FragmentTabHost: The specified child already has a parent

FragmentTabHost: The specified child already has a parent - android

I'm trying to have a FragmentTabHost and set custom views for tabs. The FragmentTabHost is inflated inside a Fragment. This is the Fragment code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_friends, container, false);
mTabHost = (FragmentTabHost) root.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(),android.R.id.tabcontent);
TabHost.TabSpec friends = mTabHost.newTabSpec(FriendsTabFragment.TAG);
View tab = inflater.inflate(R.layout.friends_fragment_custom_tab,null);
ImageView view = (ImageView) tab.findViewById(R.id.tab_icon);
view.setImageResource(R.drawable.categoria_amici);
friends.setIndicator(view);
mTabHost.addTab(friends, FriendsTabFragment.class, null);
return root;
}
And here's the layout:
<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" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:layout_marginBottom="-4dp"/>
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
This is the FriendsTabFragment inflating code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.fragment_friends_tab, container,false);
return root;
}
This is the custom view tab (R.layout.friends_fragment_custom_tab):
<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="#android:color/black">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/tab_icon"/>
</LinearLayout>
If I run the project with this configuration it crashes on mTabHost.addTab() method saying that the specified child already has a parent. If I remove the LinearLayout around the ImageView inside the custom view tab, it works! But I need some customizations so I need that LinearLayout there. What am I doing wrong?

Change your layout to this one:
<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:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:layout_marginBottom="-4dp"/>
<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>
and also change:
mTabHost.setup(getActivity(), getChildFragmentManager(),android.R.id.tabcontent);
friends.setIndicator(view);
to
mTabHost.setup(getActivity(), getChildFragmentManager(),R.id.realtabcontent);
friends.setIndicator(tab);

running 2 Webviews in a view

I'm unable to run two web views at once I've tried playing with it but need some help... its not as simple as saying View2 like in Swift.

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_feed, container, false);
}
#Override
public void onViewCreated(View view , Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
livestream = (WebView) view.findViewById(R.id.livestream);
livestream.setWebViewClient(new WebViewClient());
livestream.loadUrl("website1");
livefeed = (WebView) view.findViewById(R.id.livefeed);
livefeed.setWebViewClient(new WebViewClient());
livefeed.loadUrl("website2");
}
}
One view is a video stream other is the notes for the stream.

You need to make your layout scrollable and chnage the textview's height to wrap_content
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:background="#ffb067"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:textColor="#android:color/white"
android:textSize="20sp"
android:textStyle="bold"
android:text="Feed Fragment" />
<WebView
android:id="#+id/livefeed"
android:layout_width="match_parent"
android:layout_height="310dp"
android:layout_marginTop="20dp" />
<WebView
android:id="#+id/livestream"
android:layout_width="match_parent"
android:layout_height="200dp" >

I strongly recommend that you read Google's a layout .

findViewById sometimes returns null in fragment

findViewById is returning null when searching for an ImageView inside a fragment, but not for a TextView.
Here is my code:

fragment.java (not all):
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment, container, false);
return view;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
//Get Views
txt_container = (TextView) view.findViewById(R.id.txt_2);
img_view = (ImageView) view.findViewById(R.id.2_imag);
}
The strange thing is that the txt_2 view is found but not the 2_imag one.
I have tried renaming it, but it does nothing. Also, I have notice that i can't find the RelativeLayout and CardView containig both either.
UPDATE: It seems that I can't find even the main CoordinatorLayout

Solved, a fragment-v21.xml file was being loaded instead of fragment.xml.
The v21 one had different code.

view scrolls down to tabhost when fragment opened

When I open fragment with scrollview and tabhost inside the scrollview, it automatically scrolls down to the start of the tabhost hiding the top part of the scrollview. I've tried changing various things, nothing worked so far. Will keep trying, just throwing this here in hopes someone can help me. Here is the relevant parts of the code.

mTabHost = (FragmentTabHost) view.findViewById(android.R.id.tabhost);
mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("", ContextCompat.getDrawable(getActivity(), R.drawable.ic_c_text)),

The view atuomatically scrolls down to the start of the tabwidget. I'll keep editing as I try new things.
I tried scrollView.scrollTo(0, 0) and scrollView.fullScroll(ScrollView.FOCUS_UP) without success.

I get "No Tab known for Tag null" at android.support.v4.app.FragmentTabHost.doTabChanged.
The error is resolved if I change return rootView to return mTabHost. But then the fixed area at top isn't showing. Its only displaying 3 tabs at the top of the screen.
I tried using Activity to set this particular screen and it worked fine(both fixed area at top and tabs are displayed correctly) but I need it using fragments as I am using Navigation Drawer so this has to be fragment. Please advice.

I made a few changes to your code:
- In implementation, use the FragmentTabHost specified in layout
- Use Framelayout specified within FragmentTabHost Element in layout in TabHost setup method. It seems to work, check out code below:

You can use this library. Having a Tabs with Navigation Drawers is the not provided directly. If u want to have tabs in fragment just like google-play music. I advice you to use this library.
Just create the navigation drawer in the same way we create and jsut properly intergrate it. Thats set very simple.
The Solution provided by #Haresh may work. But if it doesn't apply the link I have provided will definetly work. I have used that library in my project refer link1 and link2
Hope it helps

Try this way,hope this will help you to solve your problem.

Can not open fragment in FrameLayout

Helo every one, i try to open fragment in FrameLayout, but the screen is white. My code is:

Apply a background to the linear layout in the statistic fragment xml

I think you have set visibility to invisible inside frame layout so please edit your layout file
from
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:visibility="invisible"
android:layout_width="0dp"
android:layout_height="0dp"
/>
</android.support.v4.app.FragmentTabHost>
remove this line and try again.
android:visibility="invisible"
