項目下載下傳
1、手機端選擇檔案上傳至伺服器端
http://download.csdn.net/detail/u010134178/8457679
2、手機端拍照上傳至伺服器端
http://download.csdn.net/detail/u010134178/8457673
3、總下載下傳位址
http://down.51cto.com/7851921/up
這些都是需要積分的,如果積分不夠的話發送到我郵箱[email protected]我直接把項目發送過來
大家在調試的同時一定要注意
1、網絡下載下傳、上傳這些操作,就是耗時的操作,要另外開線程操作,不能放到主線程裡面。
2、網絡下載下傳、上傳裡面不能有ui操作,不能在裡面顯示ui。就是不能在子線程裡面操作UI。如果操作完畢ui提示使用者等操作,可以使用利用handler結合Thread更新UI,或者AsyncTask異步更新UI。
3、上傳到本地Tomcat伺服器,要關閉防火牆
接下來将給出兩個項目部分代碼,當然兩個項目都有一個工具類HttpPost
