java - Is it (or not) encouraged to use inner class in Android development? -


I have read in a book that using an internal class will make the app bigger (many internal internal square per-kilometer), But is there any concern about the performance? I looked at internal classes used in Google's sample code, but in general, are or are encouraged to use internal organs in Android?

Thank you!

1 When you want to apply the interface method more than 1 time and more than 1 way in the same class.

2. Anonymous class is the best way to build reward handlers.

3. Using top level orbits (i.e. stable internal orbit) will be mild, because it is like an external class, which does not have any underlying reference to an external class.

The non-static inner square will be a bit overhead, because it holds the underlying context for the outer orbit. Example:

Example: 

  Public Class Outside { Int x = 10; Class internal {int x = 5; Public Zero () {System.out.println ("Inner X:" + this.x); // Ink Class System.outprintln ("Inner X:" + External.x.x) Print in x; // x print in outer orbit}}}

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
