动态图像视图。指定的 child 已经有 parent

Question

我正在尝试添加动态图像。

这是我遇到的错误

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

我也加

  ((ViewGroup)imageView.getParent()).removeView(imageView);

但没有解决我的问题

    @Override
    protected void onActivityResult ( int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
            if (requestCode == ConstantsCustomGallery.REQUEST_CODE && resultCode == Activity.RESULT_OK && data != null) {

                ArrayList<Image> images = data.getParcelableArrayListExtra(ConstantsCustomGallery.INTENT_EXTRA_IMAGES);


                for (int i = 0; i < images.size(); i++) {
                    filePath = Uri.fromFile(new File(images.get(i).path));
                    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(200, 200);
                    imageView.setLayoutParams(lp);
                    ((ViewGroup)imageView.getParent()).removeView(imageView);
                    Glide.with(MainActivity.this).load(filePath).override(200,200).crossFade().into(imageView);
                    linearLayout.addView(imageView);


                }
                  buttonConfirm.setVisibility(View.VISIBLE);

                progressDialog.setProgress(0);

            }
}

问题是您一次又一次地添加相同的图像视图，这是不可能的。您需要创建新的 ImageVIew 并将其添加到任何您想要的地方

for (int i = 0; i < images.size(); i++) {
    filePath = Uri.fromFile(new File(images.get(i).path));
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(200, 200);
    ImageView iv = new ImageView(context); // context mean YourActivity.this or context object
    iv.setLayoutParams(lp);
    //((ViewGroup)imageView.getParent()).removeView(imageView);
    Glide.with(MainActivity.this).load(filePath).override(200,200).crossFade().into(iv);
    linearLayout.addView(iv);
}

动态图像视图。指定的 child 已经有 parent

Dynamic imageView. Specified child already has parent

java

android

android-layout

android-linearlayout

android-relativelayout
