1、靜態(tài)加載

1、fragment layout
?2、fragment類
?3、在對(duì)應(yīng)的activity layout中加載 fragment

1、fragment layout

2、fragment class

package?com.example.administrator.fragment2;

import?android.os.Bundle;
import?android.support.annotation.Nullable;
import?android.view.LayoutInflater;
import?android.view.View;
import?android.view.ViewGroup;

import?java.util.zip.Inflater;

/**
?*?Created?by?Administrator?on?2015/7/22.
?*/
public?class?Fragment?extends?android.app.Fragment?{
????@Nullable
????@Override
????public?View?onCreateView(LayoutInflater?inflater,?ViewGroup?container,?Bundle?savedInstanceState)?{
????????/**
?????????*?將?layout轉(zhuǎn)成?view對(duì)象
?????????*/
????????View?view?=?inflater.inflate(R.layout.fragment,container,false);
????????return?view;
????}
}

3.在對(duì)應(yīng)的activity layout中加載 fragment

2動(dòng)態(tài)加載

前兩步和靜態(tài)加載一樣

不同的地方在于

package?com.example.administrator.fragment2;

import?android.app.*;
import?android.support.v7.app.ActionBarActivity;
import?android.os.Bundle;
import?android.view.Menu;
import?android.view.MenuItem;


public?class?MainActivity?extends?ActionBarActivity?{

????@Override
????protected?void?onCreate(Bundle?savedInstanceState)?{
????????super.onCreate(savedInstanceState);
????????setContentView(R.layout.activity_main);


????????//動(dòng)態(tài)加載?fragment
????????Fragment?fragment?=?new?Fragment();?//這個(gè)是我們自己定義的?Fragment
????????FragmentManager?fragmentManager?=?getFragmentManager();
????????FragmentTransaction?fragmentTransaction?=?fragmentManager.beginTransaction();

????????fragmentTransaction.addToBackStack(null);?//后退按鍵?允許
????????fragmentTransaction.add(R.id.linear,fragment);
????????fragmentTransaction.commit();
????}

}
