推荐答案

要避免在ListView具有的CheckBox的问题，你可以采取一个布尔数组初始化在开始false，然后如实相应​​的位置上排列在复选框在ListView检查。这不会引起麻烦的复选框选中状态，当你向前和向后移动的应用程序或滚动的ListView。

To avoid the problems with CheckBoxes in a ListView you can take a Boolean array initialized false in the beginning and then making true the corresponding position in the array where checkbox is checked in the ListView. This will not cause a trouble in checked state of checkboxes when you move forward and backward in your application or scroll the ListView.

下面是如何设置checkboxstate是布尔数组：

Here is how to set checkboxstate is the boolean array:

 holder.checkbox.setOnClickListener(new View.OnClickListener() {

                    public void onClick(View v) {
                        if (((CheckBox) v).isChecked())
                            checkBoxState[pos] = true;
                        else
                            checkBoxState[pos] = false;

                    }
                });

和那么这将保持复选框选中，当你滚动状态也不会自动改变：

and then this will keep the checkboxes checked when you scroll and the state will not automatically change:

holder.checkbox.setChecked(checkBoxState[pos]);
