我无法以编程方式在同一行中设置数组 textview

Question

我有一个字符串，逗号分隔，来自 mysql 数据库，我拆分成一个数组。 我的问题是，当我尝试以编程方式将它们放入 tablerow 时，它会在新行中显示每个拆分值。我想将它显示在 4 列的同一行中。 这是我的代码：

String currentString = Order_list;
            String[] separated = currentString.split(",");

            TableLayout secondTbl = findViewById(R.id.secondTable);

            for(int i=0;i<separated.length;i++){
                TableRow row= new TableRow(getApplicationContext());
                TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
                row.setLayoutParams(lp);
                row.setBackgroundResource(R.drawable.row_drawable);
                txtOrdprod = new TextView(getApplicationContext());
                row.addView(txtOrdprod);
                TableRow.LayoutParams params = (TableRow.LayoutParams) txtOrdprod.getLayoutParams();
                params.leftMargin = 18;
                params.rightMargin = 10;
                params.topMargin = 10;
                txtOrdprod.setLayoutParams(params);
                txtOrdprod.setTextSize(TypedValue.COMPLEX_UNIT_SP,22);
                txtOrdprod.setTextColor(Color.BLACK);
                txtOrdprod.setTypeface(null, Typeface.BOLD);
                txtOrdprod.setText(separated[i]);
                secondTbl.addView(row,i);
            }

Answer 1

您必须创建一行，并将列（分隔字符串）放入该行。例如：

String orders = "2, Product, 100 Tablets, 50 Eur, 3, Product, 100 Tablets, 75 Eur";

int k = 0;
int startPoint = 0;
List<String> orderList = new ArrayList<>();
for(int i = 0; i < orders.length(); i++)
{
    if(orders.charAt(i) == ',')
    {
        k++;
        if(k == 4)
        {
            String ab = orders.substring(startPoint, i);
            orderList.add(ab);
            startPoint = i + 1;
            k = 0;
        }
    }
}

TableLayout secondTbl = findViewById(R.id.secondTable);

int rowIndex = 0;
for(String order : orderList)
{
    String[] separated = order.split(",");

    TableRow row = new TableRow(getApplicationContext());
    TableRow.LayoutParams lp = new 
    TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, 
    TableRow.LayoutParams.WRAP_CONTENT);
    row.setLayoutParams(lp);
    row.setBackgroundResource(R.drawable.row_drawable);
    secondTbl.addView(row, rowIndex);

    for(int i = 0; i < separated.length; i++)
    {
        txtOrdprod = new TextView(getApplicationContext());
        row.addView(txtOrdprod);
        TableRow.LayoutParams params = (TableRow.LayoutParams) 
        txtOrdprod.getLayoutParams();
        params.leftMargin = 18;
        params.rightMargin = 10;
        params.topMargin = 10;
        txtOrdprod.setLayoutParams(params);
        txtOrdprod.setTextSize(TypedValue.COMPLEX_UNIT_SP,22);
        txtOrdprod.setTextColor(Color.BLACK);
        txtOrdprod.setTypeface(null, Typeface.BOLD);
        txtOrdprod.setText(separated[i]);
    }

    rowIndex++;
}

但请记住，订单字符串需要像示例中的 on 那样格式化，否则将无法正常工作。如果您有一个订单的 POJO 并使用这个订单会更好。
