我关注了这个线程： OnCheckChanged 侦听器仅适用于 customlistview 中的第一个复选框

用于为我的 android 应用程序中的 CheckBox 编写 onCheckedListener() 代码。上面的链接有listview，在我的例子中我有一个gridview。

我目前的代码是：

public View getView(int position, View convertView, ViewGroup parent)
{
    ViewHolder holder;
    ImageView imgView = null;

        if (convertView == null) {

            holder = new ViewHolder(); 
            LayoutInflater ltInflate = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE ); 
            convertView = ltInflate.inflate(R.layout.griditem, null);

            holder.textview1 = (TextView) convertView.findViewById(R.id.grid_item_alert_date);
            holder.textview2 = (TextView) convertView.findViewById(R.id.grid_item_alert_time);
            holder.textview3 = (TextView) convertView.findViewById(R.id.grid_item_alert_type);

            holder.imageview    = (ImageView) convertView.findViewById(R.id.grid_item_image);
            holder.checkbox = (CheckBox) convertView.findViewById(R.id.checkbox_ack);
            convertView.setTag(holder);

        }
        else
        {   
            holder = (ViewHolder) convertView.getTag();
        }

        holder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

              @Override
              public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                 // TODO Auto-generated method stub
                  Toast.makeText(context, " checkbox checked", Toast.LENGTH_SHORT).show();

              } });

        holder.textview1.setId(position);
        holder.textview2.setId(position);
        holder.textview3.setId(position);
        holder.imageview.setId(position);
        holder.checkbox.setId(position);


        holder.textview1.setText("Text 1 ");
        holder.textview2.setText("Text 2 ");
        holder.textview3.setText("Text 3 ");
        holder.checkbox.setChecked(false);
        holder.imageview.setImageBitmap(bitmap);
        holder.id = position;



        return convertView;

}

当我选中我的应用程序崩溃的复选框时，我想知道为什么？

更新：这是选中复选框后的 logcat 输出：

好的，所以我在定义复选框的 layout.xml 中发现了问题我添加了这行导致找不到事件处理程序

android:onClick="onCheckboxClicked"

删除了这个，代码现在可以正常工作。

感谢 Sam 和其他人的观看。
