ListView控件没有在Android 1.5检查项目 [英] ListView not checking items on Android 1.5

问题描述

我正在开发在Eclipse为Android的应用程序。目前，我的目标API级别为3，但我错误地在Android 1.6模拟器（API等级4）测试。在1.6它工作得很好，但在我的1.5与CHOICE_MODE_SINGLE的ListView被点击时，他们并不选择项目。

I'm developing an app for Android in Eclipse. Currently I target API level 3, but I was mistakenly testing on an Android 1.6 emulator (API level 4). On 1.6 it worked fine, but on 1.5 my ListView with CHOICE_MODE_SINGLE does not select items when they are clicked on.

下面是我的ListView XML：

Here's my listview XML:

<ListView 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent" 
    android:layout_weight="1" 
    android:id="@+id/ListDomains" 
    android:layout_margin="5px" 
    android:choiceMode="singleChoice" 
    android:clickable="false"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:descendantFocusability="beforeDescendants"
>
</ListView>

下面是在列表视图中项目的XML：

Here's the XML for the items in the listview:

<?xml version="1.0" encoding="utf-8"?>
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_height="wrap_content" 
    android:id="@+id/domain_list_value"
    android:checkMark="?android:attr/listChoiceIndicatorSingle" 
    android:textAppearance="?android:attr/textAppearanceLarge" 
    android:layout_width="fill_parent" 
>
</CheckedTextView>

我创建一个自定义的ArrayList适配器，让我定制getView。这里的code为DomainArrayAdapter：

I created a custom ArrayList adapter to let me customize getView. Here's the code for DomainArrayAdapter:

public class DomainArrayAdapter extends ArrayAdapter<char[]> {

    private LayoutInflater mInflater;

    public DomainArrayAdapter(Context context, int textViewResourceId,
            List<char[]> objects) {     
        super(context, textViewResourceId, objects);    
        mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if(convertView == null){
            convertView = mInflater.inflate(R.layout.domain_list, null);
        }

        char[] text = super.getItem(position);

        ((CheckedTextView)convertView).setText(text, 0, text.length);
        return convertView;
    }

}

这一切code的工作正常编译对API级别3和在Android 1.6模拟器中运行。但是，对一个1.5模拟器中运行，在ListView项目不点击时确认。

All of this code works fine compiled against API level 3 and run on an Android 1.6 emulator. However, run against a 1.5 emulator, items in the ListView do not check when clicked on.

任何想法？

推荐答案

看来Android 1.5的不尊重choiceMode在ListView XML设置。它设置编程使其正常工作：

It appears Android 1.5 does not respect the choiceMode set in the listview XML. Setting it programatically causes it to work correctly:

    ListView listDomains = (ListView) findViewById(R.id.ListDomains);

    Log.d("app", String.valueOf(listDomains.getChoiceMode())); //prints 0

    listDomains.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

    Log.d("app", String.valueOf(listDomains.getChoiceMode())); //prints 1

有其他人看到这种行为？

Has anyone else seen this sort of behavior?
