网格视图项目单击颜色变化

我在一个活动中有一个网格我需要排序我写了排序逻辑这里是我的代码。但问题是当我试图点击任何网格项目。该项目的背景并没有改变，有没有办法来改变项目背景网格视图项目单击颜色变化

HashMap<String, Integer> map = new HashMap<String, Integer>(); 
    ValueComparator bvc = new ValueComparator(map); 
    TreeMap<String, Integer> sorted_map = new TreeMap<String, Integer>(bvc); 

    map.put("Windows", sharedPref.getInt("Windows", 0)); 
    map.put("iOS", sharedPref.getInt("iOS", 0)); 
    map.put("Android", sharedPref.getInt("Android", 0)); 
    map.put("Blackberry", sharedPref.getInt("Blackberry", 0)); 
    map.put("Java", sharedPref.getInt("Java", 0)); 
    map.put("JQuery", sharedPref.getInt("JQuery", 0)); 
    map.put("Phonegap", sharedPref.getInt("Phonegap", 0)); 
    map.put("SQLite", sharedPref.getInt("SQLite", 0)); 
    map.put("Thread", sharedPref.getInt("Thread", 0)); 
    map.put("Video", sharedPref.getInt("Video", 0)); 
    sorted_map.putAll(map); 

    iconList = new ArrayList<Integer>(); 
    Map<String, Integer> treeMap = new TreeMap<String, Integer>(sorted_map); 

    for (Map.Entry<String, Integer> entry : treeMap.entrySet()) { 
    System.out.println("Key : " + entry.getKey() 
             + " Value : " + entry.getValue()); 


    sortedList.add(entry.getKey());

gridView.setOnItemClickListener(new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View v, 
       int position, long id) { 
      v.setBackgroundColor(Color.RED); 
     }

对不起，它不是在我的情况下工作我需要为我的网格选择效果我不需要更改项目颜色，并感谢您的答案 – Kumar 2015-02-10 10:54:16

什么样的影响？ – GIGAMOLE 2015-02-10 10:55:04

做一个活动XML布局grid_color_selector.xml并在自定义的GridView布局Android上使用此布局：background =“@ drawable/grid_color_selector”。

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

     <item android:drawable="@android:color/holo_blue_light" android:state_pressed="true"/> 
     <item android:drawable="@android:color/holo_blue_light" android:state_selected="true"/> 
     <item android:drawable="@color/white"/> 

    </selector>

您可以将选择器定义为drawable并将其添加为网格项的背景。

首先，创建一个包含你选择一个新的可绘制资源文件：

<selector xmlns:android="http://schemas.android.com/apk/res/android" > 
    <item android:state_pressed="false" android:state_focused="true" android:color="@color/your_pressed_color" /> 
    <item android:state_pressed="true" android:color="@color/your_pressed_color" /> 
    <item android:color="@color/your_default_color" /> 
</selector>

之后，这个选择添加到您的网格项：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="@drawable/your_selector" 
    android:orientation="vertical"> 

    <!--The grid item layout elements--> 

</LinearLayout>

使用此

/res/drawable/grid_view_item.xml

<item android:state_pressed="true" > 
    <shape> 
     <solid android:color="@color/grid_item_pressed"/> 
    </shape> 
</item>

/res/values/colors.xml

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <color name="grid_item_pressed">#ffaa66</color> 
</resources>

现在把android:background="@drawable/grid_view_item"属性，在xml含网格视图
