TabLayout+ViewPager实现tab和页面联动效果
xml中：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns: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>
代码中使用：
public class MainActivity extends AppCompatActivity {
private TabLayout toolbar_tl_tab;
private ViewPager vp_container;
private String[] titles = {"标题1", "标题2", "标题3", "标题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="页面" />
</LinearLayout>
注意：
1、模式相关
使用滚动模式，特点是超过屏幕可以滚动显示：
toolbar_tl_tab.setTabMode(TabLayout.MODE_SCROLLABLE);
使用屏幕等分模式，特点是显示tab的宽度是屏幕等分后的宽度：
toolbar_tl_tab.setTabMode(TabLayout.MODE_FIXED);
