java.lang.ArithmeticException：在清除表中除以零

标签： android logcat

我试图通过以下代码清除表格：

int count = table_layout_acc_statement.getChildCount();
                for (int i = 0; i < count; i++) {
                    View child = table_layout_acc_statement.getChildAt(i);
                    if (child instanceof TableRow) ((ViewGroup) child).removeAllViews();

但是我得到以下例外：

为什么我收到此错误？我该如何解决这个错误？

2 个答案:

答案 0 :(得分：1)

jsut call table.removeAllViews(); 

TableLayout table = (TableLayout) findViewById(R.id.myTable);       
table.removeAllViews();

答案 1 :(得分：0)

即使你没有给出你的布局，我也会写这个答案，但我猜你已经使用了strechColumn了。

有些东西告诉我你可以读这个;）

你可以在这里找到解释

为了简化它，带有可伸缩列的空TableLayout似乎崩溃......
