Image dynamique. L'enfant spécifié a déjà un parent

Question

J'essaie d'ajouter des images dynamiques.

Ceci est une erreur que je suis face à

Causée par: java.lang.IllegalStateException: L'enfant spécifié a déjà un parent. Vous devez d'abord appeler removeView() sur le parent de l'enfant.

ajouter également

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

mais n'a pas résolu mon problème

@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); 

      } 
}

problème est que vous ajoutez la même vue de l'image encore et encore ce qui n'est pas possible. vous devez créer ImageVIew et l'ajouter où vous voulez

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); 
}
