<selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_checked="true" android:drawable="@color/colorAccent"></item> <item android:drawable="@color/colorPrimary"></item></selector>功能代码:
TabLayout的功能代码
public class MainActivity extends AppCompatActivity { private DrawerLayout drawerLayout; private ListView listView; private RelativeLayout rel; private ArrayList datas; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //查找组件 drawerLayout = (DrawerLayout) findViewById(R.id.drlayout); listView = (ListView) findViewById(R.id.lv); rel = (RelativeLayout) findViewById(R.id.rel); //构造数据 datas = new ArrayList<String>(); datas.add("个人设置"); datas.add("缓存"); datas.add("夜间模式"); datas.add("配置"); //主页面Fragment ContentFragment contentFragment=new ContentFragment(); getSupportFragmentManager().beginTransaction().replace(R.id.fcontent,contentFragment).commit(); //设置数组适配器 ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, datas); listView.setAdapter(adapter); listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { //关闭侧滑菜单 drawerLayout.closeDrawer(rel); } });}}自定义Gridview的方法
public class MyGridview extends GridView { public MyGridview(Context context) { super(context); } public MyGridview(Context context, AttributeSet attrs) { super(context, attrs); } public MyGridview(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec = MeasureSpec.makeMeasureSpec( Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); }}Banner需要的imagload的方法
public class Imagload extends ImageLoader { @Override public void displayImage(Context context, Object path, ImageView imageView) { //得到ImageLoader的实例 com.nostra13.universalimageloader.core.ImageLoader instance = com.nostra13.universalimageloader.core.ImageLoader.getInstance(); //通过ImageLoader设置图片 instance.displayImage((String) path, imageView); }}实现三秒切换图片的方法
public class Confregment2 extends Fragment{ private int count = 0; private ImageView img; ArrayList<String> list = new ArrayList<>(); private Handler handler=new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); count++; String s = list.get(count % list.size()); ImageLoader.getInstance().displayImage(s,img, MyApp.getDefaultDisplayOption()); sendEmptyMessageDelayed(0,3000); } }; @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = View.inflate(getActivity(), R.layout.confragment2, null); img = (ImageView) view.findViewById(R.id.img); return view; } @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); MyTask myTask = new MyTask(new MyTask.Icallbacks() { @Override public void updateUiByjson(String jsonstr) { Gson gson = new Gson(); Bean2 bean = gson.fromJson(jsonstr, Bean2.class); List<Bean2.DataScrollBean> dataScroll = bean.getDataScroll(); Log.i("aaa",dataScroll.toString()); for(int i=0;i<dataScroll.size();i++) { String imageurl = dataScroll.get(i).getIMAGEURL(); String url="http://www.93.gov.cn"+imageurl; list.add(url); } handler.sendEmptyMessage(0); } }); myTask.execute("http://www.93.gov.cn/93app/data.do?channelId=0&startNum=0"); }}实现viewpage+fragment+RadioGroup联动的代码
public class ContentFragment extends Fragment { private RadioGroup rg; private ViewPager vp; List<Fragment> list = new ArrayList<>(); @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View v=View.inflate(getActivity(), R.layout.item,null); rg = (RadioGroup) v.findViewById(R.id.rg); vp = (ViewPager) v.findViewById(R.id.vp); return v; } @RequiresApi(api = Build.VERSION_CODES.M) @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); list.add(new shouyefregment()); list.add(new flfregment()); list.add(new fxfregment()); list.add(new cwcfregment()); list.add(new wodefregment()); vp.setOffscreenPageLimit(list.size()); myadapter myadapter = new myadapter(getChildFragmentManager()); vp.setAdapter(myadapter); vp.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } @Override public void onPageSelected(int position) { rg.check(rg.getChildAt(position).getId()); } @Override public void onPageScrollStateChanged(int state) { } }); rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) { switch (checkedId){ case R.id.rb_01: vp.setCurrentItem(0); break; case R.id.rb_02: vp.setCurrentItem(1); break; case R.id.rb_03: vp.setCurrentItem(2); break; case R.id.rb_04: vp.setCurrentItem(3); break; case R.id.rb_05: vp.setCurrentItem(4); break; } } }); } class myadapter extends FragmentPagerAdapter { public myadapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { return list.get(position); } @Override public int getCount() { return list.size(); } }}实现Tablayout+viewpage+fragment的代码
public class flfregment extends Fragment{ private VerticalTabLayout tab; ArrayList<String> datas = new ArrayList<>(); private ViewPager vp; @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = View.inflate(getActivity(), R.layout.flfragment, null); tab = (VerticalTabLayout) view.findViewById(R.id.tab); vp = (ViewPager) view.findViewById(R.id.vp); return view; } @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); //添加选项卡 datas.add("香包手袋"); datas.add("美妆个护"); datas.add("钟表珠宝"); datas.add("手机数码"); datas.add("电脑办公"); datas.add("家用电器"); datas.add("食品生鲜"); datas.add("酒水饮料"); datas.add("母婴童装"); //设置加载页数 vp.setOffscreenPageLimit(datas.size()); vp.setAdapter(new MyAdapter(getChildFragmentManager())); //进行关联 tab.setupWithViewPager(vp); } class MyAdapter extends FragmentPagerAdapter{ //带参的构造方法 public MyAdapter(FragmentManager fm) { super(fm); } //返回选项卡的文本 ，，，添加选项卡 @Override public CharSequence getPageTitle(int position) { return datas.get(position); } @Override public Fragment getItem(int position) { Log.d("zzz","position:"+position); //创建fragment对象并返回 Confregment2 confregment2 = new Confregment2(); return confregment2; } @Override public int getCount() { return datas.size();//返回选项卡的数量 } }}PullToRefreshScrollView嵌套Banner.GridView实现功能代码
public class shouyefregment extends Fragment { private GridView gv; private int index = 400; private ListView pullToRefreshListView; private Handler myHandler = new Handler(); List<Bean.NewslistBean> data=new ArrayList<Bean.NewslistBean>(); private ViewPager vp; List<String> list = new ArrayList<>(); private Banner banner; private PullToRefreshScrollView sv; private MyAdapter adapter; //https://api.tianapi.com/wxnew/?key=8d6e3228d25298f13af4fc40ce6c9679&num=10&page=3 @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = View.inflate(getActivity(), R.layout.syfragment, null);
