1、发送图片+文字

要特别注意，图片的文件名要为 pic 才会被新浪接收。

              Map map = new HashMap();
	   map.put("source", "appkey");//改成自己的key
	   map.put("status", txt);
	   postImg("http://api.t.sina.com.cn/statuses/upload.json",map,Environment.getExternalStorageDirectory()+ "/temp.jpg"
								,"帐号名字","密码");

              /**
	 * 直接通过HTTP协议提交数据到服务器,实现表单提交功能
	 * @param actionUrl 上传路径
	 * @param params 请求参数 key为参数名,value为参数值
	 * @param filename 上传文件
	 * @param username 用户名
	 * @param password 密码
	 */
	private void postImg(String actionUrl,Map<String, String> params, String  filename,String username,String password) {
		try {
			String BOUNDARY = "--------------et567z"; //数据分隔线
			String MULTIPART_FORM_DATA = "Multipart/form-data";  

			URL url = new URL(actionUrl);
			HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 

			conn.setDoInput(true);//允许输入
			conn.setDoOutput(true);//允许输出
			conn.setUseCaches(false);//不使用Cache
			conn.setRequestMethod("POST");
			conn.setRequestProperty("Connection", "Keep-Alive");
			conn.setRequestProperty("Charset", "UTF-8");
			conn.setRequestProperty("Content-Type", MULTIPART_FORM_DATA + ";boundary=" + BOUNDARY);
			String usernamePassword=username+":"+password;
			conn.setRequestProperty("Authorization","Basic "+new String(SecBase64.encode(usernamePassword.getBytes())));

			StringBuilder sb = new StringBuilder();  

			//上传的表单参数部分，格式请参考文章
			for (Map.Entry<String, String> entry : params.entrySet()) {//构建表单字段内容
				sb.append("--");
				sb.append(BOUNDARY);
				sb.append("\r\n");
				sb.append("Content-Disposition: form-data; name=\""+ entry.getKey() + "\"\r\n\r\n");
				sb.append(entry.getValue());
				sb.append("\r\n");
			}
			//            System.out.println(sb.toString());
			DataOutputStream outStream = new DataOutputStream(conn.getOutputStream());
			outStream.write(sb.toString().getBytes());//发送表单字段数据
			byte[] content = readFileImage(filename);
			//上传的文件部分，格式请参考文章
			//System.out.println("content:"+content.toString());
			StringBuilder split = new StringBuilder();
			split.append("--");
			split.append(BOUNDARY);
			split.append("\r\n");
			split.append("Content-Disposition: form-data;name=\"pic\";filename=\"temp.jpg\"\r\n");
			split.append("Content-Type: image/jpg\r\n\r\n");
			System.out.println(split.toString());
			outStream.write(split.toString().getBytes());
			outStream.write(content, 0, content.length);
			outStream.write("\r\n".getBytes());  

			byte[] end_data = ("--" + BOUNDARY + "--\r\n").getBytes();//数据结束标志
			outStream.write(end_data);
			outStream.flush();
			int cah = conn.getResponseCode();
			//            if (cah != 200) throw new RuntimeException("请求url失败:"+cah);
			if(cah == 200)//如果发布成功则提示成功
			{
				/*读返回数据*/
				//String strResult = EntityUtils.toString(httpResponse.getEntity()); 

				new AlertDialog.Builder(Main.this)
				// Main.this视情况而定，这个一般是指当前显示的Activity对应的XML视窗。
				.setTitle("")// 设置对话框的标题
				.setPositiveButton("确定",// 设置对话框的确认按钮
						new DialogInterface.OnClickListener() {// 设置确认按钮的事件
					public void onClick(DialogInterface dialog, int which) {

					}})
					.setMessage(" 发布成功 ")// 设置对话框的内容
					.show();
			}
			else if(cah == 400)
			{
				new AlertDialog.Builder(Main.this)
				// Main.this视情况而定，这个一般是指当前显示的Activity对应的XML视窗。
				.setTitle("")// 设置对话框的标题
				.setPositiveButton("确定",// 设置对话框的确认按钮
						new DialogInterface.OnClickListener() {// 设置确认按钮的事件
					public void onClick(DialogInterface dialog, int which) {

					}})
					.setMessage(" 发布失败  \n 不可连续发布相同内容 ")// 设置对话框的内容
					.show();
			}else{
				throw new RuntimeException("请求url失败:"+cah);
			} 

			//            InputStream is = conn.getInputStream();
			//            int ch;
			//            StringBuilder b = new StringBuilder();
			//            while( (ch = is.read()) != -1 ){
			//                b.append((char)ch);
			//            }
			outStream.close();
			conn.disconnect();
		}
		catch (IOException e)
		{
			e.printStackTrace(); 

		}
		catch (Exception e)
		{
			e.printStackTrace();  

		}  

	}

             public static byte[] readFileImage(String filename) throws IOException {
		BufferedInputStream bufferedInputStream = new BufferedInputStream(
				new FileInputStream(filename));
		int len = bufferedInputStream.available();
		byte[] bytes = new byte[len];
		int r = bufferedInputStream.read(bytes);
		if (len != r) {
			bytes = null;
			throw new IOException("读取文件不正确");
		}
		bufferedInputStream.close();
		return bytes;
	}

2、只发文字

  //POST发布文本信息
	    public  void sendMsg(String status,String username,String password){
			HttpClient httpclient = new DefaultHttpClient();
	        HttpPost httppost = new HttpPost("http://api.t.sina.com.cn/statuses/update.json");
		        //NameValuePair实现请求参数的封装

		        List  params = new ArrayList ();
		        params.add(new BasicNameValuePair("source", "4016954419"));
		        params.add(new BasicNameValuePair("status", status));
		        try
		        { 

		          //添加请求参数到请求对象

		        	httppost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
		        	httppost.getParams().setBooleanParameter(CoreProtocolPNames.USE_EXPECT_CONTINUE, false); 

		        	String data=username+":"+password;
		        	httppost.addHeader("Authorization","Basic "+new String(SecBase64.encode(data.getBytes())));
		        	httppost.addHeader("Content-Type", "application/x-www-form-urlencoded");

		          //发送请求并等待响应
		          HttpResponse httpResponse = new DefaultHttpClient().execute(httppost);
		          //若状态码为200 ok
		          if(httpResponse.getStatusLine().getStatusCode() == 200)
		          {
		            //读返回数据
		            //String strResult = EntityUtils.toString(httpResponse.getEntity()); 

		            new AlertDialog.Builder(Main.this)
					// Main.this视情况而定，这个一般是指当前显示的Activity对应的XML视窗。
					.setTitle("")// 设置对话框的标题
					.setPositiveButton("确定",// 设置对话框的确认按钮
				    new DialogInterface.OnClickListener() {// 设置确认按钮的事件
				        public void onClick(DialogInterface dialog, int which) {

				    }})
					.setMessage(" 发布成功 ")// 设置对话框的内容
					.show();
		          }
		          else if(httpResponse.getStatusLine().getStatusCode() == 400)
		          {
		        	  new AlertDialog.Builder(Main.this)
						// Main.this视情况而定，这个一般是指当前显示的Activity对应的XML视窗。
						.setTitle("")// 设置对话框的标题
						.setPositiveButton("确定",// 设置对话框的确认按钮
				    new DialogInterface.OnClickListener() {// 设置确认按钮的事件
				        public void onClick(DialogInterface dialog, int which) {

				    }})
						.setMessage(" 发布失败  \n 不可连续发布相同内容 ")// 设置对话框的内容
						.show();
		          } 

		        }
		        catch (ClientProtocolException e)
		        {
		          e.printStackTrace();
		          et.setText(et.getText()+" Error1:"+e.getMessage());
		        }
		        catch (IOException e)
		        {
		          e.printStackTrace();
		          et.setText(et.getText()+" Error2:"+e.getMessage());
		        }
		        catch (Exception e)
		        {
		          e.printStackTrace();
		          et.setText(et.getText()+" Error3:"+e.getMessage());
		        }  

		 }

3、加密类 SecBase64.java

package wizzer.cn.app;

如果是放在ImagweView上面的图片呢？
那上面的图片可以是同过相机拍摄设置上去的啊，
怎样获得他们的路径 ?

  阅读下源代码，拍照后存为临时图片，路径是你自定义的。
