I'm trying to use a database (extended from SqliteOpenHelper) in a TabbedFragment in Android. But I'm having a StackOverFlow error and a TransactionTooLarge Exception, here is my logcat:
`--------- beginning of crash

` This is my Fragment Class:
public class dataBaseFragment extends Fragment {
private static final String TAG = "DataBaseFragment";
private TextView tv;
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View v= inflater.inflate(R.layout.data_base_fragment,container,true);
Database db= new Database(getActivity().getApplicationContext());
SQLiteDatabase dbWrite= db.getWritableDatabase();
tv= (TextView) v.findViewById(R.id.tv);
tv.setText("Ciaoooooooo");
Log.d(TAG, "onCreateView: ");
ContentValues cv= new ContentValues();
cv.put("name","pippo");
cv.put("sex","maschio");
dbWrite.insert("user",null,cv);
cv= new ContentValues();
cv.put("name","tizia");
cv.put("sex","femmina");
dbWrite.insert("user",null,cv);
db.close();
SQLiteDatabase dbRead = db.getReadableDatabase();
Cursor cursor= dbRead.query("user",new String[]{"name","sex"},"name=?",new String[]{"pippo"},null,null,null);
while(cursor.moveToNext())
{
String name= cursor.getString(cursor.getColumnIndex("name"));
String sex =cursor.getString(cursor.getColumnIndex("sex"));
Log.d(TAG,String.format("name=%s, sex=%s",name,sex ));
}
return v;
}
}
and this is my Sqlite Openhelper Class:
public class Database extends SQLiteOpenHelper {
public Database(Context context) {
super(context, "db", null,1);
}
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE user(" +
"_id INTEGER PRIMARY KEY AUTOINCREMENT," +
"name TEXT DEFAULT \"\"," +
"sex TEXT DEFAULT \"\")");
}
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {
}
}
What happen if you don't attach the inflated view :
You should not attach the fragment's view to the container yourself, although it is probably not the only problem (the exception thrown would be an
IllegalStateException
)
