java.lang.ArrayIndexOutOfBoundsException：length = 6; index = 6 | String.xml

Question

在我的小程序，我想顯示從我String.xml 東西我normaly使用它來做到這一點：

public void putText() { 
    String[] text1 = getResources().getStringArray(R.array.text1); 
    String[] text2 = getResources().getStringArray(R.array.text2); 


    if(selecter >= MAX) { 
     selecter = 0; 
    } 
    else { 
     selecter++; 
    } 

    // Texte anzeigen und Shown table auf true setzen. 
    // normally selecter instead of 6 
    txt_text1.setText(text1[6]); 
    txt_text2.setText(text2[6]); 
} 

而是「selecter」時是6至9之間（九更是MAX變量）的應用程序崩潰與此錯誤：

這裏也是我的string.xml

<string-array name="text1"> 
    <item>You would have everything you want</item> 
    <item>You can go back in time when you want</item> 
    <item>You gain the ability to communicate with animals</item> 
    <item>You gain any one super-power of your choice (aside from immortality)</item> 
    <item>You would become the greatest player in your favorite sport</item> 
    <item>You gain omniscience (infinite knowledge of everything)</item> 
    <item>You become the most talented musician in the world (any instrument)</item> 
    <item>Instead of Dying, you regenerate</item> 
    <item>You wil have unlimited money</item> 
    <item>Everyone on earth love and adore you</item> 
</string-array> 
<string-array name="text2"> 
    <item>you don\'t understand the human language anymore.</item> 
    <item>you can only talk to one person per each travel.</item> 
    <item>you lose the ability to communicate with humans</item> 
    <item>you lose your ability to swim</item> 
    <item>you would constantly be criticized</item> 
    <item>you have it for 24 hours, and afterwards you gain permanent down syndrome.</item> 
    <item>you cannot earn any money from your talent.</item> 
    <item>you only can regenerate 12 times, and each time you look like a different person but retain all memories.</item> 
    <item>you can never sleep again.</item> 
    <item>never fall in love yourself.</item> 
</string-array> 

我在String.x嘗試了短文本毫升，但我仍然得到了消息...而這隻發生在六和MAX（9）

任何建議，爲什麼？

Answer 1

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=6; index=6

意味着你正在試圖在數組的索引6長度爲6到接入元件，但陣列是基於0的索引，這意味着第一元件處於不0位置1。因此，一個6個元素的數組中的最大指數是指數5

你的錯，可能是在這一行：

if(selecter >= MAX) 

應該

if(selecter > MAX) 

但是你不顯示什麼是MAX值。它不能> 6。在你的代碼中的某處，你應該將其定義爲int MAX = 6;

Answer 2

你可以增加MAX的值。 也許MAX = MAX + 1;
