【中文标题】Android TabLayout Android 设计【英文标题】：Android TabLayout Android Design 【发布时间】：2015-08-12 22:07:25 【问题描述】：我正在尝试让 android 设计库中的新 TabLayout 正常工作。
我正在关注这篇文章：
http://android-developers.blogspot.com/2015/05/android-design-support-library.html
和文档：
http://developer.android.com/reference/android/support/design/widget/TabLayout.html
并且在我的活动中提出了以下代码，但是当我运行活动时，tablayout 没有显示。
我尝试在活动布局文件中添加，但它说找不到那个 xml 标签。
public class TabActivity extends BaseActivity
SectionPagerAdapter mSectionsPagerAdapter;
ViewPager mViewPager;
@Override
public void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tab);
LinearLayout v = (LinearLayout)findViewById(R.id.tabContainer);
TabLayout tabLayout = new TabLayout(this);
tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));
tabLayout.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, 50));
v.addView(tabLayout);
mSectionsPagerAdapter = new SectionPagerAdapter(getFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
tabLayout.setupWithViewPager(mViewPager);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
public class SectionPagerAdapter extends FragmentPagerAdapter
private String TAG = "SectionPagerAdapter";
public SectionPagerAdapter(FragmentManager fm)
super(fm);
@Override
public Fragment getItem(int position)
return new Fragment();
@Override
public int getCount()
return 2;
@Override
public CharSequence getPageTitle(int position)
Locale l = Locale.getDefault();
switch (position)
case 0:
return "test";
case 1:
return "test";
case 2:
return null;
将以下内容添加到我的 gradle 文件中
compile 'com.android.support:design:22.2.0'
【问题讨论】：
我发现这篇很好的演练文章.. github.com/codepath/android_guides/wiki/… 我刚刚发布了一个关于选项卡式 ViewPager 的教程，它为每个选项卡提供了单独的后退导航。这对你来说可能也很有趣：medium.com/@nilan/… 【参考方案1】：我刚刚设法设置了新的 TabLayout，所以这里是执行此操作的快速步骤 (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
在 build.gradle 文件中添加依赖项：
dependencies
compile 'com.android.support:design:23.1.1'
在布局中添加 TabLayout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_
android:layout_
android:background="?attr/colorPrimary"/>
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_
android:layout_/>
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_
android:layout_/>
</LinearLayout>
像这样设置你的活动：
import android.os.Bundle;
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.support.v7.widget.Toolbar;
public class TabLayoutActivity extends AppCompatActivity
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pull_to_refresh);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
if (toolbar != null)
setSupportActionBar(toolbar);
viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
tabLayout.setupWithViewPager(viewPager);
public class SectionPagerAdapter extends FragmentPagerAdapter
public SectionPagerAdapter(FragmentManager fm)
super(fm);
@Override
public Fragment getItem(int position)
switch (position)
case 0:
return new FirstTabFragment();
case 1:
default:
return new SecondTabFragment();
@Override
public int getCount()
return 2;
@Override
public CharSequence getPageTitle(int position)
switch (position)
case 0:
return "First Tab";
case 1:
default:
return "Second Tab";
【讨论】：
看起来不错！是否需要编译'com.android.support:recyclerview-v7:22.2.0'？我想我只是错过了将它添加到我的布局中。 如何在 TabLayout 中添加自定义字体？？ @DroidLearner 如果您想自定义标签而不是更改文本颜色或图标，您可以在将标签添加到 TabLayout 小部件时使用 setCustomView() 方法。 developer.android.com/reference/android/support/design/widget/… 我使用相同的设置，一切都很好，当我滑动页面时，tablayout 总是更新。但是当我选择一个选项卡时，片段并不总是更新。 30% 的时间它停留在同一页面上。难道我做错了什么？或者这是一个新的错误。 现在我用方法应该做的三件事替换了tabLayout.setupWithViewPager(viewPager);，将OnTabSelectListener添加到TabLayout，从PagerAdapter填充选项卡，并在@上添加addOnPageChangeListener 987654330@。所以现在它工作正常。但是正如 API 文档中提到的那样 tabLayout.setupWithViewPager(viewPager); 做了这三件事，当我自己做这些事情时，它工作得很好，但是用那一行它似乎是不可靠的。【参考方案2】：
我必须从各种来源收集信息来组合一个功能正常的 TabLayout。以下是一个完整的用例，可以根据需要进行修改。
确保模块 build.gradle 文件包含对 com.android.support:design 的依赖项。
dependencies
compile 'com.android.support:design:23.1.1'
在我的例子中，我正在使用 TabLayout 在应用程序中创建一个 About 活动。我将以下部分添加到AndroidMainifest.xml。设置 parentActivityName 允许 home 箭头将用户带回主要活动。
<!-- android:configChanges="orientation|screenSize" makes the activity not reload when the orientation changes. -->
<activity
android:name=".AboutActivity"
android:label="@string/about_app"
android:theme="@style/MyApp.About"
android:parentActivityName=".MainActivity"
android:configChanges="orientation|screenSize" >
<!-- android.support.PARENT_ACTIVITY is necessary for API <= 15. -->
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value=".MainActivity" />
</activity>
styles.xml 包含以下条目。这个应用程序的主要活动有一个白色的 AppBar，关于关于活动的蓝色 AppBar。我们需要为 About Activity 设置colorPrimaryDark，以便 AppBar 上方的状态栏为蓝色。
<style name="MyApp" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorAccent">@color/blue</item>
</style>
<style name="MyApp.About" />
<!-- ThemeOverlay.AppCompat.Dark.ActionBar" makes the text and the icons in the AppBar white. -->
<style name="MyApp.DarkAppBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="MyApp.AppBarOverlay" parent="ThemeOverlay.AppCompat.ActionBar" />
<style name="MyApp.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
还有一个styles.xml (v19)。它位于src/main/res/values-v19/styles.xml。仅当设备的 API >= 19 时才应用此文件。
<!-- android:windowTranslucentStatus requires API >= 19. It makes the system status bar transparent.
When it is specified the root layout should include android:fitsSystemWindows="true".
colorPrimaryDark goes behind the status bar, which is then darkened by the overlay. -->
<style name="MyApp.About">
<item name="android:windowTranslucentStatus">true</item>
<item name="colorPrimaryDark">@color/blue</item>
</style>
AboutActivity.java 包含以下代码。就我而言，我有固定数量的选项卡 (7)，因此我可以删除所有处理动态选项卡的代码。
import android.os.Bundle;
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.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
public class AboutActivity extends AppCompatActivity
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.about_coordinatorlayout);
// We need to use the SupportActionBar from android.support.v7.app.ActionBar until the minimum API is >= 21.
Toolbar supportAppBar = (Toolbar) findViewById(R.id.about_toolbar);
setSupportActionBar(supportAppBar);
// Display the home arrow on supportAppBar.
final ActionBar appBar = getSupportActionBar();
assert appBar != null;// This assert removes the incorrect warning in Android Studio on the following line that appBar might be null.
appBar.setDisplayHomeAsUpEnabled(true);
// Setup the ViewPager.
ViewPager aboutViewPager = (ViewPager) findViewById(R.id.about_viewpager);
assert aboutViewPager != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutViewPager might be null.
aboutViewPager.setAdapter(new aboutPagerAdapter(getSupportFragmentManager()));
// Setup the TabLayout and connect it to the ViewPager.
TabLayout aboutTabLayout = (TabLayout) findViewById(R.id.about_tablayout);
assert aboutTabLayout != null; // This assert removes the incorrect warning in Android Studio on the following line that aboutTabLayout might be null.
aboutTabLayout.setupWithViewPager(aboutViewPager);
public class aboutPagerAdapter extends FragmentPagerAdapter
public aboutPagerAdapter(FragmentManager fm)
super(fm);
@Override
// Get the count of the number of tabs.
public int getCount()
return 7;
@Override
// Get the name of each tab. Tab numbers start at 0.
public CharSequence getPageTitle(int tab)
switch (tab)
case 0:
return getString(R.string.version);
case 1:
return getString(R.string.permissions);
case 2:
return getString(R.string.privacy_policy);
case 3:
return getString(R.string.changelog);
case 4:
return getString(R.string.license);
case 5:
return getString(R.string.contributors);
case 6:
return getString(R.string.links);
default:
return "";
@Override
// Setup each tab.
public Fragment getItem(int tab)
return AboutTabFragment.createTab(tab);
AboutTabFragment.java 用于填充每个选项卡。在我的例子中，第一个选项卡在 ScrollView 内有一个 LinearLayout，所有其他选项卡都有一个 WebView 作为根布局。
import android.os.Build;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.widget.TextView;
public class AboutTabFragment extends Fragment
private int tabNumber;
// AboutTabFragment.createTab stores the tab number in the bundle arguments so it can be referenced from onCreate().
public static AboutTabFragment createTab(int tab)
Bundle thisTabArguments = new Bundle();
thisTabArguments.putInt("Tab", tab);
AboutTabFragment thisTab = new AboutTabFragment();
thisTab.setArguments(thisTabArguments);
return thisTab;
@Override
public void onCreate (Bundle savedInstanceState)
super.onCreate(savedInstanceState);
// Store the tab number in tabNumber.
tabNumber = getArguments().getInt("Tab");
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
View tabLayout;
// Load the about tab layout. Tab numbers start at 0.
if (tabNumber == 0)
// Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
// The fragment will take care of attaching the root automatically.
tabLayout = inflater.inflate(R.layout.about_tab_version, container, false);
else // load a WebView for all the other tabs. Tab numbers start at 0.
// Setting false at the end of inflater.inflate does not attach the inflated layout as a child of container.
// The fragment will take care of attaching the root automatically.
tabLayout = inflater.inflate(R.layout.about_tab_webview, container, false);
WebView tabWebView = (WebView) tabLayout;
switch (tabNumber)
case 1:
tabWebView.loadUrl("file:///android_asset/about_permissions.html");
break;
case 2:
tabWebView.loadUrl("file:///android_asset/about_privacy_policy.html");
break;
case 3:
tabWebView.loadUrl("file:///android_asset/about_changelog.html");
break;
case 4:
tabWebView.loadUrl("file:///android_asset/about_license.html");
break;
case 5:
tabWebView.loadUrl("file:///android_asset/about_contributors.html");
break;
case 6:
tabWebView.loadUrl("file:///android_asset/about_links.html");
break;
default:
break;
return tabLayout;
about_coordinatorlayout.xml如下：
<!-- android:fitsSystemWindows="true" moves the AppBar below the status bar.
When it is specified the theme should include <item name="android:windowTranslucentStatus">true</item>

android:id="@+id/about_viewpager"
android:layout_
android:layout_
android:layout_weight="1" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
about_tab_version.xml如下：
<!-- The ScrollView allows the LinearLayout to scroll if it exceeds the height of the page. -->
<ScrollView
android:id="@+id/about_version_scrollview"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_

android:layout_
android:layout_
android:orientation="vertical"
android:padding="16dp" >
<!-- Include whatever content you want in this tab here. -->
</LinearLayout>
</ScrollView>
还有about_tab_webview.xml：
<!-- This WebView displays inside of the tabs in AboutActivity. -->
<WebView
android:id="@+id/about_tab_webview"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_
android:layout_ />
strings.xml也有条目
<string name="about_app">About App</string>

还有colors.xml
<color name="blue">#FF1976D2</color>
<color name="light_blue">#FFBBDEFB</color>
<color name="white">#FFFFFFFF</color>
src/main/assets 包含AboutTabFragemnt.java 中引用的 HTML 文件。
【讨论】：
你从哪里得到 getString 方法？ @RichArt getString 是标准 Android 上下文的公共方法。 developer.android.com/reference/android/content/… 根据您编写代码的位置，您可能需要使用getResources.getString()。【参考方案3】：
当 ViewPager 中的片段更改时，我遇到了一些菜单更改问题。我最终实现了下面的代码。

public int getModulePosition(EnumUtils.Module moduleName)
for(int x = 0 ; x < moduleList.size() ; x++)
if(moduleList.get(x).equals(moduleName))

return -1;
并在onCreate中的FragmentsetHasOptionMenu(true)的每一页中实现onCreateOptionMenu。然后它将正常工作。

【参考方案4】：我尝试解决这里是我的代码。
首先在 build.gradle(app) 中添加依赖。
dependencies
compile 'com.android.support:design:23.1.1'
创建PagerAdapter.class
public class PagerAdapter extends FragmentPagerAdapter
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public PagerAdapter(FragmentManager manager)
super(manager);
@Override
public Fragment getItem(int position)
Log.i("PosTabItem",""+position);
return mFragmentList.get(position);
@Override
public int getCount()
return mFragmentList.size();
public void addFragment(Fragment fragment, String title)
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
@Override
public CharSequence getPageTitle(int position)
Log.i("PosTab",""+position);
return mFragmentTitleList.get(position);
创建activity_main.xml
<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:id="@+id/main_layout"
android:layout_
android:layout_
tools:context=".MainActivity">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_
android:layout_
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_
android:layout_
android:layout_below="@+id/toolbar"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_
android:layout_
android:layout_below="@id/tab_layout" />
</RelativeLayout>
创建MainActivity.class
public class MainActivity extends AppCompatActivity
Pager pager;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
pager = new Pager(getSupportFragmentManager());
pager.addFragment(new FragmentOne(), "One");
viewPager.setAdapter(pager);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setTabMode(TabLayout.MODE_FIXED);
tabLayout.setSmoothScrollingEnabled(true);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener()
@Override
public void onTabSelected(TabLayout.Tab tab)
viewPager.setCurrentItem(tab.getPosition());
@Override
public void onTabUnselected(TabLayout.Tab tab)
@Override
public void onTabReselected(TabLayout.Tab tab)
);
最后创建片段以添加到 viewpager
crate fragment_one.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_
android:layout_>
<TextView
android:text="Location"
android:layout_
android:layout_ />
</LinearLayout>
创建FragmentOne.class
public class FragmentOne extends Fragment
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
View view = inflater.inflate(R.layout.fragment_one, container,false);
return view;

【参考方案6】：这么简单的方法：
XML：
<android.support.design.widget.TabLayout
android:id="@+id/tab_layout"
android:layout_
android:layout_
android:background="#fff"/>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_
android:layout_/>
Java 代码：
private ViewPager viewPager;
private String[] PAGE_TITLES = new String[]
"text1",
"text1",
"text3"
;
private final Fragment[] PAGES = new Fragment[]
new fragment1(),
new fragment2(),
new fragment3()
;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_a_requests);
/**TODO ***************tebLayout*************************/
viewPager = findViewById(R.id.viewpager);
viewPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
TabLayout tabLayout = findViewById(R.id.tab_layout);
tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#1f57ff"));
tabLayout.setSelectedTabIndicatorHeight((int) (4 *
getResources().getDisplayMetrics().density));
tabLayout.setTabTextColors(Color.parseColor("#9d9d9d"),
Color.parseColor("#0d0e10"));
tabLayout.setupWithViewPager(viewPager);

【参考方案7】：将此添加到模块 build.gradle：
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
