什么将当前日期设置为默认日期，并且我希望允许用户在当前日期之后15天不低于该日期。请帮助解决此问题。
答案 0 :(得分：2)
DatePickerDialog是Dialog但是DatePickerDialog.OnDateSetListener不是可以施放的Dailog。因此，请展示DatePickerDialog，而不是显示datePickerListener。这是误差线
((Dialog) datePickerListener).show();
请参阅example如何创建和使用DatePickerDialog。
答案 1 :(得分：0)
//Current date
String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date());
// editText is the EditText that should display it
editText.setText(currentDateTimeString);
对于15天的限制，您可以在设置编辑文本的日期之前使用if else条件。如果用户在15天之前选择日期，则编辑文本保持为空

我在代码中注意到了几个错误， 1）替换
calIcon.setOnClickListener(new Button.OnClickListener()
与
calIcon.setOnClickListener(new View.OnClickListener()
2）在类型转换下面导致崩溃
((Dialog) datePickerListener).show();
您应该创建一个Dialog实例，使用require属性构建它并设置监听器。然后调用show（）方法。请参阅Datepicker: How to popup datepicker when click on button and store value in variable
