listView中item部分可用

事实再一次证明有时候 自己还真的好浮躁，以前只是简单的看过这个程序 只是没有细研，今天用到item 部分可用部分不可用 当返回去查阅时 真汗颜 ，好多东西要不归于遗忘 要不归于不重视  什么时候能看过用过 全部记住就好了 那就不用写这个了

public class List5 extends ListActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setListAdapter(new MyListAdapter(this));
    }

    private class MyListAdapter extends BaseAdapter {
        public MyListAdapter(Context context) {
            mContext = context;
        }

        public int getCount() {
            return mStrings.length;
        }

        @Override
        public boolean areAllItemsEnabled() {
            return true;
        }

        @Override
        public boolean isEnabled(int position) {
            return !mStrings[position].startsWith("-");
        }

        public Object getItem(int position) {
            return position;
        }

        public long getItemId(int position) {
            return position;
        }

        public View getView(int position, View convertView, ViewGroup parent) {
            TextView tv;
            if (convertView == null) {
                tv = (TextView) LayoutInflater.from(mContext).inflate(
                        android.R.layout.simple_expandable_list_item_1, parent, false);
            } else {
                tv = (TextView) convertView;
            }
            tv.setText(mStrings[position]);
            return tv;
        }

        private Context mContext;
    }
    
    private String[] mStrings = {
            "----------",
