android - 带有复选框的android ListView 中未触发复选框单击事件

Question

我正在尝试实现一个带复选框的 android ListView 。但是，我无法获得我的复选框的点击事件。

如果我将复选框监听器放在适配器类上，我可以使代码正常工作。但是我需要主类的信息。

使用主类，我可以在单击时获取 ListView 的事件，但不能使用 lv.onItemClick 获取复选框。但是，我需要单击一次 ListView 并再次单击复选框才能触发复选框事件。我需要单独的复选框事件和 ListView 单击事件。有什么帮助吗？谢谢

列表的 XML Relative布局之外还有线性布局。

<RelativeLayout
    android:background="@android:color/transparent"
    android:layout_width="wrap_content"

主事件处理程序

    lv.setOnItemClickListener(new OnItemClickListener() 
    {


            public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
            {
                   checkbox = (CheckBox) view.findViewById(R.id.cbPaper);
                   checkbox.setOnClickListener(new View.OnClickListener() {
                     public void onClick(View v) 
                     {
                         Log.w("do something", "do something" );
                     } });

            }
    });

}

你在 xml 中为 checkBox 提到了 android:clickable="false"...所以 checkBox 不能监听点击事件..最好把Adapter 类中的监听器..

您setOnCheckedChangeListener 而不是setOnClickListener

    checkBox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView,
                boolean isChecked) {
            // TODO Auto-generated method stub
        }
    });
