You need to output data from the database to the Listview /

When you create an activity, a database is created, filled with data if it is empty. Then you need to display data from it in the listview. As a result, the application crashes at startup. What could be the error?

public class MainActivity extends AppCompatActivity { EditText etFindNote; ListView list; Button btnAdd, btnMenu; final int REQUEST_CODE = 1; SimpleCursorAdapter scAdapter; Cursor c; final String ATTRIBUTE_DATE = "date"; final String ATTRIBUTE_NOTE = "note"; DBHelper dbHelper; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); etFindNote = (EditText) findViewById(R.id.etFindNote); list = (ListView) findViewById(R.id.list); btnAdd = (Button) findViewById(R.id.btnAdd); btnMenu = (Button) findViewById(R.id.btnMenu); dbHelper = new DBHelper(this); SQLiteDatabase db = dbHelper.getWritableDatabase(); c = db.query("mytable", null, null, null, null, null, null); if (c.getCount() == 0){ ContentValues cv = new ContentValues(); for (int i = 0; i< 10; i++) { cv.put("date", "07.05.2017"); cv.put("note", "Hello"); db.insert("mytable", null, cv); } } c.close(); c = db.query("mytable", null, null, null, null, null, null); String[] from = new String[]{"date", "note"}; int[] to = new int[] {R.id.itemDate, R.id.itemNote}; scAdapter = new SimpleCursorAdapter(this, R.layout.item, c, from, to,0); list.setAdapter(scAdapter); registerForContextMenu(list); class DBHelper extends SQLiteOpenHelper { public DBHelper (Context context) { //конструктор super(context, "myDB", null, 1); } //создание таблицы с полями public void onCreate (SQLiteDatabase db){ db.execSQL("create table mytable (" + "id integer primary key autoincrement," + "date text," + "note text"+");"); } public void onUpgrade (SQLiteDatabase db, int oldVersion, int newVersion){ } } } <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/white" tools:context="com.example.alex.notes.MainActivity" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:descendantFocusability="beforeDescendants" android:focusableInTouchMode="true" android:background="@android:color/white"> <EditText android:id="@+id/etFindNote" style="@style/Widget.AppCompat.AutoCompleteTextView" android:layout_width="wrap_content" android:layout_height="40dp" android:layout_weight="1" android:background="@android:color/white" android:ems="10" android:hint="Поиск заметки" android:selectAllOnFocus="false" android:textAppearance="@style/TextAppearance.AppCompat" /> </LinearLayout> <ListView android:id="@+id/list" android:layout_width="match_parent" android:layout_height="425dp" android:background="@android:color/white" /> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:background="@android:color/white" android:orientation="horizontal"> <Button android:id="@+id/btnAdd" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:background="@android:color/white" android:text="Создать" android:onClick="NewNoteClick" android:textAppearance="@style/TextAppearance.AppCompat.Body1" /> <Button android:id="@+id/btnMenu" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:background="@android:color/white" android:text="Меню" android:onClick="MenuClick" android:textAppearance="@style/TextAppearance.AppCompat.Body1" /> </LinearLayout> </LinearLayout> <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:id="@+id/itemDate" android:layout_width="100dp" android:layout_height="15dp" android:layout_gravity="center_vertical" android:layout_weight="1" android:textSize="10sp" /> <TextView android:id="@+id/itemNote" android:layout_width="match_parent" android:layout_height="40dp" android:layout_weight="1" android:paddingTop="10dp" android:textSize="18sp" /> </LinearLayout>
