效果图如下
首先,要使用控件需要添加design library,在Android Studio中添加
compile ‘com.android.support:design:23.4.0‘
然后是布局文件
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" xmlns:app="http://schemas.android.com/apk/res-auto" tools:context="com.lg.tablayoutdemo.MainActivity"> <android.support.design.widget.TabLayout android:id="@+id/tab_layou" android:layout_width="match_parent" app:tabIndicatorColor="@android:color/holo_blue_light" app:tabTextColor="@android:color/darker_gray" app:tabSelectedTextColor="@android:color/black" android:layout_height="wrap_content" /> <android.support.v4.view.ViewPager android:id="@+id/view_pager" android:layout_below="@id/tab_layou" android:layout_width="match_parent" android:layout_height="match_parent" /> </RelativeLayout>
其中TabLayout中tabIndicatorColor属性为标签底部下滑线颜色,tabTextColor为标签未选中时字体颜色,tabSelectedTextColor为选中时字体颜色
自定一个FragmentPagerAdapter适配器
public class MyViewPagerAdapter extends FragmentPagerAdapter { private List<Fragment> fragments; private String[] titles; public MyViewPagerAdapter(FragmentManager fm, String[] titles, List<Fragment> fragments) { super(fm); this.titles = titles; this.fragments = fragments; } @Override public Fragment getItem(int arg0) { return fragments.get(arg0); } @Override public CharSequence getPageTitle(int position) { return titles[position]; } @Override public int getCount() { return fragments.size(); } }
Fragment代码我就不贴了,会在下面奉上源码地址
public class MainActivity extends AppCompatActivity implements TabLayout.OnTabSelectedListener { private TabLayout tabLayout; private ViewPager viewPager; private MyViewPagerAdapter viewPagerAdapter; //TabLayout标签 private String[] titles=new String[]{"ANDROID","JAVA","C#","PHP"}; private List<Fragment> fragments=new ArrayList<>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); init(); } private void init(){ tabLayout=(TabLayout)findViewById(R.id.tab_layou); viewPager=(ViewPager)findViewById(R.id.view_pager); //设置TabLayout标签的显示方式 tabLayout.setTabMode(TabLayout.MODE_FIXED); //循环注入标签 for (String tab:titles){ tabLayout.addTab(tabLayout.newTab().setText(tab)); } //设置TabLayout点击事件 tabLayout.setOnTabSelectedListener(this); fragments.add(new AndroidFragment()); fragments.add(new JavaFragment()); fragments.add(new CshapFragment()); fragments.add(new PhpFragment()); viewPagerAdapter=new MyViewPagerAdapter(getSupportFragmentManager(),titles,fragments); viewPager.setAdapter(viewPagerAdapter); tabLayout.setupWithViewPager(viewPager); } @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) { } }
以上是核心代码,至此功能就实现了,当然也可 以根据不同的需求进行改动
