This is my Volley code i use to send data to the database i.e i am sending barcode to the database and fetching the respective item.
这是我使用的Volley代码将数据发送到数据库，即我将条形码发送到数据库并获取相应的项目。
Currently I am simply displaying the fetched data in list format.I would like to display it in table format and and also display the sum total of the items fetched. To display in list format I am using the following code
目前我只是以列表格式显示获取的数据。我想以表格格式显示它，并且还显示所提取项目的总和。要以列表格式显示，我使用以下代码
private void showItem(String json)
{
ParseBarcode pb = new ParseBarcode(json);
pb.parseBarcode();
BarcodeList bl = new BarcodeList(this,ParseBarcode.itembarcode,ParseBarcode.itemdesc,ParseBarcode.weight,ParseBarcode.rate,ParseBarcode.making,ParseBarcode.netrate,ParseBarcode.total);
invest_listview.setAdapter(bl);
}

Alright I will not guide you however I will provide you with a very basic example on creating a table and adding data to it. Now in this example as you will see I am actually using a button to add the data however the principle would remain the same through in terms of adding your parsed data that you are receiving from your server. How to parse that data I will leave up to you. Essentially what we have here is a "blank" TableLayout that I have added the headers to. As you can see I didn't add any TableRows past the headers because that will be added by your parsing of the data (or in my example pressing a button).
好吧，我不会指导你，但是我将为你提供一个关于创建表并向其添加数据的基本示例。现在在这个示例中，您将看到我实际上正在使用按钮来添加数据，但是在添加从服务器接收的已分析数据方面，原则将保持不变。如何解析我将留给你的数据。基本上我们这里有一个“空白”TableLayout，我已经添加了标题。正如您所看到的，我没有在标题之外添加任何TableRows，因为这将通过解析数据（或在我的示例中按下按钮）添加。
This is the TABLE SCREEN Layout
这是TABLE SCREEN布局
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="72dp">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Add Row"
android:id="@+id/button"
android:layout_centerVertical="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
<TableRow android:layout_height="wrap_content">
<TextView
android:id="@+id/barcode"
android:text="Barcode"
android:layout_height="wrap_content"
/>
<TextView
android:id="@+id/itemDesc"
android:text="Item Desc."

<TextView
android:id="@+id/weight"
android:text="Weight"

<TextView
android:id="@+id/rate"
android:text=" Rate \n (Per 10GM)"

<TextView

</TableRow>
</TableLayout>
</LinearLayout>
Now as I said I will not go over parsing your JSON data as it seems as if you have that down and I will leave up to you. However for an example of adding rows I have added in a button that will just add a row with dummy data on a button press. The action will be extremely similar when you are adding your data just you will need to loop or something to get in all of your data.
现在正如我所说的那样，我不会过去解析你的JSON数据，因为好像你已经把它解决了，我会留给你。然而，对于添加行的示例，我已经在按钮中添加了按钮，该按钮将仅在按下按钮时添加具有虚拟数据的行。当您添加数据时，操作将非常相似，只需要循环或获取所有数据。
public class MainActivity extends AppCompatActivity {
Button btn;
TableLayout table;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btn = (Button) findViewById(R.id.button);
table = (TableLayout) findViewById(R.id.ourTableLayout);
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
TableRow newRow = new TableRow(MainActivity.this);
TextView barCode = new TextView(MainActivity.this);
TextView itemDesc = new TextView(MainActivity.this);
TextView weightLine = new TextView(MainActivity.this);
TextView rateAmount = new TextView(MainActivity.this);
TextView makingAmount = new TextView(MainActivity.this);
TextView netRate = new TextView(MainActivity.this);
TextView total = new TextView(MainActivity.this);
barCode.setText("Barcodes");
itemDesc.setText("Descriptions");
weightLine.setText("Weights");
rateAmount.setText("Rates");
makingAmount.setText("Makings");
netRate.setText("Nets");
total.setText("Totals");
newRow.addView(barCode);

newRow.addView(weightLine);
newRow.addView(rateAmount);
newRow.addView(makingAmount);
newRow.addView(netRate);
newRow.addView(total);
table.addView(newRow);
}
});
}
}
And after a few button clicks we have: 
点击几下按钮后，我们有：
Now as stated you will definitely need to do some legwork on your end to parse the data correctly but this should be more than enough to get you up and running.
现在如上所述，你肯定需要在你的头上做一些工作来正确地解析数据，但这应该足以让你开始运行。
