Android HttpPost数据中文乱码的解决方案

在项目中，以HttpPost方式向服务器上提交数据时，服务器上中文竟然显示乱码，针对该种情况证明解决呢？其实，这样的问题，在架构的时候，就应该考虑到，如果牵扯到各个不同的平台应用，尽量统一使用UTF8编码，可以少很多麻烦。当然在post数据的时候，可以指定编码，请参阅下面的函数：

	public Map<String, Object> CreateNote(int albumId, String title,
			String remark) {
		String noteId = "";
		Map<String, Object> map = new HashMap<String, Object>();
		try {
			HttpParams parms = new BasicHttpParams();
			parms.setParameter("charset", HTTP.UTF_8);
	                HttpConnectionParams.setConnectionTimeout(parms, 8 * 1000);
	                HttpConnectionParams.setSoTimeout(parms, 8 * 1000);
			HttpClient httpclient = new DefaultHttpClient(parms);
			HttpPost httppost = new HttpPost(ConfigHelper.CreateUri);
			httppost.addHeader("Authorization", mToken);
			httppost.addHeader("Content-Type", "application/json");		
			httppost.addHeader("charset", HTTP.UTF_8);

			JSONObject obj = new JSONObject();
			obj.put("title", title);
			obj.put("categoryId", mCategoryId);
			obj.put("sourceUrl", GetSourceUri());

			JSONArray arr = new JSONArray();

			arr.put(DateFormat.format("yyyyMM",Calendar.getInstance(Locale.CHINA)));		
			obj.put("tags", arr);
			obj.put("content", remark);	
			httppost.setEntity(new StringEntity(obj.toString(), HTTP.UTF_8));
			HttpResponse response;
			response = httpclient.execute(httppost);
			int code = response.getStatusLine().getStatusCode();
			if (code == ConstanDefine.ErrorCode.SuccOfHttpStatusCode) {
				String rev = EntityUtils.toString(response.getEntity());
				obj = new JSONObject(rev);
				noteId = obj.getString("id");
				map.put("return_code", "0");
				map.put("content", rev);			
			}
		} catch (Exception e) {
			if (map.containsKey("return_code")) {
				map.remove("return_code");
			}
			map.put("return_code", "1");		
		}
		return map;
