我无法以编程方式在同一行中设置数组文本视图

Question

我有一个字符串，逗号分隔，从mysql数据库女巫中分裂成一个数组。 我的问题是，当我尝试以编程方式将它们放在表行中时，它会在新行中显示每个拆分值。我想在同一行中显示它，有 4 列。 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);
}

您必须创建一行，并将列(分隔字符串(放入该行中。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 一样格式化，否则它将不起作用。如果您有一个订单的 POJO 并使用这个订单会更好。
