Java错误：指定的子项已经有父项。您必须首先在子级的父级上调用removeView()

我正在制作一个 Android 应用程序，其中我将动态行添加到表格布局中，但它只添加了 5 行，然后给出了异常：

java.lang.IllegalStateException：指定的子级已经有父级。
您必须首先在子级的父级上调用removeView()。

我正在使用以下代码：

                 if(profileimage.equals("")){}
                 else{
            System.out.println("image"+profileimage);
             TableRow tr = new TableRow(this);
             TextView profileimage1= new TextView(this);
             profileimage1.setTextColor(Color.BLACK);
             profileimage1.setText("Profile Image :");
              String imageUrl = "http://ondamove.it/English/images/users/";
                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);

                table.addView(tr, new TableLayout.LayoutParams(

而且图像也不会被下载和显示。但下载图像的相同方法也适用于其他类。 有人能帮我解决这个问题吗？

I am making an android app in which i am adding dynamic rows to a table layout but it adds just 5 rows and then it gives the exception:

java.lang.IllegalStateException: The specified child already has a parent.
You must call removeView() on the child's parent first.

I am using the following code for it:

                 if(profileimage.equals("")){}
                 else{
            System.out.println("image"+profileimage);
             TableRow tr = new TableRow(this);
             TextView profileimage1= new TextView(this);
             profileimage1.setTextColor(Color.BLACK);
             profileimage1.setText("Profile Image :");
              String imageUrl = "http://ondamove.it/English/images/users/";
                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);

                table.addView(tr, new TableLayout.LayoutParams(

您是否尝试过为表行或要添加到表中的视图提供唯一 ID？尝试为这些表行和视图设置 ID。

Have you tried giving an Unique ID for the table rows or the views you are adding to the table ?. Try setId for those table rows and the views.
