我有一个TabLayout(设计支持库),它与包含三个选项卡的ViewPager绑定在一起.我设计了一个自定义布局,并将其设置为TabLayout中的每个选项卡.我一直在尝试更改当前所选选项卡的背景颜色.颜色仅包含在选项卡中的文本周围,但不占用整个选项卡空间.

以下是我的活动和自定义布局文件的代码段.

活动代码

public class CustomTabLayoutActivity extends AppCompatActivity {

private TabLayout tabLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_custom_tab_layout);
    tabLayout = (TabLayout) findViewById(R.id.tabLayout);
    ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
    setupViewPager(viewPager);
    tabLayout.setupWithViewPager(viewPager);
    tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
    setupTabLayout();
    viewPager.setCurrentItem(0);
    viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            for (int i = 0; i < tabLayout.getTabCount(); i++) {
                if (i == position) {
                    tabLayout.getTabAt(i).getCustomView().setBackgroundColor(Color.parseColor("#198C19"));
                } else {
                    tabLayout.getTabAt(i).getCustomView().setBackgroundColor(Color.parseColor("#f4f4f4"));
                }
            }
        }

        @Override
        public void …
