Android TabsLayout tabs with ImageView

I we know we can set any TextView for TabsLayout tabs without any problem, but at this time i dont have problem for setting TextView for tabs, but i want to have Image on tabs instead of text, for using this custom views i have this method:
private void setupTabIcons() {
inflater = LayoutInflater.from(context);
timeline = inflater.inflate(R.layout.joined_cafe_webs, null);
TabLayout.Tab contentJoinedCafeWebsTab = tabsLayout.getTabAt(0);
Objects.requireNonNull(contentJoinedCafeWebsTab).setCustomView(timeline);
grid_list = inflater.inflate(R.layout.user_channels, null);
TabLayout.Tab grid_listTab = tabsLayout.getTabAt(1);
Objects.requireNonNull(grid_listTab).setCustomView(grid_list);
post_items_view_pager.setCurrentItem(1);
...
}
joined_cafe_webs layout:
<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/grid_feeds"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_gravity="center"
android:background="?attr/selectableItemBackgroundBorderless"
android:padding="5dp"
android:tint="#color/grey_40"
app:srcCompat="#drawable/ic_time_line_black_24dp" />
after compile and run project on phone, tabs are empty

And
Add Icons+Text to TabLayout
You can use following code :
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
private int[] tabIcons = {
R.drawable.ic_tab_favourite,
R.drawable.ic_tab_call,
R.drawable.ic_tab_contacts
};
#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);
setupTabIcons();
}
private void setupTabIcons() {
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new OneFragment(), "ONE");
adapter.addFrag(new TwoFragment(), "TWO");
adapter.addFrag(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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}

Add Icons to TabLayouts in Android Studio

I am trying to create a chat app for android based on chat21 sdk app on github, with chat21 demo app also in github and the thing is that I want to add Icons to TabLayouts and I am stuck there because I tried a couple times on my own and I just can't get it to work, so here is an image of how I want my chat tabs to look,
here is tab_activity.xml code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/windowBackground"
tools:context=".TabActivity">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:background="#color/colorPrimary"
android:layout_height="wrap_content"

I think you are looking for this:
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
private int[] tabIcons = {
R.drawable.ic_tab_favourite,
R.drawable.ic_tab_call,
R.drawable.ic_tab_contacts
};
#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);
setupTabIcons();
}
private void setupTabIcons() {
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new OneFragment(), "ONE");
adapter.addFrag(new TwoFragment(), "TWO");
adapter.addFrag(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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
(this is the result)
This is the code which adds the Images:
private void setupTabIcons() {
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
}
and if you want the exact same like in your picture take a look at this page:

I want to show tab bar icon left side of text

I want to show icon left side of the text but the problem is that the icon is showing above the text. it's taking much more space.
I want keep the icon left sode of the text(title) . what should i do?
The main activity is given below
java.class
public class Tabsadar extends AppCompatActivity {
ExpandableRelativeLayout
expandableLayout1,
expandableLayout2,
expandableLayout3,
expandableLayout4;
private Toolbar toolbar;
private TabLayout tabLayout;

viewPager.setAdapter(adapter);
}

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);
}
}
}'
i want something like that
in my case something happend like that
any solution?

Just use app:tabInlineLabel="true"
Like:-
<com.google.android.material.tabs.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabInlineLabel="true"
app:tabGravity="fill"/>

As per your requirement I'll suggest you to create a custom view for tabs.
custom_tab_view.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:orientation="horizontal">
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="#dimen/_6sdp"
android:background="#drawable/ic_menu_gallery"/>
<TextView
android:id="#+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginLeft="#dimen/_3sdp"
android:textColor="#drawable/tab_text_selector"
android:textSize="#dimen/_15sdp" />
</LinearLayout>
</RelativeLayout>
And this layout of custom tab with PagerAdapter as
//On Create
for (int i = 0; i < mPagerAdapter.getCount(); i++) {
View customView = mPagerAdapter.getCustomView(getActivity(), i);
mainTabLayout.getTabAt(i).setCustomView(customView);
}
//Pager Adapter
public static class ViewPagerAdapter extends SmartFragmentStatePagerAdapter {
private List<Map<String, Object>> maps = new ArrayList<>();
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
public View getCustomView(Context context, int pos) {
View mView = LayoutInflater.from(context).inflate(R.layout.custom_tab_view, null);
TextView mTextView = (TextView) mView.findViewById(R.id.textView);
ImageView imageView = (ImageView) mView.findViewById(R.id.imageView);
mTextView.setGravity(Gravity.CENTER);
mTextView.setTypeface(Typeface.createFromAsset(context.getAssets(),
"fonts/aller_regular.ttf"));
mTextView.setText(getPageTitle(pos));
return mView;
}
#Override
public void destroyItem(ViewGroup container, int position, Object object) {
super.destroyItem(container, position, object);
}
#Override
public CharSequence getPageTitle(int position) {
return fragments[position];
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new CompletedTaskFragment();
case 1:
return new PendingTaskFragment();
}
return null;
}
#Override
public int getCount() {
return 2;
}
}
Hope it'll help you.

How to create tabs & their associated Fragments dynamically?

I want to create n number of tabs dynamically, using Rest APIs, Since every tab is associated with there Fragments while swiping, can I create tabs + Fragments dynamically using the number of tabs given in JSON (Rest API) or I have to create all individually?

Yes, you can:
<android.support.design.widget.TabLayout
android:id="#+id/htab_tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:background="#color/colorDivider"
app:tabIndicatorColor="#android:color/white" />
<android.support.v4.view.ViewPager
android:id="#+id/htab_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
 
public class MainActivity extends AppCompatActivity {
private ViewPager viewPager;
private TabLayout tabLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager) findViewById(R.id.htab_viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.htab_tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
//jsonResArray get from web service
for (int i = 0; i < jsonResArray.size(); i++) {
adapter.addFrag(new NewFragment(jsonResArray.get(i)), jsonResArray.get(i).getName());
}
viewPager.setAdapter(adapter);
}
static 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);

i want to set Image in the Tabs using following code.

Use this to set icon in tab
tabLayout.setupWithViewPager(viewPager);
//You tab icons
private int[] icons = {
R.drawable.one,
R.drawable.two,
R.drawable.three
};
for (int i = 0; i < tabLayout.getTabCount(); i++) {
tabLayout.getTabAt(i).setIcon(icons[i]);
}
Also If you want only Icon then on Adapter pass pageTitle null
#Override
public CharSequence getPageTitle(int position) {
// return null to display only the icon
return null;
}
Use this for Selector. This Might Work
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/icon_on" android:state_selected="true"/>
<item android:drawable="#drawable/icon_off"/> <!-- default -->
</selector>

Set icon like this way..
mTabLayout.addTab(mTabLayout.newTab().setIcon(R.drawable.yourIcon));

To set both icon and text:
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
private int[] tabIcons = {
R.drawable.ic_tab_favourite,
R.drawable.ic_tab_call,
R.drawable.ic_tab_contacts
};
#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);
setupTabIcons();
}
private void setupTabIcons() {
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new OneFragment(), "ONE");
adapter.addFrag(new TwoFragment(), "TWO");
adapter.addFrag(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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
Setting only icon to tab is same as setting text and icon except the method getPageTitle() in ViewPagerAdapter class returns null instead of tab label.
Modify MainActivity.java and modify the getPageTitle() method as :
#Override
public CharSequence getPageTitle(int position) {
// return null to display only the icon
return null;
}
