选择在滚动中的Andr​​oid ListView控件列表项移动颜色 [英] Selected list item color moves on scrolling the listView in Android

问题描述

在我的Andr​​oid应用我使用列表视图。在code为列表视图如下：

In my Android application I am using listview. The code for list view is as follows

 <ListView
    android:id="@+id/inputselect_listview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:choiceMode="singleChoice"
    android:footerDividersEnabled="true"
    android:headerDividersEnabled="true"
    android:listSelector="@drawable/list_selector"
    android:splitMotionEvents="true" >
 </ListView>

当用户从列表视图则列表项发生改变背景颜色中选择一个项目，根据该行

When user selected one item from the listview then background color of list item changes according to this line

android:listSelector="@drawable/list_selector"

编辑：list_selector.xml

list_selector.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_window_focused="false" android:state_selected="true"
    android:drawable="@android:color/transparent" />
<item android:state_selected="true"
    android:drawable="@android:color/transparent" />
<item android:state_pressed="true" android:state_selected="false"
    android:drawable="@android:color/transparent" />
<item android:state_selected="false"
    android:drawable="@color/blue_train" />
</selector>

list_selector.xml是绘制文件夹指定颜色。
现在的问题是，当我选择列表视图一个项目，并滚动列表，然后选择项目的背景颜色也向下移动/向上按滚动。
使所选项目的背景颜色仍然是它在滚动请提供给我的解决方案。

list_selector.xml is in drawable folder to specify color. Now the problem is that when I select one item from listview and scrolls the list then selected item background color also move downward/upward according to scrolling. Please provide me solution so that selected item background color remains as it is on scrolling.

编辑：这里选择单一色item.Blue滚动列表视图的截图保留，因为它是

Here the screenshot of scrolling listview by selecting single item.Blue color remains as it is

请咨询。

推荐答案

似乎未清除的状态在选择导致此。使用一个像

seems uncleared states in selector causing this . use one like

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 

  <!-- Selected --> 
  <item 
    android:state_focused="true" 
    android:state_selected="false" 
    android:drawable="@drawable/focused"/> 

  <!-- Pressed -->
  <item 
    android:state_selected="true" 
    android:state_focused="false"
    android:drawable="@drawable/pressed" /> 

<!-- default -->
  <item  android:drawable="@drawable/default" /> 

</selector>
