How to open fragments containing webViews in another activity on button click from fragments of another activity?

I have image-buttons in one of the fragments of an activity and want to open corresponding fragments containing webViews on button clicks in another activity.
I am a beginner so please do give appropriate codes for this.

}
//onclick methods of image buttons
public void onAboutBoardClick(View view){
}
}
These are the files in which i want that if i click on about_img_btn then it should open a fragment containing a webView in another activity. The same should be repeated for all the buttons.
Please define the further code that i have to use and mention the files where i have to use it. Thanks!

try this:
in your fragment_lower_main xml:
Give an id to the Framelayout:
<?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"
tools:context="com.example.administrator.hiha.Lower_main_Fragment">
<FrameLayout
android:id="+#id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<--Rest of the code -->
/>
</LinearLayout>
Now in code open new Fragment during button click using:
about_img_btn=(ImageButton)rootView.findViewById(R.id.about_img_btn);
about_img_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AboutUS fragment = new AboutUS();
Replace_fragment(fragment); //pass the fragment u want to replace
}
});
public void ReplaceFragment(Fragment r_fragment) {
FragmentManager fragmentManager = getActivity.getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment_container, r_fragment).commit();
}

Android Studio fragments

I'm trying to create a quiz app with a sidebar that consists of flags (image buttons), and when you click on each flag, you can type in the country it belongs to in a fragment on the right hand side of the screen. However I'm getting an error inside the if statement in my Play.java file where it says:
fragment = new FragmentOne();
and
fragment = new FragmentTwo();
Play.java

fragment = new FragmentOne();
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_place, fragment);
ft.commit();

}
}
Does anyone know what I'm doing wrong?

In your Play.java class, your Fragment variable is of type android.app.Fragment. Though your FragmentOne.java (and I assume your FragmentTwo.java as well) class is of type android.support.v4.app.Fragment.
So in your Play.java class you're trying to initialize the Fragment variable with the wrong type.
Either :
Make your FragmentOne.java and FragmentTwo.java extends android.app.Fragment instead of the support version one
Make your Fragment variable in Play.java of type android.support.v4.Fragment by changing your import.

Reading your code...
// Add the fragment to the 'fragment_container' FrameLayout
You probably need to change
<fragment
android:id="#+id/fragment_container"
To
<FrameLayout
android:id="#+id/fragment_container"
Or, not use the Java code to create the Fragment and simply add the class attribute to the XML fragment block. From the documentation...
The android:name attribute in the <fragment> specifies the Fragment class to instantiate in the layout.
Otherwise, you can show the Fragment like so
Fragment wel = new WelcomeFragment(); // correct naming schema
wel.setArguments(getIntent().getExtras());
getSupportFragmentManager()
.beginTransaction()
.add(R.id.fragment_container, wel)
.commit();

Declare your fragment_container like this,
<?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_set_up"

android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.user.timetable_test.Set_Up">
<!-- Can be any child of ViewGroup: RelativeLayout/LinearLayout/... -->
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>

I tried lots of things like adding support project of recycler-view and referencing to main project etc .
But none of the thing worked .
Any help will be appreciated :).

In recent versions of the support library (22.x), the CardView and RecyclerView libraries were provided with only Android Studio (Gradle) integration, so you needed to manually create Eclipse library projects in order to use them in Eclipse.
As of v23.01 of the Support v7 library, however, there are now library projects included in the sdk.
First, make sure that you have at least v23.01 of the Support Library:
Then, navigate to the location of the Support Library in the sdk:
Copy the recyclerview folder to your project, I created a folder called "dependency" and placed all library projects in there.
Then, import your library project into Eclipse, along with your app project:
For each library project, ensure that Is Library is checked:
Then ensure that all library projects are added to your app project:
And, ensure that all library projects are included in the build path of your app project:
Now, your Eclipse project should be configured correctly.
In this simple example, I used a RecyclerView and CardViews.
Here is the Fragment code:
public class BlankFragment extends Fragment {
public BlankFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_blank, container, false);
RecyclerView rv = (RecyclerView) rootView.findViewById(R.id.rv_recycler_view);
rv.setHasFixedSize(true);
MyAdapter adapter = new MyAdapter(new String[]{"testone", "testtwo", "testthree", "testfour"});
rv.setAdapter(adapter);
LinearLayoutManager llm = new LinearLayoutManager(getActivity());
rv.setLayoutManager(llm);
return rootView;
}
}
The Adapter for the RecyclerView:
import android.support.v7.widget.CardView;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {
private String[] mDataset;
// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public static class MyViewHolder extends RecyclerView.ViewHolder {
public CardView mCardView;
public TextView mTextView;
public MyViewHolder(View v) {
super(v);
mCardView = (CardView) v.findViewById(R.id.card_view);
mTextView = (TextView) v.findViewById(R.id.tv_text);
}
}
// Provide a suitable constructor (depends on the kind of dataset)
public MyAdapter(String[] myDataset) {
mDataset = myDataset;
}
// Create new views (invoked by the layout manager)
#Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent,
int viewType) {
// create a new view
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.card_item, parent, false);
// set the view's size, margins, paddings and layout parameters
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
holder.mTextView.setText(mDataset[position]);
}
#Override
public int getItemCount() {
return mDataset.length;
}
}

Here is my parent fragment activity
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
AppActivity appActivity = new AppActivity();
fragmentTransaction.replace(android.R.id.content, appActivity);
fragmentTransaction.commit();
AppActivity
public class AppActivity extends Fragment{
Context context;
ArrayList<ViewGroup> viewsList;
UpdateAppThread UpdateThread;
View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.app_new_layout,container, false);
context = view.getContext();
...
....
return view ;
}

This is my best guess, since your layout files and rest of the code seem fine.
Depending on your minimum SDK declared in your Manifest, if you have it lower than 11 make sure you have the following imports:
In your fragment class: import android.support.v4.app.Fragment;
In your parent Activity: import android.support.v4.app.FragmentActivity;
Make your parent Activity extend FragmentActivity instead of Activity
