注意要把垂直设置好,因为是linearLayout布局,漏掉了就不能滑动了
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.china.anonymous.viewpagedemotwo.MainActivity"> <android.support.design.widget.TabLayout android:id="@+id/tabs" app:tabIndicatorColor="@color/colorAccent" app:tabSelectedTextColor="@color/colorAccent" app:tabTextColor="@color/colorPrimaryDark" app:tabMode="fixed" android:layout_width="match_parent" android:layout_height="wrap_content"></android.support.design.widget.TabLayout> <android.support.v4.view.ViewPager android:id="@+id/viewPager" android:layout_width="match_parent" android:layout_height="wrap_content"></android.support.v4.view.ViewPager> </LinearLayout>
Fragment的布局文件,3个一样的:layout1.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:src="@mipmap/ic_launcher" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <TextView android:text="this is tab1111" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </LinearLayout>3个Fragment的文件,3个也是几乎一样的:注意,这里要导入的是import android.support.v4.app.Fragment;的fragment,而不是android.app.Fragment.因为ViewPager是import android.support.v4.app.Fragmentpackage com.china.anonymous.viewpagedemotwo; import android.os.Bundle;import android.support.annotation.Nullable;import android.support.v4.app.Fragment;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup; /** * Created by Anonymous on 2016/1/27. */public class Tab1 extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.layout1, null); return view; }}mainavtivity.javapackage com.china.anonymous.viewpagedemotwo; import android.os.Bundle;import android.support.design.widget.TabLayout;import android.support.v4.app.Fragment;import android.support.v4.view.ViewPager;import android.support.v7.app.AppCompatActivity; import java.util.ArrayList;import java.util.List; public class MainActivity extends AppCompatActivity { private TabLayout tabs; private ViewPager viewPager; private List<String> mTitle = new ArrayList<String>(); private List<Fragment> mFragment = new ArrayList<Fragment>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); MyAdapter adapter = new MyAdapter(getSupportFragmentManager(), mTitle, mFragment); viewPager.setAdapter(adapter); //为TabLayout设置ViewPager tabs.setupWithViewPager(viewPager); //使用ViewPager的适配器 tabs.setTabsFromPagerAdapter(adapter); } //初始化V private void initView() { tabs = (TabLayout) findViewById(R.id.tabs); viewPager = (ViewPager) findViewById(R.id.viewPager); mTitle.add("tab1"); mTitle.add("tab2"); mTitle.add("tab3"); mFragment.add(new Tab1()); mFragment.add(new Tab2()); mFragment.add(new Tab3()); }}MyAdapter.java要写上最后一个方法,为tagLayout配置上标题的package com.china.anonymous.viewpagedemotwo; import android.support.v4.app.Fragment;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentPagerAdapter; import java.util.List; public class MyAdapter extends FragmentPagerAdapter { private List<String> title; private List<Fragment> views; public MyAdapter(FragmentManager fm, List<String> title, List<Fragment> views) { super(fm); this.title = title; this.views = views; } @Override public Fragment getItem(int position) { return views.get(position); } @Override public int getCount() { return views.size(); } //配置标题的方法 @Override public CharSequence getPageTitle(int position) { return title.get(position); }}运行结果:
