问题描述

我有需要标签导航后期需求变更。我已经使用ActionBarSherlock在我的应用程序。 previously我的用户界面包括活动。但是从我读的TabBar需要片段活动?如何有没有什么办法,我可以保持我现有的code和实施的TabBar或将这一要求我的应用程序的完全重新写?我所有的活动延伸SherlockActivity?

亲切的问候,

解决方案

当然,你将不必重新编写应用程序。你只需要一些refractoring仅此而已。

首先,你应该通过移动code到 SherlockFragment 启动(S)。

因此​​,让我们说,你有3个活动: ActivityA ActivityB ActivityC

1 - 创建3 SherlockFragments:碎裂 FragmentB FragmentC

2 - 将你的code的片段,并进行必要的修改(如覆盖,上下文引用,等等。)

3 - 现在设置您使用Tab键导航FragmentActivity:

    私人碎裂mFragmentA;
    私人FragmentB mFragmenB;
    私人FragmentC mFragmentC;

I have a late requirement change that requires tab navigation. I have already using ActionBarSherlock in my application. Previously my UI consisted of Activities. However from what i read the TabBar requires Fragment Activities? How is there any way i can keep my existing code and implement the TabBar or would this require a complete re write of my application ? All of my activities extends SherlockActivity ?

Kind Regards,

解决方案

Of course you won't have to re-write your application. You just need some refractoring that's all.

First you should start by moving your code to SherlockFragment(s).

So let's say you have 3 Activities: ActivityA, ActivityB and ActivityC.

1 - Create 3 SherlockFragments: FragmentA, FragmentB and FragmentC.

2 - Move your code to the fragments and make the necessary modifications (e.g. Overrides, Context references, etc.).

3 - Now to setup your main FragmentActivity with Tab navigation:

public class MainActivity extends SherlockFragmentActivity implements
        ActionBar.TabListener, ViewPager.OnPageChangeListener {

    private FragmentA mFragmentA;
    private FragmentB mFragmenB;
    private FragmentC mFragmentC;

    private ViewPager mViewPager;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_layout);
        mViewPager = (ViewPager) findViewById(R.id.pager);
        mViewPager.setAdapter(new MainPagerAdapter(
                getSupportFragmentManager()));
        mViewPager.setOnPageChangeListener(this);
        mViewPager.setPageMarginDrawable(R.drawable.border);
        mViewPager.setPageMargin(16);
        final ActionBar actionBar = getSupportActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        actionBar.addTab(actionBar.newTab().setText(R.string.tab_a_title)
                .setTabListener(this));
        actionBar.addTab(actionBar.newTab().setText(R.string.tab_b_title)
                .setTabListener(this));
        actionBar.addTab(actionBar.newTab()
                .setText(R.string.tab_c_title).setTabListener(this));
    }

    @Override
    public void onPageSelected(int position) {
        getSupportActionBar().setSelectedNavigationItem(position);
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        mViewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onPageScrollStateChanged(int arg0) {
    }

    @Override
    public void onPageScrolled(int arg0, float arg1, int arg2) {
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }

    private class MainPagerAdapter extends FragmentPagerAdapter {
        public MainPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            switch (position) {
            case 0:
                return (mFragmentA = new FragmentA());

            case 1:
                return (mFragmentB = new FragmentB());

            case 2:
                return (mFragmentC = new FragmentC());

            }
            return null;
        }


        @Override
        public int getCount() {
            return 3;
        }
    }
}
