Java android listView点击后，选择消失

Question

我想这样做：我有一个列表，每两个项目的颜色是不同的，并希望选择被点击的项目。所选的项目被高亮显示之后却老色彩还原被释放

我这样做： artists_list_background_alternate.xml：

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

<item 
    android:state_selected="false" 
    android:state_pressed="false" 
    android:drawable="@color/sign_out_color" /> 

<item android:state_pressed="true" 
    android:drawable="@color/survey_toplist_item" /> 

<item android:state_selected="true" 
    android:state_pressed="false" 
    android:drawable="@color/survey_toplist_item" /> 

</selector> 

artists_list_backgroundcolor.xml：

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:drawable="@color/grey" android:state_pressed="false" android:state_selected="false" /> 
    <item android:drawable="@color/survey_toplist_item" android:state_pressed="true" /> 
    <item android:drawable="@color/survey_toplist_item" android:state_pressed="false" android:state_selected="true" /> 
    <item android:drawable="@color/survey_toplist_item" android:state_pressed="false" android:state_selected="true" /> 
</selector> 

的Java文件代码::

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View view = convertView; 
     if (view == null) { 
      view = lInflater.inflate(R.layout.listitem, parent, false); 
     } 

     if (position % 2 == 0) { 
      view.setBackgroundResource(R.drawable.artists_list_backgroundcolor); 
     } else { 
      view.setBackgroundResource(R.drawable.artists_list_background_alternate); 
     } 

     ((TextView) view.findViewById(R.id.heading)).setText(data.get(position)); 

     return view; 
    } 


    ListView lvMain = (ListView) findViewById(R.id.list); 
     lvMain.setAdapter(adapter); 

布局xml ::

<ListView 
     android:id="@+id/list" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:cacheColorHint="#00000000" 
     android:dividerHeight="1dp" /> 

而且我不知道我做错了什么

为了使项目高亮显示，您需要为您提供ListViewchoiceMode。例如：

android:choiceMode="singleChoice" 

此外，在您的选择器中为状态android:state_activated="true"添加颜色。
