我想在我的项目中添加菜单处理程序.我也阅读了http://developer.android.com/guide/topics/ui/menus.html,它非常简单,但图标未显示.我很迷茫.我甚至以编程方式添加了一个菜单项.

我的代码是:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    menu.add(0, 0, 0, "Quit").setIcon(R.drawable.ic_launcher);
    getMenuInflater().inflate(R.layout.menu, menu);
    return true;
}

并在xml中:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Single menu item 
         Set id, icon and Title for each menu item 
    -->
    <item android:id="@+id/menu_bookmark" 
          android:icon="@drawable/update"
          android:title="@string/Update" />

</menu>

是否可以删除标签栏中显示的底线？未选中时为灰色.

是否有可能将黄色变成其他东西？

我想将tabhost的默认蓝色更改为红色.

<style name="AppTheme" parent="android:Theme.Light.NoTitleBar">
          <item name="android:tabWidgetStyle">@drawable/tab_indicator_holo</item>
          </style>

tab_indicator_holo.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_holo" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_holo" />

    <!-- Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_holo" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_holo" />

    <!-- Pressed -->
    <!--    Non focused states -->
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
    <item android:state_focused="false" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />

    <!--    Focused states -->
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
    <item android:state_focused="true" android:state_selected="true"  android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />
</selector> …
