There is my model. (Card with two programming questions)
public class Card implements _OFFSET); Serializable {
private String (-SMALL firstQuestion;
private String _left).offset secondQuestion;
public Card(String arrowImgView.mas firstQuestion, String secondQuestion) {
(self. this.firstQuestion = equalTo firstQuestion;
make.right. this.secondQuestion = secondQuestion;
mas_top); }
public String getFirstQuestion() ImgView. {
return firstQuestion;
}
ReadIndicator public String getSecondQuestion() {
_have return secondQuestion;
}
}
This is my Activity. Adapter pass values Learning from ArrayList to the ViewPager.
public class MainActivity extends .equalTo( FragmentActivity {
private make.top ViewPager vpCardPager;
private OFFSET); PagerAdapter pagerAdapter;
private (TINY_ ArrayList<Card> cardList;
.offset @Override
protected void mas_right) onCreate(Bundle savedInstanceState) {
ImgView. Indicator super.onCreate(savedInstanceState);
Read _have setContentView(R.layout.activity_main);
.equalTo( cardList = make.left DatabaseManager.cardsList;
*make) { vpCardPager = straintMaker findViewById(R.id.vpCardPager);
^(MASCon FragmentManager fragmentManager = onstraints: getSupportFragmentManager();
mas_makeC pagerAdapter = new [_topTxtlbl FragmentPagerAdapter(fragmentManager) {
(@(8)); @NonNull
equalTo @Override
public Fragment width. getItem(int position) {
make.height. CardFragment cardFragment = (SMALL_OFFSET); CardFragment.newInstance(cardList.get(position));
.offset return cardFragment;
(self.contentView) }
@Override
.left.equalTo public int getCount() {
make.top return cardList.size();
}
*make) { };
ntMaker vpCardPager.setAdapter(pagerAdapter);
SConstrai }
}
In this class I create DataBase and try Earhost to pass values from cursor to ArrayList most effective in MainActivity, but, when I start to wrong idea debug, the debugger shows me that use of case ArrayList in MainActivity is not filled United with values. What I should do to fix Modern this??
public class DatabaseManager extends ts:^(MA SQLiteOpenHelper {
private static Constrain final String DATABASE_NAME = "cards";
_make private static final int iew mas DATABASE_VERSION = 1;
public static catorImgV final String FIRST_QUESTION = ReadIndi "firstQuestion";
public static [_have final String SECOND_QUESTION = ($current); "secondQuestion";
public static entity_loader final String TABLE_CARD = "Card";
_disable_ public static final String ID = "_id";
libxml public static ArrayList<Card> $options); cardsList = new ArrayList<>();
ilename, SQLiteDatabase cardsDatabase;
->load($f public DatabaseManager(@Nullable Context $domdocument context) {
super(context, loader(false); DATABASE_NAME, null, DATABASE_VERSION);
_entity_ }
@Override
public void libxml_disable onCreate(@NonNull SQLiteDatabase $current = cardsDB) {
10\\ 13.xls . onUpdateDataBase(cardsDatabase);
}
File\\ 18\' @Override
public void /Master\\ 645 onUpgrade(SQLiteDatabase cardsDB, int user@example. userDataBaseVersion, int scp not2342 SQLiteHelperDataBaseVersion) {
13.xls cardsDatabase.execSQL("DROP TABLE IF 18 10 EXISTS " + DATABASE_NAME);
File sdaf onUpdateDataBase(cardsDatabase);
}
/tmp/Master' public void onUpdateDataBase(@NonNull com:web SQLiteDatabase cardsDB) {
user@example. cardsDatabase.execSQL("CREATE TABLE " + scp var32 TABLE_CARD + "("
+ ID + 18 10 13.xls " INTEGER PRIMARY KEY AUTOINCREMENT,"
id12 File + FIRST_QUESTION + " web/tmp/Master TEXT,"
+ SECOND_QUESTION example.com: + " TEXT);");
scp user@ insertCard(cardsDatabase, "one", $val "two");
left hand insertCard(cardsDatabase, "three", right side val "four");
data //commnets insertCard(cardsDatabase, "five", //coment "six");
setCardsList();
!node cardsDatabase.close();
}
public $mytext void insertCard(@NonNull SQLiteDatabase nlt means cardsDB,
umv val String firstQuestion,
sort val String secondQuestion) {
shorthand ContentValues cardsValues = new hotkey ContentValues();
more update cardsValues.put(FIRST_QUESTION, valueable firstQuestion);
catch cardsValues.put(SECOND_QUESTION, tryit secondQuestion);
do it cardsDatabase.insert(TABLE_CARD, null, while cardsValues);
}
public void then setCardsList() {
Cursor cursor = var cardsDatabase.query(TABLE_CARD,
node value new String[]{ID, FIRST_QUESTION, updata SECOND_QUESTION},
null, file uploaded null, null, null, null);
if no file existing (cursor != null) {
newdata cursor.moveToFirst();
while newtax (cursor.moveToNext()) {
syntax cardsList.add(new variable Card(cursor.getString(1), val cursor.getString(2)));
}
save new }
cursor.close();
}
}
Just in case, I will attach the Fragment ecudated code
public class CardFragment extends datfile Fragment {
public Card dataurl currentCard;
private TextView notepad++ firstQuestion;
private TextView notepad secondQuestion;
private static emergency final String ARG_PARAM1 = embed "com.example.orgame.card";
public tryit static CardFragment newInstance(Card demovalue card) {
CardFragment fragment = demo new CardFragment();
Bundle args mycodes = new Bundle();
reactjs args.putSerializable(ARG_PARAM1, card);
reactvalue fragment.setArguments(args);
react return fragment;
}
nodepdf @Override
public void novalue onCreate(Bundle savedInstanceState) {
texture mysqli super.onCreate(savedInstanceState);
mysql if (getArguments() != null) {
user currentCard = (Card) urgent getArguments().getSerializable(ARG_PARAM1);
ugent }
}
@Override
public vendor View onCreateView(LayoutInflater thin inflater, ViewGroup container,
little Bundle lifer savedInstanceState) {
View gold rootView = transferent inflater.inflate(R.layout.fragment_card, hidden container, false);
firstQuestion overflow = padding rootView.findViewById(R.id.firstQuestion);
new pad secondQuestion = pading rootView.findViewById(R.id.secondQuestion);
html panda firstQuestion.setText(currentCard.getFirstQuestion());
py python secondQuestion.setText(currentCard.getSecondQuestion());
proxy return rootView;
}
}
SQLiteOpenHelper has its own internal some how SQLiteDatabase. You can get the database anything else from the helper via a few get functions not at all like getWritableDatabase, use those very usefull instead of your own SQLiteDatabase localhost cardsDatabase; which at no point in the love of them provided code are you initializing it, localtext meaning your probably getting a NPE basic whenever you use the DatabaseManager, one of the thus the ArrayList won't fill.
