I have an application with a side menu created from fragments.
The problem comes when I want to create tabs in one of the fragments.
I have tried many examples and not work for me.
fragment_home.xml
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:orientation="horizontal"
></TabWidget>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
></FrameLayout>
</LinearLayout>
FragmentHome.java
public class FragmentInicio extends Fragment {
private FragmentTabHost mTabHost;
public FragmentInicio() {}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment_home, container, false);
try{
//HERE TABHOST????
}catch(Exception e){
Log.e("UDI", e.getMessage());
}
return view;
}
#Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Log.d("EVENT", "OnCreate");
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onViewCreated(view, savedInstanceState);
}
#Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
((HomeActivity) activity).onSectionAttached(1);
}
}
What can I do?

Thank you!
I know I'm late but this might help someone else.
To use FragmentTabHost inside fragment you can do this.
Create layout resource file
fragment_tab_host.xml
<?xml version="1.0" encoding="utf-8"?>
<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>
FrameLayout with id realtabcontent is which will show current tab content which is in this case FirstFragment, SecondFragment and ThirdFragment
TabHostWidgetFragment.java code will be
public class TabHostWidgetFragment extends Fragment {
private static final String TAG = TabHostWidgetFragment.class.getSimpleName();
public TabHostWidgetFragment() { }
private FragmentTabHost fragmentTabHost;
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
Log.i(TAG, "onCreateView: ");
return inflater.inflate(R.layout.fragment_frag_tab_host_widget, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Log.i(TAG, "onViewCreated: ");
fragmentTabHost = view.findViewById(android.R.id.tabhost);
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Log.i(TAG, "onActivityCreated: ");
fragmentTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
fragmentTabHost.addTab(fragmentTabHost.newTabSpec("First Tab").setIndicator("First Tab"), FirstFragment.class, null);
fragmentTabHost.addTab(fragmentTabHost.newTabSpec("Second Tab").setIndicator("Second Tab"), SecondFragment.class, null);
fragmentTabHost.addTab(fragmentTabHost.newTabSpec("Third Tab").setIndicator("Third Tab"), ThirdFragment.class, null);
}
public class FirstFragment extends Fragment {
private static final String TAG = FirstFragment.class.getSimpleName();
public FirstFragment() { }
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
Log.i(TAG, "onCreateView: ");
return inflater.inflate(R.layout.fragment_first, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Log.i(TAG, "onViewCreated: ");
}
}
public class SecondFragment extends Fragment {
private static final String TAG = SecondFragment.class.getSimpleName();
public SecondFragment() { }
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
Log.i(TAG, "onCreateView: ");
return inflater.inflate(R.layout.fragment_second, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Log.i(TAG, "onViewCreated: ");
}
}
public class ThirdFragment extends Fragment {
private static final String TAG = ThirdFragment.class.getSimpleName();
public ThirdFragment() { }
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container,
#Nullable Bundle savedInstanceState) {
Log.i(TAG, "onCreateView: ");
return inflater.inflate(R.layout.fragment_third, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
Log.i(TAG, "onViewCreated: ");
}
}
}
Layout resources for FristFragment, SecondFragment and ThirdFragment

If you want to make it swipeable then add ViewPager after FrameLayout with id realtabcontent as written below and implement viewPager logic.
<?xml version="1.0" encoding="utf-8"?>
<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="0"/>
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
And TabHostWidgetFragment.java class will be
Create separate or inner MyTabFactory.java class
public class MyTabFactory implements TabHost.TabContentFactory {
private final Context context;
public MyTabFactory(Context context) {
this.context = context;
}
#Override
public View createTabContent(String s) {
View v = new View(context);
v.setMinimumWidth(0);
v.setMinimumHeight(0);
return v;
}
}
And then add tabs to tabhost like this. This is essential to setContent with MyTabFactory. If you add tabs like I mentioned above in code snippet, there will be issue which is, It will add fragments two times, one because of TabHost and one because of ViewPager.
fragmentTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);
fragmentTabHost.addTab(fragmentTabHost.newTabSpec("First Tab").setIndicator("First Tab").setContent(new MyTabFactory(getActivity())));
fragmentTabHost.addTab(fragmentTabHost.newTabSpec("Second Tab").setIndicator("Second Tab").setContent(new MyTabFactory(getActivity())));
fragmentTabHost.addTab(fragmentTabHost.newTabSpec("Third Tab").setIndicator("Third Tab").setContent(new MyTabFactory(getActivity())));
You can either use android.support.v4.app.FragmentTabHost or TabHost It will work same for both.

Hey all I am having a little bit of an issue with trying to call a fragment that has the videoview within it into my current fragment page.
When I click on the test button I set up it goes through the code without error but never shows the video fragment - I even gave it a background color of red so I could see it load into my current view.
My goal here is just to send a parameter of the video path to the video fragment videoview player and start playing it.
videoPlay.java
public class videoPlay extends Fragment {
public videoPlay(){
//constructor
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout._fragvideoplay, container, false);
MediaController mc= new MediaController(getActivity());
VideoView view = (VideoView)rootView.findViewById(R.id.videoView);
String path = Environment.getExternalStorageDirectory().getAbsolutePath().toString() + "/sddir/Bubble Guppies.mp4";
view.setVideoURI(Uri.parse(path));
view.setMediaController(mc);
view.start();
return rootView;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
}
}

The path to the movie is correct. And the movie is there in the "external" SD card path. Clicking around on the new fragment (videoPlay) yields no video menu (play, remind, pause...) so its not there.
Any help would be great!
I am trying replace fragment first on second in ViewPager. And I have small problem becouse after replace still i see in background fragment first and they are working listner from fragment first. What am i doing wrong ? I replace first_fragment view but it doesn't work. In other project i were done somthing simular and it's working well !

I am trying to inflate new error.xml layout whenever webview catches error and executes onRecievedError() method. I am half way through but the problem is i get both the view... my error.xml view as well as *"webpage not found error "*view so please help me with this.
Fragment.java
public class menu_1 extends Fragment {
private WebView wv;
private TextView tv;
RelativeLayout layout;
#Override
public View onCreateView(final LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_1, container, false);
wv = (WebView) v.findViewById(R.id.frag1_web);
wv.loadUrl("file:///res/raw/web1.html");
WebSettings ws = wv.getSettings();
ws.setJavaScriptEnabled(true);
wv.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
super.onReceivedError(view, request, error);
Toast.makeText(getActivity().getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
LayoutInflater inflater1=getActivity().getLayoutInflater();
View v=inflater1.inflate(R.layout.show_error,null);
view.addView(v);
}
});
return v;
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//you can set the title for your toolbar here for different fragments different titles
getActivity().setTitle("Menu 1");
}
}
show_error.xml
<?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="match_parent">
<TextView
android:id="#+id/errorText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="Problem Loading Page"
android:textColor="#android:color/black"
android:textSize="24sp" />
</RelativeLayout>

android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
Update fragment layout
Fragment_main.xml
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
Hide webview on Error & show text view
wv.setWebViewClient(new WebViewClient() {
#Override
public void onReceivedError(WebView view, WebResourceRequest request, WebResourceError error) {
super.onReceivedError(view, request, error);
Toast.makeText(getActivity().getApplicationContext(), "Error", Toast.LENGTH_LONG).show();
webView.setVisibility(View.GONE);
textView.setVisibility(View.VISIBLE);
}
});
hi there I have 2 XML layout and 2 java class. I want merg them.
in main.activity.java I call them by this method:
switch (position % 4) {
case 0:
return WebViewGoogle.newInstance();
case 1:
return ScrollFragment.newInstance();
}
ScrollFragment.java:
public class ScrollFragment extends Fragment {
private ObservableScrollView mScrollView;
public static ScrollFragment newInstance() {
return new ScrollFragment();
}
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_scroll, container, false);
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mScrollView = (ObservableScrollView) view.findViewById(R.id.scrollView);
MaterialViewPagerHelper.registerScrollView(getActivity(), mScrollView, null);
}
}
Also this is WebViewGoogle.java
public class WebViewGoogle extends Fragment {
private ObservableWebView mWebView;
public static WebViewGoogle newInstance() {
return new WebViewGoogle();
}
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.webview_layout, container, false);
}
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mWebView = (ObservableWebView) view.findViewById(R.id.webViewPars);
MaterialViewPagerHelper.preLoadInjectHeader(mWebView);
mWebView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
MaterialViewPagerHelper.injectHeader(mWebView, true);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
mWebView.loadUrl("http://www.google.com");
MaterialViewPagerHelper.registerWebView(getActivity(), mWebView, null);
}
}
Now I have 2 xml file with this content:
fragment_scroll.xml:
<com.github.ksoichiro.android.observablescrollview.ObservableScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include layout="#layout/material_view_pager_placeholder"/>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="#dimen/cardMarginVertical"
android:layout_marginLeft="#dimen/cardMarginHorizontal"
android:layout_marginRight="#dimen/cardMarginHorizontal"
android:layout_marginTop="#dimen/cardMarginVertical"
android:background="#android:color/white"
app:cardElevation="4dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="1000dp"
android:orientation="vertical">
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
</com.github.ksoichiro.android.observablescrollview.ObservableScrollView>
and another xml is webview_layout.xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="5dp"
>
<com.github.ksoichiro.android.observablescrollview.ObservableWebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webViewPars"
android:background="#android:color/transparent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
These 2 layout and their java class work correctly now.
But I want to merge them. why? because I want put webview in a CardView
So I merhe 2 xml layouts in these way: (newlayout.xml)
<com.github.ksoichiro.android.observablescrollview.ObservableScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/material_view_pager_placeholder"/>
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="#dimen/cardMarginVertical"
android:layout_marginLeft="#dimen/cardMarginHorizontal"
android:layout_marginRight="#dimen/cardMarginHorizontal"
android:layout_marginTop="#dimen/cardMarginVertical"
android:background="#android:color/white"
app:cardElevation="4dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="1000dp"
android:orientation="vertical">
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="5dp"
android:paddingRight="5dp"
>
<com.github.ksoichiro.android.observablescrollview.ObservableWebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webViewPars"
android:background="#android:color/transparent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
</com.github.ksoichiro.android.observablescrollview.ObservableScrollView>
I think it is true but how can I do it for their java class?
step 1:
I create a new java claaa:
newclass.java
step 2
in main_activity I call it:
case 3: return newclass.newInstance();
Now I have 2 ID in newlayout: scrollView and webViewPars...now how can I merge 2 java class ...?
I have question, because I do not know what is wrong. Does not display the activity of activity_main_fragment.xml me and I do not know why. Do you have any suggestions what to change?
I created two fragments fragment_a and fragment_b and I want to display them connected to the fragment_a when you click on an item in a listview information came to me in fragment_b.

FragmentA.java
public class FragmentA extends Fragment implements AdapterView.OnItemClickListener{
ListView list;
Communicator communicator;
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
communicator = (Communicator) getActivity();
list = (ListView) getActivity().findViewById(R.id.listView22);
ArrayAdapter adapter = ArrayAdapter.createFromResource(getActivity(), R.array.titles, android.R.layout.simple_list_item_1);
list.setAdapter(adapter);
list.setOnItemClickListener(this);
return inflater.inflate(
R.layout.fragment_a, container, false);
}
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l){
communicator.respond(i);
}
}
FragmentB.java
public class FragmentB extends Fragment{
TextView text;
#Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
text = (TextView) getActivity().findViewById(R.id.textView);
return inflater.inflate(
R.layout.fragment_b, container, false);
}
public void changeData(int i)
{
Resources res = getResources();
String[] descriptions = res.getStringArray(R.array.descriptions);
text.setText(descriptions[i]);
}
}
EcologicalInformationActivity.java
public class EcologicalInformationActivity extends FragmentActivity implements Communicator{
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_fragment);
}
#Override
public void respond(int i){
FragmentManager manager = getFragmentManager();
FragmentB f2 = (FragmentB) manager.findFragmentById(R.id.fragment2);
f2.changeData(i);
}
}
EcologicalInformationActivity extends FragmentActivity so you should call getSupportFragmentManager() in place of getFragmentManager(). See documentation here. If your fragments are not already instances of the support library version, you'll need to change that too.
