Google官方在14年Google I/O上推出了全新的設(shè)計(jì)語言——Material Design碉咆。一并推出了一系列實(shí)現(xiàn)Material Design效果的控件庫——AndroidDesign Support Library。其中，有TabLayout, NavigationView,Floating labels for editing text,Floating Action Button,Snackbar, CoordinatorLayout, CollapsingToolbarLayout等等控件。在今后的學(xué)習(xí)中改化，我將一一介紹它們的特點(diǎn)和用法辨嗽。
我們可以使用三方開源的PagerSlidingTabStrip去實(shí)現(xiàn)猜扮，或者viewpagerindicator郎笆，我一般都偏向前者√饭＃現(xiàn)在我們可以使用Design support library庫的TabLayout去實(shí)現(xiàn)了。

一宛蚓、TabLayout基本使用 激捏。

1.在應(yīng)用的Build.gradle中添加support.design支持庫（注意：必須和v7包的版本相同）。

compile 'com.android.support:design:25.3.1'

2.TabLayout第一種使用–Tab固定模式凄吏。

Tab固定模式

1)創(chuàng)建布局文件activity_short_tab,在布局文件中添加TabLayout及ViewPager远舅。

<?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/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.linwei.lw.tablayoutdemo.ui.activity.MainActivity">

    <android.support.design.widget.TabLayout
        android:id="@+id/tab"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabIndicatorColor="@color/colorAccent"
        app:tabIndicatorHeight="2dp"
        app:tabMode="fixed"
        app:tabSelectedTextColor="@color/colorAccent">
    </android.support.design.widget.TabLayout>

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">
    </android.support.v4.view.ViewPager>

</LinearLayout>

2）定義一個(gè)FragmentFactivity的Fragment工廠類，專門生產(chǎn)Fragment對(duì)象（用了工廠類痕钢，方便Fragment使用图柏，提高了性能，在項(xiàng)目中很常見任连，記得在android5.0的Demo中也是怎么寫的蚤吹，可能有些讀者覺得沒必要，也可以每次去創(chuàng)建Fragment随抠，并添加到ViewPager中也可）裁着。

package com.linwei.lw.tablayoutdemo.ui.fragment;

import java.util.HashMap;

/**
 * Fragment工廠類。
 * Created by LW on 2017/4/20.
 */

public class FragmentFactory {
    private static HashMap<Integer, BaseFragment> mBaseFragments = new HashMap<Integer, BaseFragment>();

    public static BaseFragment createFragment(int pos) {
        BaseFragment baseFragment = mBaseFragments.get(pos);

        if (baseFragment == null) {
            switch (pos) {
                case 0:
                    baseFragment = new TopLineFragment();//頭條
                    break;
                case 1:
                    baseFragment = new NewsFragment();//要聞
                    break;
                case 2:
                    baseFragment = new EntertainmentFragment();//娛樂
                    break;
                case 3:
                    baseFragment = new SportsFragment();//體育
                    break;
                case 4:
                    baseFragment = new FinanceFragment();//財(cái)經(jīng)
                    break;
                case 5:
                    baseFragment = new ScienceFragment();//科技
                    break;
                case 6:
                    baseFragment = new ModeFragment();//時(shí)尚
                    break;
                case 7:
                    baseFragment = new VideoFragment();//視頻
                    break;
                case 8:
                    baseFragment = new  DirectSeedingFragment();//直播
                    break;

            }
            mBaseFragments.put(pos, baseFragment);
        }
        return baseFragment;
    }
}

3）定義一個(gè)Fragment的父類BaseFragment拱她，我就不解釋了看代碼二驰。

package com.linwei.lw.tablayoutdemo.ui.fragment;


import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

/**
 * Created by LW on 2017/4/20.
 */

public abstract class BaseFragment extends Fragment {

    protected Context mContent;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mContent = getContext();//上下文。
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return initView();//初始化布局秉沼。
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        loadData();//初始化數(shù)據(jù)桶雀。
    }

    protected abstract void loadData();

    protected abstract View initView();
}

4）BaseFragment的實(shí)現(xiàn)子類TopLineFragment，這里我就只列出一個(gè)子類代碼唬复，其他子類代碼也是一樣的矗积。

package com.linwei.lw.tablayoutdemo.ui.fragment;

import android.graphics.Color;
import android.view.Gravity;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

/**
 * Created by LW on 2017/4/21.
 */
public class TopLineFragment extends BaseFragment {
    @Override
    protected void loadData() {
        Toast.makeText(mContent,"Fragment頭條加載數(shù)據(jù)",Toast.LENGTH_SHORT).show();
    }

    @Override
    protected View initView() {
        TextView mView = new TextView(mContent);
        mView.setText("Fragment頭條");
        mView.setGravity(Gravity.CENTER);
        mView.setTextSize(18);
        mView.setTextColor(Color.BLACK);
        return mView;
    }
}

5）arrays.xml中第一顯示數(shù)據(jù)。我了方便使用盅抚，通過字符串?dāng)?shù)組定義起來漠魏。

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="tab_short_Title">
        <item>頭條</item>
        <item>要聞</item>
        <item>娛樂</item>
        <item>體育</item>
    </string-array>

    <string-array name="tab_long_Title">
        <item>頭條</item>
        <item>要聞</item>
        <item>娛樂</item>
        <item>體育</item>
        <item>財(cái)經(jīng)</item>
        <item>科技</item>
        <item>時(shí)尚</item>
        <item>視頻</item>
        <item>直播</item>
    </string-array>
</resources>

6）ShortTabActivity類，實(shí)現(xiàn)TabLayout和ViewPager的業(yè)務(wù)邏輯妄均。

package com.linwei.lw.tablayoutdemo.ui.activity;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
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 com.linwei.lw.tablayoutdemo.R;
import com.linwei.lw.tablayoutdemo.Utils.CommentUtils;
import com.linwei.lw.tablayoutdemo.ui.fragment.BaseFragment;
import com.linwei.lw.tablayoutdemo.ui.fragment.FragmentFactory;

public class ShortTabActivity extends AppCompatActivity {
    private TabLayout mTab;
    private ViewPager mViewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_short_tab);
        initView();
        initData();
    }

    private void initData() {
        ShortPagerAdapter adapter = new ShortPagerAdapter(getSupportFragmentManager());
        mViewPager.setAdapter(adapter);
        mTab.setupWithViewPager(mViewPager);

    }

    private void initView() {
        mTab = (TabLayout) findViewById(R.id.tab);
        mViewPager = (ViewPager) findViewById(R.id.viewpager);
    }

    private class ShortPagerAdapter extends FragmentPagerAdapter {
        public String[] mTilte;

        public ShortPagerAdapter(FragmentManager fm) {
            super(fm);
            mTilte = getResources().getStringArray(R.array.tab_short_Title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mTilte[position];
        }

        @Override
        public BaseFragment getItem(int position) {
            BaseFragment fragment = FragmentFactory.createFragment(position);
            return fragment;
        }

        @Override
        public int getCount() {
            return CommentUtils.TAB_SHORT_COUNT;
        }
    }
}

TabLayout其他模式柱锹，我就不一一介紹，這里有Demo和CSDN詳細(xì)文章丰包。
