我在imageview控件中显示了一个图像，但是当我尝试将图像发送到远程服务器，php服务器时，存储在服务器中的图像是最小化版本，没有在imageview控件中捕获的全尺寸图像

//File finalFile = new File(getRealPathFromURI(tempUri));
dialog = ProgressDialog.show(DisplayImgCamActivity.this, "", "Subiendo imagen...", true);

public void run() {
uploadFile(imagepath);

不知道我是否理解了这个问题，但是你发送的是一个在imageview中加载的图像，并且是一个php，它的大小比imageview中显示的要小，如果是这样的话，那么您在应用程序中拥有的图像很小，如果您可以帮助解决方案，那么会发生相同的缩放图像视图，对不起我的英文
编辑：我的意思是图像的外观如果相同则没有任何修改

好吧，最后我可以结束剧本了。最后，我选择了智能手机中存储图像的完整路径，而不是图像视图中显示的图像。在这种情况下，我可以获得我想要的完整图像。图像视图中显示的图像是存储在手机中的图像的最小化版本。
