一个新的Activity跳转到带有Framgment的Activity页面
思路是：新的Activity跳转到带有Fragment的Activity中，同时带有标志性的标志位。
实例代码：

另一个带有Fragment的Activity实例代码：
1 package com.cn.gordon.exhibition.walk.activity; 2 3 import java.io.File; 4 5 import android.annotation.SuppressLint; 6 import android.annotation.TargetApi; 7 import android.app.Activity; 8 import android.bluetooth.BluetoothAdapter; 9 import android.bluetooth.BluetoothManager;10 import android.content.Context;11 import android.content.Intent;12 import android.content.pm.PackageManager;13 import android.os.Bundle;14 import android.support.v4.app.Fragment;15 import android.support.v4.app.FragmentActivity;16 import android.support.v4.app.FragmentTransaction;17 import android.view.KeyEvent;18 import android.widget.Toast;19 20 import com.cn.gordon.exhibition.walk.application.GlobalVaries;21 import com.cn.gordon.exhibition.walk.db.service.InfoAndArrangeService;22 import com.cn.gordon.exhibition.walk.db.service.PositionBLEService;23 import com.cn.gordon.exhibition.walk.fragment.InformationFragment;24 import com.cn.gordon.exhibition.walk.fragment.SelectHallFragment;25 import com.cn.gordon.exhibition.walk.fragment.VisitPlanFragment;26 import com.cn.gordon.exhibition.walk.utils.DrawerLayoutUtils;27 import com.cn.gordon.exhibition.walk.utils.Utils;28 29 public class WalkMainActivity extends FragmentActivity 30 { 31 private static final int REQUEST_ENABLE_BT = 1234;32 private GlobalVaries global ;33 private DrawerLayoutUtils drawerUtil;34 private Intent bleServiceIntent,infoAndArrangeIntent;35 36 // private static String ALBUM_PATH = Utils.getSDPath() + java.io.File.separator + "exhibition_walk"; 37 38 // private AsyncImageLoader asyncImageLoader;39 40 // private ExhibitionsHallDataBase eh;41 42 @Override 43 protected void onCreate(Bundle savedInstanceState) 44 { 45 super.onCreate(savedInstanceState); 46 setContentView(R.layout.activity_main); 47 48 File dirFile = new File(Utils.ALBUM_PATH); 49 if(!dirFile.exists()){ 50 dirFile.mkdirs(); 51 } 52 53 drawerUtil = new DrawerLayoutUtils(this);54 global =(GlobalVaries) getApplication();55 global.setDrawerUtil(drawerUtil);56 57 Bundle bundle=this.getIntent().getExtras();58 if(bundle !=null && bundle.getInt("Flag") ==0 ){59 //跳转到参展计划60 FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 61 Fragment fragment = new VisitPlanFragment();62 ft.replace(R.id.fragment_layout, fragment); 63 ft.commit();64 }else if (bundle !=null && bundle.getInt("Flag") ==1 ) {65 FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 66 Fragment fragment = new InformationFragment();67 ft.replace(R.id.fragment_layout, fragment); 68 ft.commit();69 }else{70 //默认跳转到主页面71 FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 72 Fragment fragment = new SelectHallFragment(); 73 ft.replace(R.id.fragment_layout, fragment); 74 ft.commit(); 75 }76 77 init();78 } 79 80 81 82 }83
然后就是在Activity归属中的Fragment 了，代码是：
