所以，我有一个ListFragment带有自定义布局的自定义布局，它有一个CursorAdapter将自定义视图传递给ListView. 其ListView选择模式设置为MultiChoiceModal。但是，无论我是在正常模式下选择一个项目还是在操作模式下选择几个项目，所选项目都不会突出显示。为了解决这个问题，我尝试了一个选择器。

<?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>

但是，将其应用于ListView列表List Selector只会导致应用程序崩溃，并且当我尝试运行它时会出现此错误：

它还会导致 Eclipse 抱怨：

在将选择器应用于自定义视图的根布局（特别是作为背景）时，我从 Eclipse 得到了同样的抱怨，所以逻辑表明我会得到类似的错误。有什么我做错了吗？

编辑：嗯，多亏了 vArDo，没有更多的崩溃。但是选择器实际上并没有做任何事情。这是列表项布局的 xml，对于那些可能可以看到如何真正开始工作的人：

<?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>

需要成为可ListView绘制对象（请参阅文档），因此您的 XML 文件中的每个标签都必须包含在其中。只需更改为（您可以使用相同的值），您当前的错误就会消失。android:listSelectoritemselectorandroid:drawableandroid:colorandroid:drawable

替换后的文件应如下所示：

<?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，显然我应该更频繁地挖掘源代码。我最终做的是采用列表项的根布局：

<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" >

并添加了一个属性：

<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" >

这增加了在android.R.layout.simple_list_item_activated_1等人中看到的行为。

一种替代但更长的方法是在方法中手动设置 listView 项目的背景颜色getView()。

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;
}

在 listView 中OnItemClickListener，添加：

customAdapter.setSelectedId(position)

虽然这种方法效率不高，但它在我的项目中运行良好。此外，避免使用静态 ViewHolder 类或使用这种方法回收视图。
