Селектор значков не работает с PagerSlidingTabStrips

Я включил PagerSlidingTabStrips только с Icons. Но я selector на значках не работает с PagerSlidingTabStrips.

XML

<PagerSlidingTabStrip
    android:id="@+id/pager_sliding_tab_strip"
    android:layout_width="fill_parent"
    android:layout_height="45dip"
    android:background="@color/white"
    app:pstsDividerColor="#FFFFA500"
    app:pstsIndicatorColor="#FFFFA500"
    app:pstsTabPaddingLeftRight="14dip"
    app:pstsUnderlineColor="#FFFFA500" />

Добавлен implements IconTabProvider в мой ViewPager, который отлично работает.

public class ViewPagerAdapter extends FragmentPagerAdapter implements IconTabProvider {
    final int PAGE_COUNT = 3;
    private final int[] ICONS = { R.drawable.tab_icon_zname_contacts_selector, R.drawable.tab_icon_zname_friends_selector, 
        R.drawable.tab_icon_zname_call_log_selector };

    @Override
    public int getPageIconResId(int position) {
        return ICONS[position];
    }
}

iconSelector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/tab_icon_zname_call_log_selected" android:state_selected="true"/>
    <item android:drawable="@drawable/tab_icon_zname_call_log" android:state_selected="false"/>

</selector>

Как сделать селектор значков с PagerSlidingTabStrips? Я хочу значок с оранжевым цветом, когда эта вкладка выбрана, но она возвращает серый только независимо от того, что.

Result I'm getting

ОТВЕТЫ

Ответ 1

Я нашел исправление для Icon_Selector для PagerSlidingTabStrips внутри закрытых проблем.

Измените PagerSlidingTabStrips.java и добавьте следующий код

  private int currentPageSelected = 0; //Fix : ICON SELECTOR

Добавить в NotifyDataSetChanged метод внутри OnGlobalLayoutListener

  currentPosition = pager.getCurrentItem();
  tabsContainer.getChildAt(currentPosition).setSelected(true); //ADDED THESE
  scrollToChild(currentPosition, 0);

Изменено значение onPageSelected():

@Override
public void onPageSelected(int position) {
tabsContainer.getChildAt(currentPageSelected).setSelected(false);
currentPageSelected = position;
tabsContainer.getChildAt(position).setSelected(true);

if (delegatePageListener != null) {
     delegatePageListener.onPageSelected(position
 }
}

Мой трудный способ сделать это...

// Give the PagerSlidingTabStrip the ViewPager
tabsStrip = (PagerSlidingTabStrip) findViewById(R.id.tabs);
// Attach the view pager to the tab strip
tabsStrip.setViewPager(mViewPager);

Field field = null;
try {
    field = PagerSlidingTabStrip.class.getDeclaredField("tabsContainer");
    field.setAccessible(true);
    LinearLayout tabsContainer = (LinearLayout) field.get(tabsStrip);
    tabsContainer.getChildAt(0).setSelected(true);

} catch (NoSuchFieldException e) {
    e.printStackTrace();
} catch (IllegalAccessException e) {
    e.printStackTrace();
}

tabsStrip.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

    private int currentPageSelected = 0;

    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

    }

    @Override
    public void onPageSelected(int position) {
        Log.v("onPageSelected", tabsStrip.getClass().toString());

        Field field = null;
        try {
            field = PagerSlidingTabStrip.class.getDeclaredField("tabsContainer");
            field.setAccessible(true);
            LinearLayout tabsContainer = (LinearLayout) field.get(tabsStrip);
            tabsContainer.getChildAt(currentPageSelected).setSelected(false);
            currentPageSelected = position;
            tabsContainer.getChildAt(position).setSelected(true);

        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }


    }

    @Override
    public void onPageScrollStateChanged(int state) {

    }
});

Просто добавьте приложение: pstsTabSwitch = "true" в PagerSlidingTabStrip:

                    <com.astuetz.PagerSlidingTabStrip
                    android:id="@+id/tabs"
                    app:pstsShouldExpand="true"
                    android:layout_width="150dp"
                    android:layout_height="match_parent"
                    android:textSize="28sp"
                    app:pstsIndicatorColor="#2F041F"
                    app:pstsIndicatorHeight="2dp"
                    app:pstsTabPaddingLeftRight="14dp"
                    app:pstsTabSwitch="true"/>

Мой адаптер:

SampleFragmentPagerAdapter extends FragmentPagerAdapter implements PagerSlidingTabStrip.IconTabProvider {

private int TAB_ICONS[] = {R.drawable.io_logo, R.drawable.ic_chat_tab_unactive};
private final int[] SWITCH_ICONS = { R.drawable.tab_one, R.drawable.tab_two};

public SampleFragmentPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public int getCount() {
    return TAB_ICONS.length;
}

@Override
public Fragment getItem(int position) {
    if(position == 0){
        return new SwipeFragment();
    } else {
        return new ConversationsFragment();
    }
}


@Override
public int getPageIconResId(int position) {
    return SWITCH_ICONS[position];
}

}
