}代码很简单，流程就是获取VrPanoramaView组件——添加事件监听——异步载入图片。panoWidgetView.setFullscreenButtonEnabled(false); // 是否启用全屏按钮 panoWidgetView.setStereoModeButtonEnabled(false); // 是否启用纸盒按钮
//图像被预期以覆盖沿着其水平轴360度，而垂直范围是根据图像的宽高比来计算。例如，如果一个1000x250像素的图像，给出所述全景将覆盖360x90度与垂直范围是-45至+45度。
public static final int TYPE_MONO = 1;
//包含两个大小相等的投影 全景图垂直叠加。顶部图像被显示给左眼、底部图像被显示给右眼。
图像将覆盖沿水平轴360度，而垂直范围是根据图像的宽高比来计算。例如，如果一个1000x500像素的图像中给出（即1000x250像素每个眼睛），全景将覆盖360x90度与垂直范围是-45至+45度。
public static final int TYPE_STEREO_OVER_UNDER = 2;
public static class Options {
private static final int TYPE_START_MARKER = 0;//起始标记
public static final int TYPE_MONO = 1;
public static final int TYPE_STEREO_OVER_UNDER = 2;
private static final int TYPE_END_MARKER = 3;//结束标记
public int inputType = 1;//默认为一

}
void validate() {
if(this.inputType <= 0 || this.inputType >= 3) {//标记错误处理
String var10000 = VrPanoramaView.TAG;
int var1 = this.inputType;
Log.e(var10000, (new StringBuilder(38)).append("Invalid Options.inputType: ").append(var1).toString());
this.inputType = 1;
}
}
}
