从onItemClick确定AutoCompleteTextView [英] Determine AutoCompleteTextView from onItemClick

问题描述

是否有可能从回调的参数onItemClick？

Is it possible to determine the originating AutoCompleteTextView from the parameters of the callback onItemClick?

我有以下的回调函数，如果我点击选择，弹出窗口的AutoCompleteTextView的一个项目是正确触发：

I have the following callback function, which is correctly triggered if I click on an item of the selection-popup-window of the AutoCompleteTextView:

public void onItemClick(AdapterView<?> adaptView, View view, int position, 
        long id) {
}

我知道，我可以实施自己的每TextView的监听器类的，但我想，以确定哪些AutoCompleteTextView发起点击单从回调函数的参数 - ？这是可能的。

I know, that I can implement an own per-textview listener class, but I would like to determine which AutoCompleteTextView initiated the click solely from the parameters of the callback function - is this possible?

推荐答案

我没有正面回答这个问题（我认为这是不可能的）。但我用的解决方法来达到同样的目的（找到 AutoCompleteTextView 从内部onItemClick）：

I do not have a positive answer to the question (I think it is not possible). But I use a workaround to reach the same goal (find AutoCompleteTextView from within onItemClick):

我定义了下面的类，它可以用来修改 onItemClick 来电提供 AutoCompleteTextView 作为第二参数（而不是原始的查看参数）。

I defined the following class, which can be used to modify the onItemClick call to provide the AutoCompleteTextView as second parameter (instead of original View param).

public class AutoCompleteTextViewClickListener implements OnItemClickListener {
       AutoCompleteTextView mAutoComplete;
       OnItemClickListener mOriginalListener;

       AutoCompleteTextViewClickListener(AutoCompleteTextView acTextView, 
               OnItemClickListener originalListener) {
           mAutoComplete = acTextView;
           mOriginalListener = originalListener;
       }

       public void onItemClick(AdapterView<?> adView, View view, int position,
               long id) {
           mOriginalListener.onItemClick(adView, mAutoComplete, position, id);
       }       
}

这可以通过以下方式使用：

This can be used in the following way:

myTextView.setOnItemClickListener(myListener);

你必须写：

myTextView.setOnItemClickListener(
        new AutoCompleteTextViewClickListener(myTextView, myListener));

现在，每当onItemClicked由TextView的触发，而不是原来的视图值的参考AutoCompleteTextView可用

Now, whenever onItemClicked is triggered by the TextView, instead of the original view value the reference to the AutoCompleteTextView is available.
