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); } } ); 试试这个， <android.support.design.widget.TabLayout android:id="@+id/tab_layout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:background="@drawable/bg_forum_tab" app:tabIndicatorColor="@color/colorBtnBg" app:tabIndicatorHeight="0dp" app:tabPaddingBottom="-1dp" app:tabPaddingEnd="-1dp" app:tabPaddingStart="-1dp" app:tabPaddingTop="-1dp" style="@style/CustomTabLayoutStyle" app:tabTextColor="@color/colorWhite" /> 像这样设置 tabPaddingStart/tabPaddingEnd/tabPaddingTop/tabPaddingBottom Styles: <style name="CustomTabLayoutStyle" parent="Base.Widget.Design.TabLayout"> <item name="tabSelectedTextColor">@color/tab_text_selected</item> <item name="tabIndicatorColor">@color/tab_indicator</item> <item name="tabTextAppearance">@style/CustomTabTexStyle</item> </style> <style name="CustomTabTexStyle" parent="TextAppearance.Design.Tab"> <item name="android:textSize">14sp</item> <item name="android:textColor">@color/tab_text</item> ... </style> 要调整填充，您可以使用 app:tabMinWidth 或 tabPaddingStart/tabPaddingEnd/tabPaddingTop/tabPaddingBottom <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" app:tabMinWidth="50dp" app:tabPaddingBottom="1dp" app:tabPaddingEnd="1dp" app:tabPaddingStart="1dp" app:tabPaddingTop="1dp" android:minHeight="?attr/actionBarSize" app:tabTextColor="#000" app:tabSelectedTextColor="#fff" app:tabIndicatorColor="@android:color/white" android:clipToPadding="false" /> 简单来说，您可以使用下面的颜色代码 <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@color/tab_background_selected" android:state_selected="true"/> <item android:drawable="@color/tab_background_unselected"/> </selector> 并将其保存在可绘制对象中为 tab_color_selector.xml 并使用 app:tabBackground="@drawable/tab_color_selector" 所以总代码是 <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" app:tabMinWidth="50dp" android:minHeight="?attr/actionBarSize" app:tabTextColor="#000" app:tabSelectedTextColor="#fff" app:tabIndicatorColor="@android:color/white" app:tabBackground="@drawable/tab_color_selector" android:clipToPadding="false" /> 在 tab_background_selected 和 tab_background_unselected 中提供颜色，如 #000000。或者直接使用 #000000 代替 @color/tab_background_unselected 您可以添加属性： app:tabIndicatorFullWidth="false" app:tabIndicatorHeight="0dp" app:tabMinWidth="0dp" app:tabPadding="0dp" app:tabPaddingBottom="0dp" app:tabPaddingEnd="0dp" app:tabPaddingStart="0dp" app:tabPaddingTop="0dp"
