更改焦点上的listview的背景图像

概述我的代码是：ListContacts.javapublicclassListContactsextendsListActivity{@OverridepublicvoidonCreate(BundlesavedInstanceState){super.onCreate(savedInstanceState);System.out.println("ListContacts:onCreate:");Cursorcu

我的代码是：

ListContacts.java

public class ListContacts extends ListActivity { @OverrIDe    public voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    System.out.println("List Contacts : onCreate : ");Cursor cursor = getContentResolver().query(                ContactsContract.Contacts.CONTENT_URI, null,                ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1", null,                "UPPER(" + ContactsContract.Contacts.disPLAY_name + ") ASC");        startManagingCursor(cursor);

ImageCursorAdapter .java

public class ImageCursorAdapter extends SimpleCursorAdapter implements SectionIndexer{public VIEw getVIEw(int pos, VIEw inVIEw, VIEwGroup parent) {        VIEw v = inVIEw;        String phoneNumber = null;        String contactID = null;        // Associate the xml file for each row with the vIEw        if (v == null) {        LayoutInflater inflater = (LayoutInflater) context        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);        v = inflater.inflate(R.layout.contact_ListvIEw, null);        }        this.c.movetoposition(pos);  /**         * Get the strings with the name and number of the person that the         * current row         */        //        String lname = this.c.getString(this.c            .getColumnIndex(EMPLOYEE_name))}    }

ListvIEw.xml

<?xml version="1.0" enCoding="utf-8"?><linearLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    androID:orIEntation="horizontal"    androID:layout_wIDth="fill_parent" androID:paddingleft="5dp" androID:paddingRight="5dp"    androID:layout_height="fill_parent" androID:background="@drawable/ListvIEw_bac">      <linearLayout androID:layout_wIDth="fill_parent"       androID:layout_height="fill_parent"         androID:layout_marginRight="4dp"                androID:orIEntation="horizontal">  <ImageVIEw        androID:ID="@+ID/callimage"         androID:layout_wIDth="36dp"        androID:layout_height="49dp"        androID:clickable="true"         androID:background="@androID:color/transparent"          androID:paddingRight="4dp"           androID:src="@drawable/phone">        </ImageVIEw>      <linearLayout androID:layout_wIDth="fill_parent"      androID:layout_height="wrap_content"        androID:layout_gravity="center"              androID:orIEntation="horizontal" >         <TextVIEw androID:ID="@+ID/contact_name"                androID:textcolor="@color/black"                androID:layout_wIDth="wrap_content"                androID:layout_height="wrap_content"                androID:ellipsize="marquee"                androID:textAppearance="?androID:attr/textAppearanceLarge"                         />            <ImageVIEw        androID:ID="@+ID/favimage"         androID:layout_wIDth="20dp"        androID:layout_height="20dp"        androID:layout_gravity="top|right"        androID:background="@androID:color/transparent"         androID:src="@drawable/favorites" androID:visibility="gone">        </ImageVIEw>       <!--  <TextVIEw androID:ID="@+ID/contact_number"                androID:textcolor="@color/black"                androID:layout_wIDth="wrap_content"                androID:layout_height="wrap_content"                androID:paddingtop="2dp"                androID:textAppearance="?androID:attr/textAppearanceSmall"        /> -->        </linearLayout>        </linearLayout></linearLayout>

我需要更改焦点上的列表视图的图像,文本视图的颜色

解决方法:

添加一个xml文件来管理linearLayout的背景.

List_bg_selector.xml：

<?xml version="1.0" enCoding="utf-8"?><selector xmlns:androID="http://schemas.androID.com/apk/res/androID">    <!-- Active tab -->    <item androID:state_selected="true" androID:state_focused="false"        androID:state_pressed="false" androID:drawable="@drawable/List_selected_bgimage" />    <!-- Inactive tab -->    <item androID:state_selected="false" androID:state_focused="false"        androID:state_pressed="false" androID:drawable="@drawable/List_default_bgimage" />    <!-- pressed tab -->    <item androID:state_pressed="true" androID:drawable="@drawable/List_selected_bgimage" />    <!-- Selected tab (using d-pad) -->    <item androID:state_focused="true" androID:state_selected="true"        androID:state_pressed="false" androID:drawable="@drawable/List_selected_bgimage" /></selector> 

要管理文本颜色,请将文本颜色设置为其他xml.

text_selector.xml：

<?xml version="1.0" enCoding="utf-8"?><selector xmlns:androID="http://schemas.androID.com/apk/res/androID">    <item androID:state_selected="true" androID:color="@androID:color/black"/>    <item androID:state_focused="true" androID:color="@androID:color/black"/>    <item androID:state_pressed="true" androID:color="@androID:color/black"/>    <item androID:color="@androID:color/white"/></selector>
