android socket服务端 接收Delphi socket客户端发来的图片，保存到bitmap中，代码如下：

 

public static Bitmap readInputStreamToBitmap(InputStream ins, int fileSize) {  	    if (ins == null) {  	        return null;  	    } 	    byte[] b;	    ByteArrayOutputStream bos = new ByteArrayOutputStream();  	    try {  	        byte[] buffer = new byte[1024];  	        int size = -1;  	        int len = 0;// 已经接收长度	        size = ins.read(buffer);	        while (size != -1) { 	        	len = len + size;//	            bos.write(buffer, 0, size);  	            if (fileSize == len) {// 接收完毕								break;		    }		   size = ins.read(buffer);	        }  	        b = bos.toByteArray();	        bos.close();	    } catch (IOException e) {  	        e.printStackTrace();  	        return null;  	    }  	    if (b.length != 0) {              return BitmapFactory.decodeByteArray(b, 0, b.length);          }          return null;	     	}
