【问题描述】：

我正在尝试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();

但我得到以下异常：

为什么会出现这个错误？我该如何解决这个错误？

尝试添加异常。并找到它发生的地方。然后轻松找出问题
我找不到错误所在。

您是否尝试以相反的顺序从计数到 0 删除行？

【解决方案1】：

请致电table.removeAllViews();

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

【解决方案2】：

即使你还没有给出你的布局，我也会写这个答案，但我猜你已经在上面使用了 strechColumn。

告诉我你可以读到这个;)

你可以在这里找到解释

简而言之，带有可拉伸列的空 TableLayout 似乎崩溃了……
