首先设置布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
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.example.administrator.myradiobutton.MainActivity">
<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>
<RadioGroup
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<RadioButton
android:id="@+id/xinwen"
android:text="新闻"
android:drawableTop="@drawable/select_main_xinwen"
android:checked="true"
style="@style/ab_style" />
<RadioButton
android:id="@+id/pinglun"
android:text="评论"
android:drawableTop="@drawable/select_main_pinlun"
android:checked="true"
style="@style/ab_style" />
<RadioButton
android:id="@+id/yonghu"
android:text="用户"
android:drawableTop="@drawable/select_main_yonghu"
android:checked="true"
style="@style/ab_style" />
<RadioButton
android:id="@+id/shezhi"
android:text="设置"
android:drawableTop="@drawable/select_main_setting"
android:checked="true"
style="@style/ab_style" />
</RadioGroup>
</LinearLayout>
其中style样式设置：右键生成公共样式
然后设置每个Fragment页面
然后设置adapter适配器：
package com.gfd.tab;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import com.gfd.tab.ui.fragment.HomeFragment;
import com.gfd.tab.ui.fragment.LoveFragment;
import com.gfd.tab.ui.fragment.RenFragment;
import com.gfd.tab.ui.fragment.VedioFragment;
/*
* PagerAdapter
*
* FragmentPagerAdapter
*
* FragmentStatePagerAdapter
*
*
*
*/
public class HomePagerAdapter extends FragmentPagerAdapter {
public HomePagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new LoveFragment();
break;
case 2:
fragment = new RenFragment();
break;
case 3:
fragment = new VedioFragment();
break;
}
return fragment;
}
@Override
public int getCount() {
return 4;
}
/* @Override
public int getCount() {
return 5;
}
*//**
* 作用：是否创建一个新页面 ： true:不创建 false :创建
* @param view : 当前页面展示的视图
* @param object ：将要滑进来的视图
* *//*
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
Log.e("tag","instantiateItem -----" + position);
TextView view = new TextView(container.getContext());
view.setText("fffffffffff");
container.addView(view);
return view;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
Log.e("tag","destroyItem -----" + position);
}*/
}
最后activity设置
package com.gfd.tab.ui.activity;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import com.gfd.tab.HomePagerAdapter;
import com.gfd.tab.R;
import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;
public class MainActivity extends AppCompatActivity {
@BindView(R.id.vp_home)
ViewPager vpHome;
@BindView(R.id.rb_mian_home)
RadioButton rbMianHome;
@BindView(R.id.rb_mian_love)
RadioButton rbMianLove;
@BindView(R.id.rb_mian_ren)
RadioButton rbMianRen;
@BindView(R.id.rb_mian_vedio)
RadioButton rbMianVedio;
@BindView(R.id.radiogroup)
RadioGroup radioGroup;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
vpHome.setAdapter(new HomePagerAdapter(getSupportFragmentManager()));
vpHome.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
RadioButton radioButton = (RadioButton) radioGroup.getChildAt(position);
radioButton.setChecked(true);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
@OnClick({R.id.rb_mian_home, R.id.rb_mian_love, R.id.rb_mian_ren, R.id.rb_mian_vedio})
public void onClick(View view) {
switch (view.getId()) {
case R.id.rb_mian_home://首页
vpHome.setCurrentItem(0,false);
break;
case R.id.rb_mian_love://关注
vpHome.setCurrentItem(1,false);
break;
case R.id.rb_mian_ren://联系人
vpHome.setCurrentItem(2,false);
break;
case R.id.rb_mian_vedio://视频
vpHome.setCurrentItem(3,false);
break;
}
}
}
--------------------
以上列子与之前的不同，代码少了哈哈，之前将Fragment放入了集合中使用，具体详看另个文件！！！
2.静态页面，点击改变上面页面不滑动代码：
需改变，布局：
activity：
使用事务完成：
package com.gfd.tab.ui.activity;
import android.os.Bundle;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.FrameLayout;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import com.gfd.tab.R;
import com.gfd.tab.ui.fragment.HomeFragment;
import com.gfd.tab.ui.fragment.LoveFragment;
import com.gfd.tab.ui.fragment.RenFragment;
import com.gfd.tab.ui.fragment.VedioFragment;
import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.OnClick;
public class SecondActivity extends AppCompatActivity {
@BindView(R.id.frame_layout)
FrameLayout layout;
@BindView(R.id.rb_mian_home)
RadioButton rbMianHome;
@BindView(R.id.rb_mian_love)
RadioButton rbMianLove;
@BindView(R.id.rb_mian_ren)
RadioButton rbMianRen;
@BindView(R.id.rb_mian_vedio)
RadioButton rbMianVedio;
@BindView(R.id.radiogroup)
RadioGroup radioGroup;
private FragmentManager fragmentManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_second);
ButterKnife.bind(this);
fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.frame_layout,new HomeFragment()).commit();
}
@OnClick({R.id.rb_mian_home, R.id.rb_mian_love, R.id.rb_mian_ren, R.id.rb_mian_vedio})
public void onClick(View view) {
switch (view.getId()) {
case R.id.rb_mian_home://首页
fragmentManager.beginTransaction().replace(R.id.frame_layout,new HomeFragment()).commit();
break;
case R.id.rb_mian_love://关注
fragmentManager.beginTransaction().replace(R.id.frame_layout,new LoveFragment()).commit();
break;
case R.id.rb_mian_ren://联系人
fragmentManager.beginTransaction().replace(R.id.frame_layout,new RenFragment()).commit();
break;
case R.id.rb_mian_vedio://视频
fragmentManager.beginTransaction().replace(R.id.frame_layout,new VedioFragment()).commit();
break;
}
}
}
-------------除去adapter，-----
