横向滑动

注:要有两个类，，一个是main主类，，然后一个是Fragment

布局也是两个

主布局控件代码是：

<RelativeLayout 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"
    tools:context="com.example.com.henxianhuadong.MainActivity">

   
    <!--横向滑动菜单-->
    <android.support.design.widget.TabLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:id="@+id/tl"
        app:tabGravity="center"
        app:tabIndicatorColor="#fff"
        app:tabMode="scrollable"
        app:tabSelectedTextColor="@color/colorPrimary"
        app:tabTextColor="@color/colorPrimary"></android.support.design.widget.TabLayout>


    <android.support.v4.view.ViewPager
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/vp"
        android:layout_below="@id/tl"></android.support.v4.view.ViewPager>
</RelativeLayout>

字布局文件中是：

<RelativeLayout 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"
    tools:context="com.example.com.henxianhuadong.Fragment01">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#f00"
        android:textSize="100sp"
        android:text="asdas"
        android:id="@+id/tv"/>

mainActivity中的代码是：

import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.LinearLayout;
import android.widget.TableLayout;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

    private LinearLayout ll;
    private List<String> tabMenu;
    private ViewPager vp;
    private TabLayout tl;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tl = findViewById(R.id.tl);
        vp = findViewById(R.id.vp);


        getData();


        vp.setAdapter(new MyAdapter(getSupportFragmentManager()));
//将tabLayout组件于ViewPage组件进行关联
        tl.setupWithViewPager(vp);
    }

    private void getData() {
        tabMenu=new ArrayList<>();
        tabMenu.add("推荐");
        tabMenu.add("新时达");
        tabMenu.add("热点");
        tabMenu.add("北京");
        tabMenu.add("视频");
        tabMenu.add("娱乐");
        tabMenu.add("图片");
        tabMenu.add("问答");
        tabMenu.add("科技");
        tabMenu.add("汽车");
    }
class MyAdapter extends FragmentPagerAdapter{

     public MyAdapter(FragmentManager fm) {
        super(fm);
    }
//返回页面的标题
    @Override
    public CharSequence getPageTitle(int position) {
        return tabMenu.get(position);
    }

    @Override
    public Fragment getItem(int position) {
        Fragment01 fragment = new Fragment01();
        //传值
        Bundle bundle = new Bundle();
        bundle.putString("data",tabMenu.get(position));
        fragment.setArguments(bundle);
        return fragment;
    }

    @Override
    public int getCount() {
        return tabMenu.size();
    }
}
}

Fragment中的代码是：

import android.support.annotation.Nullable;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class Fragment01 extends Fragment{

    private View view;
    private TextView tv;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.activity_fragment,container,false);
        tv = view.findViewById(R.id.tv);
        Bundle arguments = getArguments();
        String data = arguments.getString("data");
        tv.setText(data);
        return view;
    }
}
