2个AutoCompleteTextView，如何知道已选择哪个视图 [英] 2 AutoCompleteTextView's, how to know which view has been selected

问题描述

似乎是重复，但不是.

我的布局中有2个AutoCompleteTextView.从地址，到地址.我需要知道其中哪个人启动了下拉列表.

I have 2 AutoCompleteTextView's in my layout. From Address, To Address. I need to know which one of them initiated the drop down list.

由于两者都使用相同的商品布局，所以我重复了此尝试并尝试过，仍然没有运气.

Since both were using the same item layout, I duplicated it and tried, still no luck.

AutoCompleteTextView的初始化

    fromAutoComplete = new AutoComplete(this, R.layout.fromautocomplete);
    fromAutoComplete.setNotifyOnChange(true);
    fromAddress = (AutoCompleteTextView) findViewById(R.id.fromAddress);
    fromAddress.setAdapter(fromAutoComplete);
    fromAddress.setOnItemClickListener(this);
    fromAddress.setOnItemSelectedListener(this);

    toAutoComplete = new AutoComplete(this, R.layout.toautocomplete);
    toAutoComplete.setNotifyOnChange(true);
    toAddress = (AutoCompleteTextView) findViewById(R.id.toAddress);
    toAddress.setAdapter(toAutoComplete);
    toAddress.setOnItemClickListener(this);
    toAddress.setOnItemSelectedListener(this);

请注意R.layout.to自动完成和R.layout.from自动完成

两者与下面相同.

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:minLines="3"
android:layout_marginBottom="15dp"
android:textSize="15dp" 
android:text="sample text"
android:marqueeRepeatLimit="marquee_forever"/>

为了调试这些值，我放置了一些Log语句

To debug the values, I have put some Log statements

@Override
public void onItemSelected(AdapterView<?> parent, View who, int position, long id) {
    Log.e("Taxeeta", ">"+parent.getId()+":"+who.getId()+":"+id) ;
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {      
    Log.e("Taxeeta", parent.getId()+":"+view.getId()+":"+id) ;
}

日志输出为

07-02 17:24:14.773:E/Taxeeta(12103):-1:-1:0

07-02 17:24:14.773: E/Taxeeta(12103): -1:-1:0

坦率地说，这很烂，为什么id的parent，view和id返回如此无用的值?

Frankly, this just sucks, why would id's for parent, view and id return such useless values ?

我在这里错过了一些非常基本的东西.

I am missing something really basic here.

推荐答案

我想我明白了.答案是2折.

I think I figured it out. The answer is 2 fold.

1. onItemClick返回的id值对于第一次自动完成返回 0 ，对于第二次自动完成返回 1

1. The id value returned by onItemClick returns 0 for the first autocomplete, and 1 for the second autocomplete

07-02 17:24:14.773:E/Taxeeta(12103):-1:-1:0

07-02 17:24:14.773: E/Taxeeta(12103): -1:-1:0

07-02 17:24:14.773:E/Taxeeta(12103):-1:-1:1

07-02 17:24:14.773: E/Taxeeta(12103): -1:-1:1

布局文本视图的应该具有ID.这是在onItemClick

对于FromLayout

For FromLayout

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/fromautocomplete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:minLines="3"
android:layout_marginBottom="15dp"
android:textSize="15dp" 
android:text="sample text"
android:marqueeRepeatLimit="marquee_forever"/>

对于ToLayout

For ToLayout

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toautocomplete"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:minLines="3"
android:layout_marginBottom="15dp"
android:textSize="15dp" 
android:text="sample text"
android:marqueeRepeatLimit="marquee_forever"/>
