android - 如何使用 Fragments 自定义标题栏和标签

Question

我正在编写一个程序，其中我使用 Fragments 来处理选项卡，但我需要对我的 UI 进行一些更改

我的 UI 需要一些更改，5 个小问题:

问题一:如何改变TITLE BAR的背景色(我要红色)

问题2:如何改变标签的背景颜色(我想要灰色)

问题3:如何改变选中标签的颜色(我想要红色)

问题4:如何在Tabs中的文字上方显示Icon

问题5:如何将分享按钮放在右侧标题栏上

list .xml:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.test.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

MainActivity.java:

 public class MainActivity extends FragmentActivity {

        ViewPager ViewPager;
        TabsAdapter TabsAdapter;

        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);         

            //create a new ViewPager and set to the pager we have created in Ids.xml
            ViewPager = new ViewPager(this);
            ViewPager.setId(R.id.pager);
            setContentView(ViewPager);


            //Create a new Action bar and set title to strings.xml
            final ActionBar bar = getActionBar();
            bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
            bar.setTitle(R.string.app_name);

            //Attach the Tabs to the fragment classes and set the tab title.
            TabsAdapter = new TabsAdapter(this, ViewPager);

            TabsAdapter.addTab(bar.newTab().setText("About"),
                    FragAbout.class, null);
            TabsAdapter.addTab(bar.newTab().setText("Location"),
                    FragLocation.class, null);
            TabsAdapter.addTab(bar.newTab().setText("Menus"),
                    FragMenus.class, null);
            TabsAdapter.addTab(bar.newTab().setText("Reservation"),
                    FragReservation.class, null);
            TabsAdapter.addTab(bar.newTab().setText("Social"),
                    FragSocial.class, null);

            if (savedInstanceState != null) {
                bar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0));
            }

        }

        @Override
        protected void onSaveInstanceState(Bundle outState) {
            super.onSaveInstanceState(outState);
            outState.putInt("tab", getActionBar().getSelectedNavigationIndex());
        }

        // create TabsAdapter to create tabs and behavior
        public static class TabsAdapter extends FragmentPagerAdapter
        implements ActionBar.TabListener, ViewPager.OnPageChangeListener {

            private final Context mContext;
            private final ActionBar mActionBar;
            private final ViewPager mViewPager;
            private final ArrayList<TabInfo> mTabs = new ArrayList<TabInfo>();

            static final class TabInfo {
                private final Class<?> clss;
                private final Bundle args;

                TabInfo(Class<?> _class, Bundle _args) {
                    clss = _class;
                    args = _args;
                }
            }

            public TabsAdapter(FragmentActivity activity, ViewPager pager) {
                super(activity.getSupportFragmentManager());
                mContext = activity;
                mActionBar = activity.getActionBar();
                mViewPager = pager;
                mViewPager.setAdapter(this);
                mViewPager.setOnPageChangeListener(this);
            }

            public void addTab(ActionBar.Tab tab, Class<?> clss, Bundle args) {
                TabInfo info = new TabInfo(clss, args);
                tab.setTag(info);
                tab.setTabListener(this);
                mTabs.add(info);
                mActionBar.addTab(tab);
                notifyDataSetChanged();             
            }

            @Override
            public void onPageScrollStateChanged(int state) {
                // TODO Auto-generated method stub
            }

            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
                // TODO Auto-generated method stub
            }   

            @Override
            public void onPageSelected(int position) {
                // TODO Auto-generated method stub
                mActionBar.setSelectedNavigationItem(position);
            }

            @Override
            public void onTabReselected(Tab tab, FragmentTransaction ft) {
                // TODO Auto-generated method stub
            }

            @Override
            public void onTabSelected(Tab tab, FragmentTransaction ft) {
                Object tag = tab.getTag();
                for (int i=0; i<mTabs.size(); i++) {
                    if (mTabs.get(i) == tag) {
                        mViewPager.setCurrentItem(i);
                    }
                }
            }

            @Override
            public void onTabUnselected(Tab tab, FragmentTransaction ft) {
                // TODO Auto-generated method stub
            }

            @Override
            public Fragment getItem(int position) {
                TabInfo info = mTabs.get(position);
                return Fragment.instantiate(mContext, info.clss.getName(), info.args);
            }

            @Override
            public int getCount() {
                return mTabs.size();
            }

        }

FragAbout.java:

public class FragAbout extends Fragment {

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

            View myFragmentView = inflater.inflate(R.layout.frag_about, container, false);
            return myFragmentView;

    } 

}

我想你已经得到了答案，这就是你开发这个的原因:

无论如何，如果你还在寻找答案，那么

我真的推荐你使用ActionBarStyleGenerator:

使用该工具，您可以轻松地为工具栏中的图形元素设置主题。
