横向滑动Tablayout

横向滑动只需要在布局用Tablyout控件

在此之前在build.gradle里面添加

compile 'com.android.support:design:25.0.1'

下面是布局文件

<android.support.design.widget.TabLayout    android:id="@+id/tb"    android:layout_width="match_parent"    android:layout_height="wrap_content"    app:tabIndicatorColor="#f00"    app:tabMode="scrollable"    app:tabSelectedTextColor="#f0f9"></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.support.v4.view.ViewPager>

主页代码

public class MainActivity extends AppCompatActivity {    private TabLayout tb;    private ViewPager viewp;    String[] title = new String[]{"初学者", "演员", "认真的雪", "火星人来过", "听说", "我好像在哪见过你", "方圆几里", "绅士"};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        tb = (TabLayout) findViewById(R.id.tb);        viewp = (ViewPager) findViewById(R.id.vp);        //默认选中第一个        tb.addTab(tb.newTab().setText(title[0]), true);        addtab();        tb.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {            @Override            public void onTabSelected(TabLayout.Tab tab) {                viewp.setCurrentItem(tab.getPosition());            }            @Override            public void onTabUnselected(TabLayout.Tab tab) {            }            @Override            public void onTabReselected(TabLayout.Tab tab) {            }        });        viewp.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {            @Override            public int getCount() {                return title.length;            }            @Override            public Fragment getItem(int position) {                return Fragment.getInstance(title[position]);            }        });        viewp.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {            @Override            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {            }            @Override            public void onPageSelected(int position) {                tb.getTabAt(position).select();            }            @Override            public void onPageScrollStateChanged(int state) {            }        });    }    private void addtab() {        for (int i = 1; i < title.length; i++) {            tb.addTab(tb.newTab().setText(title[i]), false);        }    }}

ViewPage的setAdapter里面Fragment.getInstance(title[position])传值到Fragment

需要创建一个Fargment

public class Fragment extends android.support.v4.app.Fragment {    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        TextView tv = new TextView(getActivity());        tv.setText(getArguments().getString("title"));        return tv;    }    public static Fragment getInstance(String title) {        Fragment fragment = new Fragment();        Bundle args = new Bundle();        args.putString("title", title);        fragment.setArguments(args);        return fragment;    }}
