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.

I noticed that onCreateView() of one of my fragments is never called and i dont know why.I need to be able to make changes in onResume() but thats is also never called.
Here is how I add the fragments.
public class LiveGameStats extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_live_game_stats);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.tab1, new Tab1Fragment()).commit();
}
FragmentTabHost mTabHost = (FragmentTabHost) findViewById(R.id.liveGameTabhost);
mTabHost.setup(LiveGameStats.this, getSupportFragmentManager(), R.id.liverealtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("You"),
LiveGameTab1Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Your Team"),
LiveGameTab2Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Your Enemies"),
LiveGameTab3Fragment.class, null);
}
Tab1Fragment
public class Tab1Fragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View V = inflater.inflate(R.layout.tab1, container, false);
Log.v("FRAGMENT","FragmentActivityCreateView");
return V;
}
And finnaly the xml passed under R.layout.tab1
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

<ImageButton

android:src="#drawable/waves"
android:background="#drawable/search_selector"
android:padding="40dp"
android:layout_height="200dp"
android:layout_width="200dp"
android:onClick="liveMatch"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
I think I might have created the fragments the wrong way. As you see it now they are created as the xml says but when I changed tabs, the content is "reseted".Any changed I placed in onCreateView() or onResume() is not called.
EDIT
I have tried to implement the method described in the 1st comment. After the implementation the tabs have the same content. Is like all the tabs have the same content. This time I posted all my classes and their associated XML.
public class LiveGameStats extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_live_game_stats);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab1Fragment()).commit();
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab2Fragment()).commit();
getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab3Fragment()).commit();
}
FragmentTabHost mTabHost = (FragmentTabHost) findViewById(R.id.liveGameTabhost);
mTabHost.setup(LiveGameStats.this, getSupportFragmentManager(), R.id.liverealtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("You"),
LiveGameTab1Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Your Team"),
LiveGameTab2Fragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Your Enemies"),
LiveGameTab3Fragment.class, null);
}
activity_live_game_stats.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I wont post the code from LiveGameTab2 and LiveGameTab3 since they are almost the same. I have also another activity that
Edit2
Seems its solved when i changed from getSupportFragmentManager().beginTransaction().add(R.id.liverealtabcontent, new LiveGameTab1Fragment()).commit(); to getSupportFragmentManager().beginTransaction().add(android.R.id.tabcontent, new LiveGameTab1Fragment()).commit();
The problem is this:
getSupportFragmentManager().beginTransaction().add(R.id.tab1, new Tab1Fragment()).commit();
In the first argument you have to pass a id to a container in the Activity layout where your fragment will be attached.
You are passing a entire layout R.id.tab1.
Add a container view in activity_live_game_stats xml file,
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".DeviceFragment" >
<FrameLayout
android:id="#+id/myContainer"
...(Other attrs)>
</FrameLayout>
</RelativeLayout>
and then
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.myContainer, new Tab1Fragment()).commit();
}
im trying to use setContentView to switch to a layout with a fragment inside it
but it crashes every time
what should i do?
this is my entire code:
(it must switch to fragment_layout when i click the button in the activity_main)
(fragmant_layout has a fragment and the layout for the frgment is te layout1)
(it crashs when i cick the button to switch)
main activity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void switchlayout(View view) {//when the button in clicked
setContentView(R.layout.fragment_layout);
}
}
the fragment class:
public class frgment extends Fragment {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.layout1,container,false);
}
}
activity_main.xml:

android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"

</LinearLayout>
Please consider the following points::
On your parent layout (activity_main.xml), inside the Relative layout, add another layout called FrameLayout.
On your fragment layout(fragment_layout.xml), remove the fragment and add the layouts of layout1.xml to fragment_layout.xml
On your fragment class (MyFragment), inflate the fragment_layout.xml to the container and return the view (class name should start with uppercase letter, so name it like MyFragment)
On Activity class, place the following code on onclick listener.
//onClick on OnClickListener
MyFragment fragment = new MyFragment();
getSupportFragmentManager().beginTransaction()
.add(R.id.frame_layout, fragment)
.commit();
Once the layout of an Activity has been set it can not be changed at a later time.
There are a number of ways you can achieve this from which the easiest would be to have a wrapper layout and then injecting the fragment inside it using the FragmentManager class.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".fragmenttest.MainActivity">
<FrameLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<Button
android:text="Button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="switchlayout"
android:layout_marginTop="74dp"
android:id="#+id/button" />
</RelativeLayout>
And then on your button click add your fragment.
getSupportFragmentManager().beginTransaction().add(R.id.wrapper, MyFragment.newInstance(), "FragTag").commit();
Remember that you have to take care of your button since it will still be visible on top of you fragment.
I am really fresher in fragment,this is the first time I try it.Here is what I met,I dont know how to fix that,please help me.This is my left_fragment.xml code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Button"/>
</LinearLayout>
This is my right_fragment.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00ff00">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:textSize="20sp"
android:text="This is right fragment"/>
</LinearLayout>
They looks in the preview is,Left:
right:
And this is the LeftFragment.class:
public class LeftFragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.left_fragment,container,false);
return view;
}
}
This is the RightFrament.class:
public class RightFrament extends Fragment{
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.right_fragment,container,false);
return view;
}
}
This is the layout file activity_main.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"
>
<fragment
android:id="#+id/left_fragment"
android:layout_width="0dp"
android:name="com.example.gaby.fragmenttest.LeftFragment"
android:layout_weight="1"
android:layout_height="match_parent" />
<fragment
android:id="#+id/right_fragment"
android:name="com.example.gaby.fragmenttest.RightFrament"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
</LinearLayout>
this layout file's preview is like this:
I find it odd,I open it in Genymotion nexus7,It seems right.that means the android studio layout preview went wrong,How to solve that?
In your activity_main.xml use the tools:layout="..." attribute.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
...
>
<fragment
android:id="#+id/left_fragment"
....
tools:layout="#layout/left_fragment"
/>
<fragment
android:id="#+id/right_fragment"
...
tools:layout="#layout/right_fragment"
/>
</LinearLayout>
I'm using this library for the fab implementation.
As you can see in this video, the fab position is changing when the fragment loads.
After debugging it, I found that the listview "setAdapter()" method causes the position change.
I don't have a clue why it's happening..
My layout:

public class LeagueListFragment extends MyFragment {

mListView.setDivider(new ColorDrawable(getResources().getColor(R.color.gray)));
mListView.setDividerHeight(2);
mListView.setAdapter(mAdapter);
mListView.setOnItemClickListener(this);
return view;
}
}
Margin changes in the runtime on pre-Lollipop because shadow mustn't be taken into account when margins are set.
Try to disable the shadow by :
fab:fab_shadow="false"
Fixing the issue is not expected for now.. (See makovkastar answer)
The graphical layout for a simple android.support.v4.app.FragmentTabHost never renders in either Eclipse or Android Studio.
The Console error I get is consistently:
Exception raised during rendering: No tab known for tag null
I'm using the most basic XML file:
<android.support.v4.app.FragmentTabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TabWidget
android:id="#android:id/tabs"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0"/>
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
but the same error occurs.
I just wanted to add more views above or below the tab widget and frame layout.
I don't care so much about seeing the tab content; I just want to see the rest of my layout - but the problem is that NO OTHER VIEWS are rendered when a android.support.v4.app.FragmentTabHost resides in the layout.
I've read and tried to resolve the issue from the answer to this post:
Android: Tabs at the bottom with FragmentTabHost
but I don't think that that is my problem; I'm not looking to put a TabWidget on the bottom.
Every other one of my XML files opens perfectly.
The same problem occurs in Android Studio:
I had the same rendering problem as well as compilation error. I fixed the problem by finding that I was not passing Fragment when i was creating Addtab. You must pass atleast one fragment on mTabHost.addTab. Below is the working code.
private FragmentTabHost mTabHost;
mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
mTabHost.setup(HomeActivity.this, getSupportFragmentManager(), android.R.id.tabcontent);
mTabHost.addTab(mTabHost.newTabSpec("home").setIndicator("Home"), HomeFragment.class, null);
mTabHost.addTab(mTabHost.newTabSpec("mysheets").setIndicator("MySheets"));
mTabHost.addTab(mTabHost.newTabSpec("bookmarks").setIndicator("Bookmarks"));
Not sure about the error you've got (sorry, I'm really busy right now so can't spend more time checking) but in general it seems that the FragmentTabHost from the support libs doesn't care about the xml at all. See my previous answer to another question:
FragmentTabHost with horizontal scroll
From Layout i am getting the same Error..so,I resolve that Problem by Code only...It's working fine..Please try this code
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTabHost;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

}
If U need to put fragmented tabs at bottom of screen ...
#fallow undermentioned --
Make your xml file like this ..
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- <RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"> android:layout_alignParentTop="true" -->
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" />
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dip"
android:layout_height="0dip"
android:layout_weight="0" />
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
Now if your concern is opening several fragments with in single fragmented tabs ...
#follow steps ::
Create a container fragment. This container fragment will be default for all of your's tabs content.
For every tab content replace fragment U need with this container.
For ex:- Just like you replace your bed with different bed sheets .. :)
Your container fragment class that will be used differently in different tabs ... "LearnContainerFragment.java "
public class LearnContainerFragment extends BaseContainerFragment {
private boolean mIsViewInited;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
Log.e("test", "tab 1 oncreateview");
return inflater.inflate(R.layout.container_fragment, null);
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);

# How to use Conatiner..
For every fragment U need will be replaced with id of this container fragment.
#last your BaseContainerFragment.java class --
public class BaseContainerFragment extends Fragment {
public void replaceFragment(Fragment fragment, boolean addToBackStack) {
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
if (addToBackStack) {
transaction.addToBackStack(null);
}
transaction.replace(R.id.container_framelayout, fragment);
transaction.commit();
getChildFragmentManager().executePendingTransactions();
}
public boolean popFragment() {
Log.e("test", "pop fragment: " + getChildFragmentManager().getBackStackEntryCount());
boolean isPop = false;
if (getChildFragmentManager().getBackStackEntryCount() > 0) {
isPop = true;
getChildFragmentManager().popBackStack();
}
return isPop;
}
}
Hope it helps.....
Cheers!
