Android-AR眼镜屏幕显示

Android-AR眼镜

前提：Android手持设备 需要具备DP高清口

1、创建Presentation（双屏异显）

public class MyPresentation extends Presentation {
    private PreviewSingleBinding binding;
    private ScanActivity activity;

    public MyPresentation(Display display, ScanActivity activity) {
        super(activity, display);
        this.activity = activity;
    }
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = PreviewSingleBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());
    }

    //业务逻辑
    public void showNotice(UserInfo userInfo, ShowNotice notice){
         //更新界面、处理数据、展示数据等
    }
     

}

2、寻找眼镜显示屏、并将异屏显示在上面

        Object display = this.getSystemService(DISPLAY_SERVICE);

        if (display == null) {
            Toast.makeText(context," 未找到眼镜，请重新插拔！",Toast.LENGTH_SHORT).show();
            return;
        } else {
            DisplayManager manager = (DisplayManager)display;
            boolean temp = false;
            while (!temp){
                Display[] diaplayArr = manager.getDisplays();
                if(diaplayArr.length > 1){
                    presentation = new MyPresentation(
                            diaplayArr[manager.getDisplays().length - 1],
                            this);
                    presentation.show();
                    temp = true;
                }
            }
        }
