Answer 1

com.viavilab.androiddrawing.MainActivity.onCreate(MainActivity.java:50) 07-31 10:28:10.311: 

它说你的错误是在方法的第50行的onCreate和错误是你的指数是从数组中，检查你的代码，请。

Answer 2

代替原来的代码中使用

for(int i=0; i<title.length -1 ;i++) 

尝试。但我需要检查array.length和array.length -1是如何工作的。 :)

我认为当涉及到index和length的array,array.length -1是解决方案。但something.length在File InputSteam或其他人。

并请理解我们index的array这样的：

title [] = [ index 0 , index 1, index 2 , ... index (array.lenth -1) ] 

现在你的代码的index是7和你array.length只有7.如果是index 7价值？ :)

Answer 3

这条线路是好的，你是从阵列获得每一个项目：

for(int i=0; i<title.length;i++) { 

，问题就出现在这里：

List_Item item=new List_Item(description[i], title[i],Image_Arrays.icons[i]); 

阵列 “Image_Arrays” 越小则数组 “称号”那就抛出异常。您可以测试有长度：

Log.d("ArrayLength", "title: " + String.valueOf(title.length) + " icons: "+ String.valueOf(Image_Arrays.icons.length))
