引导页的页面
首先是布局文件

  <android.support.v4.view.ViewPagerandroid:id="@+id/pager"android:layout_width="match_parent"android:layout_height="match_parent" /><RadioGroupandroid:id="@+id/group"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"android:layout_marginTop="-80dp"android:gravity="center"></RadioGroup><Buttonandroid:id="@+id/btn"android:layout_marginTop="-50dp"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="点击跳转"/>

引导页主页面

 protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);int[] arr = {R.drawable.aa,R.drawable.bb,R.drawable.cc,R.drawable.dd};pager = (ViewPager)findViewById(R.id.pager);btn =(Button) findViewById(R.id.btn);group = (RadioGroup)findViewById(R.id.group);btn.setVisibility(View.GONE);btn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent(MainActivity.this, ShouActivity.class);startActivity(intent);}});list = new ArrayList<>();for (int i = 0 ;i<arr.length;i++){ImageView imageView = new ImageView(MainActivity.this);imageView.setImageResource(arr[i]);list.add(imageView);RadioButton button = new RadioButton(MainActivity.this);group.addView(button);}group.check(group.getChildAt(0).getId());Log.e("yxx","打印数据"+list.size());pager.setAdapter(new PagerAdapter() {@Overridepublic int getCount() {return list.size();}@Overridepublic boolean isViewFromObject(@NonNull View arg0, @NonNull Object agr1) {return arg0 == agr1;}@NonNull@Overridepublic Object instantiateItem(@NonNull ViewGroup container, int position) {ImageView view = list.get(position);container.addView(view);return view;}@Overridepublic void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {container.removeView((View) object);}});pager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {@Overridepublic void onPageScrolled(int i, float v, int i1) {}@Overridepublic void onPageSelected(int i) {group.check(group.getChildAt(i).getId());if(i == list.size()-1){btn.setVisibility(View.VISIBLE);}else{btn.setVisibility(View.GONE);}}@Overridepublic void onPageScrollStateChanged(int i) {}});}

这时候就会进入到我们的切换页面和抽屉
这个时候防止页面混乱所以写了两个LinearLayout

 <android.support.v4.widget.DrawerLayout 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"tools:context=".MyActivity.ShouActivity"android:orientation="vertical"android:id="@+id/drawlay"><LinearLayoutandroid:layout_width="150dp"android:layout_height="match_parent"android:layout_gravity="left"android:orientation="vertical"android:background="@color/colorPrimaryDark"><TextViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:text="我是神"/><TextViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:text="我是神"/><TextViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:text="我是神"/></LinearLayout><LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><FrameLayoutandroid:id="@+id/frag"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="9"></FrameLayout><RadioGroupandroid:id="@+id/group"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"android:orientation="horizontal"><RadioButtonandroid:id="@+id/radio0"android:layout_width="0dp"android:layout_height="match_parent"android:button="@null"android:layout_weight="1"android:gravity="center"android:text="首页"/><RadioButtonandroid:id="@+id/radio1"android:layout_width="0dp"android:layout_height="match_parent"android:button="@null"android:layout_weight="1"android:gravity="center"android:text="我的"/><RadioButtonandroid:id="@+id/radio2"android:layout_width="0dp"android:layout_height="match_parent"android:button="@null"android:layout_weight="1"android:gravity="center"android:text="第三个"/></RadioGroup></LinearLayout></android.support.v4.widget.DrawerLayout>

接下来看主要的代码

protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_shou);drawr = (DrawerLayout)findViewById(R.id.drawlay);frag = (FrameLayout)findViewById(R.id.frag);group = (RadioGroup)findViewById(R.id.group);actionBar = getSupportActionBar();actionBar.setDisplayHomeAsUpEnabled(true);drawr.addDrawerListener(new DrawerLayout.DrawerListener() {@Overridepublic void onDrawerSlide(@NonNull View view, float v) {}@Overridepublic void onDrawerOpened(@NonNull View view) {}@Overridepublic void onDrawerClosed(@NonNull View view) {Toast.makeText(ShouActivity.this,"我关闭了",Toast.LENGTH_LONG).show();}@Overridepublic void onDrawerStateChanged(int i) {}});ArrayList<Fragment> list = new ArrayList<>();manager = getSupportFragmentManager();FragmentTransaction transaction = manager.beginTransaction();fragment1 = new Fragment1();fragment2 = new Fragment2();fragment3 = new Fragment3();transaction.add(R.id.frag, fragment1,"fragment1");transaction.add(R.id.frag, fragment2);transaction.add(R.id.frag, fragment3);transaction.show(fragment1).hide(fragment2).hide(fragment3);transaction.commit();group.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {@Overridepublic void onCheckedChanged(RadioGroup group, int checkedId) {FragmentTransaction transaction1 = manager.beginTransaction();switch (checkedId){case R.id.radio0:transaction1.show(fragment1).hide(fragment2).hide(fragment3).commit();break;case R.id.radio1:transaction1.show(fragment2).hide(fragment1).hide(fragment3).commit();break;case R.id.radio2:transaction1.show(fragment3).hide(fragment2).hide(fragment1).commit();break;}}});}//因为是Fragment之间的传值所以在Activity之间进行传值@Overrideprotected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {super.onActivityResult(requestCode, resultCode, data);Fragment fragment1 = manager.findFragmentByTag("fragment1");fragment1.onActivityResult(requestCode, resultCode, data);}

接下来就到我们的频道了

<LinearLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"><android.support.design.widget.TabLayoutandroid:id="@+id/tablayout"android:layout_width="0dp"android:layout_height="wrap_content"android:layout_weight="1"/><Buttonandroid:id="@+id/btn"android:layout_width="wrap_content"android:layout_height="wrap_content"android:text="+"/></LinearLayout><android.support.v4.view.ViewPagerandroid:id="@+id/pager1"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"/></LinearLayout>

这个是具体代码

 public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {View view = inflater.inflate(R.layout.fragment1,container,false);tablayout = (TabLayout)view.findViewById(R.id.tablayout);pager = (ViewPager)view.findViewById(R.id.pager1);btn =(Button)view.findViewById(R.id.btn);myAdapter = new MyAdapter(getChildFragmentManager());pager.setAdapter(myAdapter);tablayout.setupWithViewPager(pager);btn.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {ChannelActivity.startChannelActivity((AppCompatActivity) getActivity(),channellist);}});initData();return view;}private void initData() {channellist.add(new ChannelBean("北京",true));channellist.add(new ChannelBean("北京1",true));channellist.add(new ChannelBean("北京2",true));channellist.add(new ChannelBean("北京3",false));channellist.add(new ChannelBean("北京4",false));for (int i = 0 ;i<channellist.size();i++){if(channellist.get(i).isSelect()){tablayout.addTab(tablayout.newTab().setText(channellist.get(i).getName()));if(i==0){fragmentlist.add(new Fragment01());}else if(i == 1){fragmentlist.add(new Fragment02());}else{fragmentlist.add(new Fragment03());}}}myAdapter.notifyDataSetChanged();}@Overridepublic void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {super.onActivityResult(requestCode, resultCode, data);String extra = data.getStringExtra(ChannelActivity.RESULT_JSON_KEY);Gson gson = new Gson();Type type = new TypeToken<ArrayList<ChannelBean>>() {}.getType();channellist  = gson.fromJson(extra, type);tablayout.removeAllTabs();fragmentlist.clear();for (int i = 0 ;i<channellist.size();i++){if(channellist.get(i).isSelect()){tablayout.addTab(tablayout.newTab().setText(channellist.get(i).getName()));if(i==0){fragmentlist.add(new Fragment01());}else if(i == 1){fragmentlist.add(new Fragment02());}else{fragmentlist.add(new Fragment03());}}}myAdapter.notifyDataSetChanged();}private class MyAdapter extends FragmentPagerAdapter {public MyAdapter(FragmentManager fm) {super(fm);}@Overridepublic Fragment getItem(int i) {return fragmentlist.get(i);}@Overridepublic int getCount() {return fragmentlist.size();}@Nullable@Overridepublic CharSequence getPageTitle(int position) {return channellist.get(position).getName();}}

轮播图和上下拉刷新

布局
导入依赖

  <com.youth.banner.Bannerandroid:id="@+id/bander"android:layout_weight="3"android:layout_width="match_parent"android:layout_height="0dp"/><com.handmark.pulltorefresh.library.PullToRefreshListViewandroid:id="@+id/pth"android:layout_weight="7"android:layout_width="match_parent"android:layout_height="0dp"/>

判断网咯

public class Netutil {public static boolean isconn(Context context) {boolean isf = false;ConnectivityManager systemService = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);NetworkInfo networkInfo = systemService.getActiveNetworkInfo();if(networkInfo!=null){isf = true;}return isf;}
}

图片网络获取

public class MApp extends Application {@Overridepublic void onCreate() {super.onCreate();ImageLoaderConfiguration build = new ImageLoaderConfiguration.Builder(this).build();ImageLoader instance = ImageLoader.getInstance();instance.init(build);/* ImageLoaderConfiguration configuration = new ImageLoaderConfiguration.Builder(this).build();ImageLoader.getInstance().init(configuration);*/}
}
