java - 将 ArrayList 值动态传递给其他 ArrayList

Question

我有四个长度相同的数组(例如 array1、array2...array4)，我想将这些数组的值动态传递到示例数组，以便我可以添加条件和得到相应的值。我该怎么做？

   public SectionListItem[] exampleArray = { // Comment to prevent re-format
           new SectionListItem("array1 data","array2 data","array3 data", "array4 data")

    };

    private StandardArrayAdapter arrayAdapter;
    private SectionListAdapter sectionAdapter;
    private SectionListView listView;


    @Override
    public void onCreate(final Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        arrayAdapter = new StandardArrayAdapter(this, R.id.example_text_view, exampleArray);
        sectionAdapter = new SectionListAdapter(getLayoutInflater(), arrayAdapter);

        listView = (SectionListView) findViewById(android.R.id.list);



        setListAdapter(sectionAdapter);
        listView.setAdapter(sectionAdapter);



    }

Answer 1

这是一个简单的例子:

public class array3 {
    public static void main(String[] args) {
        int ar3[]={33,45,67,87,34,56};
        int ar4[]={5,8,9,22,3,4};
        List list1=new ArrayList();
        List list2=new ArrayList();
         for (int i = 0; i < ar3.length; i++) {
            list1.add(ar3[i]);
        }
   for (int i = 0; i < ar4.length; i++) {
            list2.add(ar4[i]);
        }
        list1.addAll(list2);
        System.out.println(list);           
    }
}
