title: call fragment issue in button onclick
body: <p>I create a fragment extend class to call layout as following </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" &gt;
  
     &lt;TextView
          android:id="@+id/date_time_label"
          android:layout_centerVertical="true"
          android:layout_marginLeft="200dp"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content" 
          android:textSize="32dp"
          android:textStyle="bold"
  
          android:text="time_label"
          /&gt;
  
      &lt;TextView
          android:id="@+id/last_view_time"
          android:layout_toRightOf="@+id/date_time_label"
          android:layout_alignBaseline="@+id/date_time_label"
          android:layout_marginLeft="8dip"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:textSize="32dp"
  
          /&gt;
  
  &lt;/LinearLayout&gt;
  
  
  
  package com.appnetics;
  
  import java.text.SimpleDateFormat;
  import java.util.Date;
  
  
  
  import android.os.Bundle;
  import android.support.v4.app.Fragment;
  import android.view.LayoutInflater;
  import android.view.View;
  import android.view.ViewGroup;
  import android.widget.TextView;
  
  
  
  
  /**
   * DateTime
   */
  public class details extends Fragment {
      private static String getDateTimeString(Date time) {
          return new SimpleDateFormat("d MMM yyyy HH:mm:ss")
              .format(time);
      }
  
      private final String time = getDateTimeString(new Date());
  
      /** @see android.app.Fragment#onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle) */
      @Override
      public View onCreateView(
          LayoutInflater inflater,
          ViewGroup container,
          Bundle b)
      {
          View view = inflater.inflate(
              R.layout.details,
              container,
              false);  //!!! this is important
  
          ((TextView) view.findViewById(R.id.last_view_time))
              .setText(time);
  
          return view;
      }
  }
  </code></pre>
  
  <p>now to use it I create layout like this </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:orientation="horizontal" &gt;
  
      &lt;Button
          android:id="@+id/btn_showdetails"
          android:layout_width="100dip"
          android:layout_height="wrap_content"
          android:layout_marginLeft="110dip"
          android:layout_marginTop="15dip"
          android:text="Show Details" /&gt;
  
      &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
      android:orientation="horizontal" 
       android:id="@+id/my_parent_layout"
      &gt;
      &lt;/LinearLayout&gt;
  
  
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>on the click event of the button I say </p>
  
  <pre><code>setOnClickListener(new View.OnClickListener() {
  
              public void onClick(View v) {
  
                  FragmentManager fragmentManager = getFragmentManager();
                          FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                          details fragment = new details();
                          fragmentTransaction.add(R.id.my_parent_layout, fragment);
                          fragmentTransaction.commit();
  
  
              }
          }); 
  </code></pre>
  
  <p>but it raise error 
  <strong>The method getFragmentManager() is undefined for the type new View.OnClickListener(){}</strong></p>
  
  <p>any idea how to solve that </p>
