Java Arraylist indexoutofbounds异常

所以我只是出于个人原因制作了一个小应用程序。基本上，它所做的就是从一个网站解析xml，然后返回一个颜色、标题和作者的列表，然后在listview中显示所有内容。它有点工作，但有时我会得到这些IndexOutofBoundsSexceptions，例如，总是出现在for循环中。更好地解释for循环。结果是一个数组列表。listview中的每一行由3个元素组成：标题、用户名和颜色。for循环在数组中迭代，基本上将值分配给行，因此最初第一个元素将分配给title，第二个元素分配给username，依此类推。这种模式只会重复。如果有人看到问题，甚至知道更好的解决方法，请分享：）

代码如下：

public class ColorsActivity extends ListActivity {
    /** Called when the activity is first created. */
    private int selection = 0;
    private String info;
    private ArrayList<String> myArr = new ArrayList<String>();
    private int resultOffset=0;
    private TextView settings;
    private SearchResults sr = new SearchResults();
    private ArrayList<SearchResults> results = new ArrayList<SearchResults>();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        settings = (TextView) findViewById(R.id.settings_text);

        final ListView lv = getListView();
        lv.setDividerHeight(0);

        colorTask refTask = new colorTask(); 
        refTask.execute();

        settings.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                colorTask refTask = new colorTask(); 
                refTask.execute();
