Fragment的生命周期（三）

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：

按home键返回的运行过程：

再次进入程序的运行过程：

按ctrl+f11程序的运行过程：

按back键的运行过程：

以上过程充分展示fragment的生命周期。
