解决方法
TabLayout
从
Android Design Support Library到
material design guidelines for tabs.
The Design library’s
TabLayout
implements both fixed tabs,where the
view’s width is divided equally between all of the tabs,as well as
scrollable tabs,where the tabs are not a uniform size and can scroll
horizontally.
要实现TabLayout,请检查此guide和how to add the icon for swipeable tabs以使用setIcon将图标设置为选项卡.
final int[] ICONS = new int[]{ R.drawable.ic_action_document,R.drawable.ic_action_tick,R.drawable.ic_action_trash}; .... TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs); tabLayout.setupWithViewPager(mViewPager); tabLayout.getTabAt(0).setIcon(ICONS[0]); tabLayout.getTabAt(1).setIcon(ICONS[1]); tabLayout.getTabAt(2).setIcon(ICONS[2]);
要在TabLayout检查中设置底部的选项卡 – How can I set tabs at the bottom and also hide top actionbar?,将TabLayout放在relativeLayout中并将其与父底部对齐:
<android.support.design.widget.TabLayout android:id="@+id/tab_layout" app:tabMode="fixed" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/colorPrimary" android:elevation="6dp" app:tabTextColor="#d3d3d3" app:tabSelectedTextColor="#ffffff" app:tabIndicatorColor="#ff00ff" android:minHeight="?attr/actionBarSize" android:layout_alignParentBottom="true" />
虽然您可以将标签布局放在底部,但根据Pure Android指南,尽量不要使用底部标签栏.
Other platforms use the bottom tab bar to switch between the app’s views. Per platform convention,Android’s tabs for view control are shown in action bars at the top of the screen instead.
