我知道这个话题已经被讨论过很多次了，但我遇到的问题是不同的。我使用样式更改了操作栏的颜色。但是当我使用操作栏创建选项卡时，选项卡的背景颜色没有改变。所以，问题是如何改变标签的颜色。其次，我想删除选项卡中的下划线。提前感谢任何解决方案。
Layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>Pager Adapter
public class MyFragmentPagerAdapter extends FragmentPagerAdapter{
final int PAGE_COUNT = 2;
/** Constructor of the class */
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
/** This method will be invoked when a page is requested to create */
@Override
public Fragment getItem(int arg0) {
Bundle data = new Bundle();
switch(arg0){
/** Android tab is selected */
case 0:
CreateEvent createEvent = new CreateEvent();
data.putInt("current_page", arg0+1);
createEvent.setArguments(data);
return createEvent;
/** Apple tab is selected */
case 1:
SearchEvent searchEvent = new SearchEvent();
data.putInt("current_page", arg0+1);
searchEvent.setArguments(data);
return searchEvent;
}
return null;
}
/** Returns the number of pages */
@Override
public int getCount() {
return PAGE_COUNT;
}
}Main FragmentActivity:
public class Event extends FragmentActivity{
ActionBar mActionBar;
ViewPager mPager;
Activity myActivity;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.event);
/** Getting a reference to action bar of this activity */
mActionBar = getActionBar();
/** Set tab navigation mode */
mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
/** Getting a reference to ViewPager from the layout */
mPager = (ViewPager) findViewById(R.id.pager);
/** Getting a reference to FragmentManager */
FragmentManager fm = getSupportFragmentManager();
/** Defining a listener for pageChange */
ViewPager.SimpleOnPageChangeListener pageChangeListener = new ViewPager.SimpleOnPageChangeListener(){
@Override
public void onPageSelected(int position) {
super.onPageSelected(position);
mActionBar.setSelectedNavigationItem(position);
}
};
mPager.setOnPageChangeListener(pageChangeListener);
MyFragmentPagerAdapter fragmentPagerAdapter = new MyFragmentPagerAdapter(fm);
mPager.setAdapter(fragmentPagerAdapter);
mActionBar.setDisplayShowTitleEnabled(true);
ActionBar.TabListener tabListener = new ActionBar.TabListener() {
@Override
public void onTabSelected(android.app.ActionBar.Tab tab,
FragmentTransaction ft) {
// TODO Auto-generated method stub
mPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(android.app.ActionBar.Tab tab,
FragmentTransaction ft) {
// TODO Auto-generated method stub
}
@Override
public void onTabReselected(android.app.ActionBar.Tab tab,
FragmentTransaction ft) {
// TODO Auto-generated method stub
}
};
/** Creating Android Tab */
Tab tab = mActionBar.newTab()
.setIcon(R.drawable.ic_action_edit)
.setTabListener(tabListener);
mActionBar.addTab(tab);
/** Creating Apple Tab */
tab = mActionBar.newTab()
.setIcon(R.drawable.ic_action_search)
.setTabListener(tabListener);
mActionBar.addTab(tab);
} 
最佳答案
mActionBar.setStackedBackgroundDrawable(new ColorDrawable(Color.parseColor("#FFFFFF")));
