索引超出界限例外。 array

我想從我的數組中添加項目到列表視圖中，但我總是得到一個異常。索引超出界限例外。 array

下面

是如何我添加的項目代碼：

items.add(new SectionItem("President")); 
       for(int a = 0; a <= presList.size(); a++) 
       { 
        String name = presList.get(a); 
        String companyName = presList.get(a + 1); 
        Log.d("company name:", companyName); 
        items.add(new EntryItem(name,companyName)); 
       }

logcat的輸出：

也可以使用'foreach'到aviod索引問題。 –

使用

for(int a = 0; a <= presList.size()-1; a++)

for(int a = 0; a < presList.size(); a++)

代替

for(int a = 0; a <= presList.size(); a++)

謝謝，我解決了我的問題。我會在答案允許的時候打勾:) – Jolene

最受歡迎的朋友!!! :) –

應該

for(int a = 0; a < presList.size(); a++) 
{ 
     String name = presList.get(a); 
     String companyName = presList.get(a); 
     Log.d("company name:", companyName); 
     items.add(new EntryItem(name,companyName)); 
}

比方說，我們有一個ArrayList用5項

所以訪問的ArrayList開始從元素索引0至4
