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.
FragmentProfile.java
public class FragmentProfile extends Fragment {
private FragmentTabHost mTabHost;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_profile, container, false);
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)),
FragmentProfileTab1.class, null);
return view;
}
}

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'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.

public class FeedFragment extends Fragment {
private WebView livestream;
private WebView livefeed;
public FeedFragment() {
// Required empty public constructor
}
#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"?>

I strongly recommend that you read Google's a layout .
findViewById is returning null when searching for an ImageView inside a fragment, but not for a TextView.
Here is my code:
fragment.xml:
<android.support.design.widget.CoordinatorLayout 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"
tools:context="com.herecomesthefragmentname">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/card_1"
android:clickable="true"
android:foreground="?android:attr/selectableItemBackground">
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/txt_1"
android:textAppearance="#android:style/TextAppearance.Medium" />
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/2_card"
app:cardUseCompatPadding="true"
app:cardBackgroundColor="#android:color/white">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/mr_layout">
<ImageView
android:id="#+id/2_imag"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:srcCompat="#drawable/img_1"
android:scaleType="fitStart"
android:adjustViewBounds="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/txt_2"
android:textAppearance="#style/TextAppearance.AppCompat.Large.Inverse"
/>
</RelativeLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
<!-- here goes another cardview -->
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
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.
I'm using CoordinateLayout in fragment's layout file. There I need to use ImageButton between two layouts. I got sample code from [this][1] answer.
but when i put my fragment in viewpager it dose not work correctly here is my code.
<img src="https://i.stack.imgur.com/wZasU.png"/>
public class Profile extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View Rootview =inflater.inflate(R.layout.tab_profile_fragment, container, false);
CircleImageView fab = (CircleImageView) Rootview.findViewById(R.id.fab);
return Rootview;
}
}

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);
Helo every one, i try to open fragment in FrameLayout, but the screen is white. My code is:
public class ProfileActivity extends FragmentActivity {
Database db;
TextView tvName, tvCity;
ImageView imageView;
private FragmentTabHost mTabHost;
FrameLayout frameLayout;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
frameLayout = (FrameLayout) findViewById(R.id.frame_layout);
initialize();
}
private void initialize() {
tvName = (TextView) findViewById(R.id.tv_name);
tvCity = (TextView) findViewById(R.id.tv_city);
db = Database.getInstance(this);
imageView = (ImageView) findViewById(R.id.iv_profile);
Fragment fragment = new StatisticFragment();
FragmentTransaction transaction = getSupportFragmentManager()
.beginTransaction();
transaction.replace(R.id.frame_layout, fragment);
transaction.addToBackStack(null);
transaction.commit();
}
}

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"
