alsa_aplay not recording on android

I have just started working on android and I am trying to understand how android audio sub-system (alsa) works. I am running an android image in virtual-box running on windows-7 (64 bit). I was fiddling with alsa-utils to record sound. I tried alsa_aplay -C -f S16_LE -c 2 -r 44100 -d 5 foo.wav it said something like: Recording WAVE foo.wav : Signed 16 bit little endian, rate 44100, stereo However, the output file created appears to be blank (after the wav file header). od -x foo.wav 0000000 4952 4646 7574 000d 4157 4556 6d66 2074 0000020 0010 0000 0001 0002 ac44 0000 b110 0002 0000040 0004

ubuntu安装vbox虚拟机 一、安装准备 1、查看主机配置 a、下载virtualbox安装包 下载链接https://www.virtualbox.org/wiki/Linux_Downloads b、增强功能安装包 根据需求下载需要的系统镜像,链接不含激活码 ) 下载链接https://msdn.itellyou.cn/ 注意:根据你当前使用操作系统,选择需要的安装包。 三、配置虚拟机 3.1、安装virtualbox,在终端下输入 rise@lenovo:~$ sudo apt install update 注:安装程序包依赖报错处理,在终端下输入 rise@lenovo:~$ sudo apt install -f 3.2、配置虚拟机 3.2.1创建虚拟机局域内网( 仅主机模式,此模式并非必须是必须设定参数 ) 3.2.2 新建虚拟机,填写虚拟机名称、选择虚拟机类型和版本。( 请参考实际情况 ) 3.2.3 修改虚拟机内存( 如果主机内存大,可以多分配一些给虚拟机 ) 3.2.4 修改存储空间大小和位置 3.2.5 修改虚拟机配置 3.2.6 加载虚拟镜像和增强包 3.2.7 添加仅主机模式( 不使用仅主机模式(局域内网),可以不用设定 ) 3.2.8 启动虚拟主机,配置window xp,系统启动后,安装增强包,使文件可以直接托放。(

Java开发笔记(一百四十五)FXML布局的伸展适配

匿名 (未验证) 提交于 2019-12-02 21:52:03
前面介绍了FXML的基本格式及其控制器的用法,算是打通了FXML方式的编码流程。程序界面通常保持固定尺寸,不过有时也允许用户拖曳窗口大小,不拖不打紧,一拖就可能坏事。像之前的登录窗口,没拖的时候界面如下图所示。 现在开始慢慢把窗口拖长,拖到一半停下来,此时登录界面如下图所示。 乍看过去,界面上的各控件大小保持不变,且始终居中显示,没发现什么问题。可是继续拖长窗口,突然之间这些控件乾坤大挪移,用户名区域顶到了第一行,登录按钮跟着顶到了第二行,变化后的界面效果如下图所示。 之所以出现控件排版错乱的问题,是因为该界面的根节点采用了流式窗格FlowPane。所谓流式,指的是从左到右排列,倘若没排满一行,就跟在当前行后面;只有排满了一行,才会另起一行继续排。刚刚拖拉窗口的时候,拖得太长了,导致窗口的宽度能够容纳登录类型与用户名两个区域,结果两块区域便挤到同一行了。显然这不是期望的界面布局,至少控件要老老实实呆在自己的位置,不可越雷池一步。 若想避免流式窗格排版飘忽的问题,可以使用垂直箱子VBox替换流式窗格,垂直箱子规定它的每个直接下级都占用一行,绝对不会产生两个直接下级挤在同一行的现象。于是修改原来的fxml文件,把根节点FlowPane换成VBox,对应的xml标签变为以下格式: <VBox fx:controller = "com.javafx.fxml.LoginController

I am looking for a solution to add node's with fade-in or flipping or any animation. Thanks for any help. I found the same question but without any further help here: Animated component adding-delete in a VBox As jewelsea already mentioned, you would use Transitions. Here is an example of how to do it for your use case : public static void addFadingIn(final Node node, final Group parent) { final FadeTransition transition = new FadeTransition(Duration.millis(250), node); transition.setFromValue(0); transition.setToValue(1); transition.setInterpolator(Interpolator.EASE_IN); parent.getChildren()
