android洪洋csdn,TabLayout让Fragment在ViewPager中的滑动切换更优雅

首先扯点别的：最近感觉自己腐败了，学习也没劲了，锻炼也不积极了，整天吹牛扯淡，意志渐渐消磨，理想慢慢模糊，眼看就要堕入混吃等死的地步了。但是，经过痛苦的挣扎，激烈的内心斗争，我还是决定依然往前走，去迎接生命中的挑战与逆境，欢乐与惊喜。“弃我去者，昨日之日不可留。”今天就应该战斗，努力坚持，为了自己的理想，为了自己的责任。

今天是说一个Android Design Support Library中的TabLayout,我是在洪洋的一篇博客中看到的，网址：http://blog.csdn.net/lmj623565791/article/details/38902805。

进入正题之前想问一问谁知道怎么用简单的方法生成gif图片啊，也是艰难，效果图只能是静态的。

不会制作gif图片也是艰难，效果不好，接下来看看代码吧，我是用的是android studio

第一 看看 build.gradle文件，要在dependencies｛｝中添加一行compile ‘com.android.support:design:23.2.0’

apply plugin: 'com.android.application'

android {

compileSdkVersion 23

buildToolsVersion "23.0.3"

defaultConfig {

applicationId "com.dmw.tablayoutviewpagerdemo"

minSdkVersion 14

targetSdkVersion 23

versionCode 1

versionName "1.0"

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

}

}

dependencies {

compile fileTree(include: ['*.jar'], dir: 'libs')

testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:23.2.1'

compile 'com.android.support:design:23.2.0'

}

第二：activity_main.xml文件

第三MainActivity.java文件

package com.dmw.tablayoutviewpagerdemo;

import android.graphics.Color;

import android.support.design.widget.TabLayout;

import android.support.v4.app.Fragment;

import android.support.v4.app.FragmentPagerAdapter;

import android.support.v4.view.ViewPager;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import java.util.ArrayList;

import java.util.List;

public class MainActivity extends AppCompatActivity {

private TabLayout tabLayout;

private ViewPager viewPager;

private List fragments;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//设置tabLayout的属性

tabLayout = (TabLayout) findViewById(R.id.tabLayout);

tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

tabLayout.setTabMode(TabLayout.MODE_FIXED);

tabLayout.setBackgroundColor(Color.parseColor("#ffffff"));

tabLayout.setTabTextColors(Color.parseColor("#000000"),Color.parseColor("#0ddcff") );//设置tab上文字的颜色，第一个参数表示没有选中状态下的文字颜色，第二个参数表示选中后的文字颜色

tabLayout.setSelectedTabIndicatorColor(Color.parseColor("#0ddcff"));//设置tab选中的底部的指示条的颜色

viewPager = (ViewPager) findViewById(R.id.viewPager);

fragments=new ArrayList<>();

//给fragments 添加三个fragment

fragments.add(new Fragmnet1());

fragments.add(new Fragment2());

fragments.add(new Fragment3());

//给viewPager设置适配器

viewPager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {

@Override

public Fragment getItem(int position) {

return fragments.get(position);

}

@Override

public int getCount() {

return fragments.size();

}

@Override

public CharSequence getPageTitle(int position) {

switch (position) {

case 0:

return "fragment1 Title";

case 1:

return "fragment2 Title";

case 2:

return "fragment3 Title";

}

return null;

}

});

//然后让TabLayout和ViewPager关联，只需要一句话，简直也是没谁了.

tabLayout.setupWithViewPager(viewPager);

}

}

三个Fragment及其xml文件

Fragment1.java

package com.dmw.tablayoutviewpagerdemo;

import android.os.Bundle;

import android.support.annotation.Nullable;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ArrayAdapter;

import android.widget.ListView;

import java.util.ArrayList;

import java.util.List;

/** * Created by Administrator on 2016/4/6. */

public class Fragmnet1 extends Fragment {

private View view;

private ListView listView;

private Listlist;

private ArrayAdapter adapter;

@Override

public void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

list=new ArrayList<>();

for(int i=0;i<50;i++){

list.add("listView item "+i);

}

}

@Nullable

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

view=inflater.inflate(R.layout.fragment1,container,false);

listView= (ListView) view.findViewById(R.id.listView);

adapter=new ArrayAdapter(getActivity(),android.R.layout.simple_list_item_1,list);

listView.setAdapter(adapter);

return view;

}

}

fragment1.xml

Fragment2.java和Fragment3.java都一样

package com.dmw.tablayoutviewpagerdemo;

import android.os.Bundle;

import android.support.annotation.Nullable;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.TextView;

import android.widget.Toast;

/** * Created by Administrator on 2016/4/6. */

public class Fragment2 extends Fragment {

private View view;

private TextView textView;

@Nullable

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

view=inflater.inflate(R.layout.fragment2,container,false);

textView= (TextView) view.findViewById(R.id.textView2);

textView.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

Toast.makeText(getActivity(),"i am Fragment2",Toast.LENGTH_SHORT).show();

}

});

return view;

}

}

fragment2和fragment3.xml 两者只有textview的id不一样

行，效果有了，代码也贴了，工程的完整代码链接http://download.csdn.net/detail/leilifengxingmw/9482257

结尾：android 新特性自己了解的很少，自己要多多关注，坚持学下去！也希望和我一样的android小白，不放弃，不抛弃，坚持学习，终会有收获！
