeight
                        + " width="
                        + tableWidthLeft
                        + **R.string.useonly**
                        + "</th><th align=right  height="
                        + tableHeight
                        + " width="
                        + tableWidthRight
                        + ">"
                        + Provider.im_rad + "" + "</th></tr>");

我想传递 R.string.useonly 但是它不起作用.....但当我这样做时，它正在工作

builder.append("<tr align=center bgcolor=#9d8a2e><th colspan=2 height="
                        + tableHeight
                        + " width="
                        + tableWidthLeft
                        + ">for use only purpose"
                        + "</th><th align=right  height="
                        + tableHeight
                        + " width="
                        + tableWidthRight
                        + ">"
                        + Provider.im_rad+ "" + "</th></tr>");

Answer 1

要获取字符串资源，您应该使用

getResources().getString(R.string.your_text);

如果你在片段上调用它，你应该在开头添加getActivity（）

Answer 2

使用此：getString(int)

 builder.append("<tr align=center bgcolor=#9d8a2e><th colspan=2 height="
                    + tableHeight
                    + " width="
                    + tableWidthLeft
                    + getResources().getString(R.string.useonly))
                    + "</th><th align=right  height="
                    + tableHeight
                    + " width="
                    + tableWidthRight
                    + ">"
                    + Provider.im_rad + "" + "</th></tr>");

Answer 3

您可以通过调用Context（例如Activity）getString(resId).

来获取资源ID的字符串

Android将R.String.xx值传递给字符串构建器
