TabLayout+ViewPager實現tab和頁面聯動效果
xml中：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android/243768.html">android/95442.html">android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.TabLayout android:id="@+id/toolbar_tl_tab" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:layout_gravity="bottom" app:layout_scrollFlags="scroll" app:tabIndicatorColor="@android:color/holo_green_light" app:tabSelectedTextColor="@android:color/holo_green_light" /> <View android:layout_width="match_parent" android:layout_height="1dp" android:background="#f0f0f0" /> <android.support.v4.view.ViewPager android:id="@+id/vp_container" android:layout_width="match_parent" android:layout_height="match_parent" /></RelativeLayout>
代碼中使用：
public class MainActivity extends AppCompatActivity { private TabLayout toolbar_tl_tab; private ViewPager vp_container; private String[] titles = {"標題1", "標題2", "標題3", "標題4"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); init(); } private void init() { toolbar_tl_tab = (TabLayout) findViewById(R.id.toolbar_tl_tab); vp_container = (ViewPager) findViewById(R.id.vp_container); toolbar_tl_tab.setupWithViewPager(vp_container); toolbar_tl_tab.setTabMode(TabLayout.MODE_SCROLLABLE); vp_container.setAdapter(new FragmentStatePagerAdapter(getSupportFragmentManager()) { @Override public Fragment getItem(int position) { return new PageFragment(); } @Override public CharSequence getPageTitle(int position) { return titles[position]; } @Override public int getCount() { return titles.length; } }); }}碎片：PageFragment
public class PageFragment extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_page, null); return view; }}碎片xml：fragment_page.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:text="頁面" /></LinearLayout>
注意：
1、模式相關
使用滾動模式，特點是超過屏幕可以滾動顯示：
toolbar_tl_tab.setTabMode(TabLayout.MODE_SCROLLABLE);
使用屏幕等分模式，特點是顯示tab的寬度是屏幕等分后的寬度：
toolbar_tl_tab.setTabMode(TabLayout.MODE_FIXED);
