In My Android Project I am using Material-design for tab view.
I have :
tab_activity.xml
<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"
/>
and java class file is:
public class SimpleTabsActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_activity);
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);
}
}
}
With this I am getting the tab view..
But , here How can I remove the arrow beside app name?
and, sliding tabs are working but when I click on any tab(tab1/tab2/tab3) click event is not working.why??
I think you should use this:
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter
(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_simple_tabs, menu);
return true;
}
add a PagerAdapter class ,add the fragments..
activity_main.xml
<RelativeLayout
android:id="#+id/main_layout"

android:layout_width="match_parent"

I think this should work..
just set clickable=true for TabLayout
<android.support.design.widget.TabLayout
android:id="#+id/tabs_home"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabPaddingStart="0dp"
app:tabPaddingEnd="0dp"
app:tabIndicatorHeight="3dp"
android:clickable="true"
app:tabMaxWidth="0dp"/>
I think that your issue here stems from trying to mix things into TabView when it actually isn't getting the hint of what you want viewed.
I suggest just using ActionBar if not actually using a sidebar menu for your main activity setup. Here I just have generic ones set up and you can load you fragment names in accordingly.
Inside of your MainActivity.xml
protected void onCreate(android.os.Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActionBar bar = getActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
Tab listTab = bar.newTab().setText(R.string.list_title);
Tab generalTab = bar.newTab().setText(R.string.generalsettings);
Tab faqtab = bar.newTab().setText(R.string.faq);
Tab abouttab = bar.newTab().setText(R.string.about);
listTab.setTabListener(new TabListener<ProfileList>("profiles", ProfileList.class));
generalTab.setTabListener(new TabListener<GeneralSettings>("settings", GeneralSettings.class));
faqtab.setTabListener(new TabListener<FaqFragment>("faq", FaqFragment.class));
abouttab.setTabListener(new TabListener<AboutFragment>("about", AboutFragment.class));
bar.addTab(listTab);
bar.addTab(generalTab);
bar.addTab(faqtab);
bar.addTab(abouttab);
if(SendDumpFragment.getLastestDump(this)!=null) {
Tab sendDump = bar.newTab().setText(R.string.crashdump);
sendDump.setTabListener(new TabListener<SendDumpFragment>("crashdump",SendDumpFragment.class));
bar.addTab(sendDump);
}
}
protected class TabListener<T extends Fragment> implements ActionBar.TabListener
{
private Fragment mFragment;
private String mTag;
private Class<T> mClass;
public TabListener(String tag, Class<T> clz) {
mTag = tag;
mClass = clz;
// Check to see if we already have a fragment for this tab, probably
// from a previously saved state. If so, deactivate it, because our
// initial state is that a tab isn't shown.
mFragment = getFragmentManager().findFragmentByTag(mTag);
if (mFragment != null && !mFragment.isDetached()) {
FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.detach(mFragment);
ft.commit();
}
}
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if (mFragment == null) {
mFragment = Fragment.instantiate(MainActivity.this, mClass.getName());
ft.add(android.R.id.content, mFragment, mTag);
} else {
ft.attach(mFragment);
}
}
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
if (mFragment != null) {
ft.detach(mFragment);
}
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

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

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"
I am working on an Android app, that would have 4 tabs with 4 fragments. I have run the app on my Android device. But the problem I am encountering is that, when I click on the first 2 tabs, it works fine, but when I open the 3rd and 4th tab, APP CRASHES IMMEDIATELY!
Initially, I thought there was a bug on the 3rd and 4th fragments, but I later discovered that this is not a 3rd or 4th fragment bug. I replaced the 1st and 2nd fragments with the 3rd and 4th fragment, and the 1st and 2nd fragments replaced with the 3rd and 4th fragments. And the same thing still happened!

Since you have 4 tabs, please try adding the following code under main_activity onCreate event and see would it solve your issue.
viewpager.setOffscreenPageLimit(4);
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 {

tabLayout.setupWithViewPager(viewPager);
setupTabIcons();

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?

adapter.addFragment(new FragmentName2(),"Tab1");

mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int 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

android:layout_width="match_parent"
android:layout_height="match_parent" />
And the Activity
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);
}
}
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
