android - 未调用滑动时的 tabLayout.setOnTabSelectedListener

Question

我试图在选择或滑动 viewPager 时突出显示选项卡图标。为此，我使用了 'tabLayout.setOnTabSelectedListener()'。但是当我滑动标签时它不会突出显示，但是当我按下标签时选择所有工作完美并且标签被突出显示。可能与gradle版本有关。我正在使用 'classpath 'com.android.tools.build:gradle:2.1.0'' 。这是 Activity :

 private int[] tabIcons = {
        R.drawable.tab_icon_home,
        R.drawable.tab_icon_cart2,
        R.drawable.tab_icon_aksia,
        R.drawable.tab_icon_menu
};
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_icon_tabs);

    toolbar = (Toolbar) findViewById(R.id.toolbar);
    toolbar.setTitleTextColor(Color.WHITE);
    setSupportActionBar(toolbar);

    frameLayout = (FrameLayout) findViewById(R.id.frameLayout);

    adapter = new ViewPagerAdapter(getSupportFragmentManager());
    viewPager = (ViewPager) findViewById(R.id.viewpager);
    viewPager.setAdapter(adapter);
    viewPager.addOnPageChangeListener(pageChangeListener);
    viewPager.setOffscreenPageLimit(10);
    tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager);
    setupTabIcons();

}


private OnPageChangeListener pageChangeListener = new OnPageChangeListener() {

    int currentPosition = 0;

    @Override
    public void onPageSelected(int newPosition) {

            FragmentLifecycle fragmentToHide = (FragmentLifecycle) adapter.getItem(currentPosition);
            fragmentToHide.onPauseFragment();

            FragmentLifecycle fragmentToShow = (FragmentLifecycle) adapter.getItem(newPosition);
            fragmentToShow.onResumeFragment();

            currentPosition = newPosition;
            adapter.notifyDataSetChanged();

    }

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

    }

    public void onPageScrollStateChanged(int arg0) { }
};

private void setupTabIcons() {


    tabLayout.getTabAt(0).setIcon(tabIcons[0]);
    tabLayout.getTabAt(1).setIcon(tabIcons[1]);
    tabLayout.getTabAt(2).setIcon(tabIcons[2]);
    tabLayout.getTabAt(3).setIcon(tabIcons[3]);

    tabLayout.getTabAt(0).getIcon().setColorFilter(Color.WHITE, PorterDuff.Mode.MULTIPLY);
    tabLayout.getTabAt(1).getIcon().setColorFilter(Color.parseColor("#81C784"), PorterDuff.Mode.SRC_IN);
    tabLayout.getTabAt(2).getIcon().setColorFilter(Color.parseColor("#81C784"), PorterDuff.Mode.SRC_IN);
    tabLayout.getTabAt(3).getIcon().setColorFilter(Color.parseColor("#81C784"), PorterDuff.Mode.SRC_IN);



    tabLayout.setOnTabSelectedListener( new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            super.onTabSelected(tab);

                tab.getIcon().setColorFilter(Color.WHITE, PorterDuff.Mode.MULTIPLY);


        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            super.onTabUnselected(tab);

            tab.getIcon().setColorFilter(Color.parseColor("#81C784"), PorterDuff.Mode.MULTIPLY);
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {
            super.onTabReselected(tab);

        }
    });


}

我找到了解决方案，在我使用的gradle中

dependencies {
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.android.support:design:23.0.0' }

我在 appcompat-v7 和设计中都从 23.0.0 更改为 23.0.1。现在一切都为我工作。
