Android的福尔摩斯FragmentTab清晰的数据

问题描述

public class PropertyAddActivity extends SherlockFragmentActivity implements OnPageChangeListener, TabListener {
private String TAG="AddActivity: ";
private FileCache fileCache;
private ViewPager mPager;
private ActionBar ab;
private static final int COUNT = 3;
static ArrayList<Integer> mSelectedPropertyType = new ArrayList<Integer>();

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

    mPager = (ViewPager) findViewById(R.id.pager);
    mPager.setAdapter(new MyAdapter(getSupportFragmentManager()));
    mPager.setOnPageChangeListener(this);
    ab = getSupportActionBar();

    ab.setDisplayShowTitleEnabled(false);
    ab.setDisplayShowHomeEnabled(false);
    ab.setNavigationMode(NAVIGATION_MODE_TABS);

    GlobalProperty.getInstance().product=new PropertyAdd();

    ab.addTab(ab.newTab().setText("Property").setTabListener(this));
    ab.addTab(ab.newTab().setText("Property Detail 1").setTabListener(this));
    ab.addTab(ab.newTab().setText("Property Detail 2").setTabListener(this));

}       

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    //listAttachImage.clear();
    mSelectedPropertyType.clear();
    super.onDestroy();
}

@Override
public void onPageScrolled(int position, float positionOffset,int positionOffsetPixels) {
    //AppLog.logString(TAG+"onPageScrolled");
}

@Override
public void onPageSelected(int position) {
    //AppLog.logString(TAG+"onPageSelected position"+position);
    getSupportActionBar().setSelectedNavigationItem(position);
}

@Override
public void onPageScrollStateChanged(int state) {
    //AppLog.logString(TAG+"onPageScrollStateChanged ");
}

@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
    //AppLog.logString(TAG+"onTabSelected position: "+tab.getPosition());
    mPager.setCurrentItem(tab.getPosition());
    //ft.replace(R.id.fragment_container, fragment);
}

@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
    //AppLog.logString(TAG+"onTabUnselected");
}

@Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
    //AppLog.logString(TAG+"onTabReselected");
}

public class MyAdapter extends FragmentStatePagerAdapter {
    public MyAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public int getCount() {
        //AppLog.logString(TAG+"COUNT: "+COUNT);
        return COUNT;
    }

    @Override
    public Fragment getItem(int position) {
        Fragment f = new Fragment();
        AppLog.logString(TAG+"position: "+position);
        switch (position) {
        case 0:
            AppLog.logString(TAG+"FRAGGGG1111111");
            f = Property1AddFragmentActivity.newInstance(position);
            break;
        case 1:
            AppLog.logString(TAG+"FRAGGGG2222222");
            f = Property2AddFragmentActivity.newInstance(position);
            break;
        case 2:
            AppLog.logString(TAG+"FRAGGGGG333333");
            f = Property3AddFragmentActivity.newInstance(position);
            break;


        default:
            AppLog.logString(TAG+"Default");
            break;
        }
        return f;
    }
}}

我有加加3选项卡现在的问题是，当我设置TAB1鉴于一些数据，并移动到TAB2的重新选择TAB1的数据TAB1是因为它是，但是当我移动到TAB3到TAB1然后tab1的数据是明确的。所以藤anyof你必须想法解决这个？

i had add add 3 tab Now the problem is that when i set some data in tab1 view and move to tab2 the reselect tab1 the data on tab1 is as it is but when i move to tab3 to tab1 then tab1 data is clear. so cany anyof you have idea to solve this?

推荐答案

目前的code似乎是部分操作栏选项卡和部分普通片段。

At the moment your code appears to be partly action bar tabs and partly ordinary fragments.

如果你试图使用的动作条的标签，那么你需要一个选项卡监听器。在onTabSelected你应该添加/替换和onTabUnselected你应该删除。

If you are trying to use action bar tabs then you need a tab listener. In onTabSelected you should add/replace and in onTabUnselected you should remove.

请参阅 http://developer.android.com/guide/topics/ UI / actionbar.html 部分添加导航选项卡的一个很好的例子。

Please see http://developer.android.com/guide/topics/ui/actionbar.htmlsection "adding navigation tabs" for a good example.
