java - 为什么我无法显示默认的 Android 行选择颜色？

Question

我正在使用此代码来实现 ListView 部分:

  public class ListSample extends ListActivity implements OnItemClickListener{   

    public final static String ITEM_TITLE = "title";   
    public final static String ITEM_CAPTION = "caption";   
    public Resources resources;
    public static Uri path;
    ImageAdapter customAdapter;
    private SeparatedListAdapter adapter;
    public static File file;
    public static ProgressDialog  m_progressDialog;
    public static ListView list;

    @Override  
    public void onCreate(Bundle icicle) {   
        super.onCreate(icicle);  
        setContentView(R.layout.main);

        // create our list and custom adapter   
        adapter = new SeparatedListAdapter(this); 

       // customAdapter =new ImageAdapter(ListSample.this, R.layout.list_item,mList);

        adapter.addSection("Local documents:", new ArrayAdapter<String>(this,   
            R.layout.list_item, new String[] { "WindowsONE Mobile PK", "WindowsorONE Moldings","Filet for a burger video" }));
        adapter.addSection("Non-local resources:", new ArrayAdapter<String>(this,   
                R.layout.list_item, new String[] { "Launch Photo slideshow link", "Dealer locator link" }));
        adapter.addSection("Send emails:", new ArrayAdapter<String>(this,   
                R.layout.list_item, new String[] { "Send Dealer Locator email", "Send Catalog email","Send install instrucation link" })); 
        //For extra Information in Listview    
        //adapter.addSection("Non-local resources:", new SimpleAdapter(this, security, R.layout.list_complex,   
        //new String[] { ITEM_TITLE, ITEM_CAPTION }, new int[] { R.id.list_complex_title, R.id.list_complex_caption }));        
        list = getListView();
        list.setAdapter(adapter);   
        list.setTextFilterEnabled(true);
        list.setOnItemClickListener(this); 
       }
}

如果我运行这个应用程序，一切正常。
但是，当选择任何行时，操作已完成，但我看不到任何突出显示颜色，就像选择了该行一样(就像默认的 android 行选择颜色一样)。

那么，我应该做什么才能使它成为可能？

我想在选择特定行时显示突出显示颜色。

您的 rowitem.xml 必须具有背景颜色。删除它，您将看到默认的突出显示颜色。如果您想自定义突出显示，请按照 Flybirdx 建议使用选择器
