更改自定義列表視圖中列表項的背景顏色

我有一個自定義列表視圖，其中包含7個文本視圖..我已經創建了一個自定義的線性佈局，然後我填充它...我什麼想要做的是設置一個自定義顏色...當用戶點擊列表項並保持突出顯示，直到他點擊另一個項目...我將如何做到這一點... ...更改自定義列表視圖中列表項的背景顏色

這是自定義佈局對於listItems中......

而我的列表佈局..

<?xml version="1.0" encoding="utf-8"?>

     android:text="© India Transact Services Ltd." 
     android:textColor="#000000" 
     android:textSize="15dp" /> 

</RelativeLayout>

而繪製的顏色xml文件...

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- Selected Item --> 
    <item android:drawable="@android:color/darker_gray" android:state_selected="true"/> 
    <item android:drawable="@android:color/darker_gray" android:state_focused="true"/> 
    <!-- Default Item --> 
    <item android:drawable="@android:color/white" /> 
</selector>

而且我的代碼....

public class Void extends Activity { 
    ListView lmenu; 
    View Vlistselector; 
    String s; 
    View layout; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     // TODO Auto-generated method stub 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.voidlist); 

     Menu Menu_data[] = new Menu[] { 
       new Menu("29/09/2012", "05:40", "2234 xxxx xxxx 1990", "100", 
         "10"), 
       new Menu("09/12/2012", "00:34", "2234 xxxx xxxx 1990", "99",

       new Menu("23/11/2012", "07:40", "2234 xxxx xxxx 1990", "44", 
         "5") }; 

     MenuAdapter adapter = new MenuAdapter(this, R.layout.voidlisttext, 
       Menu_data); 

     lmenu = (ListView) findViewById(R.id.Lvvoid); 

     lmenu.setAdapter(adapter); 
     // lmenu.setSelector(R.drawable.listcolorselector); 
     lmenu.setOnItemClickListener(new OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> ada, View v, int position, 
        long id) { 
       // TODO Auto-generated method stub 

       /* 
       * v.setSelected(true); 
       */ 
       v.setBackgroundColor(Color.parseColor("#FCD5B5")); 

       if (!(Vlistselector == null) && Vlistselector != v) 
        Vlistselector.setBackgroundColor(Color 
          .parseColor("#EEEEEE")); 
       Vlistselector = v; 

       Toast.makeText(getApplicationContext(), 
         String.valueOf(position + 1), Toast.LENGTH_LONG).show(); 
      } 
     }); 

     findViewById(R.id.BLogout).setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       finish(); 
      } 
     }); 
    } 

    public class Menu { 
     public String date; 
     public String time; 
     public String cardno; 
     public String amnt; 
     public String tip; 

     public Menu() { 
      super(); 
     } 

     public Menu(String date, String time, String cardno, String amnt, 
       String tip) { 
      super(); 
      this.date = date; 
      this.time = time; 
      this.cardno = cardno; 
      this.amnt = amnt; 
      this.tip = tip; 

     } 
    } 

    public class MenuAdapter extends ArrayAdapter<Menu> { 

     Context context; 
     int layoutResourceId; 
     Menu data[] = null; 

     public MenuAdapter(Context context, int layoutResourceId, Menu[] data) { 
      super(context, layoutResourceId, data); 
      this.layoutResourceId = layoutResourceId; 
      this.context = context; 
      this.data = data; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      View row = convertView; 
      MenuHolder holder = null; 

      if (row == null) { 
       LayoutInflater inflater = ((Activity) context) 
         .getLayoutInflater(); 
       row = inflater.inflate(layoutResourceId, parent, false); 

       holder = new MenuHolder(); 
       holder.date = (TextView) row.findViewById(R.id.TvVLdate); 
       holder.time = (TextView) row.findViewById(R.id.TvVLtime); 
       holder.cardno = (TextView) row.findViewById(R.id.TvVLcardno); 
       holder.amnt = (TextView) row.findViewById(R.id.TvVLamnt); 
       holder.tip = (TextView) row.findViewById(R.id.TvVLtip); 
       row.setTag(holder); 

      } else { 
       holder = (MenuHolder) row.getTag(); 
      } 

      Menu Menu = data[position]; 
      holder.date.setText(Menu.date); 
      holder.time.setText(Menu.time); 
      holder.cardno.setText(Menu.cardno); 
      holder.amnt.setText(Menu.amnt); 
      holder.tip.setText(Menu.tip); 

      return row; 
     } 

     public class MenuHolder { 
      TextView date; 
      TextView time; 
      TextView cardno; 
      TextView amnt; 
      TextView tip; 
     } 
    } 
}

我想是不是顏色較暗的灰色一套新的自定義顏色... 。我是否以正確的方式做到了，或者有沒有其他辦法可以做到？

View listColor;//declare this at the top

做它的onclick的ListViewItem的

@Override 
protected void onListItemClick(ListView list, View view, int position, long id) { 

if(listColor!=null){ 
    listColor.setBackgroundColor(Color.BLACK); 
    listColor=view; 
}else{ 
    listColor=view; 
} 
listColor.setBackgroundColor(Color.BLUE); //intead of blue you can change it to something you want like darkergray 
//show toast on the clicked item 
String selectedValue = (String) getListAdapter().getItem(position); 
Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show(); 

}

ok..let我試試.... – Audi

使用此代碼它，它只有一個item..but突出的許多項目選擇問題...我的意思是..例如..如果我有8個項目在列表中..而且我只能看到3個項目（其餘我必須滾動查看）..如果我點擊第一個項目...它會突出顯示第四和第七項... – Audi

你能告訴你如何爲你的列表視圖編寫適配器嗎？ –

對於這種情況，您應該在運行時使用setBackground（）而不是依靠選擇器。
