android - 删除TabLayout左右填充

我正在使用标签布局，这是我的代码

  <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabGravity="center"
        app:tabMode="fixed"

        android:minHeight="?attr/actionBarSize"
        app:tabTextColor="#000"
        app:tabSelectedTextColor="#fff"
        app:tabIndicatorColor="@android:color/white"

        android:clipToPadding="false"
        />

像这样添加标签

//创建标签

TextView选项卡=（TextView）LayoutInflater.from（this）.inflate（R.layout.custom_tab，null）;
    tab.setText（“ Home”）;
    tab.setCompoundDrawablesWithIntrinsicBounds（0，R.mipmap.ic_home_black_24dp，0，0）;
    tabLayout.addTab（tabLayout.newTab（）。setCustomView（tab））;

TextView tab2 = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tab2.setText("Report");
tab2.setCompoundDrawablesWithIntrinsicBounds(0, R.mipmap.ic_trending_up_black_24dp, 0, 0);
tabLayout.addTab(tabLayout.newTab().setCustomView(tab2));

TextView tab3 = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tab3.setText("Medicine");
tab3.setCompoundDrawablesWithIntrinsicBounds(0, R.mipmap.ic_home_black_24dp, 0, 0);
tabLayout.addTab(tabLayout.newTab().setCustomView(tab3));

TextView tab4 = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
tab4.setText("More");
tab4.setCompoundDrawablesWithIntrinsicBounds(0, R.mipmap.ic_trending_up_black_24dp, 0, 0);
tabLayout.addTab(tabLayout.newTab().setCustomView(tab4));

两件事情
1.如何删除标签布局左右两侧占用的空间？

2.如何更改活动和非活动标签的文本和图标的颜色

最佳答案

从选项卡布局中的选项卡中删除填充

在您的TabLayout中，您必须将tabPaddingEnd和tabPaddingStart设置为0dp。

<android.support.design.widget.TabLayout
app:tabPaddingStart="0dp"
app:tabPaddingEnd="0dp"/>

通过更改TabLayout的选定选项卡的图标的颜色

viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);

tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setOnTabSelectedListener(
        new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {

            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                super.onTabSelected(tab);
                int tabIconColor = ContextCompat.getColor(context, R.color.tabSelectedIconColor);
                tab.getIcon().setColorFilter(tabIconColor, PorterDuff.Mode.SRC_IN);
            }

            @Override
            public void onTabUnselected(TabLayout.Tab tab) {
                super.onTabUnselected(tab);
                int tabIconColor = ContextCompat.getColor(context, R.color.tabUnselectedIconColor);
                tab.getIcon().setColorFilter(tabIconColor, PorterDuff.Mode.SRC_IN);
            }

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