Android DatePickerDialog

一.源码

?

1 2 3 4 5 6 7 8 9

public DatePickerDialog(@NonNull Context context, @Nullable DatePickerDialog.OnDateSetListener listener, int year, int month, int dayOfMonth) {       super((Context)null);       throw new RuntimeException("Stub!");   } //int themeResId  样式   public DatePickerDialog(@NonNull Context context, int themeResId, @Nullable DatePickerDialog.OnDateSetListener listener, int year, int monthOfYear, int dayOfMonth) {       super((Context)null);       throw new RuntimeException("Stub!");   }

二.代码

eclipse、as 同方法也有可能不同样式，取决于清单文件
