1.导入依赖

implementation ‘com.google.android.material:material:1.0.0‘

2.新建Fragment1 2.1fragment.xml

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> < TextView android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center" android:text="hello" android:textSize="45dp" android:id="@+id/tvName"/> < /LinearLayout>

3.新建MainActivity 3.1 activity_main.xml

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity"> < com.google.android.material.tabs.TabLayout android:layout_width="match_parent" android:id="@+id/tl_tabs" android:layout_height="40dp"/> < androidx.viewpager.widget.ViewPager android:id="@+id/vp_content" android:layout_width="match_parent" android:layout_height="match_parent"> < /androidx.viewpager.widget.ViewPager> < /LinearLayout>

3.2 MainActivity.class

public class MainActivity extends AppCompatActivity {private TabLayout tlTabs; private ViewPager vpContent; List< Fragment> fragments = new ArrayList< > (); List< String> titles = new ArrayList< > (); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initViews(); fragments.add(new MyFragment("第一页")); fragments.add(new MyFragment("第二页")); fragments.add(new MyFragment("第三页")); fragments.add(new MyFragment("第四页")); fragments.add(new MyFragment("第五页")); titles.add("第一页"); titles.add("第二页"); titles.add("第三页"); titles.add("第四页"); titles.add("第五页"); vpContent.setAdapter(new FragmentStatePagerAdapter(getSupportFragmentManager()) { @Override public Fragment getItem(int position) { return fragments.get(position); }@Override public int getCount() { return fragments.size(); }@Override public void destroyItem(ViewGroup container, int position, Object object) { super.destroyItem(container, position, object); }@Nullable @Override public CharSequence getPageTitle(int position) {return titles.get(position); } }); tlTabs.setupWithViewPager(vpContent); }private void initViews() { tlTabs = findViewById(R.id.tl_tabs); vpContent = findViewById(R.id.vp_content); }public static class MyFragment extends Fragment { String name; private TextView tvName; public MyFragment(String s) { name = s; }@Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment1, null); initViews(view); tvName.setText(name); return view; }private void initViews(View view) { tvName = view.findViewById(R.id.tvName); } } }
