這期內(nèi)容當中小編將會給大家?guī)碛嘘P(guān)怎么在ViewPage中使用Fragment模擬一個微信界面,文章內(nèi)容豐富且以專業(yè)的角度為大家分析和敘述,閱讀完這篇文章希望大家可以有所收獲。
界面與碎片:
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"> <!--設(shè)置ViewPager與單選組--> <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中創(chuàng)建四個選擇器
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>
四個碎片:
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代碼
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())); //設(shè)置當前的碎片為1 vp_main_view.setCurrentItem(1); //獲得單選按鈕組 rg_main_group = (RadioGroup) findViewById(R.id.rg_main_group); //設(shè)置單選按鈕組的選擇事件 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: vp_main_view.setCurrentItem(2); break; case R.id.rb_main_bu4: vp_main_view.setCurrentItem(3); break; } } }); //獲得所有的單選框 views=rg_main_group.getTouchables(); //設(shè)置單選框事件 vp_main_view.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } @Override public void onPageSelected(int position) { //設(shè)置選中 RadioButton button= (RadioButton) views.get(position); button.setChecked(true); } @Override public void onPageScrollStateChanged(int state) { } }); } //定義屬于自己的適配器 class MyAdapter extends FragmentPagerAdapter{ public MyAdapter(FragmentManager fm) { super(fm); } //獲得碎片的所有 @Override public Fragment getItem(int position) { return fragments.get(position); } //返回碎片的長度 @Override public int getCount() { return fragments.size(); } } }
四個碎片對應(yīng)的Fragment
WeiXinFragment
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; /** * Created by Administrator on 2017/6/15. */ public class WeiXinFragment extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { //返回對應(yīng)的fragment_weixin return inflater.inflate(R.layout.fragment_weixin,null); } }
ContactFragment
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; /** * Created by Administrator on 2017/6/15. */ public class ContactFragment extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { //返回對應(yīng)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; /** * Created by Administrator on 2017/6/15. */ public class FindFragment extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { //返回對應(yīng)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; /** * Created by Administrator on 2017/6/15. */ public class MineFragment extends Fragment { @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { //返回對應(yīng)的fragment_mine return inflater.inflate(R.layout.fragment_mine,null); } }
