用于Fragment的切换与跳转

 @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_zhu);        //默认进入的fragment         if (Home ==null){            Home =new HomeFragment();        }        Chagefragment(Home);    }    //切换Fragment    public void Chagefragment(Fragment fr){        //得到fragment管理类        FragmentManager manager=getSupportFragmentManager();        //得到事物        FragmentTransaction replace = manager.beginTransaction();        //隐藏之前添加的Fragment        if (fragment2 != null) {            replace.hide(fragment2);        }        //判断此fragment是否添加过        if (!fr.isAdded()) {            //如果没有就添加            replace.add(R.id.mylin, fr);        } else {            //添加了就直接显示            replace.show(fr);        }        //提交        replace.commit();        //记录当前Fragent        fragment2 = fr;    }

//点击图片监听切换

 @Override    public void onClick(View view) {        switch (view.getId()){            case R.id.home_my:                if (My ==null){                    My = new MyFragment();                }                Chagefragment(My);                break;            case R.id.home_search:                if (seach ==null){                    seach =new SeachFragment();                }                Chagefragment(seach);                break;            case R.id.home_home:                if (Home ==null){                    Home =new HomeFragment();                }                Chagefragment(Home);                break;            case R.id.home_map:                if (Map ==null){                    Map =new MapFragment();                }                Chagefragment(Map);                break;            case R.id.home_more:                if (More ==null){                    More =new MoreFragment();                }                Chagefragment(new MoreFragment());                break;        }    }

BaseActivity的跳转方法和返回按钮公共方法

//跳转页面    public void startActivity(Class<?> openClass, Bundle bundle) {        Intent intent = new Intent(this, openClass);        if (null != bundle)            intent.putExtras(bundle);        startActivity(intent);        this.overridePendingTransition(R.anim.leftin,R.anim.leftout);    }    //标题    public void Head(){        back =(ImageView)findViewById(R.id.back);        back.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                finish();            }        });
