　　这里就说下tablayout+viewpager的实现方式；tablayout是android5.0推出来的一个MaterialDesign风格的控件，是专门用来实现tab栏效果的；功能强大，使用方便灵活；

一、引入依赖库

使用非常方便,Android Studio只需要在gradle中引入即可使用 .

apply plugin: 'com.android.application'

android {

    compileSdkVersion 28

    defaultConfig {

        applicationId "com.example.panzq.tablayout"

        minSdkVersion 22

        targetSdkVersion 28

        versionCode 1

        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {

        release {

            minifyEnabled false

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }

    }

}

dependencies {

    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'

    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    testImplementation 'junit:junit:4.12'

    androidTestImplementation 'com.android.support.test:runner:1.0.2'

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.android.support:design:28.0.0'

    implementation 'com.android.support:recyclerview-v7:28.0.0'

    implementation 'com.android.support:support-v4:28.0.0'

}

二、layout中定义TabLayout控件及ViewPager控件

<!-- 
app:tabGravity="center" 对齐方式，可选fill和center 
app:tabIndicatorColor="@color/colorAccent" 设置tab下划线的颜色 
app:tabMode="scrollable" scrollable是可以横行滚动,fixed是指固定个数 
app:tabSelectedTextColor="@color/colorPrimaryDark" 选择tab的文本颜色 
app:tabTextColor="@color/colorPrimary" 普通tab字体颜色

app:tabIndicatorHeight 指示器高度
app:tabBackground tab背景颜色
app:tabMaxWidth tab栏最大宽度
app:tabTextAppearance tab栏字体样式
app:tabMinWidth tab栏最小宽度

-->

<?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:id="@+id/linear"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical"

    tools:context=".MainActivity">

    <android.support.v4.view.ViewPager

        android:id="@+id/viewPager"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <android.support.design.widget.TabLayout

            android:id="@+id/tabLayout"

            android:layout_width="match_parent"

            android:layout_height="wrap_content"

            app:tabBackground="@color/colorPrimary"

            app:tabGravity="fill"

            app:tabMode="scrollable"

            app:tabSelectedTextColor="@color/colorAccent"

            app:tabIndicatorColor="@color/colorPrimaryLight"

            app:tabTextColor="#ffffff">

            <android.support.design.widget.TabItem

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:icon="@drawable/ic_call_black_24dp"

                android:text="@string/recents" />

            <android.support.design.widget.TabItem

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:icon="@drawable/ic_star_border_black_24dp"

                android:text="@string/favourite" />

            <android.support.design.widget.TabItem

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:icon="@drawable/ic_person_black_24dp"

                android:text="@string/contacts" />

            <android.support.design.widget.TabItem

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:icon="@drawable/ic_dialpad_black_24dp"

                android:text="@string/keypad" />

            <android.support.design.widget.TabItem

                android:layout_width="wrap_content"

                android:layout_height="wrap_content"

                android:icon="@drawable/ic_voicemail_black_24dp"

                android:text="@string/voicemail" />

        </android.support.design.widget.TabLayout>

    </android.support.v4.view.ViewPager>

</LinearLayout>

三设置TabLayout和ViewPager关联

MainActivity

public class MainActivity extends AppCompatActivity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        TabLayout tabLayout = findViewById(R.id.tabLayout);

        ViewPager viewPager = findViewById(R.id.viewPager);

        CallPagerAdapter callPagerAdapter = new CallPagerAdapter(getSupportFragmentManager());

        callPagerAdapter.addFragment(new RecentCallFragment(), "RECENT");

        callPagerAdapter.addFragment(new FavouriteCallFragment(), "FAVOURITE");

        callPagerAdapter.addFragment(new ContactCallFragment(), "CONTACTS");

        callPagerAdapter.addFragment(new KeypadCallFragment(), "KEYPAD");

        callPagerAdapter.addFragment(new VoicemailCallFragment(), "VOICEMAIL");

        viewPager.setAdapter(callPagerAdapter);

        tabLayout.setupWithViewPager(viewPager);

        tabLayout.getTabAt(0).setIcon(R.drawable.ic_call_black_24dp);

        tabLayout.getTabAt(1).setIcon(R.drawable.ic_star_border_black_24dp);

        tabLayout.getTabAt(2).setIcon(R.drawable.ic_person_black_24dp);

        tabLayout.getTabAt(3).setIcon(R.drawable.ic_dialpad_black_24dp);

        tabLayout.getTabAt(4).setIcon(R.drawable.ic_voicemail_black_24dp);

    }

}

　　需要注意的是setupWithViewPager();方法的调用必须在viewpager设置完适配器后调用，如果在设置适配器之前调用会抛异常，至于为什么会抛异常，后面tablayout的源码会说到；这样tab栏切换效果就实现了。

如果发现程序出现如下错误

    Process: com.example.panzq.tablayout, PID:

则需要修改style.xml文件

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

改为

<style name="AppTheme" parent="Theme.MaterialComponents.Light.DarkActionBar">
