守望先锋app

上次的功能完成了英雄名字、id、头像的下载并使用RecyclerView展示，

所以接下来就是点击每个英雄的caraview就能打开下一个活动进行英雄的介绍。先打开暴雪的官网查看有那些技能、故事、图片可供下载。首先是http://ow.blizzard.cn/heroes/

如果我想要看源氏的详细介绍，点击之后就打开了http://ow.blizzard.cn/heroes/genji，可以发现比上一个网站多了一个genji，genji就是源氏英文名也是上次获得的id。

详细介绍中有：

概况：角色类型 技能 攻击简介

故事：英雄简介，台词，背景故事

然后是html代码的分析了，大概想要的内容可分为三个部分：

1、英雄图片

这个src="http://overwatch.nos.netease.com/1/assets/images/hero/genji/full-portrait.png"可以得到英雄的全身照片.png

2、技能、角色类型

 

 

 3、故事

所以相应的代码就是：

    Elements elements1 = doc.select(".hero-image"); //读取图片url
    Elements elements2 = doc.select(".h2,.hero-detail-role-name"); //角色类型
    Elements elements3 = doc.select(".hero-ability"); //读取技能
    Elements elements4 = doc.select(".h5");//读取技能名字
    Elements elements5 = doc.select(".hero-ability-descriptor");//读取技能描述
    Elements elements6 = doc.select(".hero-detail-description");//读取英雄描述
    Elements elements7 = doc.select(".hero-bio-copy");//读取英雄简介
    Elements elements8 = doc.select(".h4,.hero-detail-title");//读取英雄台词
    Elements elements9 = doc.select(".hero-bio-backstory");//读取英雄故事

大概分析就结束了，然后就是活动布局的设定了，

这部分的布局首先是一个可折叠的标题栏用于展示英雄图片，然后是一个可滑动切换的标签栏用于概况和故事的切换。

然后viewpager中将是两个Fragment分别展示概况和故事。

xml代码分别是：

然后就是java代码的编写了，首先要解决布局中一个很严重的问题viewpager和NestedScrollView是有冲突的，所以新建了一个WrapContentHeightViewPager类继承自ViewPager重写了onMeasure方法（这段是网上人家的代码，但是现在我找不到来源了==），

public class WrapContentHeightViewPager extends ViewPager {
    public WrapContentHeightViewPager(Context context) {
        super(context);
    }

    public WrapContentHeightViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        int height = 0;
        for (int i = 0; i < getChildCount(); i++) {
            View child = getChildAt(i);
            child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
            int h = child.getMeasuredHeight();
            if (h > height) height = h;
        }
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

活动的java代码：

public class HeroDetails extends AppCompatActivity {

    public static final String Hero_NAME = "hero_name";

    public static final String Hero_ID = "hero_id";

    private Handler handler;

    String imgUrl;

    private List<HeroSkill> heroSkillList = new ArrayList<>();

    private List<String> list_title;
    private List<Fragment> list_fragment;



    private FragmentAdapter fAdapter;

    private SkillFragment nFragment;
    private Fragment2 sFragment;

    private TabLayout tab_title;
    private ViewPager vp_pager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hero_details);

        Intent intent = getIntent();
        final String heroName =intent.getStringExtra(Hero_NAME);
        String heroId =intent.getStringExtra(Hero_ID);
        String url = "http://ow.blizzard.cn/heroes/" + heroId;

        //标题栏设定
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        //设置标题栏标题
        CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collaping_toobar);
        collapsingToolbar.setTitle(heroName);
        collapsingToolbar.setExpandedTitleColor(Color.parseColor("#00C3FF") );
        collapsingToolbar.setCollapsedTitleTextColor(Color.parseColor("#00C3FF") );

        //让返回图标显示出来
        ActionBar actionBar = getSupportActionBar();
        if(actionBar != null){
            actionBar.setDisplayHomeAsUpEnabled(true);
        }

        initHeroes(url);
        handler = new Handler(){
            @Override
            public void handleMessage(Message msg) {
                if(msg.what == 1){
                    ImageView overWatchImageView = (ImageView) findViewById(R.id.hero_image_view);
                    Glide.with(HeroDetails.this).load(imgUrl).into(overWatchImageView);
                    tab_title = (TabLayout)findViewById(R.id.tablayout);
                    vp_pager = (ViewPager)findViewById(R.id.viewpager);
                    fragmentChange();
                }
            }
        };
    }

    //读取数据
    private void initHeroes(String Url){
        HttpUtil.sendOkHttpRequest(Url, new Callback() {
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                final String responseText = response.body().string();
                new Thread(new Runnable() {
                    @Override
                    public void run() {
                        Document doc = Jsoup.parse(responseText);//将String类型的html转换为Document
                        Elements elements1 = doc.select(".hero-image"); //读取图片url
                        Elements elements2 = doc.select(".h2,.hero-detail-role-name"); //角色类型
                        Elements elements3 = doc.select(".hero-ability"); //读取技能
                        Elements elements4 = doc.select(".h5");//读取技能名字

                        Log.d("message", elements9.text());
                        List<String> heroBio = new ArrayList<String>();

                        for(int i= 0; i < elements7.size(); i++) {
                            heroBio.add(elements7.get(i).text());
                        }
                        heroBio.add(elements8.get(6).text());
                        heroBio.add(elements9.text());

                        imgUrl = elements1.attr("src");

                        for(int j = 0; j < elements4.size(); j++ ) {
                            String skillImgUrl = elements3.select("img").get(j).attr("src");
                            String skillName = elements4.get(j).text();
                            String skillDescriptor = elements5.get(j).select("p").text();
                            HeroSkill heroSkill = new HeroSkill(skillImgUrl,skillName,skillDescriptor,elements2.text(),elements6.text(),heroBio);
                            heroSkillList.add(heroSkill);
                        }
                        Message msg = new Message();
                        msg.what = 1;
                        handler.sendMessage(msg);
                    }
                }).start();
            }

            @Override
            public void onFailure(Call call, IOException e) {
                e.printStackTrace();
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        Toast.makeText(HeroDetails.this, "数据获取失败", Toast.LENGTH_SHORT).show();
                    }
                });
            }
        });
    }

    //点击左上角的返回后退出活动
    public boolean onOptionsItemSelected(MenuItem item){
        switch (item.getItemId()){
            case android.R.id.home:
                finish();
                return true;
        }
        return super.onOptionsItemSelected(item);
    }

    //用于和Fragment的通信
    public List<HeroSkill> getHeroSkillList(){
        return heroSkillList;
    }

    private void fragmentChange()
    {
        list_fragment = new ArrayList<>();

        nFragment = new SkillFragment();
        sFragment = new Fragment2();


        list_fragment.add(nFragment);
        list_fragment.add(sFragment);

        list_title = new ArrayList<>();
        list_title.add("技能");
        list_title.add("概况");

        fAdapter = new FragmentAdapter(getSupportFragmentManager(),list_fragment,list_title);
        vp_pager.setAdapter(fAdapter);

        //将tabLayout与viewpager连起来
        tab_title.setupWithViewPager(vp_pager);
    }
}

这里新建的HeroSkill类：

public class HeroSkill {

    private String skillImg;

    private String skillName;

    private String skillDescriptor;

    private String heroStyle;

    private String heroSmileDescriptor;

    private List<String> heroBio;

    public HeroSkill(String skillImg, String skillName,String skillDescriptor,String heroStyle, String heroSmileDescriptor,List<String> heroBio ) {
        this.skillDescriptor = skillDescriptor;
        this.skillImg = skillImg;
        this.skillName = skillName;
        this.heroStyle = heroStyle;
        this.heroSmileDescriptor = heroSmileDescriptor;
        this.heroBio = heroBio;

    }

    public String getSkillImg() {
        return skillImg;
    }

    public void setSkillImg(String skillImg) {
        this.skillImg = skillImg;
    }

    public String getSkillName() {
        return skillName;
    }

    public void setSkillName(String skillName) {
        this.skillName = skillName;
    }

    public String getSkillDescriptor() {
        return skillDescriptor;
    }

    public void setSkillDescriptor(String skillDescriptor) {
        this.skillDescriptor = skillDescriptor;
    }

    public String getHeroStyle() {
        return heroStyle;
    }

    public void setHeroStyle(String heroStyle) {
        this.heroStyle = heroStyle;
    }

    public String getHeroSmileDescriptor() {
        return heroSmileDescriptor;
    }

    public void setHeroSmileDescriptor(String heroSmileDescriptor) {
        this.heroSmileDescriptor = heroSmileDescriptor;
    }

    public List<String> getHeroBio() {
        return heroBio;
    }

    public void setHeroBio(List<String> heroBio) {
        this.heroBio = heroBio;
    }
}

然后还有两个fragment的代码，还有连接fragment TabLayout ViewPager的FragmentAdapter继自FragmentPagerAdapter。就不贴了。。
