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：
活动的：

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
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
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。。
