我将 Viewpager 与 TabLayout 一起使用,并在 setOnTabSelectedListener 触发的片段之间滑动,与单击选项卡相同。

更新后的 gradle 依赖项有问题,即滑动不再触发 setOnTabSelectedListener,仅在单击选项卡时。

将所有依赖项从 22 更改为 23 时,是否需要做一些不同的事情?

这是 Gradle 依赖项:

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:design:23.0.0'
    compile 'com.android.support:appcompat-v7:23.0.0'
    compile 'com.google.android.gms:play-services:7.8.0'
    compile 'com.android.support:support-v4:23.0.0'

    compile 'com.android.support:recyclerview-v7:23.0.0'
}

以下是我如何对 TabLayout 执行制表符:

private TabLayout tabLayout;

private void setupTablayout(){

    tabLayout.addTab(tabLayout.newTab().setText(getString(R.string.tab1)));
    tabLayout.addTab(tabLayout.newTab().setText(getString(R.string.tab2)));
    tabLayout.addTab(tabLayout.newTab().setText(getString(R.string.tab3)));

    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

    final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
    final PagerAdapter adapter = new PagerAdapter
            (getSupportFragmentManager(), tabLayout.getTabCount(), this);
    viewPager.setAdapter(adapter);
    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            Voids.savePreferences(getApplicationContext(), Voids.CHAT_SELECTED_TAB, tab.getPosition());
            viewPager.setCurrentItem(tab.getPosition());
            switch (tab.getPosition()) {
                case 0:
                    // Do first tab actions
                    break;
                case 1:
                    // Do second tab actions
                    break;
            }
        }

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

        }

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

        }
    });
}

看起来这是一个错误。如果我不得不猜测,滑动和点击的组合会导致视图寻呼机的状态变得不稳定。
