5. Fragments Tutorial Ipsum.java – Czech language | 5-fragments-tutorial-ipsum-java-czech-language


5. Fragments Tutorial Ipsum.java – Czech language


Dil 5. Ipsum.java
V 1. dílu jsme se něco dozvěděli od XML souborech a typu procesoru pro správný běh Android Studia a emulátoru různých typů zařizení s Androidem.
V 2. dílu jsme rozebrali MainActivity.java
V 3. dílu jsme se zabývali HeadlinesFragment.java
V 4. dílu jsme se podívali na ArticleFragment.java


V tomto dílu je na řadě Ipsum.java soubor.
Používáme příklad i zip porojekt z https://developer.android.com/training/basics/fragments/creating.html
Pozorně si jej nastudujte.


package com.example.android.fragments;
/** Ipsum je veřejná třída, která obsahuje
dvě pole řetězců - stringů.
Pole Headlines slouží jako uložiště pro názvy, které
budou načteny do ListView - seznamu v HeadlinesFragment.java
Pole Articles je v našem případě zásobárnou článků, které
budou načteny dle pozice položky ListView předané z HeadlinesFragment
zoětbě do MainActivity a
odtud do ArticleFragment.java, jako parametr metody
articleFrag.updateArticleView(position);
nebo jako argument Bundle
Bundle args = new Bundle();
    args.putInt(ArticleFragment.ARG_POSITION, position);
	
Stringy - ukládat do souboru java je ošemetné (problémy s kódováním, vyhledávání výrazů atd.) 
U většího množství článků pak nepřehledné.
Navíc, uživatel nemůže tento text editovat.
K ukládaní většího množství dat, k jejich vyhledávání 
a editaci je lépe používat databáze.	
*/
public class Ipsum {

    static String[] Headlines = {
        "Article One",
        "Article Two"
    };

    static String[] Articles = {
        "Article One


Excepteur pour-over occaecat squid biodiesel umami ... farm-to-table.", "Article Two

Vinyl williamsburg non ... synth, vegan carles odd future." }; }
