android - 我无法在 Android 中单击 ListView？

Question

我制作了一个使用联系人同步的应用程序。我列出了以下联系信息，包括照片、姓名和电话号码。我成功地在自定义 ListView 中列出了所有这些内容，但我无法单击 ListView。它看起来像锁定，无法单击它。

但是我对另一个 Activity 做了同样的程序。使用自定义 ListView 但我可以单击此 View 并且它工作正常。

问题是什么？这是我的示例编码:

    ListView settingsList = (ListView) findViewById(R.id.manage_track_listView);
    ArrayList<ContactList> MySettingsList = new ArrayList<ContactList>();

    ContactList setting1 = new ContactList("contact name 1", "Number 1", null);
    ContactList setting2 = new ContactList("contact name 2", "Number 2", null);
    ContactList setting3 = new ContactList("contact name 3", "Number 3", null);

    MySettingsList.add(setting1);
    MySettingsList.add(setting2);
    MySettingsList.add(setting3);

    ContactList list[] = new ContactList[MySettingsList.size()];

    for(int i=0;i<MySettingsList.size();i++) {

        ContactList mySettings = MySettingsList.get(i);
        list[i] = new ContactList(mySettings.getName(), mySettings.getNumber(), mySettings.getImageIcon());
    }

    ContactListAdapter adapter = new ContactListAdapter(this, R.layout.manage_track_list_custom_view, list);
    settingsList.setAdapter(adapter);
    System.out.println("before listener");
    settingsList.setOnItemClickListener(new OnItemClickListener() {

        @Override


        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            // TODO Auto-generated method stub

            System.out.println("Clicked " + position);
        }
    });
    System.out.println("after listener");

这里的 ContactList 是一个包含联系人姓名、号码和 imageBlob 的 byte[] 的类。如果图像为空，我将默认的 ic_launcher 设置为联系人图像。适配器类是:

public class ContactListAdapter extends ArrayAdapter<ContactList> {

    Context context;
    int layoutResourceId;
    ContactList objects[] = null;

    View row;

    public ContactListAdapter(Context context, int layoutResourceId, ContactList[] objects) {
        super(context, layoutResourceId, objects);
        // TODO Auto-generated constructor stub

        this.context = context;
        this.layoutResourceId = layoutResourceId;
        this.objects = objects; 
        System.out.println(objects[1].getName());
        System.out.println(objects[1].getNumber());
        System.out.println(objects[1].getImageIcon());
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        row = convertView;
        final ContactListHolder holder;

        if ( row == null ) {

            LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);

            holder = new ContactListHolder();
            holder.image    = (ImageView) row.findViewById(R.id.contactImage);
            holder.name     = (TextView) row.findViewById(R.id.contactName);
            holder.number   = (TextView) row.findViewById(R.id.contactNumber);
            holder.check    = (CheckBox) row.findViewById(R.id.selectedContact);

            row.setTag(holder);

        } else {

            holder = (ContactListHolder)row.getTag();
        }

        ContactList contact = objects[position];
        if(contact.imageIcon != null) {

            Bitmap imgBitmap = BitmapFactory.decodeByteArray(contact.imageIcon, 0, contact.imageIcon.length);
            holder.image.setImageBitmap(imgBitmap);
        } else {

            holder.image.setImageResource(R.drawable.ic_launcher);
        }

        holder.name.setText(contact.name);
        holder.number.setText(contact.number);
        holder.check.setChecked(objects[position].isSelected());    

        return row;

    }

    static class ContactListHolder {

        ImageView image;
        TextView name;
        TextView number;
        CheckBox check;
    }
}

我有超过 100 个联系人，所以只添加了 3 个对象。在此联系人列表中，我成功收到联系人图像、姓名、号码。

ListView 无法点击是什么问题？我希望你们中的任何一个能指导我。提前致谢。

感谢大家。现在只需在我的所有 subview 中添加 android:focusable="false" 即可获得结果。感谢您的指导。

在嵌套 View 中， subview 总是首先获得所有触摸事件。如果你想让父 View (在你的例子中是 listView 行)获得触摸事件，你必须在子事件上返回 false 或将它们设置为 android:clickable="false" list 。
