Android Fragments not showing up Text view and internal elements

I am new to android.I created a tablayout and a viewpager with two fragments.I have elements/items in my created Detail Fragment and a TextView in my measure fragment but when i run the code on my mobile,nothing is shown in my fragment.I haven't java code of my fragment.Everything works fine on the tablayout..i can switch between the tab but nothing is being shown in my fragments...why is that happening?
My Activity:

Try this one:
public class FriendshipParentFragment extends Fragment {
#BindView(R.id.tabs)
TabLayout tabs;
#BindView(R.id.viewpager)
ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_friendship_parent, container, false);
ButterKnife.bind(this, view);
initTabs();
return view;
}
private void initTabs(){
viewPager.setAdapter(new TabsAdapter(getChildFragmentManager()));
tabs.setupWithViewPager(viewPager);
tabs.getTabAt(0).setText("Tab1");
tabs.getTabAt(1).setText("Tab2");
tabs.setTabTextColors(ContextCompat.getColor(getActivity(), R.color.colorAccent), ContextCompat.getColor(getActivity(), R.color.colorBottomNavigationPrimary));
tabs.setSelectedTabIndicatorColor(ContextCompat.getColor(getActivity(), R.color.white));
tabs.setSelectedTabIndicatorHeight(4);
}
public class TabsAdapter extends FragmentPagerAdapter {
public TabsAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0:
return new FollowersFragment();

return null;

is it possible to set transparent for viewpager of android

I want to make transparent for ViewPager, but I can't find any way to get it (It always has WHITE color, not transparent)
My layout: main_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/wallpaper">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:background="#00ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
</LinearLayout>
The layout for first fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#00ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="AAAAAAAAAAAAAAAA"
android:id="#+id/textView"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
And the layout for second fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#00ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
I already set transparent for both background of ViewPager and layouts for fragments. But it's always WHITE.
So, Is it possible to set transparent for ViewPager? Can you explain it for me (if any). Any suggestion will be appreciate. Thank you.
EDIT:
I used the default theme for activity:
Screenshot:

Awais Soomro answer didn't work, so I've come up with this:
Fragment.java
#Override
public void onStart() {
super.onStart();
getView().setBackgroundColor(Color.TRANSPARENT);
}
or even...
#Override
public void onViewCreated(final View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
view.setBackgroundColor(Color.TRANSPARENT);
}
});

Here's the code to this:
MyFragment.java:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class MyFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.my_fragment, container, false);
}
}
my_fragment.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#00ffffff"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="AAAAAAAAAAAAAAAA"
android:textColor="#69f0ae"
android:id="#+id/textView"
android:layout_gravity="center_horizontal"/>
</LinearLayout>
Main.java:
FragmentPagerAdapter mPagerAdapter = new FragmentPagerAdapter(getSupportFragmentManager()) {
#Override
public Fragment getItem(int position) {
return new MyFragment();
}
#Override
public int getCount() {
return 1;
}
};
ViewPager mViewPager = (ViewPager) findViewById(R.id.view_pager);
mViewPager.setAdapter(mPagerAdapter);
main_activity.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/wallpaper">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager"
android:background="#00000000"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
</android.support.constraint.ConstraintLayout>

The problem is probably not the background color of the ViewPager. It's probably the view that's inflated by the adapter that ViewPager is using. Change the background color of that view.

Add image on 3 tabs

How can I add images into tab ? Currently I'm able to move the tab to bottom but have no idea on how to change the LL Tab1, LL Tab2, LL Tab3 to icon.Am I on the right path ? Any help would be greatly appreciated.

Anyone can help? Thanks a lot !

Try using TabLayout from Android Design Support Library to meet material design guidelines for tabs.
The Design library’s TabLayout implements both fixed tabs, where the
view’s width is divided equally between all of the tabs, as well as
scrollable tabs, where the tabs are not a uniform size and can scroll
horizontally.
To implement TabLayout check this guide and how to add the icon for swipeable tabs to set icons to tabs using setIcon.
final int[] ICONS = new int[]{
R.drawable.ic_action_document,
R.drawable.ic_action_tick,
R.drawable.ic_action_trash};
....
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);
tabLayout.getTabAt(0).setIcon(ICONS[0]);
tabLayout.getTabAt(1).setIcon(ICONS[1]);
tabLayout.getTabAt(2).setIcon(ICONS[2]);
To set the tabs at the bottom in a TabLayout check - How can I set tabs at the bottom and also hide top actionbar? where you put the TabLayout in a relativeLayout and align it to parent bottom:
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
app:tabMode="fixed"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="6dp"
app:tabTextColor="#d3d3d3"
app:tabSelectedTextColor="#ffffff"
app:tabIndicatorColor="#ff00ff"
android:minHeight="?attr/actionBarSize"
android:layout_alignParentBottom="true"
/>
Although you can put your tab layout at the bottom, try not to use bottom tab bars if possible as per the Pure Android guide.
Other platforms use the bottom tab bar to switch between the app's
views. Per platform convention, Android's tabs for view control are
shown in action bars at the top of the screen instead.

You can create third fragment class, and layout as i have done above.
Run it. Hope this would work

Try this,
puth this activity_main.xml and set the custom height to TabLayout.
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="#dimen/custom_tab_layout_height"
app:tabMode="fixed"
app:tabGravity="fill"/>
Create an xml layout named custom_tab.xml under res ⇒ layout. In this layout we have defined the custom view for the tab.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tab"
android:textColor="#color/colorAccent"
android:textSize="#dimen/tab_label"
android:fontFamily="#string/font_fontFamily_medium"/>
Open MainActivity.java and modify the code as below. Here if you observe setupTabIcons() method, I have rendered custom_tab.xml layout in each tab using below lines of code.
TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabOne.setText("ONE");
tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_favourite, 0, 0);
tabLayout.getTabAt(0).setCustomView(tabOne);
TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabTwo.setText("TWO");
tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_call, 0, 0);
tabLayout.getTabAt(1).setCustomView(tabTwo);
TextView tabThree = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tabThree.setText("THREE");
tabThree.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_tab_contacts, 0, 0);
tabLayout.getTabAt(2).setCustomView(tabThree);

Try this,Really interesting.Must be the solution

Well you can either place an ImageView in your Linearlayout that is each tab, or you can set an drawable as a background for your LinearLayout. If your image will act a background then you will obviously want to add that image as a background and not add an ImageView as a child to your LinearLayout. If it is going to be content though, not a background, you should add an ImageView to each LinearLayout like you would add a child of any other type to a parent View.

Inflating Custom TabLayout with many functionalities inside a fragment using PagerSlidingTabStrip

Here I'm implementing TabLayout with viewPager in a Fragment using library of com.astuetz.PagerSlidingTabStrip. Everything is fine but now I want to add custom Tab and some more functionalities.

Get button from a fragment in Android

I was working with and slider tab, insaid the main view I have 2 tabs and insaid them, I have a XML to set the UI. Everything is perfect, I get my slide tabs and I can run the app. The problem is when I try to get a button from my fragments. I was reading about LayoutInflater, but I couldn´t solved.
Please, I think I don´t undestand very well how the fragment works and I would like a little of help about this.
This is my main activity (onCreate):
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebookLogin = new FacebookLogin(getApplicationContext());
setContentView(R.layout.register_tabs);
toolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolBar);
adapter = new ViewPagerAdapter(getSupportFragmentManager(),Titles,Numboftabs);
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
tabs = (SlidingTabLayout) findViewById(R.id.tabs);
tabs.setDistributeEvenly(true);
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.colorPrimary);
}
});
tabs.setViewPager(pager);
}
I my main XML:
<LinearLayout

The class of the fragment:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.facebook.login.widget.LoginButton;
public class RegisterTabLogin extends Fragment {
private LoginButton loginButton;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, #Nullable Bundle savedInstanceState) {
View v =inflater.inflate(R.layout.register_tab_login,container,false);
return v;
}
}
As I say, I just want to get a View from the fragment and work with it in the Main Activity, I was reading about LayoutInflater but I could´t solved, Also I read some questions here, (Using button from a fragment in main activity) but I couldn´t solved.
Any help will be gratefull, a link o something.

have you tried this?
public class RegisterTabLogin extends Fragment {
private LoginButton loginButton;
private LoginCallback mCallback;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, #Nullable Bundle savedInstanceState) {
View v =inflater.inflate(R.layout.register_tab_login,container,false);
loginButton = (LoginButton) v.findViewById(R.id.login_button);
showData.setOnClickListener(onClickListener);
return v;
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
try {
mCallback = (LoginCallback) activity;
} catch (ClassCastException e) {
throw new ClassCastException(
"Activity must implement LoginCallback.");
}
}
private final OnClickListener onClickListener = new OnClickListener() {
#Override
public void onClick(View v) {
if (mCallback != null) {
mCallback.onLogin();
}
}
};
public static interface LoginCallback{
void onLogin();
}
}
then on MainActivity
public class MainActivity extends Activity implements
RegisterTabLogin.LoginCallback {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebookLogin = new FacebookLogin(getApplicationContext());
setContentView(R.layout.register_tabs);
toolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolBar);
adapter = new ViewPagerAdapter(getSupportFragmentManager(),Titles,Numboftabs);
pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(adapter);
tabs = (SlidingTabLayout) findViewById(R.id.tabs);
tabs.setDistributeEvenly(true);
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
#Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.colorPrimary);
}
});
tabs.setViewPager(pager);
}
#Override
public void onLogin() {
//DO SOMETHING
}
}

In your Main Activity, access this view in the OnStart() method like this:
#Override
protected void onStart() {
Button yourButton = (Button)findViewById(R.id.yourButton);
super.onStart();
}
EDIT:
Your fragment should be present in your Main Activity.
You can add RegisterTabLogin in a certain containerView present in your Main Activity layout in the OnCreate() method like this:
RegisterTabLogin registerTabLogin= new RegisterTabLogin();
getFragmentManager().beginTransaction().add(R.id.a_certain_layout, registerTabLogin).commit();
