1. 自定义lifecycleoffragment布局文件
  2. 在main_activity布局中引用自定义的fragment布局
  3. 到logcat中查看程勋运行的结果
  4. 代码如下:

    自定义的fragment布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#00FF00"
>

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="这是展示LifeCycleOfFragment,请到logcat中查看"
android:textColor="#000000"
android:textSize="25sp"
/>

</LinearLayout>

Fragment的java类

package com.cm.lifecycleoffragment;

import android.app.Activity;
import android.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup; /**
* Created by Administrator on 2016/1/2.
*/
public class LifeCycleOfFragment extends Fragment{ @Override
public void onAttach(Activity activity) {
super.onAttach(activity); Log.d("lifecycleoffragment","onAttach()");
} @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); Log.d("lifecycleoffragment","onCreate()");
} @Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { Log.d("lifecycleoffragment","onCreateView()");
return inflater.inflate(R.layout.lifecycleof_fragment,container,false); } @Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Log.d("lifecycleoffragment", "onActivityCreated()");
} @Override
public void onStart() {
super.onStart();
Log.d("lifecycleoffragment", "onStart()");
} @Override
public void onResume() {
super.onResume();
Log.d("lifecycleoffragment", "onResume()");
} @Override
public void onPause() {
super.onPause();
Log.d("lifecycleoffragment", "onPause()");
} @Override
public void onStop() {
super.onStop();
Log.d("lifecycleoffragment", "onStop()");
} @Override
public void onDestroyView() {
super.onDestroyView(); Log.d("lifecycleoffragment", "onDestroyView()");
} @Override
public void onDestroy() {
super.onDestroy();
Log.d("lifecycleoffragment", "onDestroy()");
} @Override
public void onDetach() {
super.onDetach(); Log.d("lifecycleoffragment", "onDetach()");
} }

在main_activity的布局文件中引用fragment

<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=".MainActivity"
> <fragment
android:name="com.cm.lifecycleoffragment.LifeCycleOfFragment"
android:id="@+id/lifecycleof_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/> </RelativeLayout>

Logcat打印的程序运行过程:

Fragment的生命周期(三)-LMLPHP

按home键返回的运行过程:

Fragment的生命周期(三)-LMLPHP

再次进入程序的运行过程:

Fragment的生命周期(三)-LMLPHP

按ctrl+f11程序的运行过程:

Fragment的生命周期(三)-LMLPHP

按back键的运行过程:

Fragment的生命周期(三)-LMLPHP

以上过程充分展示fragment的生命周期。
