但现在我想创建动作条/工具栏片段标签

推荐答案

我能够重新正是你在找什么来实现。我现在用的这个库的标签。

I was able to recreate exactly what you are looking to implement. I am using the this Library for the tabs.

这是我创建的视图：

导入库通过依赖或下载项目和导入手动

compile 'com.jpardogo.materialtabstrip:library:1.0.9'

styles.xml

<resources>

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
    </style>
</resources>

MainActivity和放大器;适配器

public class MainActivity extends ActionBarActivity {
    Toolbar toolbar;
    ViewPager viewPager;
    ContactPagerAdapter pagerAdapter;
    PagerSlidingTabStrip pagerSlidingTabStrip;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setLogo(R.mipmap.logo_two);
        toolbar.inflateMenu(R.menu.menu_main);
        viewPager = (ViewPager) findViewById(R.id.pager);
        pagerAdapter = new ContactPagerAdapter(this, getSupportFragmentManager());
        pagerSlidingTabStrip = (PagerSlidingTabStrip) findViewById(R.id.tabs);
        viewPager.setAdapter(pagerAdapter);
        pagerSlidingTabStrip.setViewPager(viewPager);
    }

    public static class ContactPagerAdapter extends FragmentPagerAdapter implements PagerSlidingTabStrip.CustomTabProvider {

        private final int[] ICONS = {R.mipmap.ic_launcher, R.mipmap.ic_launcher};
        Context mContext;
        private Fragment f = null;

        public ContactPagerAdapter(Context ctx, FragmentManager fm) {
            super(fm);
            mContext = ctx;
        }

        @Override
        public int getCount() {
            return ICONS.length;
        }

        @Override
        public Fragment getItem(int position) { // Returns Fragment based on position
            switch (position) {
                case 0:
                    f = new FragmentPageOne();
                    break;
                case 1:
                    f = new FragmentPageTwo();
                    break;
            }
            return f;
        }

        @Override
        public View getCustomTabView(ViewGroup parent, int position) {
            LinearLayout customLayout = (LinearLayout) LayoutInflater.from(mContext).inflate(R.layout.custom_tab, parent, false);
            ImageView imageView = (ImageView) customLayout.findViewById(R.id.image);
            imageView.setImageResource(ICONS[position]);
            return customLayout;
        }
    }
}
