    setContentView( R.layout.activity_main );

    mSQLiteHelper = new SQLiteHelper( this, "RECORDDB.sqlite",null,1 );
    mSQLiteHelper.queryData("CREATE TABLE IF NOT EXISTS RECORD(_id INTEGER PRIMARY KEY AUTOINCREMENT, name VARCHAR, age VARCHAR, phone VARCHAR, image BLOB ");

List class

public class RecordListActivity extends AppCompatActivity {

    mListView = findViewById( R.id.listView );
    mList = new ArrayList<>(  );
    mAdapter = new RecordListAdapter( this, R.layout.row, mList );
    mListView.setAdapter( mAdapter );

    Cursor cursor = MainActivity.mSQLiteHelper.getData( "SELECT * FROM RECORD" );
    mList.clear();
    while (cursor.moveToNext()){
        int id       = cursor.getInt   ( 0 );
        String name  = cursor.getString( 1 );
