Getting NullPointerException when adding toolbar

Getting NullPointerExceptionwhen trying to add a toolbar which is been defined in a layout file other than main design xml file. I keep getting the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.support.v7.widget.Toolbar.findViewById(int)' on a null object reference
Here is my code
public class History_List_Details_Fragment extends Fragment {

How can I fix this error?

Add Toolbar in "history_list_details_fragment" with id "app_bar"

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.

LinearLayout is null inside button's onClick

I'm trying to hide a linearlayout on a button click and display another linearlayout which is in the same layout file. But the linearlayouts are null inside the onclick of the button.
The displayLayout and editLayout are null.
displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
displayLayout.setVisibility(View.GONE); //error occurs here
editLayout.setVisibility(View.VISIBLE);
}
});

Just fix your view ID in your code
displayLayout = (LinearLayout) findViewById(R.id.displayLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
displayLayout.setVisibility(View.GONE);
editLayout.setVisibility(View.VISIBLE);
}
});
}

error code displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
right code displayLayout = (LinearLayout) findViewById(R.id.displayLayout);
you set a not exist id.

Android setText ar the Master Page of the Tab

I have got the following code to set the values of the EditText at the header bar (master flow) but it failes and no values are assigned.
Would you please tell me how setText ?
The below is my code
(My Master Activity)
#SuppressWarnings("deprecation")
public class MainActivity extends Activity
{
private AsyncTask <Void , Void, Void> mRegisterTask ;
private String userid;
private String orderid;
...
View inflatedView = getLayoutInflater().inflate(R.layout.activity_main, null);
final EditText s = (EditText) inflatedView.findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);

you can also simple use this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText s = (EditText) findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);
}

Do this way
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText s = (EditText) findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);
// or
View inflatedView = getLayoutInflater().inflate(R.layout.activity_main, null);
final EditText s = (EditText) inflatedView.findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);
setContentView(inflatedView);
}
