如何更改 android 2.3-actionbarsherlock 上的标签样式

Question

您好，我想更改 android

到

我还想修改它的背景和图标。

我正在使用actiobarsherlock 库。

这是我尝试过的

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="?attr/actionBarSize"
            android:layout_weight="0"
            style="@style/ActionBarTabStyle.Example"
            android:orientation="horizontal"
            android:tabStripEnabled="false" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_weight="0" />

        <com.mainapp.CustomViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1" />
    </LinearLayout>

</TabHost>

风格

<style name="ActionBarTabStyle.Example" parent="@style/Widget.Sherlock.Light.ActionBar.TabView">
        <item name="android:background">@drawable/tab_indicator_ab_example</item>
    </style>

-

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

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

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

谢谢！

更新：

你使用 actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); 我所有的三个片段都使用 actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);所以标签 不显示。我试图同时显示选项卡和列表导航，但现在 在职的。我想在我的 碎片。我怎样才能实现它？ – 约翰·史密斯 1 小时前

你不能两者兼得。在这种情况下我会推荐的是

a) 您可以开始使用抽屉式导航/滑动菜单模式，而不是使用 Navigation_mode_list。

https://developer.android.com/design/patterns/navigation-drawer.html

b) 使用 viewpager + viewpager 条代替选项卡。然后就可以使用 Naviagation_mode_list 了。

c) 代替使用navigation_mode_list，您可以有一个操作栏菜单项，有人可以按下它来启动一个对话框。

原创

ActionBar 中的选项卡和 Tabhost 中的选项卡实际上是不同的，并且不使用相同的样式集。这可以解释为什么你改变风格没有做任何事情。

现在，您可以采取几种方法来获得类似 Holo 的风格。

• 您可以使用 ActionBarSherlock.Tabs + Fragments 而根本不使用 TabHost。 （我的建议）
• 您可以直接使用Holo Colors Generator 设置 Tabhost 的样式（实际上特定的 TabHost 需要更多的努力）

我重新开始 (ActionBarSherlock.Tabs + Fragments) 的原因是 Android 开发的发展方向。使用 Fragments 可以让您拥有完全可重用的代码块。此外，viewpager 还可以让您进行流畅的滑动操作以添加交互性。这是实现它并在 2.2 模拟器上测试的代码。

SectionsPagerAdapter mSectionsPagerAdapter;

/**

ViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Set up the action bar.
    final ActionBar actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    // Set up the ViewPager with the sections adapter.
    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    // When swiping between different sections, select the corresponding
    // tab. We can also use ActionBar.Tab#select() to do this if we have
    // a reference to the Tab.
    mViewPager
            .setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
                @Override

                    actionBar.setSelectedNavigationItem(position);
                }
            });

    // For each of the sections in the app, add a tab to the action bar.
    for (int i = 0; i < mSectionsPagerAdapter.getCount(); i++) {
        // Create a tab with text corresponding to the page title defined by

        // Return a DummySectionFragment (defined as a static inner class
        // below) with the page number as its lone argument.
        Fragment fragment = new DummySectionFragment();
        Bundle args = new Bundle();
        args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1);
        fragment.setArguments(args);
        return fragment;
    }

    @Override

        // Show 3 total pages.
        return 4;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        Locale l = Locale.getDefault();
        switch (position) {
        case 0:
            return "Simple";
        case 1:
            return "Contacts";
        case 2:
            return "Custom";

        return null;
    }
}

/**

public static class DummySectionFragment extends Fragment {
    /**

     */

    public DummySectionFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_main_dummy,
                container, false);
        TextView dummyTextView = (TextView) rootView
                .findViewById(R.id.section_label);
        dummyTextView.setText(Integer.toString(getArguments().getInt(
                ARG_SECTION_NUMBER)));
        return rootView;
    }
}

 }

为了生成这段代码，我使用了 File->New-> Other -> Android Folder -> Android - Activity -> Blank Activity -> Navigation style 设置为 Fixed Tabs + swipe。但是，您不能直接将其与 actionbarsherlock 一起使用，因为您需要将 Actionbar 变量替换为 getSupportActionBar ，就像我在上面的代码中所做的那样。
