本文实例为大家分享了ViewPage+Fragment仿微信界面的具体代码，供大家参考，具体内容如下

实现效果：

左右滑动可切换界面，点击也可以实现

界面与碎片：

主界面：

<?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:layout_width="match_parent" 
 android:layout_height="match_parent" 
 android:orientation="vertical" 
 tools:context="com.example.g160628_android10_viewpagerfragment_zuoye.MainActivity"> 
 <!--设置ViewPager与单选组--> 
 <android.support.v4.view.ViewPager 
  android:layout_width="match_parent" 
  android:layout_height="wrap_content" 
  android:id="@+id/vp_main_view" 
  android:layout_weight="1" 
  ></android.support.v4.view.ViewPager> 
 <RadioGroup 
  android:layout_width="match_parent" 
  android:layout_height="wrap_content" 
  android:orientation="horizontal" 
  android:id="@+id/rg_main_group" 
  > 
  <RadioButton 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:layout_weight="1" 
   android:button="@null" 
   android:background="@drawable/button_selector" 
   android:id="@+id/rb_main_bu1" 
   /> 
  <RadioButton 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:layout_weight="1" 
   android:button="@null" 
   android:background="@drawable/button2_selector" 
   android:id="@+id/rb_main_bu2" 
   /> 
  <RadioButton 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:layout_weight="1" 
   android:button="@null" 
   android:background="@drawable/button3_selector" 
   android:id="@+id/rb_main_bu3" 
   /> 
  <RadioButton 
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content" 
   android:layout_weight="1" 
   android:button="@null" 
   android:background="@drawable/button4_selector" 
   android:id="@+id/rb_main_bu4" 
   /> 
 </RadioGroup> 
 
</LinearLayout>

在drawable中创建四个选择器

button_selector.xml

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
 <item android:state_checked="false" android:drawable="@drawable/small_weixin"></item> 
 <item android:state_checked="true" android:drawable="@drawable/small_weixin2"></item> 
</selector>

button2_selector.xml

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
 <item android:state_checked="false" android:drawable="@drawable/small_contact"></item> 
 <item android:state_checked="true" android:drawable="@drawable/small_contact2"></item> 
</selector>

button3_selector.xml

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
 <item android:state_checked="false" android:drawable="@drawable/small_find"></item> 
 <item android:state_checked="true" android:drawable="@drawable/small_find2"></item> 
</selector>

button4_selector.xml

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
 <item android:state_checked="false" android:drawable="@drawable/small_mine"></item> 
 <item android:state_checked="true" android:drawable="@drawable/small_mine2"></item> 
</selector>

四个碎片：

fragment_weixin.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:orientation="vertical" android:layout_width="match_parent" 
 android:layout_height="match_parent"> 
 <ImageView

  android:layout_height="720dp" 
  android:src="@drawable/weixin" 
  /> 
</LinearLayout>

fragment_contact.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:orientation="vertical" android:layout_width="match_parent" 
 android:layout_height="match_parent"> 
 <ImageView 
  android:layout_width="470dp" 
  android:layout_height="720dp" 
  android:src="@drawable/contact" 
  /> 
</LinearLayout>

fragment_find.xml

<?xml version="1.0" encoding="utf-8"?>

 <ImageView 
  android:layout_width="470dp" 
  android:layout_height="720dp" 
  android:src="@drawable/find" 
  /> 
</LinearLayout>

fragment_mine.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:orientation="vertical" android:layout_width="match_parent" 
 android:layout_height="match_parent"> 
 <ImageView 
  android:layout_width="470dp" 
  android:layout_height="720dp" 
  android:src="@drawable/mine" 
  /> 
</LinearLayout>

import android.view.ViewGroup; 
 
/**

 */ 
 
public class WeiXinFragment extends Fragment { 
 @Nullable 
 @Override 
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
  //返回对应的fragment_weixin 
  return inflater.inflate(R.layout.fragment_weixin,null); 
 } 
}

import android.view.View; 
import android.view.ViewGroup; 
 
/**

public class ContactFragment extends Fragment { 
 @Nullable 
 @Override 
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
  //返回对应的fragment_contact 
  return inflater.inflate(R.layout.fragment_contact,null); 
 } 
}

FindFragment

package com.example.g160628_android10_viewpagerfragment_zuoye;

import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
 
/**

 */ 
 
public class FindFragment extends Fragment { 
 @Nullable 
 @Override 
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
  //返回对应的fragment_find 
  return inflater.inflate(R.layout.fragment_find,null); 
 } 
}

MineFragment

package com.example.g160628_android10_viewpagerfragment_zuoye;

public class MineFragment extends Fragment { 
 @Nullable 
 @Override 
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
  //返回对应的fragment_mine 
  return inflater.inflate(R.layout.fragment_mine,null);
