小編最近在做app的項(xiàng)目，需要用到tablayout實(shí)現(xiàn)頂部的滑動(dòng)效果，文中代碼用到了自定義item，代碼也很簡(jiǎn)單，感興趣的朋友跟隨腳本之家小編一起看看吧

最近需要做一個(gè)app，需要用到tablayout實(shí)現(xiàn)頂部的滑動(dòng)，用到了自定義item，不過(guò)沒(méi)有用到tabitem，貼出來(lái)供大家學(xué)習(xí)，先看圖吧，覺(jué)得滿意的繼續(xù)往下面看

具體代碼實(shí)現(xiàn):

我直接貼啦，能說(shuō)的不多

主布局: fragment_message.xml

<?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:orientation="vertical"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
 <!--
  app:tabIndicatorHeight="1dp" 指示器高度
  app:tabIndicatorColor="@color/white" 指示器顏色
  app:tabMode 默認(rèn)是fixed：固定的，標(biāo)簽很多時(shí)候會(huì)被擠壓，不能滑動(dòng)。
     scrollable 可滑動(dòng)伸縮式的
 -->
 <android.support.design.widget.TabLayout
  android:id="@+id/fg_mg_tab"
  android:layout_gravity="center"
  android:layout_width="match_parent"
  android:layout_height="@dimen/toolbar_height"
  android:background="@color/colorPrimary"
  app:tabIndicatorHeight="@dimen/common_dimension_2"
  app:tabMode="fixed"
  android:fillViewport="false"
  app:tabIndicatorColor="@color/green1"
  app:tabTextAppearance="@style/core_IconTabLayout"
  app:tabTextColor="@color/white"
  />
 <android.support.v4.view.ViewPager
  android:id="@+id/fg_mg_viewpager"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
 </android.support.v4.view.ViewPager>
</LinearLayout>

item布局: item_table_msg.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:gravity="center_vertical"
android:layout_height="wrap_content">
<ImageView
 android:id="@+id/iv_msg_tab"
 android:src="@drawable/ic_msg_find"
 android:scaleType="centerInside"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content" />
<TextView
 android:layout_marginLeft="@dimen/common_dimension_2"
 android:id="@+id/tv_msg_tab"
 android:textColor="@color/white"
 android:text="會(huì)話"
 android:textSize="@dimen/SmallerTextSize"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content" />
</LinearLayout>

適配器：MessagePagerAdapter

public class MessagePagerAdapter extends FragmentPagerAdapter {
 private final List<Pair<BaseFragment,MsgTabBean>> mFragmentList = new ArrayList<>();
 private Context mContext;
 public MessagePagerAdapter(Context mContext,FragmentManager fm) {
  super(fm);
  this.mContext = mContext;
 }
 public void addFlag(Pair<BaseFragment,MsgTabBean> msgTabBeanPair){
  mFragmentList.add(msgTabBeanPair);
 }
 @Override
 public Fragment getItem(int position) {
  return mFragmentList.get(position).first;
 }
 @Override
 public int getCount() {
  return mFragmentList.size();
 }
 public View getTabView(int position, ViewGroup mGroup){
  View view;
  view = LayoutInflater.from(mContext).inflate(R.layout.view_table_msg,mGroup,false);
  ImageView img = view.findViewById(R.id.iv_msg_tab);
  TextView tv = view.findViewById(R.id.tv_msg_tab);
  img.setImageResource(mFragmentList.get(position).second.getResId());
  tv.setText(mFragmentList.get(position).second.getTitle());
  return view;
 }
}

Fragment中進(jìn)行設(shè)置:

mMessagePagerAdapter = new MessagePagerAdapter(getActivity(),getActivity().getSupportFragmentManager());
  mMessagePagerAdapter.addFlag(new Pair<>(MsgFragmentFactory.getInstance().getMsgCommListFragment(),new MsgTabBean("通訊錄",R.drawable.ic_msg_comm_list)));
  mMessagePagerAdapter.addFlag(new Pair<>(MsgFragmentFactory.getInstance().getMsgCrowdFragment(),new MsgTabBean("群聊",R.drawable.ic_msg_crowd)));
  mMessagePagerAdapter.addFlag(new Pair<>(MsgFragmentFactory.getInstance().getMsgConverFragment(),new MsgTabBean("消息",R.drawable.ic_msg_conver)));
  mMessagePagerAdapter.addFlag(new Pair<>(MsgFragmentFactory.getInstance().getMsgFindFragment(),new MsgTabBean("發(fā)現(xiàn)",R.drawable.ic_msg_find)));
  mFgMgViewpager.setAdapter(mMessagePagerAdapter);
  mFgMgTab.setupWithViewPager(mFgMgViewpager);
  for (int index =0 ;index<mMessagePagerAdapter.getCount();index++){
   mFgMgTab.getTabAt(index).setCustomView(mMessagePagerAdapter.getTabView(index,mFgMgTab));
  }
  mFgMgViewpager.setOffscreenPageLimit(mMessagePagerAdapter.getCount());
  mFgMgViewpager.setCurrentItem(3);
 }
