使用ViewPage+Fragment仿微信界面

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_width="470dp"
  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"?>
<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/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>

Java代码

主Activity：

package com.example.g160628_android10_viewpagerfragment_zuoye; 

import android.content.res.Resources;
import android.support.annotation.IdRes;
import android.support.v4.app.Fragment;
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 android.os.Bundle;
import android.view.View;
import android.widget.RadioButton;
import android.widget.RadioGroup; 

import java.util.ArrayList;
import java.util.List; 

public class MainActivity extends AppCompatActivity {
 private List<Fragment> fragments=new ArrayList<>();
 private ViewPager vp_main_view;
 private RadioGroup rg_main_group;
 private List<View> views; 

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  //把碎片加入到碎片集合中
  fragments.add(new WeiXinFragment());
  fragments.add(new ContactFragment());
  fragments.add(new FindFragment());
  fragments.add(new MineFragment()); 

  //找到自己的ViewPager
  vp_main_view = (ViewPager) findViewById(R.id.vp_main_view);
  vp_main_view.setAdapter(new MyAdapter(getSupportFragmentManager()));
  //设置当前的碎片为1
  vp_main_view.setCurrentItem(1); 

  //获得单选按钮组
  rg_main_group = (RadioGroup) findViewById(R.id.rg_main_group);
  //设置单选按钮组的选择事件
  rg_main_group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
   @Override
   public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
    Resources res=MainActivity.this.getResources();
    switch (checkedId) {
     case R.id.rb_main_bu1:
      vp_main_view.setCurrentItem(0);
      break;
     case R.id.rb_main_bu2:
      vp_main_view.setCurrentItem(1);
      break;
     case R.id.rb_main_bu3:

      break;
    }
   }
  }); 

  //获得所有的单选框
  views=rg_main_group.getTouchables(); 

  //设置单选框事件
  vp_main_view.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
   @Override
   public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { 

   } 

   @Override
   public void onPageSelected(int position) {
    //设置选中
    RadioButton button= (RadioButton) views.get(position);
    button.setChecked(true);
   } 

   @Override
   public void onPageScrollStateChanged(int state) { 

   }
  }); 

 } 

 //定义属于自己的适配器
 class MyAdapter extends FragmentPagerAdapter{ 

  public MyAdapter(FragmentManager fm) {
   super(fm);
  } 

  //获得碎片的所有
  @Override
  public Fragment getItem(int position) {
   return fragments.get(position);
  } 

  //返回碎片的长度
  @Override
  public int getCount() {
   return fragments.size();
  }
 } 

}

四个碎片对应的Fragment

import android.view.LayoutInflater;
import android.view.View;
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.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; 

/**

 */ 

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; 

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; 

/**

 */ 

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);
 }
}

需要的图片
