您可以使用以下函数设置TabLayout位置

public void setTab(){
 tabLayout.setScrollPosition(YOUR_SCROLL_INDEX,0,true);
 tabLayout.setSelected(true);
}

用这个:

<android.support.design.widget.TabLayout
    android:id="@+id/patienthomescreen_tabs"
    android:layout_width="match_parent"
    android:layout_height="72sp"
    app:tabGravity="fill"
    app:tabMode="fixed"
    app:tabIndicatorColor="@android:color/white"
    app:tabSelectedTextColor="@color/green"/>

在OnClickListener中:

TabLayout tabLayout = (TabLayout) findViewById(R.id.patienthomescreen_tabs);
TabLayout.Tab tab = tabLayout.getTabAt(someIndex);
tab.select();

请记住，如果currentTabIndex和index是相同的，那么这将发送您的流到onTabReselected而不是onTabSelected。

如果你使用TabLayout没有viewPager，这有助于

 mTitles = getResources().getStringArray(R.array.tabItems);
    mIcons = getResources().obtainTypedArray(R.array.tabIcons);
    for (int i = 0; i < mTitles.length; i++) {

        tabs.addTab(tabs.newTab().setText(mTitles[i]).setIcon(mIcons.getDrawable(i)));
        if (i == 0) {
            /*For setting selected position 0 at start*/
            Objects.requireNonNull(Objects.requireNonNull(tabs.getTabAt(i)).getIcon()).setColorFilter(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary), PorterDuff.Mode.SRC_IN);
        }
    }

    tabs.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            Objects.requireNonNull(tab.getIcon()).setColorFilter(ContextCompat.getColor(getApplicationContext(), R.color.colorPrimary), PorterDuff.Mode.SRC_IN);
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {
            Objects.requireNonNull(tab.getIcon()).setColorFilter(ContextCompat.getColor(getApplicationContext(), R.color.white), PorterDuff.Mode.SRC_IN);
        }

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

        }
    });

您可以使用以下函数设置TabLayout位置

public void setTab(){
 tabLayout.setScrollPosition(YOUR_SCROLL_INDEX,0,true);
 tabLayout.setSelected(true);
}

我是这样解决的:

void selectPage(int pageIndex){
    tabLayout.setScrollPosition(pageIndex,0f,true);
    viewPager.setCurrentItem(pageIndex);
}

如果您在理解上有困难，这段代码可以帮助您

private void MyTabLayout(){
    TabLayout.Tab myTab = myTabLayout.newTab(); // create a new tab
    myTabLayout.addTab(myTab); // add my new tab to myTabLayout
    myTab.setText("new tab"); 
    myTab.select(); // select the new tab
}

你也可以在你的代码中添加这个:

myTabLayout.setTabTextColors(getColor(R.color.colorNormalTab),getColor(R.color.colorSelectedTab));
