如何将上传的图像从服务器检索到android应用程序,android,json,Android,Json,我将图像作为Base64编码方法上传到服务器,并将其作为字符串发送。我可以从服务器检索该字符串并对其进行解码吗 you have link for that..json parsing ,xml parsing u can get the address and then u can implement that image in ur apps. 公共类LoadImageFromURLActivity扩展活动{ @凌驾 创建时的公共void(Bundle savedInstanceSta

我将图像作为
Base64
编码方法上传到服务器,并将其作为字符串发送。我可以从服务器检索该字符串并对其进行解码吗
you have link for that..json parsing ,xml parsing u can get the address and then u can   implement that image in ur apps.
公共类LoadImageFromURLActivity扩展活动{ @凌驾 创建时的公共void(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.main); //加载程序图像-将在加载图像之前显示 int loader=R.drawable.loader; //要显示的图像视图 ImageView图像=(ImageView)findViewById(R.id.image); //图像url 字符串图像\u url=”http://images4.fanpop.com/image/photos/18900000/Cute-couples-_-love-18948423-500-334.jpg"; //ImageLoader类实例 ImageLoader imgLoader=新的ImageLoader(getApplicationContext()); //每当您想从url加载图像时 //调用DisplayImage函数 //url-要加载的图像url //加载器-加载器图像,将在获取图像之前显示 //图像-图像视图 DisplayImage(图像\ url、加载程序、图像); } }
是否可以检索相同的编码字符串并使用您上传的图像获取图像。现在您尝试在应用程序中使用它…使用Asynctask。。。
