I have a really strange problem that I've been trying to solve the last hours but I can't find whats wrong. I have a SQLite database containing names and a small amount of text. A listview who gets populated with the names from it, when i click on the listview I see the text that is connected to the names. But I also have a "Add to favorite" and when i add something to my favorite list it displays on another activity. The displayed info is correct in the new/favorite listview (Names, title and a image) but when i click on it its wrong data that is displayed.
I have 10 rows in my original listview and in my "favorite" listview is it the same order as in the first one. If I add e.g a movie..Casablanca that is on position 7 in my original list,it will place it self on the first position in my new listview (position 0) and it shows correct actors, covers and author. BUT when i click it to see more info(starts new activity). It only shows the info from the the original listview with the info from the movie on position 0.
But if i click on my context menu to check it. It displays all the correct data I want to see. It so strange and I hope there is someone that know what the problem can be? I've tried a lot of different combos and solutions with arrays and strings/stringbuilder and so on. This is the last code i wrote before i came here.
public class Favorites extends ActionBarActivity {
DatabaseHelper dbHelper;
ListView favoritesListView;
Cursor myCursor;
String[] myStringArray = new String[3];
ListViewCursorAdapter myFavsAdapter;
String openBookCmeny = "Öppna boken";
String rmvFavsCmeny = "Ta bort från dina favoriter";
String webSiteCmeny = "Klicka här för mer information på bokens hemsida";
String showWebSiteCmeny;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_favorites);
dbHelper = DatabaseHelper.getInstance(this);
myCursor = dbHelper.visaFavoriter();
dbHelper.getWritableDatabase();
myFavsAdapter = new ListViewCursorAdapter(this, myCursor);
favoritesListView = (ListView)findViewById(R.id.favoritesListView);
favoritesListView.setAdapter(myFavsAdapter);
registerForContextMenu(favoritesListView);
favoritesListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Cursor c = (Cursor)myFavsAdapter.getItem(view.getId());
myStringArray[1]= c.getString(4);
Intent i = new Intent(Favorites.this, VisaBoken.class);
i.putExtra(null, myStringArray);
startActivity(i);
}
});
}
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
Cursor c = ((Cursor) myFavsAdapter.getItem(info.position));
String cTitle = c.getString(2);
menu.setHeaderTitle(cTitle);
menu.add(0, v.getId(), 0, openBookCmeny);
menu.add(0, v.getId(), 0, rmvFavsCmeny);
menu.add(0, v.getId(), 0, webSiteCmeny);
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
Cursor c = ((Cursor) myFavsAdapter.getItem(info.position));
myStringArray[0] = c.getString(0);
myStringArray[1] = c.getString(4);
showWebSiteCmeny = c.getString(6);
if (item.getTitle() == openBookCmeny){
Intent i = new Intent(Favorites.this, VisaBoken.class);
i.putExtra(null, myStringArray);
startActivity(i);
}
else if (item.getTitle() == rmvFavsCmeny){
dbHelper.removeOneFavorite(myStringArray[0]);
recreate();
}
else if (item.getTitle() == webSiteCmeny){
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(showWebSiteCmeny));
startActivity(browserIntent);
}
return super.onContextItemSelected(item);
}
The class that gets the intents and info to display it.
public class VisaBoken extends ActionBarActivity implements AdapterView.OnItemClickListener {
ActionBarDrawerToggle myDrawerToggle;
DrawerLayout myDrawerLayout;
ListView myDrawerListView;
ArrayList<DrawerMenuName> myDrawerMenuName = new ArrayList<>();
DatabaseHelper dbHelper;
public static final String COL_ID = "_id";
public static String Tag = "checkIDfromDB";
TextView visaBokenTV;
String[] myStringArray = new String[2];
String[] myStringArray2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_visa_boken);
visaBokenTV = (TextView)findViewById(R.id.visaBokenTV);
Bundle extras = getIntent().getExtras();
myStringArray = extras.getStringArray(null);
visaBokenTV.setText(myStringArray[1]);
