新技术VR—应用案例项目分解

首先搭建项目环境

• 1.1.依赖 http库,gson库,RecyclerView+CardView库,design包,Glide库,butterknife库,Adapter-Helper库(BaseQuickAdapter)

• 1.2.还需搭建vr开发环境.

  1.2.1.导入vr开发相关的库 common, commonwidget,通用。全景图片panowidget,全景视频videowidget
  1.2.2.配置应用获取最大内存，防止内存不足选成内存溢出

然后 搭建UI界面

• 2.1.删除ActionBar只在主题风格下面进行NoActionBar配置即可

• 2.2.布局指示器TabLayout 布局ViewPager

• 2.3.查找出来进行初始化

• 2.3.1.创建适配器给ViewPager

配置清单文件 AndroidManifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.itheima.vrproject97">
    
    <uses-permission android:name="android.permission.INTERNET" />

初始化联网配置—VrApp.java

public class VrApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate(); 
        //NoHttp初始化简单配置
        NoHttp.initialize(this);
    }
}

创建自定义控件——StateLayout

展示联网的几种加载状态，所显示的默认图片

//步骤一 。完成构造函数
public class StateLayout extends FrameLayout {
    private View mLoading = null;
    private View mError = null;
    private View mEmpty = null;
    private View mNormal = null;

    public StateLayout(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        //步骤二 将布局打气进来并且作为一个元素添加当前的容器
        View view = View.inflate(context, R.layout.state_layout, null);
        mLoading = view.findViewById(R.id.loading);
        mError = view.findViewById(R.id.error);
        mEmpty = view.findViewById(R.id.nodata);
//      mNormal = view.findViewById(R.id.normal);
        this.addView(view);
    }

    public StateLayout(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public StateLayout(Context context) {
        this(context, null, 0);
    }

    //三。重置让所有的控件变成gone
    private void reset() {
        mLoading.setVisibility(View.GONE);
        mError.setVisibility(View.GONE);
        mEmpty.setVisibility(View.GONE);
        if (mNormal != null) {
            mNormal.setVisibility(View.GONE);
        }

    }

    //显示加载中
    public void showLoading() {
        reset();
        mLoading.setVisibility(View.VISIBLE);
    }

    //显示网络出错
    public void showError() {
        reset();
        mError.setVisibility(View.VISIBLE);
    }

    //显示空
    public void showEmpty() {
        reset();
        mEmpty.setVisibility(View.VISIBLE);
    }

    public void addNormalView(Object normalViewLayout) {
        if (normalViewLayout instanceof Integer) {
            mNormal = LayoutInflater.from(getContext()).inflate((Integer) normalViewLayout, this, false);
        } else {
            mNormal = (View) normalViewLayout;
        }
        this.addView(mNormal);//只有添加到当前布局的元素才可以显示
    }

    //显示正常
    public void showNormal() {
        reset();
        mNormal.setVisibility(View.VISIBLE);
    }

}

布局界面 state_layout.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <ProgressBar
        android:id="@+id/loading"
        style="@android:style/Widget.ProgressBar.Large"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:visibility="gone" />
    
    <TextView
        android:id="@+id/error"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:drawablePadding="10dp"
        android:drawableTop="@drawable/ic_error_page"
        android:gravity="center_horizontal|bottom"
        android:text="加载失败,点击重试"
        android:visibility="gone" />
    
    <ImageView
        android:id="@+id/nodata"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:src="@drawable/ic_empty_page" />

    
    
        
        
        
        
        
        
        
FrameLayout>

工具类的使用

ApiUrls

地址工具类，方便以后更改地址

public class ApiUrls {
    public static final String HOST="http://192.168.191.1:8080";
    public static final String IMAGE_LIST=HOST+"/vr/imagelist";
    public static final String VIDEO_LIST=HOST+"/vr/videolist";
}

HttpUtils

封装联网工具

public class HttpUtils {
    private static RequestQueue queue;
    public static void get(String url, OnResponseListener callBack) {
        //创建请求xml/json
        StringRequest request = (StringRequest) NoHttp.createStringRequest(url, RequestMethod.GET);//1.连接地址 2.请求方法
        //设置缓存模式
        request.setCacheMode(CacheMode.REQUEST_NETWORK_FAILED_READ_CACHE);
        if (queue == null) {
            queue = NoHttp.newRequestQueue();
        }
        // 1.提供多个空的方法 编写业务逻辑
        //2.每个方法都对应一个情况  成功 失败
        queue.add(0, request, callBack);//1.请求what 2.请求 3.回调对象:处理结果的对象。
    }
}

主页面代码

界面布局 activity_main.xml

        MainFragmentAdapter adapter = new MainFragmentAdapter(getSupportFragmentManager());
        viewpager.setAdapter(adapter);
        //2.3.2设置tabLayout外观
        //字体
        tabs.setTabTextColors(Color.parseColor("#707070"),Color.parseColor("#FF9648"));
        //滑块颜色
        tabs.setSelectedTabIndicatorColor(Color.parseColor("#FF9648"));
        //滑块高度
        tabs.setSelectedTabIndicatorHeight(4);

        //2.3.3.把ViewPager设置给TabLayout
        tabs.setupWithViewPager(viewpager);
    }

    private class MainFragmentAdapter extends FragmentPagerAdapter {
        private String[] mTitles = new String[]{"全景图", "全景视频"};
        private Fragment[] mPages = new Fragment[]{new VrPanoFragment(), new VrVideoFragment()};

        public MainFragmentAdapter(FragmentManager fm) {
            super(fm);
        }

        //返回指示需要的标题
        @Override
        public CharSequence getPageTitle(int position) {
            return mTitles[position];
        }

        //返回页面内容
        @Override

            return mPages[position];
        }

        //返回页面数量
        @Override
        public int getCount() {
            return mTitles.length;
        }
    }
}

全景图片的Fragment展示

VrPanoFragment

public class VrPanoFragment extends BaseFragment {

}

抽取Fragment的基类 BaseFragment

BaseFragment

public class BaseFragment extends Fragment {

    private StateLayout stateLayout;
    protected RecyclerView recyclerView;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

        //1.2.创建列表RecyclerView
        recyclerView = new RecyclerView(container.getContext());
        //1.3.显示方式
        recyclerView.setLayoutManager(getLayout(container));
        stateLayout.addNormalView(recyclerView);
        //1.4.显示loading
        stateLayout.showLoading();
        //步骤二。获取服务端数据进行显示
        //2.1.阅读接口文档，测试接口正常 http://192.168.79.34:8080/vr/imagelist
        //2.2.发送请求(nohttp框架初始化)
        getPageData();
        return stateLayout;
    }

    public void getPageData() {
        //2.3.在Callback对应条件的空方法里编写业务逻辑
       final OnResponseListener callBack = new OnResponseListener() {
            @Override
            public void onStart(int what) {
                stateLayout.showLoading();

        VrPanoAdaper adapter=new VrPanoAdaper(R.layout.item_image_card,imageData.list);
        recyclerView.setAdapter(adapter);
    }
}

ImageData 的bean类

public class ImageData {

    public List list;

    public static class ImageItem implements Serializable{
        /**

创建适配器 VrPanoAdaper
继承快速的适配器，在适配器中设置内容，设置点击事件

//3.1.创建适配器类
public class VrPanoAdaper extends BaseQuickAdapter<ImageData.ImageItem> {
    //3.2.指定布局给适配器
    public VrPanoAdaper(int layoutResId, List data) {
        super(layoutResId, data);
    }

    //3.3.赋值
    @Override
    protected void convert(BaseViewHolder helper, final ImageData.ImageItem item) {
        //3.3.1赋值
        helper.setText(R.id.text, item.title);
        //3.3.2.加载图片
        Glide.with(mContext).load(item.url).into((ImageView) helper.getView(R.id.image));
        helper.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(v.getContext(), VrImagePlayActivity.class);
                intent.putExtra("item",item);//要求javaBean实现序列化 implements Serializable
                v.getContext().startActivity(intent);//打开
            }
        });
    }
}

设置条目点击事件转到展示页面—VrImagePlayActivity

        ImageData.ImageItem item= (ImageData.ImageItem) intent.getSerializableExtra("item");
        //步骤一。搭建VR图片开发的环境
        //1.1.导入从github搜索下载的google vr sdk 里面的引用库 common,commonwidget,panowidget(全景图片控件库)
        //1.2.当前这三个库里面缺少序列相关的api,容易引用类找不到，未定义异常
        //1.3.依赖三个库
        //1.4.准备全景图片用来测试代码 放在assets目录下面，例assets/a.jpg
        //1.5.对当前应用进行内存设置，希望应用可使用最大内存 避免OOM  
        //步骤二。加载全景图片到内存中成为Bitmap(bitmap是图片在内存中的表示对象)，展示在全景图片控件
        //2.1.布局全景图片控件
        //2.2.查找控件
        vrPanoramaView = new VrPanoramaView(this);
        setContentView(vrPanoramaView);
        //2.3.因为图片比较大，希望在异步线程里面加载，防止占用主线程
        imageTask = new ImageTask();
        imageTask.execute(item.url);
    }
    private class ImageTask extends AsyncTask<String,Void,Bitmap>
    {
        //2.4.读取资产目录下面的a.jpg图片
        @Override

    //3.4.页面关闭，销毁图片
    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (vrPanoramaView != null) {
            vrPanoramaView.shutdown();
        }
        if (imageTask != null && !imageTask.isCancelled()) {

            imageTask.cancel(true);
            imageTask = null;
        }
    }
}

到这，图片的fragment的页面就已经设置好了
