This is my code I want to set custom tab like when i select the first tab then indicator and tab width or weight of the first tab I should increase and second tab decrease show only image not text same if we select the second tab then first tab indicator or weight should decrease and second tab text and image should visibility on:
my current Screen:
in this u can see that tab one is selected image and text are visible tab second is not unselected so the only image is visible no text:
but my Expected tab is like this :
look in this when we select tab then indicator and width of tab increase and tab 2 decreases please suggest me how I will achieve this .thanx

you can easily achieve custom tab with tab layout,
try this one:
public void setupTabView(){
for (int i = 0; i < tabLayout.getTabCount(); i++) {
tabLayout.getTabAt(i).setCustomView(R.layout.custom_tab);
TextView tab_name = (TextView) tabLayout.getTabAt(i).getCustomView().findViewById(R.id.txt_tab_name);
tab_name.setText("" + tabNames[i]);
}
}
And make one drawable file with name custom_tab:
<?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="wrap_content">
<TextView
android:id="#+id/txt_tab_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:textSize="14sp" />
</RelativeLayout>

Use Below Code .It is have two option.
(i) Create custom TabLayout
(ii) Change custom tablayout text color
(i) Custom TabLayout
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/tab"
android:layout_width="match_parent"
android:textSize="15sp"
android:gravity="center"
android:textColor="#color/txtbox_text_color_darek"
android:layout_height="match_parent"
/>
Source code is:
TextView tabOne = (TextView)
LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabOne.setText("KPIs" + " ");
tabOne.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.alert_gray,
0);
Objects.requireNonNull(tabLayout.getTabAt(4)).setCustomView(tabOne);
(II) Change Color
private void custom_tablayout_select_unselected_four(final TextView tabOne) {
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
if (Objects.requireNonNull(tabLayout.getTabAt(4)).isSelected()) {
tabOne.setTextColor(getResources().getColor(R.color.text_color_darkblue));
} else {
tabOne.setTextColor(getResources().getColor(R.color.txtbox_text_color_darek));
}
}
#Override`
public void onTabUnselected(TabLayout.Tab tab) {
// tabOne.setTextColor(Color.GREEN);
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
// tabOne.setTextColor(Color.GREEN);
}
});
}

I copied the solution from here, Maybe it will be useful for you
Display display = getWindowManager().getDefaultDisplay();
int width = display.getWidth();
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
TabHost mTabHost = getTabHost();
mTabHost.addTab(mTabHost.newTabSpec("tab_test1")
.setIndicator((""),getResources().getDrawable(R.drawable.mzl_05))
.setContent(new Intent(this, NearBy.class)));
mTabHost.addTab(mTabHost.newTabSpec("tab_test2")
.setIndicator((""),getResources().getDrawable(R.drawable.mzl_08))
.setContent(new Intent(this, SearchBy.class)));
mTabHost.setCurrentTab(0);
mTabHost.getTabWidget().getChildAt(0).setLayoutParams(new
LinearLayout.LayoutParams((width/2)-2,50));
mTabHost.getTabWidget().getChildAt(1).setLayoutParams(new
LinearLayout.LayoutParams((width/2)-2,50));
You can try another code tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 50;

Create Custom tab layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
tabTitles = new String[]{getString(R.string.main_tab_call), getString(R.string.main_tab_chat), getString(R.string.main_tab_contact)};
private void setupTabIcons() {
for (int i = 0; i < tabTitles.length; i++) {
mTabLayout.getTabAt(i).setCustomView(prepareTabView(i));
}
}
private View prepareTabView(int pos) {
View view = getLayoutInflater().inflate(R.layout.custom_tab, null);
TextView tv_title = view.findViewById(R.id.tv_title);
TextView tv_count = view.findViewById(R.id.tv_count);
tv_title.setText(tabTitles[pos]);
return view;
}

ViewPager Text Onclick

I am currently doing this android tutorial https://www.androidhive.info/2016/05/android-build-intro-slider-app/ .

After this line in your adapter :
View v = inflater.inflate(layouts[position],container,false);
Add:
TextView tv =(TextView) v.findViewById(R.id.yourTextView);
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Do your stuff here whatever you want to do upon click
}});

public class IntroFragment_1 extends Fragment {
private String title;
private int page;

fragmentFirst.setArguments(args);
return fragmentFirst;
}
// Store instance variables based on arguments passed
#Override
public void onCreate(Bundle savedInstanceState) {

page = getArguments().getInt("someInt", 0);
title = getArguments().getString("someTitle");
}

intro_images_1.startAnimation(xmlAnimationSample);
return view;
}
}
MyViewPagerAdapter

Android click on view above the view

I have tab Layout with dynamically added custom tabs (Image View + Text View)
I want to change image on select tab and on reselect (2 kind of images)
But there is no click event listeners on Tab, so I added transparent layout to catch clicks.
How do I need to change settings, to make 4 Linear Layouts clickable?
The code:
<RelativeLayout
android:id="#+id/layout_sort_bar_fc"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentBottom="true">
<android.support.design.widget.TabLayout
android:id="#+id/sort_bar_fc"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
app:tabMaxWidth="0dp"

android:orientation="horizontal"></LinearLayout>
</LinearLayout>
</RelativeLayout>

the following answer deals with somewhat the same question and the answer marked as solution is what you're looking for, it explains how to define and use selectors

Well, you can change image on a selected tab by two method which you need to create in Custom Pager Adapter and call it from tab selected listener.
"MainActivity"
public class MainActivity extends AppCompatActivity {
TabLayout tabLayout;
ViewPager viewPager;
ViewPagerAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

viewPager = (ViewPager) findViewById(R.id.viewpager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
createViewPager(viewPager);
tabLayout.setupWithViewPager(viewPager);
createTabIcons();
adapter.SetOnSelectView(tabLayout,0);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
int c = tab.getPosition();
adapter.SetOnSelectView(tabLayout,c);
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
int c = tab.getPosition();
adapter.SetUnSelectView(tabLayout,c);
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
for (int i = 0; i < tabLayout.getTabCount() - 1; i++) {

p.setMargins(0, 0, 10, 0);
tab.requestLayout();
}
}

Using above code I am getting tab text below the icon(i mean in two different line).THe next issue is I have set the margin but I dont know how to set the color of margin.The final issue is I want to change the background color of active tab to yellow as shown in image.Please help me fix this issue

try this
private void setupTabIcons() {
LayoutInflater inflater = LayoutInflater.from(this);
View view1 = inflater.inflate(R.layout.custom_view, null, false);
((TextView) view1.findViewById(R.id.text)).setText("Tab1");
((ImageView) view1.findViewById(R.id.image)).setImageResource(tabIcon[0]);
View view2 = inflater.inflate(R.layout.custom_view, null, false);
((TextView) view2.findViewById(R.id.text)).setText("Tab2");
((ImageView) view2.findViewById(R.id.image)).setImageResource(tabIcon[0]);
View view3 = inflater.inflate(R.layout.custom_view, null, false);
((TextView) view3.findViewById(R.id.text)).setText("Tab3");
((ImageView) view3.findViewById(R.id.image)).setImageResource(tabIcon[0]);
tabLayout.getTabAt(0).setCustomView(view1);
tabLayout.getTabAt(1).setCustomView(view2);
tabLayout.getTabAt(2).setCustomView(view3);
your custom view will look like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="wrap_content" />
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

You can Use android:drawableLeft to display drawable on left of
textview properly.
For Different backgroundColor for Different state You can use
android:background for different color state like this

Android : How to make a tab not selectable/swipable as per radiobutton click

In my android activity I have a radio button group and a tab layout using viewpager.
There are two tabs and 2 radio buttons.
The first tab is an attachment tab
second one is an event tab.
When i checked the first radio button then user is not allowed to see the first tab,so i need to disable the first tab and shows the second tab for the user.If i selected the second radio button i need to enable the first tab and user is allowed to access the first tab.I don't want to remove the tab,i just want to disable it so that user can't access it by swiping or clicking on the tab.
How to do that? Below is my code to show tab.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.create_asset);
//remaining code
viewPager2 = (ViewPager) findViewById(R.id.viewPager2);
setupViewPager2(viewPager2);
tabLayout2 = (TabLayout) findViewById(R.id.tab_layout2);
tabLayout2.setupWithViewPager(viewPager2);//setting tab over viewpager
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
}
});
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
//Implementing tab selected listener over tablayout
tabLayout2.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager2.setCurrentItem(tab.getPosition());//setting current selected item over viewpager
switch (tab.getPosition()) {
case 0:
Log.e("TAG","TAB1");
break;
case 1:
Log.e("TAG","TAB2");
break;
}
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
//Setting View Pager
private void setupViewPager2(ViewPager viewPager) {
expAttList = new ArrayList<COAAccount>();
adapter2 = new ViewPagerAdapter(getSupportFragmentManager());
adapter2.addFrag(new AttachmentFragment("Attachments",expAttList,fontFamily), "Attachments");
adapter2.addFrag(new EventFragment("Events",fontFamily), "Events");
viewPager2.setAdapter(adapter2);
}
//View Pager fragments setting adapter class
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();//fragment arraylist
private final List<String> mFragmentTitleList = new ArrayList<>();//title arraylist
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
//adding fragments and title method
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);

It's a tricky one.You need to use a custom ViewPager for this.Below is the code.
Change your ViewPager in xml to this :
<yourPackage.NonSwipeableViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_below="#id/tab_layout"/>
Below is the custom view pager class :
public class NonSwipeableViewPager extends ViewPager {
private boolean enabled;
public NonSwipeableViewPager(Context context) {
super(context);
this.enabled = true;
}
public NonSwipeableViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
this.enabled = true;
}
#Override
public boolean onInterceptTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onInterceptTouchEvent(event);
}
return false;
}
#Override
public boolean onTouchEvent(MotionEvent event) {
if (this.enabled) {
return super.onTouchEvent(event);
}
return false;
}
public void setPagingEnabled(boolean enabled) {
this.enabled = enabled;
}
}
Now in your activity use below code :
NonSwipeableViewPager viewPager = (NonSwipeableViewPager) findViewById(R.id.pager);
//write code to set viewpager to the tablayout that u have already done.Use the same.
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
pos = rdbGroup.indexOfChild(findViewById(checkedId));
LinearLayout tabStrip = ((LinearLayout)tabLayout.getChildAt(0));
switch (pos) {
case 0:
viewPager.setCurrentItem(1);
viewPager.setPagingEnabled(false);
tabstrip.getChildAt(0).setClickable(false);
tabstrip.getChildAt(0).setEnabled(false);
break;
case 1:
viewPager.setCurrentItem(0);
viewPager.setPagingEnabled(true);
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
break;
default:
//here add whatever you like
break;
}
}
});
Use the swicth condition as per your requirement.

You can try this:
ViewPager viewPager2;
TabLayout tabLayout2;
ViewPagerAdapter adapter2;
RadioGroup rdbGroup;
RadioButton rdb1, rdb2;
LinearLayout tabstrip;
int pos;
#Override
protected void onCreate(Bundle savedInstanceState) {

//remaining code
viewPager2 = (ViewPager) findViewById(R.id.viewPager2);
setupViewPager2(viewPager2);
tabLayout2 = (TabLayout) findViewById(R.id.tab_layout2);
rdbGroup = (RadioGroup) findViewById(R.id.rdbGroup);
rdb1 = (RadioButton) findViewById(R.id.rdb1);
rdb2 = (RadioButton) findViewById(R.id.rdb2);
tabLayout2.setupWithViewPager(viewPager2);//setting tab over viewpager
//get position of already checked radiobutton
int radioButtonID = rdbGroup.getCheckedRadioButtonId();
View radioButton = rdbGroup.findViewById(radioButtonID);
pos = rdbGroup.indexOfChild(radioButton);
tabstrip = (LinearLayout) tabLayout2.getChildAt(0);
//check which radiobutton is already checked and as per its pos disbale or enable the tabs as below
if (pos == 0) {
tabLayout2.getTabAt(1).select();
tabstrip.getChildAt(0).setClickable(false);
tabstrip.getChildAt(0).setEnabled(false);
} else if (pos == 1) {
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
}
rdbGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(RadioGroup group, int checkedId) {
pos = rdbGroup.indexOfChild(findViewById(checkedId));
switch (pos) {
case 0:
tabstrip.getChildAt(0).setClickable(false);
tabstrip.getChildAt(0).setEnabled(false);
break;
case 1:
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
break;
default:
//here add whatever you like
tabstrip.getChildAt(0).setClickable(true);
tabstrip.getChildAt(0).setEnabled(true);
break;
}
}
});
//Implementing tab selected listener over tablayout
tabLayout2.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager2.setCurrentItem(tab.getPosition());//setting current selected item over viewpager
switch (tab.getPosition()) {
case 0:

break;
}
}
#Override

});
}
