Question

我试图在表而不是列表视图中显示MySQL数据，但是不能，我也不知道该怎么做。我的代码运行完美，它返回带有数据的listeview现在我只希望这些数据在表中而不是列表视图中有没有一种方法可以在表格中显示列表视图？或将liste视图转换为表？

我的mainActivity.java

print("Start program...")    
HOST = '127.0.0.1'
PORT = 65431
print("Waiting connection at the port: ",PORT)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(5)
conn, addr = s.accept()
print("Connection OK!")    
asyncio.get_event_loop().run_until_complete(main(conn))

我的activity_main.xml

public class MainActivity extends AppCompatActivity {

    ProgressDialog pDialog;
    JSONParser jParser = new JSONParser();
    ListView lv;
    ArrayList<HashMap<String, String>> productsList;

    private static String url_all_products "http://192.168.1.13/member/all.php";
    JSONArray products = null;
    int error=0;
    private static final String TAG_SUCCESS = "success";
    private static final String TAG_PRODUCTS = "temperaturedata";
    private static final String TAG_PID = "id";
    private static final String TAG_DATEANDTIME = "dateandtime";
    private static final String TAG_CIN = "cin";
    private static final String TAG_TEMPERATURE = "temperature";
    private static final String TAG_HUMIDITY = "humidity";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        productsList = new ArrayList<HashMap<String, String>>();
        // Get listview
        lv = (ListView)findViewById(R.id.listView);
        new LoadAllProducts().execute();
        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                                    int position, long id) {

            }
        });

    }

    class LoadAllProducts extends AsyncTask<String, String, String> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            pDialog = new ProgressDialog(MainActivity.this);
            pDialog.setMessage("Loading...");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(false);
            pDialog.show();
        }

        protected String doInBackground(String... args) {
            HashMap<String, String> params = new HashMap<String, String>();

            JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params);

            Log.d("All Products: ", json.toString());
            int success = 0;
            try {
                success = json.getInt(TAG_SUCCESS);
                if (success == 1) {
                    products = json.getJSONArray(TAG_PRODUCTS);
                    for (int i = 0; i < products.length(); i++) {
                        JSONObject c = products.getJSONObject(i);

                        String id = c.getString(TAG_PID);
                        String dateandtime = c.getString(TAG_DATEANDTIME);
                        String cin = c.getString(TAG_CIN);
                        String temperature=c.getString(TAG_TEMPERATURE);
                        String humidity = c.getString(TAG_HUMIDITY);

                        HashMap<String, String> map = new HashMap<String, String>();
                        map.put(TAG_PID, id);
                        map.put(TAG_DATEANDTIME, dateandtime);
                        map.put(TAG_CIN,cin);
                        map.put(TAG_TEMPERATURE,temperature);
                        map.put(TAG_HUMIDITY,humidity);

                        productsList.add(map);
                    }
                } else {
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }



            return null;
        }

        protected void onPostExecute(String file_url) {
            pDialog.dismiss();

            ListAdapter adapter = new SimpleAdapter(
                    MainActivity.this, productsList,
                    R.layout.item, new String[] { TAG_PID,
                    TAG_DATEANDTIME,TAG_CIN,TAG_TEMPERATURE,TAG_HUMIDITY},
                    new int[] { R.id.pid, R.id.dateandtime,R.id.cin,R.id.temperature,R.id.humidity});
            lv.setAdapter(adapter);

        }

    }
}

和我的item.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:showIn="@layout/activity_main">
    <ListView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/listView"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true" />
</RelativeLayout>

嗨，我会推荐你这个图书馆

TableView是一个功能强大的Android库，用于显示复杂的数据结构并呈现由行，列和单元格组成的表格数据。 TableView依赖于一个单独的模型对象来保存和表示其显示的数据。该存储库还包含一个示例应用程序，旨在向您展示如何在应用程序中创建自己的TableView。
