通过点击按钮在 ArrayAdapter 数组上添加值

Question

我想计算出如何在 month 数组中添加另一个字符串，然后通过点击按钮在一个list view中动态的显示。现在我可以显示指定的数组，但是不知道如何添加计数变量，就是应该在点击按钮后再添加到 array list中的。请问如何实现？

public class Test extends Activity implements OnClickListener,
        OnItemClickListener {
    Button test;
        ListView list;
    String month[] = { "January", "February", "March", "April", "May", "June",
            "July", "August", "September", "October", "November", "December" };
    public static int count = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test);
        test = (Button) findViewById(R.id.button1);
        test.setOnClickListener(this);
        list = (ListView) findViewById(R.id.tlist);
        list.setAdapter(new  ArrayAdapter<String> (this,
                android.R.layout.simple_list_item_1, month));
    }
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch (v.getId()) {
        case R.id.button1:
            count++;
            //Add count value to end of array
            break;
        }
    }
}

显然String数组是指定长度的了，无法进行添加
你得用List或者ArrayList
然后在click中写:
list.add(""+count);
adapter.notifyDataSetChanged();
