Question

我正在关注指南针listview适配器。来自这个帖子

问题是标题是可点击的。我怎么能禁用它。

如果位置固定很容易，但它们没有修复。

我试过这个但没有运气:(

if (convertView == null) {
    view = (View) inflater.inflate(R.layout.listasheader, null);
   view.setClickable(false);
    // Do some initialization
} else {
    view = convertView;
    view.setClickable(false);

    public interface Item {
        public int getViewType();
        public View getView(LayoutInflater inflater, View convertView);
    }

这里是罗盘代码（来自线程）：

public class TwoTextArrayAdapter extends ArrayAdapter<Item> {
    private LayoutInflater mInflater;

    public enum RowType {
        LIST_ITEM, HEADER_ITEM
    }

    public TwoTextArrayAdapter(Context context, List<Item> items) {
        super(context, 0, items);
        mInflater = LayoutInflater.from(context);
    }

    @Override
    public int getViewTypeCount() {
        return RowType.values().length;

    }

    @Override
    public int getItemViewType(int position) {
        return getItem(position).getViewType();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        return getItem(position).getView(mInflater, convertView);
    }
}

然后我们为实现Item提供类并扩展正确的布局。在您的情况下，您将拥有类似Header类和ListItem类的内容。

   public class Header implements Item {
    private final String         name;

    public Header(String name) {
        this.name = name;
    }

    @Override
    public int getViewType() {
        return RowType.HEADER_ITEM.ordinal();
    }

    @Override
    public View getView(LayoutInflater inflater, View convertView) {
        View view;
        if (convertView == null) {
            view = (View) inflater.inflate(R.layout.header, null);
            // Do some initialization
        } else {
            view = convertView;
        }

        TextView text = (TextView) view.findViewById(R.id.separator);
        text.setText(name);

        return view;
    }

}

然后是ListItem类

    public class ListItem implements Item {
    private final String         str1;
    private final String         str2;

    public ListItem(String text1, String text2) {
        this.str1 = text1;
        this.str2 = text2;
    }

    @Override
    public int getViewType() {
        return RowType.LIST_ITEM.ordinal();
    }

    @Override
    public View getView(LayoutInflater inflater, View convertView) {
        View view;
        if (convertView == null) {
            view = (View) inflater.inflate(R.layout.my_list_item, null);
            // Do some initialization
        } else {
            view = convertView;
        }

        TextView text1 = (TextView) view.findViewById(R.id.list_content1);
        TextView text2 = (TextView) view.findViewById(R.id.list_content2);
        text1.setText(str1);
        text2.setText(str2);

        return view;
    }

}

一个简单的Activity来显示它

public class MainActivity extends ListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        List<Item> items = new ArrayList<Item>();
        items.add(new Header("Header 1"));
        items.add(new ListItem("Text 1", "Rabble rabble"));
        items.add(new ListItem("Text 2", "Rabble rabble"));
        items.add(new ListItem("Text 3", "Rabble rabble"));
        items.add(new ListItem("Text 4", "Rabble rabble"));
        items.add(new Header("Header 2"));
        items.add(new ListItem("Text 5", "Rabble rabble"));
        items.add(new ListItem("Text 6", "Rabble rabble"));
        items.add(new ListItem("Text 7", "Rabble rabble"));
        items.add(new ListItem("Text 8", "Rabble rabble"));

        TwoTextArrayAdapter adapter = new TwoTextArrayAdapter(this, items);
        setListAdapter(adapter);
    }

}

Answer 1

在此getView()

之前的return view;中使用此行

@Override
public View getView(LayoutInflater inflater, View convertView) {


    .....



    text1.setOnClickListener(null);
    return view;
}
