View still null even after inflating on OnCreateView

I have been struggling with the same crash for 4 hours already and I still cannot figure out the cause of it. Can any kind soul enlighten me ? I am getting this error
java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.view.View.findViewById(int)' on a null object reference
The moment it start to load my textview lbl it just crash and give me this error
Below is my code :
public class BookDoc extends Fragment {
View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout for this fragment
if (view != null) {
ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null) {
parent.removeView(view);
}
}
try {
view = inflater.inflate(R.layout.activity_main, container, false);
} catch (InflateException e) {
}
StrictMode.ThreadPolicy policy = new StrictMode.
ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Typeface type = Typeface.createFromAsset(getActivity().getAssets(),"fonts/verdana.ttf");
TextView lbl = (TextView) view.findViewById(R.id.textViewa);
return view

Your view is not initialized and it is still null. Before your "if statement", initialize the view as below:
view = (View) inflater.inflate(R.layout.your_layout_file, container, false);
everything else is fine

Adding Views dynamically in Linear Layout in Fragment

I am trying to add TextView to the nested linearLayout in fragmentin onCreateView, I don't know if this is the correct approach or not, new to android!
Thanks in advance
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.fragment_screen_slide_page, container, false);
List<LifeBerrysXmlParser.Item> items = (ArrayList<LifeBerrysXmlParser.Item>) getArguments().getSerializable("List");
TextView mainHeading = (TextView) rootView.findViewById(R.id.mainHeading);
ImageView mainImage = (ImageView) rootView.findViewById(R.id.articleMainImage);
LinearLayout articleLayout = (LinearLayout) rootView.findViewById(R.id.articleLayout);
TextView tev = new TextView(getActivity());
tev.setText("Hello..............");
articleLayout.addView(tev);
LifeBerrysXmlParser.Item item = items.get(getArguments().getInt("position"));
String articleMainHeading = item.mainHeading;
String articlemainImage = item.mainImage;
mainHeading.setText(articleMainHeading);
if (!articlemainImage.isEmpty()) {
Picasso.with(getContext()).load(articlemainImage).into(mainImage);
}
return rootView;
}
can anyone please help me what I am doing wrong?
here is my xml for the fragment

You have mistake in your article layout. Your article layout has horizontal orientation, and it's child TextView has match_parent width, so when you add new child, it'll be outside the screen. Change orientation to vertical:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/articleLayout"
android:orientation="vertical"> <---- Change this line
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Read More"
android:textSize="15dp"
android:textStyle="bold"
android:layout_gravity="center"
android:clickable="true"
android:focusable="false"
android:gravity="center"
android:onClick="readMore"
android:padding="1dp"
android:textColor="#android:color/holo_green_light" />
</LinearLayout>

Getting NullPointerException when adding toolbar

How can I fix this error?

Add Toolbar in "history_list_details_fragment" with id "app_bar"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

The error states clearly. Inside history_list_details_fragment.xml there is no Toolbar. Try to add it.
Or more probably the Toolbar is in you Activity layout, so init it inside Activity.

How can I display the layout containing the buttons down on the screen

With the layout below the buttons are being shown on top of the page. How can I make them appear below, after the container, down on the page?
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/container"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_gravity="center_vertical|center_horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/Main"
android:onClick="ClickHomePage"
android:text= "#string/Home"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/map"
android:onClick="ClickClients"
android:text= "#string/Clients"
>
</Button>
</LinearLayout>
</LinearLayout>
The MainActivity looks as follows and the HomePage.xml is also below
public class MainActivity extends ActionBarActivity
{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GetButtonClicked(5);
setContentView(R.layout.activity_main);
}
public void GetButtonClicked(int position)
{
// update the main content by replacing fragments
Fragment fragment = null;
switch (position){
case 0:
fragment= new FirstPageFragment();
break;
default:
fragment = new FirstPageFragment();
break;
}
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
}
public void ClickHomePage(View view){
GetButtonClicked(0);
}
public void ClickClients(View view){
GetButtonClicked();
}
}
<FrameLayout 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" tools:context="com.test.FirstPageFragment" android:background="#drawable/theme">
</FrameLayout>
This is the FirstPage
public class FirstPageFragment extends Fragment {
public FirstPageFragment() {
// 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_first_page, container, false);
}
}

Use ralative layout insted of linear.

Make a different layout for bottom buttons, and then at the last of your container layout use this:
<include android:id="#+id/bottomLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
layout="#layout/bottom_buttons"/>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<Button
android:id="#+id/Main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickHomePage"
android:text="#string/Home" />
<Button
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickClients"
android:text="#string/Clients" >
</Button>
</LinearLayout>
Try this

Use RelativeLayout with android:layout_alignParentBottom="true" step by step guide is available here.
Your skeleton for layout should look like this
<RelativeLayout
<LinearLayout android:layout_alignParentBottom="true">
<Button
<Button
</LinearLayout>
</RelativeLayout>
Final Layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="#+id/Main"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickHomePage"
android:text="Home" />
<Button
android:layout_marginLeft="30dp"
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="ClickClients"
android:text="Clients" >
</Button>
</LinearLayout>

The issue was that I did not include the container in another layout...
<RelativeLayout 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"
tools:context="com.test.MainPageActivityActivity">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:id="#+id/container">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:layout_alignParentTop="#+id/container">
and insert buttons layout here....
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:id="#+id/Main"
android:onClick="ClickHomePage"
android:text= "#string/Home"
/>

It show the java.lang.NullPointerException when set the framelayout to VISIBLE in android

I detect the WIFI connect , when WIFI connect is break.
It will show the framelayout on the top of all widgets.
public class MjpegPlayerFragment extends Fragment {
public static FrameLayout reconnect_layout;
private class GetTimeStamp extends AsyncTask<URL, Integer, String> {
protected void onPostExecute(String result) {
Activity activity = getActivity() ;
if (activity != null) {
reconnect_fragment();
}
super.onPostExecute(result) ;
}
}
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.preview_player, container, false) ;
reconnect_layout = (FrameLayout) getActivity().findViewById(R.id.reconnect_layout);
return view ;
}
public static void reconnect_fragment() {
reconnect_layout.setVisibility(View.VISIBLE);
}
And the code of xml is like the following:

When it call the reconnect_fragment(); it show the java.lang.NullPointerException at reconnect_layout.setVisibility(View.VISIBLE);
Does there has any wrong ?
How to solve this problem ?

As you said in your comment framelayout is in fragment layout
So Change to
reconnect_layout = (FrameLayout) view.findViewById(R.id.reconnect_layout);
If it is in activity xml you use getActivity().findViewById

replace
reconnect_layout = (FrameLayout) getActivity().findViewById(R.id.reconnect_layout);
with
reconnect_layout = (FrameLayout) view.findViewById(R.id.reconnect_layout);
