标题和fragment联动效果已经封装好了,非常方便

<android.support.design.widget.TabLayout
    android:id="@+id/tabs"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:tabMode="scrollable"></android.support.design.widget.TabLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/vp"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/tabs"></android.support.v4.view.ViewPager>

 

配置要特别注意

dependencies {
    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])
    testCompile ‘junit:junit:4.12‘
    compile ‘com.android.support:appcompat-v7:23.1.1‘
    compile ‘com.android.support:design:23.1.1‘
    compile ‘com.android.support:support-v4:23.1.1‘
}

 

 

public class MyFragment extends Fragment {
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.myfragment,null);
        return view;
    }
}
public class MyAdapter extends FragmentPagerAdapter {

    private List<String> titles;
    private List<Fragment> fragments;

    public MyAdapter(FragmentManager fm) {
        super(fm);
    }

    public MyAdapter(FragmentManager fm, List<String> titles, List<Fragment> fragments) {
        super(fm);
        this.titles = titles;
        this.fragments = fragments;
    }

    @Override
    public Fragment getItem(int position) {
        return fragments.get(position);
    }

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

    @Override
    public CharSequence getPageTitle(int position) {
        return titles.get(position);
    }
}
public class MainActivity extends AppCompatActivity {

    private TabLayout tabLayout;
    private ViewPager viewPager;
    private List<String> titles;
    private List<Fragment> fragments;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tabLayout = (TabLayout) findViewById(R.id.tabs);
        viewPager = (ViewPager) findViewById(R.id.vp);
        initTitles();
        initFragments();
        MyAdapter adapter = new MyAdapter(getSupportFragmentManager(), titles, fragments);
        viewPager.setAdapter(adapter);
        tabLayout.setupWithViewPager(viewPager);
    }

    private void initTitles() {
        titles = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            titles.add("标题" + i);
        }
    }

    private void initFragments() {
        fragments = new ArrayList<>();
        for (int i = 0; i < titles.size(); i++) {
            fragments.add(new MyFragment());
        }
    }

}
