小编Sag*_*kar的帖子

我是iOS的新手,过去一周在网上寻找教程,例如:处理Exif图像,调整图像大小以及StackOverflow上的更多随机问题,我一直在抨击iOS .从这些,我想,>=iOS 4.0从相机拍摄的所有图像都包含EXIF基于旋转的信息.

什么不起作用:在尝试不同的图像裁剪技术之后,我最终得到的是在一些随机角落处裁剪图像,并且所得到的图像似乎被放大:(当我使用png来自互联网的图像时(其中)包含EXIF数据),裁剪工作正常.通过随机角落,我的意思是 - 图像最终被裁剪在右上角/左上角并放大.

我想要实现的目标:
我正在尝试100 px从顶部和100 px底部裁剪图像.基本上,我使用两个覆盖条 - 顶部1个,底部1个 CGRect(0.0, 0.0, SCREEN_WIDTH, 100.0)[ 100.0 px顶部有一个高条]和另一个CGRect(0.0, SCREEN_HEIGHT - 100, SCREEN_WIDTH, 100.0)[ 100 px底部另一个高条].我需要在这两个条带之间获取图像:我假设图像的高度为:SCREEN_HEIGHT - 200.0.

显示带覆盖的摄像头的UIImagePickerController:

    //SCREEN_HEIGHT = 480 and SCREEN_WIDTH = 320
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];

    if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO) 
    {
        NSLog(@"Camera not available");
        return;
    }

    imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
    imagePicker.delegate = self;
    imagePicker.allowsEditing …

谢谢阅读.

背景: 我正在尝试读取以JSON格式返回数据的流式API提要,然后将此数据存储到pymongo collection.流API需要"Accept-Encoding" : "Gzip"标头.

发生了什么: 代码失败 json.loads 和输出 - Extra data: line 2 column 1 - line 4 column 1 (char 1891 - 5597)(请参阅下面的错误日志)

解析每个JSON对象时不会发生这种情况 - 它是随机发生的.

我的猜测是我在每个"x"正确的JSON对象之后遇到一些奇怪的JSON对象.

如果请求的数据有时被gzip,我确实参考了如何使用pycurl,有时候不是吗？和编码时误差反序列化从谷歌一个JSON对象,但至今一直在解决这个错误是不成功的.

有人可以帮帮我吗？

错误日志: 注意:下面的JSON对象的原始转储基本上是使用repr()打印字符串的原始表示而不解析CRLF/LF的方法.

背景: 我正在为服务器开发一个Android客户端,其中需求是应用程序,需要与 WebSockets基于服务器的服务器来回连续交换消息.

实施:对于客户端,我使用weberknecht的 WebSocket Android客户端库,而服务器是Tornado基于.

问题: 目前,我祈求initWebSocketClient在onCreate通过生成的AsyncTask.但是,我一直收到客户端超时异常.

Android客户端:

private void initWebSocketClient() {
        Log.e(TAG, "initWebSocketClient");
        try {
            URI url = new URI("ws://192.168.207.84:8080/");
            WebSocket websocket = new WebSocketConnection(url);

            // Register Event Handlers
            websocket.setEventHandler(new WebSocketEventHandler() {
                    public void onOpen()
                    {
                            Log.e(TAG, "--open");
                    }

                    public void onMessage(WebSocketMessage message)
                    {
                            Log.e(TAG, "--received message: " + message.getText());
                    }

                    public void onClose()
                    {
                            Log.e(TAG, "--close"); 
                    }
            });

            // Establish WebSocket Connection
            websocket.connect();

            // Send …

例如:

>>> print dt
2012-12-04 19:00:00-05:00

如您所见,我有这个日期时间对象如何将此日期时间对象转换为GMT -5中的纪元秒.

我该怎么做呢？

我对Android动画和手势比较陌生.

我有15张想要滑动的图像.屏幕上一次只显示一个图像,当我在第一张图像上滑动L-> R时,第二张图像显示,依此类推 - 就像幻灯片一样.我查看了Android Gallery教程,但我不希望显示缩略图.我的理解是使用ImageView并不断更改图像.这是正确的方法还是有更好的方法？

谢谢阅读!

一位用户最近报告说他无法在他的华硕Eee Pad变压器上安装我的应用程序(我认为它有3.2更新).

所以,我尝试在3.2模拟器上安装应用程序,这是我的控制台输出:

有人可以帮我解决这个问题吗？:(

问题处理此类错误的最佳方法是什么？比如说,最多30秒后重试.5次？

设置 我在AWS ECS上有一个PRIMARY +两个SECONDARY设置,并且没有任何框已关闭.

从异常消息来看,似乎Mongo说"我没有PRIMARY,我试图从SECONDARY获取数据,但它们也已经失效".但是,没有一个Mongo服务器出现故障.我这有一个默认的另一个进程运行read_preference的SECONDARY,并已被罚款运行.

例外

谢谢阅读!

var data = "<html><head><title>Hello</title></head><body>Hello Body</body></html>";

我想打印data包括HTML标签,而不需要浏览器呈现HTML标签,只显示"Hello Body".

我试过了:

str = str.replace("<", "");

但是徒劳无功

我在哪里可以获得PC的Android iso文件.我想知道下载链接.请告诉我它!

我有一个ScrollView，我想插入一个用户指定数量的Horizo​​ntalScrollViews。因此，用户说他想拥有一个5x5元素的矩阵，我想插入5个Horizo​​ntalScrollViews，每个对象具有5个EditText对象。我的程序按照预期的那样添加了第一行，而其余的则没有。

for (int i = 0; i < number; i++) {
        LinearLayout ll = new LinearLayout(this);
        ll.setLayoutParams(par2);
        HorizontalScrollView row = new HorizontalScrollView(this);
        row.setLayoutParams(par1);
        row.addView(ll);
        for (int j = 0; j < number; j++) {
            EditText txt = new EditText(this);
            txt.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
            txt.setHint(i+","+j);
            ll.addView(txt);
        }
        latout_in_scrollview.addView(row);
    }

有什么想法吗？谢谢！

编辑：使用的1：1代码
