viewpager的使用
效果图：
添加依赖包：
compile ‘com.android.support:design:22.2.0‘布局文件：
<?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" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <android.support.design.widget.TabLayout android:id="@+id/tabs" android:layout_width="match_parent" android:layout_height="wrap_content" app:tabIndicatorColor="@color/red" app:tabSelectedTextColor="@color/red" app:tabTextColor="@color/black"/> <!--可滑动的布局内容--> <android.support.v4.view.ViewPager android:id="@+id/vp_view" android:layout_width="match_parent" android:layout_height="wrap_content"/></LinearLayout>
页面代码：
public class FiveActivity extends Activity { private TabLayout mTabLayout; private ViewPager mViewPager; private LayoutInflater mInflater; private List<String> mTitleList = new ArrayList<>();//页卡标题集合 private View view1, view2, view3, view4, view5;//页卡视图 private List<View> mViewList = new ArrayList<>();//页卡视图集合 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_five); mViewPager = (ViewPager) findViewById(R.id.vp_view); mTabLayout = (TabLayout) findViewById(R.id.tabs); mInflater = LayoutInflater.from(this); view1 = mInflater.inflate(R.layout.activity_main, null); view2 = mInflater.inflate(R.layout.activity_main, null); view3 = mInflater.inflate(R.layout.activity_main, null); view4 = mInflater.inflate(R.layout.activity_main, null); view5 = mInflater.inflate(R.layout.activity_main, null); //添加页卡视图 mViewList.add(view1); mViewList.add(view2); mViewList.add(view3); mViewList.add(view4); mViewList.add(view5); //添加页卡标题 mTitleList.add("No:1"); mTitleList.add("No:2"); mTitleList.add("No:3"); mTitleList.add("No:4"); mTitleList.add("No:5"); mTabLayout.setTabMode(TabLayout.MODE_FIXED);//设置tab模式，当前为系统默认模式 mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(0)));//添加tab选项卡 mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(1))); mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(2))); mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(3))); mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(4))); MyPagerAdapter mAdapter = new MyPagerAdapter(mViewList); mViewPager.setAdapter(mAdapter);//给ViewPager设置适配器 mTabLayout.setupWithViewPager(mViewPager);//将TabLayout和ViewPager关联起来。 mTabLayout.setTabsFromPagerAdapter(mAdapter);//给Tabs设置适配器 } //ViewPager适配器 class MyPagerAdapter extends PagerAdapter { private List<View> mViewList; public MyPagerAdapter(List<View> mViewList) { this.mViewList = mViewList; } @Override public int getCount() { return mViewList.size();//页卡数 } @Override public boolean isViewFromObject(View view, Object object) { return view == object;//官方推荐写法 } @Override public Object instantiateItem(ViewGroup container, int position) { container.addView(mViewList.get(position));//添加页卡 return mViewList.get(position); } @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView(mViewList.get(position));//删除页卡 } @Override public CharSequence getPageTitle(int position) { return mTitleList.get(position);//页卡标题 } }}
