MaterialTabs

介绍：

在android l 之前的设备上实现带有Material Design动画风格的选项卡tab切换功能。实现的方式是运用support.v7.widget.Toolbar 。

运行效果：

使用说明：

xml layout

<!-- for Text Tabs -->
<it.neokree.materialtabs.MaterialTabHost
        android:id="@+id/materialTabHost"
        android:layout_width="match_parent"
        android:layout_height="48dp" >
<!-- for icon tabs -->
<it.neokree.materialtabs.MaterialTabHost
        android:id="@+id/materialTabHost"
        android:layout_width="match_parent"
        android:layout_height="48dp"
        app:hasIcons="true" >

应用Material风格主题（来自于兼容包）：

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/light_blue_500</item>
<item name="colorPrimaryDark">@color/light_blue_800</item>
<item name="colorAccent">@color/grey_1000</item>
<item name="windowActionBar">false</item>
</style>

和ViewPager一起使用：

MaterialTabHost tabHost;
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tabHost = (MaterialTabHost) this.findViewById(R.id.materialTabHost);
        pager = (ViewPager) this.findViewById(R.id.viewpager);
        // init view pager
        pagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());
        pager.setAdapter(pagerAdapter);
        pager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
            @Override
            public void onPageSelected(int position) {
                // when user do a swipe the selected tab change
                tabHost.setSelectedNavigationItem(position);
            }
        });
        // insert all tabs from pagerAdapter data
        for (int i = 0; i < pagerAdapter.getCount(); i++) {
            tabHost.addTab(
                    tabHost.newTab()
                            .setIcon(getIcon(i))
                            .setTabListener(this)
                            );
    }
}
@Override
    public void onTabSelected(MaterialTab tab) {
        // when the tab is clicked the pager swipe content to the tab position
        pager.setCurrentItem(tab.getPosition());
    }
