I want an example of tab like this
I searched but just got this.
I couldn't use this source. Can someone tell me another example of tab with sliding option.
I think the viewpageindicator is not the same as google plays tabs.
cause when i'm scrolling in google plays page the line below tabs moves while scrolling, But in viewpageindicator it's not.
Thank you
This article (Android Material Design working with Tabs) published on September 13, 2015 guides you through creating tab pages.
For example, creating Fixed Tabs
Fixed tabs should be used when you have limited number of tabs. These tabs are fixed in position. In android design support library lot of new elements like
CoordinatorLayout
,AppBarLayout
,TabLayout
and lot more were introduced. I won’t cover all of these as it’s not the agenda of this article.Open the layout file of main activity (
activity_main.xml
) and add below layout code.
app:tabMode
– Defines the mode of the tab layout. In our case the value should be “fixed”activity_main.xml
<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="match_parent"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:layout_scrollFlags="scroll|enterAlways" app:popupTheme="@style/ThemeOverlay.AppCompat.Light" /> <android.support.design.widget.TabLayout android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" app:tabMode="fixed" app:tabGravity="fill"/> </android.support.design.widget.AppBarLayout> <android.support.v4.view.ViewPager android:id="@+id/viewpager" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior" /> </android.support.design.widget.CoordinatorLayout>
Open
MainActivity.java
and do the below changes.
tabLayout.setupWithViewPager()
– Assigns the ViewPager to TabLayout.
setupViewPager()
– Defines the number of tabs by setting appropriate fragment and tab name.ViewPagerAdapter – Custom adapter class provides fragments required for the view pager. MainActivity.java
package info.androidhive.materialtabs.activity; import android.os.Bundle; import android.support.design.widget.TabLayout; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; import java.util.ArrayList; import java.util.List; import info.androidhive.materialtabs.R; import info.androidhive.materialtabs.fragments.OneFragment; import info.androidhive.materialtabs.fragments.ThreeFragment; import info.androidhive.materialtabs.fragments.TwoFragment; public class MainActivity extends AppCompatActivity { private Toolbar toolbar; private TabLayout tabLayout; private ViewPager viewPager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(true); viewPager = (ViewPager) findViewById(R.id.viewpager); setupViewPager(viewPager); tabLayout = (TabLayout) findViewById(R.id.tabs); 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) { 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); } } }
Now run the app. You should able to see the tabs displayed with swipe functionality between the tabs.
First you need to create an xml layout file with viewpager android.support.v4.view.ViewPager
Then inflate this layout in your main activity, make sure your activity implements
android.support.v7.app.ActionBar.TabListener
Lets say, you want to have 4 tabs, then create
4 different fragments. Create a common adapter to facilitate these fragments based on the
tabs you select.
Here is the simple example with code snippet, http://www.feelzdroid.com/2014/10/android-action-bar-tabs-swipe-views.html
Note: above example works well with android support lib, which provides backward actionbar
compatibility for earlier version of android phones
Hope it helps.
Thanks
When I had implemented something similar, I had done it in a nicer way, in the sense of classes. I had created the adapter in a package called working.
Below is the code:
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int index) {
switch (index) {
case 0:
return new WorkingFragment();
//You can add as many fragments as you wish here by adding the cases and calling the different fragments.
}
return null;
}
@Override
public int getCount() {
// get item count - equal to number of tabs. 4 is only the number of fragments I had used.
return 4;
}
}
You then need to create a new class called WorkingFragment
in the example I am giving. For the sake of clean coding, I created this class in the main package.
Below is the code for the fragment:
public class NewEventFragment extends Fragment {
View rootView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//reference the xml file containing the view with all the code here.
}
}
In the MainActivity
, you then need to make the functionality to change form one tab to another. In my case I had included this in the main package.
Below is the code for the MainActivity class:
public class MainActivity extends FragmentActivity implements ActionBar.TabListener {
private ViewPager ViewPager;
private TabsPagerAdapter SectionsPagerAdapter;
private ActionBar actionBar;
//Include the name for the tabs in this array. Make sure the number of elements in this string matches the number of views you will have in your app.
private String[] tabs = {};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialisation
ViewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
SectionsPagerAdapter = new TabsPagerAdapter(getSupportFragmentManager());
ViewPager.setAdapter(SectionsPagerAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
}
ViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
@Override
public void onTabReselected(Tab tab, android.app.FragmentTransaction ft) {
}
@Override
public void onTabSelected(Tab tab, android.app.FragmentTransaction ft) {
ViewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(Tab tab, android.app.FragmentTransaction ft) {
}
}
Hope this has helped you achieve the necessary funtionality for your app :)
simple way to work with fragment tabs
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
in on create and then
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new
ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new RootDetailFragment(), "TAB 1");
adapter.addFrag(new ShiftDetailFragment(), "TAB 2");
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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
in layout file add
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000"
app:tabGravity="fill"
app:tabMode="fixed" />
</android.support.design.widget.AppBarLayout>
