VR的简单shi'yong

        1.androidmainifest文件中配置

android:largeHeap="true"

2.model配置  compile 'com.google.protobuf.nano:protobuf-javanano:3.0.0-alpha-7'

3.xml  

<com.google.vr.sdk.widgets.pano.VrPanoramaView
    android:id="@+id/vr"
    android:layout_width="match_parent"
    android:layout_height="match_parent">com.google.vr.sdk.widgets.pano.VrPanoramaView>

导入model   common  commonwidget   panowidget

4.//初始化vr

    //设置左下角信息按钮隐藏

     vr.setInfoButtonEnabled(false);

    //隐藏右下角全屏显示按钮

vr.setFullscreenButtonEnabled(false);

//切换VR的模式   参数: VrWidgetView.DisplayMode.FULLSCREEN_STEREO设备模式(手机横着放试试)  VrWidgetView.DisplayMode.FULLSCREEN_MONO手机模式
vr.setDisplayMode(VrPanoramaView.DisplayMode.FULLSCREEN_STEREO);
 //D.设置对VR运行状态的监听,如果VR运行出现错误,可以及时处了.

vr.setEventListener(new MyListner());

//设置立体显示
voidVoidBitmapAsyncTask = new AsyncTask<Void, Void, Bitmap>() {

    @Override
    protected Bitmap doInBackground(Void... voids) {
        try {
            InputStream open= getAssets().open("andes.jpg");
            Bitmap bitmap= BitmapFactory.decodeStream(open);
            return bitmap;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Bitmap bitmap) {
        VrPanoramaView.Options options= new VrPanoramaView.Options();
        //设置立体显示
        options.inputType= VrPanoramaView.Options.TYPE_STEREO_OVER_UNDER;
        vr.loadImageFromBitmap(bitmap,options);
        super.onPostExecute(bitmap);

    }
};
voidVoidBitmapAsyncTask.execute();

5.与aciivity生命周期同步

onpause supper前:mVrPanoramaView.pauseRendering();

onresume supper后: mVrPanoramaView.resumeRendering();

//关闭渲染视图
ondestory supper前:

           //关闭渲染试图

            mVrPanoramaView.shutdown();
        if(mImagerLoaderTask != null){
            //在退出activity时,如果异步任务没有取消,就取消
            if(!mImagerLoaderTask.isCancelled()){
                mImagerLoaderTask.cancel(true);
            }
        }
