如何实现在android中包含2个片段的活动左右滑动？
问题描述：
我有一个包含2个片段和两个包含recyclerview的片段的活动。 我需要实现轻扫手势（当我从一侧滑动到另一侧时，需要更改碎片）。 此前我已添加滑动手势，但是当我滑动回收站视图时，将滚动而不是改变碎片。如何实现在android中包含2个片段的活动左右滑动？
你能在执行这一帮助..
感谢

使用TabLayout与ViewPager。为活动中的两个片段创建两个选项卡。 http://www.androidhive.info/2015/09/android-material-design-working-with-tabs/

这是你如何做到这一点：
public class YourActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
setupViewPager(viewPager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new FragmentOne(), "Fragment One");
adapter.addFragment(new FragmentTwo(), "Fragment Two");
viewPager.setAdapter(adapter);
}
private class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> fragmentList = new ArrayList<>();
private final List<String> fragmentTitleList = new ArrayList<>();
ViewPagerAdapter(FragmentManager fragmentManager) {super(fragmentManager);}
@Override
public Fragment getItem(int position) {return fragmentList.get(position);}
@Override
public int getCount() {
return fragmentList.size();
}
void addFragment(Fragment fragment, String title) {
fragmentList.add(fragment);
fragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return fragmentTitleList.get(position);
}
}
}
这是.XML文件：
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

</android.support.design.widget.CoordinatorLayout>
希望它能帮助！

刚刚使用Android TabLayout与ViewPager，你的问题就解决了:)
答
只需使用Tablayout和ViewPager
下面的代码： -
public class DispatchOrderTab extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
public static int int_items = 2 ;
android.support.v4.app.FragmentManager mFragmentManager;
View view;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
getActivity().setTitle("Order");
View x = inflater.inflate(R.layout.activity_dispatch_order_tab,null);
tabLayout = (TabLayout) x.findViewById(R.id.sliding_tabs_dispatchtoken);
viewPager = (ViewPager) x.findViewById(R.id.viewpagerdispatchtoken);
viewPager. setOffscreenPageLimit(2);
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.setupWithViewPager(viewPager);
return x;
}
class MyAdapter extends FragmentPagerAdapter {
Order order;
Home home;
public MyAdapter(FragmentManager fm) {
super(fm);
}
/**
* Return fragment with respect to Position .
*/
@Override
public Fragment getItem(int position)
{
switch (position){
//Here u can put your fragment files for swipe
case 0 : return new Dispatchorder();
case 1 : return new DispatchOrderTokenComplete();
}
return null;
}
@Override
public int getCount() {
return int_items;
}
/**
* This method returns the title of the tab according to the position.
*/
@Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0 :
//Here you can put the name of tabs.
return "Pending Order";
case 1 :
return "Complete Order";
}
return null;
}
}
}
这里的xml： -
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.Weal.sachin.omcom.TabFragment"
android:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="@+id/sliding_tabs_dispatchtoken"
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="#11977c"
app:tabTextColor="#d2cece"
app:tabSelectedTextColor="#fff"
/>
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v4.view.ViewPager
android:id="@+id/viewpagerdispatchtoken"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/white">
android:background="@color/white">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/framelayout1"></FrameLayout>
</android.support.v4.view.ViewPager>
</android.support.design.widget.CoordinatorLayout>
</LinearLayout>
希望这会帮助你... :)
