我创建了一个片段扩展类调用布局如下

I create a fragment extend class to call layout as following

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

   <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"
        />

    <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"

        />

</LinearLayout>



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;
    }
}

现在使用它创建的布局像这样

now to use it I create layout like this

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

    <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" />

    <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"
    >
    </LinearLayout>



</LinearLayout>

按钮的单击事件我说

on the click event of the button I say

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();


            }
        }); 

但它引发错误的方法getFragmentManager（）是未定义的类型新View.OnClickListener（）{}

任何想法如何解决

推荐答案

如果呼叫活动从片段然后在下面code或致电片段的片段，然后只需更换而不是startactivity的onclick方法code

if call activity from fragment then code below or call fragment to fragment then simply replace the code instead of startactivity onclick method

public class FragmentA extends Fragment implements OnClickListener{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View v = inflater.inflate(R.layout.fragment_start, container, false);

        Button button1 = (Button) v.findViewById(R.id.StartButton);
        button1.setOnClickListener(this);
        return v;
    }

    @Override
    public void onClick(View v) {
        startActivity(new Intent(getActivity(),testing.class));
        }
    }
}
