所以，我有以下的code。在适配器：

So I have the following code in the adapter:

@Override
    public boolean isEnabled(int position) 
    {
         GeneralItem item = super.getItem(position);
         boolean retVal = true;


            if (item != null)
            {
                if (currSection != some_condition)
                retVal = !(item.shouldBeDisabled());
            }
         return retVal;
     }


    public boolean areAllItemsEnabled() 
    {
        return false;
    }

在这里问：那么，如果我在初始绑定禁用我的项目，我现在养在屏幕上的活动和需要，使他们所有的无论什么。难道我又重新绑定这一切之后执行该操作？

Question here: So if I disabled my item during initial binding, now I raise the event on the screen and need to enable them all no matter what. Do I rebind it all again after that action is performed?

例如：

onCreate{

// create and bind to adapter
// this will disable items at certain positions 

}

onSomeClick{

I need same listview with same items available for click no  matter what the conditions of positions are, so I need them all enabled. What actions should I call on adapter? 

}

现在的问题是，我可以有一个很长的列表视图了。它想支持6000项。因此，重新绑定它肯定不是一个选项。

The problem is I can have a really long listview too. It suppose to support 6000 items. So rebinding it certainly is not an option.

推荐答案

那你的适配器上有一个实例变量：

What about having an instance variable on your adapter:

boolean ignoreDisabled = false;

然后在 areAllItemsEnabled ：

public boolean areAllItemsEnabled() {
    return ignoreDisabled;
}

，然后在的IsEnabled 的开头：

public boolean isEnabled(int position) {
    if (areAllItemsEnabled()) {
        return true;
    }
     ... rest of your current isEnabled method ...
}

然后就可以在两种模式之间通过设置切换 ignoreDisabled 恰当，并呼吁废止在的ListView 。

请注意，除了的IsEnabled 可能是不必要的;它只是似乎更完整一点。

Note that the addition to isEnabled is probably unneeded; it just seems a bit more complete.
