来源：互联网发布：linux 禅道下载地址编辑：程序博客网时间：2024/06/05 22:38

1.在gradle引入design库

compile 'com.android.support:appcompat-v7:23.4.0'compile 'com.android.support:design:23.4.0'

2.主页面布局

<?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" >    <android.support.design.widget.TabLayout        android:id="@+id/sliding_tabs"        android:layout_width="match_parent"        android:layout_height="wrap_content"        />    <TextView    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="Hello World!" />    <android.support.v4.view.ViewPager    android:id="@+id/viewpager"    android:layout_width="match_parent"    android:layout_height="0px"    android:layout_weight="1"    android:background="@android:color/white" /></LinearLayout>

3.adapter布局

<?xml version="1.0" encoding="utf-8"?><TextView    xmlns:android="http://schemas.android.com/apk/res/android"      android:layout_width="match_parent"       android:layout_height="match_parent"    android:gravity="center"    />

4.adapter代码

public class SimpleFragmentAdapter extends FragmentPagerAdapter {    final int PAGE_COUNT = 3;    private String tabTitles[]  = new String[]{"tabl","tab2","tab2"};    private Context context;    public SimpleFragmentAdapter(FragmentManager fm,Context context) {        super(fm);        this.context = context;    }    @Override    public Fragment getItem(int position) {        return fragment.getInstance(position);    }    @Override    public int getCount() {        return PAGE_COUNT;    }    @Override    public CharSequence getPageTitle(int position) {        return tabTitles[position];    }}

5.framgent代码

public class fragment extends Fragment {    public static  String tag = "fragment";    private int num;    public static fragment getInstance(int num){        Bundle bundle = new Bundle();        bundle.putInt(tag,num);        fragment fg = new fragment();        fg.setArguments(bundle);        return fg;    }    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        num = getArguments().getInt(tag);    }    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {        View view = inflater.inflate(R.layout.fragment_content, container, false);        TextView tv = (TextView)view;        tv.setText("Fragment++"+num);        return view;    }

6.MainActivity代码

public class MainActivity extends AppCompatActivity {    private SimpleFragmentAdapter fragmentAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        fragmentAdapter = new SimpleFragmentAdapter(getSupportFragmentManager(), this);        ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);        viewPager.setAdapter(fragmentAdapter);        TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);        tabLayout.setupWithViewPager(viewPager);        tabLayout.setTabMode(TabLayout.MODE_FIXED);    }}

7，综上所述就实现了TabLayout最简单的用法了。
