在BlackBerry 5.0中显示静态Google Map图像 [英] Display static Google Map image in BlackBerry 5.0

问题描述

我有一个非常有趣的问题需要解决：

我得到一个静态的Google地图图片，其URL为 this 。

我试过几种方法来获取这些信息：
将远程资源作为ByteArrayOutputStream获取，将图像存储在模拟器的SD中，等等......但每当 freaking 时，我都会收到一个 IlegalArgumentException 。

我总是得到一个200 http响应和正确的MIME类型（image / png），但是无论如何：获取图像并将其转换为位图，或者将图像存储在SD中并稍后阅读;我得到了相同的结果...文件总是损坏。

我真的相信它的一个编码问题，或者读取方法（类似于这个）：

p>

  public static Bitmap downloadImage（InputStream inStream）{
 byte [] buffer = new byte [256]; 
 ByteArrayOutputStream baos = new ByteArrayOutputStream（）; 
 while（inStream.read（buffer）！= -1）{
 baos.write（buffer）; 
} 
 baos.flush（）; 
 baos.close（）; 
 
 byte [] imageData = baos.toByteArray（）; 
位图bi = Bitmap.createBitmapFromBytes（imageData，0，imageData.length，1）; 
 //位图bi = Bitmap.createBitmapFromBytes（imageData，0，-1，1）; 
返回bi; 
} 
  

唯一想到的就是imageData.lenght（在响应中，内容长度是：6005），但我真的无法弄清楚这一点。
任何帮助都比欢迎...

解决方案

试试这种方式：

  InputStream input = httpConn.openInputStream（）; 
 byte [] xmlBytes = new byte [256]; 
 int len = 0; 
 int size = 0; 
 StringBuffer raw = new StringBuffer（）; 
 while（-1！=（len = input.read（xmlBytes）））
 {
 raw.append（new String（xmlBytes，0，len））; 
 size + = len; 
} 
 value = raw.toString（）; 
 byte [] dataArray = value.getBytes（）; 
 EncodedImage位图; 
 bitmap = EncodedImage.createEncodedImage（dataArray，0，dataArray.length）; 
最终位图googleImage = bitmap.getBitmap（）; 
  

I'm having a really interesting problem to solve:

I'm getting a static google map image, with an URL like this.

I've tried several methods to get this information: Fetching the "remote resource" as a ByteArrayOutputStream, storing the Image in the SD of the Simulator, an so on... but every freaking time I get an IlegalArgumentException.

I always get a 200 http response, and the correct MIME type ("image/png"), but either way: fetching the image and converting it to a Bitmap, or storing the image in the SD and reading it later; I get the same result... the file IS always corrupt.

I really belive its an encoding problem, or the reading method (similar to this one):

public static Bitmap downloadImage(InputStream inStream){
  byte[] buffer = new byte[256];
  ByteArrayOutputStream baos = new ByteArrayOutputStream();
  while (inStream.read(buffer) != -1){
    baos.write(buffer);
  }
  baos.flush();
  baos.close();

  byte[] imageData = baos.toByteArray();
  Bitmap bi = Bitmap.createBitmapFromBytes(imageData, 0, imageData.length, 1);
  //Bitmap bi = Bitmap.createBitmapFromBytes(imageData, 0, -1, 1);
  return bi;
}

The only thing that comes to mind is the imageData.lenght (in the response, the content length is: 6005 ), but I really can't figure this one out. Any help is more than welcome...

解决方案

try this way:

InputStream input = httpConn.openInputStream();
byte[] xmlBytes = new byte[256];
int len = 0;
int size = 0;
StringBuffer raw = new StringBuffer();
while (-1 != (len = input.read(xmlBytes))) 
{
    raw.append(new String(xmlBytes, 0, len));
    size += len;
}
value = raw.toString();
byte[] dataArray = value.getBytes(); 
EncodedImage bitmap;
bitmap = EncodedImage.createEncodedImage(dataArray, 0,dataArray.length);
final Bitmap googleImage = bitmap.getBitmap();
