Question

我已通过为每一行扩展ListView来实施自定义LinearLayout。每行都有一个小缩略图，一个文本和一个check box。 list view已正确部署，我可以毫无问题地滚动和浏览它。

但是ListView似乎根本没有响应setOnItemClickListener()，所以我必须通过在每行的文本getView()中设置点击监听器来找到解决方法当我试图重用adapter时，这显然会产生问题。有没有人有解决方案？

Answer 1

试试这个对于ListView，

final ListView list = (ListView) findViewById(R.id.list);
list.setItemsCanFocus(false);

另外，请确保CheckBox内的列表项设置为focusable false

android:focusable="false"
android:focusableInTouchMode="false"

Answer 2

对于将项目视图设置为CheckBox的ListView

android:focusable="false"
android:clickable="false"

您是否在扩展适配器类中创建了任何ViewHolder？如果是，那么在setOnItemClickListener（）中创建一个占位符的实例可能会像这样工作。

@Override
    protected void onListItemClick(ListView l, View v, int position, long id) {        
        View rowView = v;
        if (rowView == null) {
            LayoutInflater inflater = this.getLayoutInflater();
                // GET INFLATE OF YOUR LAYOUT.
            rowView = inflater.inflate(R.layout.projectpeopledescrate, null);
             // CUSTOM ViewHolder Class Created in Adapter.
// name,title,comment are my components on the same listview clicked item.
            PPDViewHolder viewHolder = new PPDViewHolder();
            viewHolder.name     = (TextView) rowView.findViewById(R.id.ppeopledescrvname);
            viewHolder.title    = (TextView) rowView.findViewById(R.id.ppeopledescrvtime);
            viewHolder.comment  = (TextView) rowView.findViewById(R.id.ppeoplervcomment);
            viewHolder.hiddenLayout = (RelativeLayout) rowView.findViewById(R.id.hiddenCommentPanel); 
            rowView.setTag(viewHolder);
        }
          // ANOTHER object instance to apply new changes.
        PPDViewHolder holder = (PPDViewHolder) rowView.getTag();
// I've setted up visibility over the components. You can set your onClickListener over your buttons.
        holder.comment.setVisibility(View.GONE);
        holder.name.setVisibility(View.GONE);
        holder.title.setVisibility(View.GONE);
        holder.hiddenLayout.setVisibility(View.VISIBLE);
        holder.hiddenLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.MATCH_PARENT));
        holder.hiddenLayout.bringToFront();

    }

希望，你想要一样的东西。祝你好运！

我有这段代码

this.mListView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                Log.v(TAG,"loul");
            }
        });

但它不起作用

所以我让juste把一个onItemSelectedListener放在它下面并且它工作Oo：

this.mListView.setItemsCanFocus(false);
this.mListView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
        Log.v(TAG,"loul");
    }
});
//listener for nothing but it allow OnItemClickListener to work
this.mListView.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {

    }
});

设置这些属性：

    v.imageView.setFocusable(false);
    v.imageView.setFocusableInTouchMode(false);

用于 list_item.xml 文件中的所有UI元素。

如果您的适配器集中未解决此问题：

setOnItemClickListener（）不适用于自定义ListView @Android
