我的自定义选项卡布局XML文件
<?xml version="1.0" enCoding="utf-8"?><relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID" androID:layout_wIDth="fill_parent" androID:layout_height="fill_parent" androID:orIEntation="horizontal" ><TextVIEw androID:ID="@+ID/tab_Title" androID:layout_wIDth="fill_parent" androID:layout_height="fill_parent" androID:layout_centerHorizontal="true" androID:layout_centerVertical="true" /> <Imagebutton androID:layout_wIDth="wrap_content" androID:layout_height="wrap_content" androID:layout_alignParentRight="true" androID:layout_centerVertical="true" androID:src="@drawable/ic_action_refresh"/></relativeLayout>
Actionbar代码:
final Actionbar actionbar = getActionbar(); //Because there is no 'parent' when navigating from the action bar,the home button for the Action bar is Disabled. actionbar.setHomebuttonEnabled(false); //Specify that the actionbar will include a tabbed navigation actionbar.setNavigationMode(Actionbar.NAVIGATION_MODE_TABS); // Setting up the VIEwPager rowingVIEwPager,attaching the RowingFragmentPagerAdapter and setting up a Listener for when the // user swipes between sections. rowVIEwPager = (VIEwPager) findVIEwByID(R.ID.pager); rowVIEwPager.setAdapter(rowAdapter); rowVIEwPager.setonPagechangelistener(new VIEwPager.SimpleOnPagechangelistener() { @OverrIDe public voID onPageSelected(int position) { actionbar.setSelectednavigationItem(position); } }); // For loop to add tabs for each fragment to the actionbar for (int tab_counter = 0; tab_counter < rowAdapter.getCount(); tab_counter++) { Tab new_tab = actionbar.newTab(); new_tab.setCustomVIEw(R.layout.custom_tab); TextVIEw tab_Title = (TextVIEw) new_tab.getCustomVIEw().findVIEwByID(R.ID.tab_Title); tab_Title.setText(rowAdapter.getTabTitle(tab_counter)); new_tab.setTabListener(this); // Add tab with specifIEd text as well as setting this activity as the TabListener. actionbar.addTab(new_tab); } rowVIEwPager.setoffscreenPagelimit(2); //Sets the number of off-screen fragments to store and prevent re-load. Will increase if future fragments are added. }解决方法 问题在于不是自定义actionbar布局本身,而是改变样式.默认的Actionbar有一个属性,左边和右边的填充是16dp.您可以在标签布局中执行任何 *** 作,但不会覆盖此选项.
为此,我在Actionbar选项卡的styles.xml中编写了一个新样式,我在其中覆盖了该填充并将其应用于应用程序主题中的actionbarTabStyle属性.这是我的新styles.xml,它显示了这一变化.
