網格視圖項目單擊顏色變化

我在一個活動中有一個網格我需要排序我寫了排序邏輯這裏是我的代碼。但問題是當我試圖點擊任何網格項目。該項目的背景並沒有改變，有沒有辦法來改變項目背景網格視圖項目單擊顏色變化

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);

對不起，它不是在我的情況下工作我需要爲我的網格選擇效果我不需要更改項目顏色，並感謝您的答案 – Kumar 2015-02-10 10:54:16

什麼樣的影響？ – GIGAMOLE 2015-02-10 10:55:04

做一個活動XML佈局grid_color_selector.xml並在自定義的GridView佈局Android上使用此佈局：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>

您可以將選擇器定義爲drawable並將其添加爲網格項的背景。

首先，創建一個包含你選擇一個新的可繪製資源文件：

<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>

之後，這個選擇添加到您的網格項：

<?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>

現在把android:background="@drawable/grid_view_item"屬性，在xml含網格視圖
