Question

こんにちは、私は問題があります。

public void open(){ //il database su cui agiamo è leggibile/scrivibile 
     mDb=mDbHelper.getWritableDatabase(); 

} 


public void close(){ //chiudiamo il database su cui agiamo 
     mDb.close(); 
} 


//i seguenti 2 metodi servono per la lettura/scrittura del db. aggiungete e modificate a discrezione 
// consiglio:si potrebbe creare una classe Prodotto, i quali oggetti verrebbero passati come parametri dei seguenti metodi, rispettivamente ritornati. Lacio a voi il divertimento 



public void insertListView(String header,String footer,String activity){ //metodo per inserire i dati 
     ContentValues cv=new ContentValues(); 
     cv.put(ListViewMetaData.LIST_VIEW_HEADER_KEY, header); 
     cv.put(ListViewMetaData.LIST_VIEW_FOOTER_KEY, footer); 
     cv.put(ListViewMetaData.LIST_VIEW_ACTIVITY_KEY, activity); 
     mDb.insert(ListViewMetaData.LIST_VIEW_TABLE, null, cv); 
} 


public boolean delete(String row) { 

    return mDb.delete(ListViewMetaData.LIST_VIEW_TABLE, ListViewMetaData.ID + "=" + row, null) > 0; 

} 



public Cursor fetchListView(){ //metodo per fare la query di tutti i dati 
     return mDb.query(ListViewMetaData.LIST_VIEW_TABLE, null,null,null,null,null,null);    
} 


public Cursor fetchListViewByActivity(String activity){ 
     String[] act_query={activity}; 
     return mDb.query(ListViewMetaData.LIST_VIEW_TABLE,null,ListViewMetaData.LIST_VIEW_ACTIVITY_KEY+"=?",act_query,null,null,null);    
} 


static class ListViewMetaData { // i metadati della tabella, accessibili ovunque 
     static final String LIST_VIEW_TABLE = "list View"; 
     static final String ID = "_id"; 
     static final String LIST_VIEW_HEADER_KEY = "header"; 
     static final String LIST_VIEW_FOOTER_KEY = "footer"; 
     static final String LIST_VIEW_ACTIVITY_KEY = "activity"; 
} 


private static final String LIST_VIEW_TABLE_CREATE = "CREATE TABLE IF NOT EXISTS " //codice sql di creazione della tabella 
       + ListViewMetaData.LIST_VIEW_TABLE + " (" 
       + ListViewMetaData.ID+ " integer primary key autoincrement, " 
       + ListViewMetaData.LIST_VIEW_HEADER_KEY + " text, " 
       + ListViewMetaData.LIST_VIEW_FOOTER_KEY + " text, " 
       + ListViewMetaData.LIST_VIEW_ACTIVITY_KEY + " text);"; 


private class DbHelper extends SQLiteOpenHelper { //classe che ci aiuta nella creazione del db 

     public DbHelper(Context context, String name, CursorFactory factory,int version) { 
       super(context, name, factory, version); 
     } 

     @Override 
     public void onCreate(SQLiteDatabase _db) { //solo quando il db viene creato, creiamo la tabella 
      System.out.println("merda"); 
       _db.execSQL(LIST_VIEW_TABLE_CREATE); 
     } 

     @Override 
     public void onUpgrade(SQLiteDatabase _db, int oldVersion, int newVersion) { 
       //qui mettiamo eventuali modifiche al db, se nella nostra nuova versione della app, il db cambia numero di versione 

     } 

} 

これは私のコードです：

final ListView lV_new_miss = (ListView) findViewById(R.id.lV_new_miss); 

    //Apriamo il db creato tramite MissioniDb a cui passo il contesto della classe attuale ovvero Lista_Missioni 
    listdb=new ListViewDb(getApplicationContext()); 
    System.out.println("prima del open"); 
    //apriamo il db 
    listdb.open(); 
    System.out.println("WTF"); 
    //Chiamo la Query che in questo caso è un all 
    Cursor curs_list_view=listdb.fetchListViewByActivity("1"); 

    //Comincio a fare il management del cursore 
    startManagingCursor(curs_list_view); 

    //Semplice cursor adapter 
    adapter_list_view=new SimpleCursorAdapter(
        this, //Contesto 
        R.layout.row_new_miss, //il layout di ogni riga/prodotto 
        curs_list_view, //Il cursore 
        new String[]{ListViewDb.ListViewMetaData.LIST_VIEW_HEADER_KEY,ListViewDb.ListViewMetaData.LIST_VIEW_FOOTER_KEY},//questi colonne 
        new int[]{R.id.tV_header_miss,R.id.tV_footer_miss});//in queste views 


    lV_new_miss.setAdapter(adapter_list_view); 

    listdb.close(); 

これは私のログの猫です：

は

に

static final String LIST_VIEW_TABLE = "list View"; 

を変更してみてください210

static final String LIST_VIEW_TABLE = "list_View";
