Hi I make an swipe tab app, it works whena i swipe the screen , but i don't see the tabs part. How can i resolve it?
Can you help me.
Thanks
Here is my XML layout
<RelativeLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include

android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/viewpager">
</android.support.v4.view.ViewPager>
</RelativeLayout>
Here is my MainActivity file
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
TabLayout tabLayout;
ViewPager viewPager;
ViewPagerAdapter viewPagerAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar= (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
tabLayout= (TabLayout) findViewById(R.id.tablayout);
viewPager= (ViewPager) findViewById(R.id.viewpager);
viewPagerAdapter=new ViewPagerAdapter(getSupportFragmentManager());
viewPagerAdapter.addFragments(new Home(),"Home");
viewPagerAdapter.addFragments(new Top(),"Top");
viewPagerAdapter.addFragments(new Buttom(),"Buttom");
viewPager.setAdapter(viewPagerAdapter);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setTabsFromPagerAdapter(viewPagerAdapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
}
}
And this is my adapters part:
public class ViewPagerAdapter extends FragmentStatePagerAdapter {
private ArrayList<Fragment> fragments= new ArrayList<>();
private ArrayList<String> tabTitles = new ArrayList<>();
public void addFragments(Fragment fragments, String titles){
this.fragments.add(fragments);
this.tabTitles.add(titles);
}
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
return fragments.get(position);
}
#Override
public int getCount() {
return fragments.size();
}
#Override
public CharSequence getPageTitle(int position) {
return tabTitles.get(position);
// return "Tab" + position;
}
}
i can't see the reason why my tabs don't available.
I added compile 'com.android.support:design:25.3.1' into my grandle.app file
Try this:
Add an id to the appbarlayout like this:
android:id="#+id/appbar"
And add this to the tabs:
android:layout_below="#+id/appbar"

P.S. TwoFragment.java and ThreeFragment.java are same as OneFragment.java
I have a activity that contain 2 fragments and both the fragments containing a recyclerview.
I need to implement a swipe gesture (when i swipe from one side to another the fragments need to be changed).
Previously i have added swipe gesture, but when i swipe the recycler view will scroll instead of change of fragments.
Can you help in implementing this..
Thanks
Use TabLayout with ViewPager. Create two tabs for two fragments in the activity .
http://www.androidhive.info/2015/09/android-material-design-working-with-tabs/
just use Android TabLayout with ViewPager and your problem will be solved :)
This is how you can do it:
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);
}
}
}
And this is the .XML file:
<?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:layout_width="match_parent"
android:layout_height="wrap_content"

android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"

</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"

android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Hope it helps!
Simply use Tablayout and ViewPager
Here the code :-
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;
}
}
}
Here the 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>
Hope this will help you... :)
I am attaching the java code and its xml and the screenshot.
the tablayout.java is the class where I am attaching the tablaout.xml , and when I am aligning the tablayout at the bottom of the screen , some of the space at the top of the layout gets wasted.
TabLayout.java
public class Bottom_Tabs_Activity extends AppCompatActivity {
private TabLayout tabLayout;
private ViewPager viewPager;
private int[] tabIcons = {
R.drawable.ic_friends,
R.drawable.ic_map,
R.drawable.ic_status,
R.drawable.ic_chat,
R.drawable.ic_profile
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs);
viewPager = (ViewPager) findViewById(R.id.viewpager);
if (viewPager != null)
setupViewPager(viewPager);
else {
Log.e("test", "i am null");
}
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
setupTabIcons();
}
private void setupTabIcons() {
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
tabLayout.getTabAt(3).setIcon(tabIcons[3]);
tabLayout.getTabAt(4).setIcon(tabIcons[4]);
}
private void setupViewPager(ViewPager viewPager)
{
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new MapFragment(),"MAPS");
adapter.addFrag(new PeopleFragment(),"PEOPLE");
adapter.addFrag(new HomeFragment(),"HOME");
adapter.addFrag(new ChatFragment(),"CHAT");
adapter.addFrag(new ProfileFragment(),"PROFILE");
viewPager.setAdapter(adapter);
}

}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
// return null to display only the icon
return null;
}
}
}

SCREENSHOT
the empty space is your action bar,you will have to give it a separate layout and attach the required maps and people in that layout.
write this code below setContentView of your activity and edit it as you desire.
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.black)));
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.action_bar);
EditText s= (EditText) getSupportActionBar().getCustomView().findViewById(R.id.centertext2);
s.setText("New Role");
Or if you want to remove the action bar
getSupportActionBar().hide();
Hope this helps you.
This should be simple but I can't wrap my head around it.
I am setting up TabLayout with setupViewViewPager such that I have 3 tabs (Home, Tab1, Tab2). How do I set it so that when I click on a link in Tab1, a new fragment replaces the existing fragment?
Your XML layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0">
<include layout="#layout/toolbar" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="50dip"
android:gravity="bottom"
app:tabGravity="center"
app:tabIndicatorColor="#android:color/white"
app:tabMode="scrollable"
app:tabPaddingStart="20dp" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
</LinearLayout>
Your java code
public class ClassName extends AppCompatActivity {
private ViewPager viewPager;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.xml_file_name);
init();
}
private void init() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
viewPager = (ViewPager) findViewById(R.id.viewpager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
setSupportActionBar(toolbar);
setupViewPager();
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager() {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new FragmentName1(),"Home");
adapter.addFragment(new FragmentName2(),"Tab1");
adapter.addFragment(new FragmentName3(),"Tab2");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
For reference, I solved my problem by creating a fragment for each tab, each containing a unique FrameLayout.
Next, I used my activity to add a fragment to the FrameLayout (depending on which tab is selected) with FragmentTransaction.
I'm not sure if this is the best solution, but it did work for me.
i have this Andriod swipe tabs working perfectly
Activity Layout

tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new OneFragment(), "ONE");
adapter.addFragment(new TwoFragment(), "TWO");
adapter.addFragment(new ThreeFragment(), "THREE");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {

}
#Override

mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
But each time i click on the tab headers it does not move to the respective tab,unless i swipe the tabs.Please how can i achieve the Movement of the tabs by tapping on their respective tab header/icon? thanks
Edit:
Copy/Pasted your code and it worked fine. If I tap on the Header it works like it should. Maybe some code in your Fragments messing around?
Deprecated:
Another way would be if you add them to the ActionBar. It seems that this method is now deprecated. But only minor changes would be required for that. See the official documentation
