在setOnTabChangedListener()方法中根据标签的切换情况来设置myMenuSettingTag
Override
public void onTabChanged(String tagString) {
// TODO Auto-generated method stub
if (tagString.equals("One")) {
myMenuSettingTag = 1;
}
if (tagString.equals("Two")) {
myMenuSettingTag = 2;
}
if (tagString.equals("Three")) {
myMenuSettingTag = 3;
}
if (tagString.equals("Four")) {
myMenuSettingTag = 4;
}
if (myMenu != null) {
onCreateOptionsMenu(myMenu);
}
}
然后onCreateOptionsMenu(Menu menu) 方法中通过MenuInflater过滤器动态加入MENU
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
// Hold on to this
myMenu = menu;
myMenu.clear();//清空MENU菜单
// Inflate the currently selected menu XML resource.
MenuInflater inflater = getMenuInflater();
//从TabActivity这里获取一个MENU过滤器
switch (myMenuSettingTag) {
case 1:
inflater.inflate(myMenuResources[0], menu);
//动态加入数组中对应的XML MENU菜单
break;
case 2:
inflater.inflate(myMenuResources[1], menu);
break;
case 3:
inflater.inflate(myMenuResources[2], menu);
break;
case 4:
inflater.inflate(myMenuResources[3], menu);
break;
default:
break;
}
return super.onCreateOptionsMenu(menu);
}
menu 布局
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://www.easck.com/apk/res/android"> <group android:id="@+id/group_a"><item android:id="@+id/item_a" android:icon="@drawable/gimp" android:title="Gimp"></item> </group> </menu>
