在ImageAdapter类本教程中，为http：//开发商。 android/resources/tutorials/views/hello-gridview.html

In the ImageAdapter class of this tutorial, developer.android/resources/tutorials/views/hello-gridview.html

我想创建和填充使用for循环的数组。但似乎不管我在哪里把它，它会导致错误。

I would like to create and populate an array using a for loop. But it seems no matter where I place it, it causes an error.

例如，在私人语境mContext; 我把下面的，它导致错误。我认为循环是好的，我只是不知道在那里我可以把它。结果

For example, under private Context mContext; I put in the following and it causes an error. I think the loop is good, I'm just not sure where I can put it.

私有String [] myString的;对于（INT数= 0;＆号LT; = 12;数++）{ MyString的[数字] =形象+号;}

推荐答案

创建和填充在构造函数中的阵列。不要忘了实际上的实例化数组你开始填充它。

Create and populate the array in the constructor. Don't forget to actually instantiate the array before you start populating it.

public ImageAdapter(Context c) { mContext = c; myString = new String[12]; //create array for (int number = 0; number < myString.length; number++) { myString[number] = "image" + number; } }
