无法将自定义选择器添加到ListView中

因此，我有一个ListFragment自定义布局，该自定义布局具有将自定义视图传递到ListView的自定义CursorAdapter。 ListView的选择模式设置为MultiChoiceModal。但是，选定的项目永远不会突出显示，无论是在正常模式下选择一个项目还是在操作模式下选择多个项目。为了解决这个问题，我尝试了一个Selector。无法将自定义选择器添加到ListView中

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:color="@android:color/holo_blue_dark" 
     android:state_pressed="true" /> 
    <item android:color="@android:color/holo_blue_light" 
     android:state_checked="true" /> 
    <item android:color="@android:color/holo_blue_bright" 
     android:state_selected="true" /> 
</selector>

Hoowever，将其应用到了ListView作为列表List Selector只是导致应用程序崩溃和这个错误，当我尝试运行它：

当将选择器应用于自定义视图的根布局（特别是作为背景）时，我得到了与Eclipse相同的抱怨，因此逻辑规定我会得到一个类似的错误。有什么我做错了吗？

编辑︰好吧，由于vArDo，没有更多的崩溃。但是选择者实际上并没有做任何事情。下面是列表项的布局，对于那些谁也许可以看到如何真正得到这个开始工作的xml：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/itemLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <TextView 
     android:id="@+id/NameView" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentTop="true" 
     android:text="Name" 
     android:textAppearance="?android:attr/textAppearanceLarge" 
     tools:ignore="HardcodedText" /> 

    <TextView 
     android:id="@+id/balanceView" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" 
     android:layout_below="@+id/NameView" 
     android:text="Balance" 
     android:textAppearance="?android:attr/textAppearanceSmall" 
     tools:ignore="HardcodedText" /> 

    <ImageView 
     android:id="@+id/favStar" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentTop="true" 
     android:layout_marginRight="10dp" 
     android:layout_marginTop="10dp" 
     android:contentDescription="@string/accessFav" 
     android:src="@android:drawable/btn_star_big_on" 
     android:visibility="gone" /> 

</RelativeLayout>

好的，显然我应该更经常地通过源代码来挖掘。我最终什么事做了以我的列表项的根布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/itemLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" >

而且增加了一个属性：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/itemLayout" 
    android:background="?android:attr/activatedBackgroundIndicator" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" >

这增加在android.R.layout.simple_list_item_activated_1等人看到的行为。

在ListView的android:listSelector需要是绘制（see documentation），所以每个item标签在您的XML selector文件中必须有android:drawable。只需将android:color更改为android:drawable（您可以使用相同的值），并且当前的错误应该消失。

你替换后的文件应该是这样的：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:drawable="@android:color/holo_blue_dark" 
     android:state_pressed="true" /> 
    <item android:drawable="@android:color/holo_blue_light" 
     android:state_checked="true" /> 
    <item android:drawable="@android:color/holo_blue_bright" 
     android:state_selected="true" /> 
</selector>

好吧，它不会崩溃了，但我必须将我的选择器格式化为错误，因为它实际上并没有做任何事情。 – MowDownJoe 2013-04-07 02:27:25

@MowDownJoe我怀疑你的项目视图不透明，因此'ListView'选择器永远不可见。你能否在你的问题中包括你如何定义项目视图布局？ – vArDo 2013-04-07 19:05:56

好的。编辑。 – MowDownJoe 2013-04-07 20:37:04

一个选择，但这样做的更长的方法就是手动设置ListView的项目的背景颜色getView()方法。

class CustomAdapter extends BaseAdapter{ 
... 

int selectedID; 

public void setSelectedId(int n) 
{ 
selectedID = n; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
.... 
if(position == selectedID) 
convertView.setBackgroundColor(someColor); 
return convertView; 
}

而且在ListView的OnItemClickListener，添加：

customAdapter.setSelectedId(position)

虽然这一点，方法是不是有效的，但它在我的项目完美。 此外，避免使用此方法使用静态ViewHolder类或回收视图。
