知識(shí)點(diǎn)

1.SelectRecyclerVie：RecycleView封裝類腋腮，多選單選雀彼，同RecyclerView的用法一樣

  • 效果圖


    image.png
第一步：導(dǎo)包：
compile 'cn.yc:YCRecycleViewLib:1.1'
第二步：設(shè)置適配器(注：適配器繼承SelectRecyclerViewAdapter)
 private void initRecycleView() {
        selectView.setLayoutManager(new GridLayoutManager(this, 4));
        adapter = new SelectFollowAdapter(this, lists);
        selectView.setAdapter(adapter);
        //下劃線
        SpaceViewItemLine itemDecoration = new SpaceViewItemLine(SizeUtils.dp2px(5));
        itemDecoration.setPaddingEdgeSide(false);
        itemDecoration.setPaddingStart(false);
        itemDecoration.setPaddingHeaderFooter(false);
        selectView.addItemDecoration(itemDecoration);
    }

2.CommonTabLayout： //導(dǎo)航欄，可用于主頁的底部導(dǎo)航

(用ViewPager和CommonTabLayout實(shí)現(xiàn)底部導(dǎo)航)

  • 使用的額外方法
//        commonTabLayout.showDot(1);//顯示紅點(diǎn)即寡，參數(shù)代表哪個(gè)導(dǎo)航顯示
//        commonTabLayout.showMsg(1,1);//放qq徊哑、微信顯示有幾條未讀信息，第一個(gè)參數(shù)是需要顯示的底部位置聪富，第二個(gè)蠶食是顯示的條數(shù)
//        commonTabLayout.setMsgMargin(1, 2, 2);        //顯示紅點(diǎn)信息位置
//        commonTabLayout.hideMsg(1);//隱藏未讀消息莺丑，參數(shù)代表哪個(gè)導(dǎo)航隱藏
第一步：導(dǎo)包：
compile 'com.flyco.tablayout:FlycoTabLayout_Lib:2.1.0@aar'
第二步：布局引用
 <com.flyco.tablayout.CommonTabLayout
        android:id="@+id/ctl_table"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="#90ffffff"
        tl:tl_iconHeight="23dp"
        tl:tl_iconWidth="23dp"
        tl:tl_indicator_color="#2C97DE"
        tl:tl_indicator_height="0dp"
        tl:tl_textSelectColor="#2C97DE"
        tl:tl_textUnselectColor="#66000000"
        tl:tl_textsize="12sp"
        tl:tl_underline_color="#DDDDDD"
        tl:tl_underline_height="1dp"/>
第三步：在res/values目錄下新加arrays.xml文件，將首頁底部導(dǎo)航的選中與未選擇的圖片和文字以分組的形式寫進(jìn)去
   <!--首頁底部導(dǎo)航欄的標(biāo)題墩蔓，未選中時(shí)-->
    <integer-array name="main_tab_un_select">
        <item name="tab_home">@drawable/tab_home_unselect</item>
        <item name="tab_find">@drawable/tab_speech_unselect</item>
        <item name="tab_data">@drawable/tab_contact_unselect</item>
        <item name="tab_me">@drawable/tab_more_unselect</item>
    </integer-array>

    <!--首頁底部導(dǎo)航欄的標(biāo)題梢莽，選中時(shí)-->
    <integer-array name="main_tab_select">
        <item name="tab_home">@drawable/tab_home_select</item>
        <item name="tab_find">@drawable/tab_speech_select</item>
        <item name="tab_data">@drawable/tab_contact_select</item>
        <item name="tab_me">@drawable/tab_more_select</item>
    </integer-array>

    <!--首頁底部導(dǎo)航欄文字-->
    <string-array name="main_title">
        <item>首頁</item>
        <item>數(shù)據(jù)</item>
        <item>工具</item>
        <item>更多</item>
    </string-array>
第三步：定義實(shí)體類用于存放arrays xml中的資源：

(實(shí)體類實(shí)現(xiàn)CustomTabEntity 接口)

public class TabEntity implements CustomTabEntity {

    public String title;
    public int selectedIcon;
    public int unSelectedIcon;

    public TabEntity(String title, int selectedIcon, int unSelectedIcon) {
        this.title = title;
        this.selectedIcon = selectedIcon;
        this.unSelectedIcon = unSelectedIcon;
    }

    @Override
    public String getTabTitle() {
        return title;
    }

    @Override
    public int getTabSelectedIcon() {
        return selectedIcon;
    }

    @Override
    public int getTabUnselectedIcon() {
        return unSelectedIcon;
    }
}
第四步：獲取arrays xml文件下的資源：
 public ArrayList<CustomTabEntity> getTabEntity() {
        ArrayList<CustomTabEntity> mTabEntities = new ArrayList<>();
        TypedArray mIconUnSelectIds = activity.getResources().obtainTypedArray(R.array.main_tab_un_select);
        TypedArray mIconSelectIds = activity.getResources().obtainTypedArray(R.array.main_tab_select);
        String[] mainTitles = activity.getResources().getStringArray(R.array.main_title);
        for (int i = 0; i < mainTitles.length; i++) {
            int unSelectId = mIconUnSelectIds.getResourceId(i, R.drawable.tab_home_unselect);
            int selectId = mIconSelectIds.getResourceId(i, R.drawable.tab_home_select);
            mTabEntities.add(new TabEntity(mainTitles[i],selectId , unSelectId));
        }
        mIconUnSelectIds.recycle();
        mIconSelectIds.recycle();
        return mTabEntities;
    }
第五步：設(shè)置底部導(dǎo)航以及初始化ViewPager：
  ArrayList<CustomTabEntity> mTabEntities = presenter.getTabEntity();
      (CommonTabLayout)  ctlTable.setTabData(mTabEntities);

   /**
     * 初始化ViewPager數(shù)據(jù)
     */
    private void initViewPager() {
        List<Fragment> fragments = new ArrayList<>();
        HomeFragment homeFragment = new HomeFragment();
        FindFragment findFragment = new FindFragment();
        DataFragment otherFragment = new DataFragment();
        MeFragment meFragment = new MeFragment();
        fragments.add(homeFragment);
        fragments.add(findFragment);
        fragments.add(otherFragment);
        fragments.add(meFragment);

        BasePagerAdapter adapter = new BasePagerAdapter(getSupportFragmentManager(), fragments);
        vpHome.setAdapter(adapter);
        vpHome.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
            }

            @Override
            public void onPageSelected(int position) {
                ctlTable.setCurrentTab(position);
            }

            @Override
            public void onPageScrollStateChanged(int state) {
            }
        });
        vpHome.setOffscreenPageLimit(4);
        vpHome.setCurrentItem(0);
    }


public class BasePagerAdapter extends FragmentPagerAdapter {

    private List<?> mFragment;
    private List<String> mTitleList;

    /**
     * 普通，主頁使用
     */
    public BasePagerAdapter(FragmentManager fm, List<?> mFragment) {
        super(fm);
        this.mFragment = mFragment;
    }

    /**
     * 接收首頁傳遞的標(biāo)題
     */
    public BasePagerAdapter(FragmentManager fm, List<?> mFragment, List<String> mTitleList) {
        super(fm);
        this.mFragment = mFragment;
        this.mTitleList = mTitleList;
    }

    @Override
    public Fragment getItem(int position) {
        return (Fragment) mFragment.get(position);
    }

    @Override
    public int getCount() {
        return mFragment.size();
    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        super.destroyItem(container, position, object);
    }

    /**
     * 首頁顯示title奸披，每日推薦等..
     * 若有問題昏名，移到對應(yīng)單獨(dú)頁面
     */
    @Override
    public CharSequence getPageTitle(int position) {
        if (mTitleList != null) {
            return mTitleList.get(position);
        } else {
            return "";
        }
    }

    public void addFragmentList(List<?> fragment) {
        this.mFragment.clear();
        this.mFragment = null;
        this.mFragment = fragment;
        notifyDataSetChanged();
    }

}

3.滑動(dòng)卡片的效果

  • 效果圖


    image.png
第一步：導(dǎo)包：
   compile 'cn.yc:YCCardViewLib:1.2'
第二步：布局文件
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.ns.yc.yccardviewlib.CardViewLayout
        android:id="@+id/cardview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</FrameLayout>
第三步：實(shí)現(xiàn)效果（pictures是圖片地址集合）
private void initCardVioew(CardViewLayout cardView) {
        cardView.setAdapter(new CardViewLayout.Adapter() {
            @Override
            public int getLayoutId() {
                return R.layout.card_item;
            }

            @Override
            public void bindView(View view, int index) {
                ViewHolder holder = (ViewHolder) view.getTag();
                if (holder == null) {
                    holder = new ViewHolder();
                    holder.imageView = (ImageView) view.findViewById(R.id.image);
                    view.setTag(holder);
                }
                if (pictures.size() > 0) {
                    loadImgByPicassoWithRound(CardViewActivity.this, pictures.get(index), 6, R.mipmap.ic_launcher, holder.imageView);
                }
            }

            @Override
            public int getItemCount() {
                return pictures.size();
            }

            class ViewHolder {
                ImageView imageView;
            }
        });


    }

4.跑馬燈效果（可以自動(dòng)顯示不同的標(biāo)題）

第一步：自定義view
public class MarqueeView extends ViewFlipper {

    private Context mContext;
    private List<? extends CharSequence> notices;
    private boolean isSetAnimDuration = false;
    private OnItemClickListener onItemClickListener;

        super(context, attrs);
        init(context, attrs, 0);
    }

    private void init(Context context, AttributeSet attrs, int defStyleAttr) {
        this.mContext = context;
        if (notices == null) {
            notices = new ArrayList<>();
        }

        TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.MarqueeViewStyle, defStyleAttr, 0);
        interval = typedArray.getInteger(R.styleable.MarqueeViewStyle_mvInterval, interval);
        isSetAnimDuration = typedArray.hasValue(R.styleable.MarqueeViewStyle_mvAnimDuration);
        singleLine = typedArray.getBoolean(R.styleable.MarqueeViewStyle_mvSingleLine, false);

        if (typedArray.hasValue(R.styleable.MarqueeViewStyle_mvTextSize)) {
            textSize = (int) typedArray.getDimension(R.styleable.MarqueeViewStyle_mvTextSize, textSize);
            textSize = px2sp(mContext, textSize);
        }
        textColor = typedArray.getColor(R.styleable.MarqueeViewStyle_mvTextColor, textColor);
        int gravityType = typedArray.getInt(R.styleable.MarqueeViewStyle_mvGravity, TEXT_GRAVITY_LEFT);

                break;
        }
        typedArray.recycle();

        setFlipInterval(interval);
    }

    // 根據(jù)公告字符串啟動(dòng)輪播
    public void startWithText(final String notice) {

    }

}
第二步：布局引用
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

        app:mvTextSize="16sp"
        app:mvSingleLine="true"/>
</LinearLayout>
第三步：設(shè)置適配
    marqueeView.startWithList(list);(list是數(shù)據(jù)集合)
    //設(shè)置點(diǎn)擊事件
    marqueeView.setOnItemClickListener

5.阿里巴巴布局開源庫VLayout(可以仿天貓?zhí)詫毜膹?fù)雜布局)(mvp模式)

image.png

可以參照這個(gè)簡書文章http://www.reibang.com/p/067abf64ed40

第一步：導(dǎo)包
 compile('com.alibaba.android:vlayout:1.2.2@aar') {
        transitive = true
    }
第二步：view層：主要是寫一個(gè)接口，接口中寫需要更新ui的操作的方法
public interface IView {
    //設(shè)置輪播圖
    void setBanner(BannerView bannerView, List<String>pictures);
    //設(shè)置九宮格的點(diǎn)擊
    void setClick(int position);
    //設(shè)置跑馬燈的點(diǎn)擊
    void setMarqueeClick(int position);
    //設(shè)置查看更多的點(diǎn)擊
    void setTitleMoreClick(int position);
}
第三步：preserent層：定義一個(gè)接口样刷，寫需要初始化數(shù)據(jù)的操作方法仑扑；然后寫一個(gè)實(shí)現(xiàn)類實(shí)現(xiàn)這個(gè)接口，重寫相應(yīng)方法置鼻，在具體方法中做相關(guān)請求數(shù)據(jù)的操作镇饮，同時(shí)在preserent的實(shí)現(xiàn)類中需要用構(gòu)造方法將view引用過來，方便數(shù)據(jù)請求完后調(diào)用view接口的方法做更新ui的操作箕母。
  • 接口
public interface IVPresenter {
    DelegateAdapter initRecycler( RecyclerView recyclerView);
    BaseAdapter initBanner();
    BaseAdapter initGvMenu();
    BaseAdapter initMarquee();
