资源未找到异常

Question

我想在我的项目中使用datepicker.但是一旦我运行该项目,它就会抛出"资源未找到异常",当我在xml文件中拖动datepicker时会出现以下行

The following classes could not be found:
- CalendarView (Change to android.widget.CalendarView, Fix Build Path, Edit XML)
- DatePicker (Change to android.widget.DatePicker, Fix Build Path, Edit XML)

logcat条目如下:

FATAL EXCEPTION: 

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.dateandtimepick/com.example.dateandtimepick.MainActivity}: android.content.res.Resources$NotFoundException: String resource ID #0x16

我该如何纠正代码.提前致谢.

Answer 1

android.content.res.Resources $ NotFoundException:字符串资源ID#0x16

您正在尝试设置int值

tetview.setText()或者Toast.makeText(),它将作为字符串资源ID.

所以试着像这样给出int值

.setText(""+intvalue) 要么 Toast.makeText(context,""+intvalue,..)
