I got the same Problem and to my amzement I found a solution! Create a blank XML layout file like this...

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
</FrameLayout>

In the fragment where your layout is dynamically created, inflate this blank layout XML file.

  @Override
  public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup     container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.blank_layout, container, false);
    return view;

Afterwords, in onViewCreated() method you can create your layout dynamically.

  @Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
  super.onViewCreated(view, savedInstanceState);

// This will create the LinearLayout
LinearLayout ll = new LinearLayout(mContext);
ll.setOrientation(LinearLayout.VERTICAL);

// Configuring the width and height of the linear layout.
LinearLayout.LayoutParams llLP = new LinearLayout.LayoutParams(
        //android:layout_width="match_parent" an in xml
        LinearLayout.LayoutParams.MATCH_PARENT,
        //android:layout_height="wrap_content"
        LinearLayout.LayoutParams.MATCH_PARENT);
ll.setLayoutParams(llLP);

TextView tv = new TextView(mContext);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
        LinearLayout.LayoutParams.MATCH_PARENT,
        LinearLayout.LayoutParams.WRAP_CONTENT);

tv.setLayoutParams(lp);
//android:text="@string/c4r"
tv.setText("Hello android !");
//android:padding="@dimen/padding_medium"
tv.setPadding(8, 8, 8, 8);
ll.addView(tv);

ViewGroup viewGroup = (ViewGroup) view;
viewGroup.addView(ll);
}

}

package com.example.test;

import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;


public class FragmentExample extends android.app.Fragment
{

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onViewCreated(view, savedInstanceState);

        //Set a linearLayout to add buttons
        LinearLayout linearLayout = new LinearLayout(getActivity());
        // Set the layout full width, full height
        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
        linearLayout.setLayoutParams(params);
        linearLayout.setOrientation(LinearLayout.HORIZONTAL); //or VERTICAL

        Button button = new Button(getActivity());
        //For buttons visibility, you must set the layout params in order to give some width and height: 
        LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        button.setLayoutParams(params);

        Button button2 = new Button(getActivity());
                button2.setLayoutParams(params);
        //... and other views

        ViewGroup viewGroup = (ViewGroup) view;

        linearLayout.addView(button);
        linearLayout.addView(button2);

        viewGroup.addView(linearLayout);
    }
}
