我正在制作一个 android 应用程序，在其中我将动态行添加到表布局中，但它只添加了 5 行，然后它给出了异常：
java.lang.IllegalStateException：指定的孩子已经有一个父母。
您必须首先在孩子的父母上调用 removeView()。
我正在使用以下代码：
if(profileimage.equals("")){}

profileimage1.setTextColor(Color.BLACK);

imageUrl=imageUrl+profileimage;
System.out.println(imageUrl);
ImageView image= new ImageView(this);
image.setImageBitmap(DownloadFile(imageUrl));
System.out.println(image.toString());
image.setPadding(20, 10, 0, 0);
tr.addView(profileimage1, lp);
tr.addView(image);

而且图像也没有被下载和显示。但是用于下载图像的相同方法正在其他类中工作。谁能帮我解决这个问题？
