java.lang.ArithmeticException：在結算表被零除

Question

我想通過下面的代碼來清除表：

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(); 

但我得到以下異常：

我爲什麼得到這個錯誤？我怎樣才能解決這個錯誤？

Answer 1

僅僅指剛打電話table.removeAllViews();

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

Answer 2

我會寫這個答案，即使你沒有給你的佈局，但是我想你有使用strechColumn就可以了。

東西告訴我，你能讀懂這一點;）

how to fix ArithmeticException error in android

而且你可以在這裏找到

Divide by zero error in .xml file

的解釋要簡短，與strechable列空TableLayout似乎碰撞...
