I am previously working on PHP and js , and recently I am working on android listview However, I encountered a problem in creating a custom adapter for listview

public View getView(int arg0, View arg1, ViewGroup arg2) {
        // TODO
        if (arg1 == null) {
            arg1 = myInflater.inflate(R.layout.grid, arg2, false);
        }
        TextView name = (TextView) arg1.findViewById(R.id.text1);
        TextView desc = (TextView) arg1.findViewById(R.id.text2);
        ImageView image = (ImageView) arg1.findViewById(R.id.image1);
        if (arg0 < images.length) {
            image.setImageResource(images[arg0]);
        }
        name.setText(names[arg0]);
        // name.setText(arg0);
        // desc.setText(images.length);
        desc.setText(description[arg0]);
        return arg1;
    }

The problem is I have 3 array of content to pass to the listview grid, for the first two array, there are 10 element and the last one have 3 only. So , it is out of boundries for the last one. I added a condition to check whether it exceed 3 , but args0 seems not increased according to the row?

if (arg0 < images.length) {
                image.setImageResource(images[arg0]);
            }

The first three row and some other rows also has image setted, why is that and how to fix this? thanks

首先，正确地使用“image.length()”而不是“image.length”。

其次，如果您检查 Android Developer for ImageView，您会发现 ImageView 没有像 .length() 这样的方法。

我的第一个猜测是，您将包含您的值的 ArrayList 与您的 ImageView 混合在一起，这只是为了显示目的。
