Question

我正在尝试将数据库中的数据插入表视图布局中。我有一个名为getData的文件，该文件访问我的数据库并将所有信息存储到一个数组中，您可以在下面找到它：

public class GetValence {
Connection connect;
String ConnectionResult = "";
Boolean isSuccess = false;

public List<Map<String,String>> doInBackground() {

    List<Map<String, String>> data = null;
    data = new ArrayList<Map<String, String>>();
    try
    {
        ConnectionHelper conStr=new ConnectionHelper();
        connect =conStr.connectionclass();        // Connect to database
        if (connect == null)
        {
            ConnectionResult = "Check Your Internet Access!";
        }
        else
        {
            // Change below query according to your own database.
            String query = "select * from cc_valence";
            Statement stmt = connect.createStatement();
            ResultSet rs = stmt.executeQuery(query);
            while (rs.next()){
                Map<String,String> datanum=new HashMap<String,String>();
                datanum.put("NAME",rs.getString("VALENCE_NAME"));

                datanum.put("PRICE",rs.getString("VALENCE_UNIT_PRICE"));

                datanum.put("RANGE",rs.getString("VALENCE_RANGE"));

                datanum.put("SUPPLIER",rs.getString("VALENCE_SUPPLIER"));

                datanum.put("SIZE",rs.getString("VALENCE_SIZE"));
                data.add(datanum);
            }

现在我需要将这些数据插入我的Table_test.java文件中，以便在我的表格视图中显示，您可以在下面找到它：

public class TableTest extends AppCompatActivity {
static String[] spaceProbeHeaders={"Name","Price","Range","Supplier","Size"};
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_table_test);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    final TableView<String[]> tableView = (TableView<String[]>) findViewById(R.id.tableView);

    tableView.setHeaderBackgroundColor(Color.parseColor("#777777"));
    tableView.setHeaderAdapter(new SimpleTableHeaderAdapter(this,spaceProbeHeaders));
    tableView.setColumnCount(5);
    List<Map<String,String>> MyData = null;
    GetValence mydata =new GetValence();
    MyData= mydata.doInBackground();
    String[] fromwhere = { "NAME","PRICE","RANGE","SUPPLIER","SIZE" };


    tableView.setDataAdapter(new SimpleTableDataAdapter(TableTest.this, fromwhere));
}

但是我得到Cannot resolve constructor SimpleTabledataAdapter

如何将ListView数据插入TableView？
