我想将选择器(粉红色的线)滚动到下一个选项卡(填充时)。我的片段正在滚动,但是选择器无法滚动。有人可以帮忙吗?
MainActivity.java
//Adding the tabs using addTab() method
tabLayout.addTab(tabLayout.newTab().setText("On Reserved"));
tabLayout.addTab(tabLayout.newTab().setText("On Fill-up"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
activity_main.java
<!-- our tablayout to display tabs -->
<android.support.design.widget.TabLayout
android:id="@+id/tabLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<!-- View pager to swipe views -->
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="fill_parent"></android.support.v4.view.ViewPager>

PagerAdapter pagerAdapter = new PagerAdapter(getChildFragmentManager());
viewPager.setAdapter(pagerAdapter);
tabLayout.setupWithViewPager(mBinder.viewPager);//This line is important to make tab scrollable with viewpager and it should be after set adapter to viewpager

尝试此解决方案
TabTextColor设置选项卡标题的颜色,在此处传递ColorStateList可使选项卡在不同情况下(例如选中,活动,非活动等)更改颜色。TabIndicatorColor设置选项卡下方的独立颜色。
tabLayout.setTabTextColors(ContextCompat.getColorStateList(this, R.drawable.tab_selector));
tabLayout.setSelectedTabIndicatorColor(ContextCompat.getColor(this, R.color.indicator));
希望这对您有用。

您必须像下面的代码一样在tablayout
中分配viewpager
// listener for tablayout when you select tab for change view
tabLayout.setOnTabSelectedListener(this);
// assign tablayout in viewpager
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
这是当您点击选项卡然后更改viewpager
时的替代方法
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}

当您也没有将viewpager设置为tablayout时,就会发生此问题,反之亦然。因此,请在代码中添加以下行...
PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager(),nooftabs); viewpager.setAdapter(pagerAdapter);
tabLayout.setupWithViewPager(viewpager,true);
希望这可能对您有帮助
