让tablayout中的Tab平铺:在tablayout布局中写:
app:tabMaxWidth="0dp"
app:tabGravity="fill"
app:tabMode="fixed"
这是要放TabLayout的Fragment:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:id="@+id/tl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabIndicatorColor="#FF00FF00"
app:tabSelectedTextColor="#FF00FF00"
app:tabTextColor="#FF000000"
app:tabMode="scrollable"
app:tabGravity="center"/>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
这是Fragment:
public class ZhuyeMyFragment extends Fragment{
private String[] mTitle = new String[4];
private String[] mData = new String[4];
{
for(int i=0;i<4;i++) {
mTitle[i] = "title" + i;
mData[i] = "data" + i;
}
}
TabLayout mTabLayout ;
ViewPager mViewPager ;
FragmentPagerAdapter mAdapter;
Zhuti zt;
Zuixin zx;
Zl zl;
Rm rm;
ArrayList<Fragment> flist;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.zhuye_layout,null);
mTabLayout = (TabLayout)view.findViewById(R.id.tl);
mViewPager = (ViewPager)view.findViewById(R.id.viewpager);
FragmentManager man = getActivity().getSupportFragmentManager();
initFragment();
flist=new ArrayList<Fragment>();
flist.add(zx);
flist.add(zl);
flist.add(rm);
flist.add(zt);
mTabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
mViewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
final TabLayout.TabLayoutOnPageChangeListener listener =
new TabLayout.TabLayoutOnPageChangeListener(mTabLayout);
mViewPager.addOnPageChangeListener(listener);
mAdapter= new FragmentAdapter(man,flist);
mViewPager.setAdapter(mAdapter);
mTabLayout.setTabsFromPagerAdapter(mAdapter);
return view;
}
private void initFragment() {
zt=new Zhuti();
zx=new Zuixin();
zl=new Zl();
rm=new Rm();
}
}
这是FragmentAdapter:
public class FragmentAdapter extends FragmentPagerAdapter {
private String [] title = {"最新日报","热门","专栏","主题日报"};
private List<Fragment> fragmentList;
public FragmentAdapter(FragmentManager fm, List<Fragment> fragmentList) {
super(fm);
this.fragmentList = fragmentList;
}
@Override
public Fragment getItem(int position) {
return fragmentList.get(position);
}
@Override
public int getCount() {
return fragmentList.size();
}
@Override
public CharSequence getPageTitle(int position) {
return title[position];
}
}
