How to remove a ImageView inside of LinearLayout

Question

In my app, I select photos from gallery and insert them inside of LinearLayout programmatically, so I did this :

<LinearLayout
            android:orientation="horizontal"
            android:id="@+id/linearImages"
            android:layout_width="wrap_content"
            android:layout_height="150dp">
            <Button
                android:layout_gravity="center"
                android:id="@+id/add_btn"
                android:gravity="center"
                android:drawableLeft="@drawable/add_icon"
                android:layout_marginLeft="10dp"
                android:layout_marginStart="10dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />
        </LinearLayout>

And i'm set a tag to which photo that I'm putting :

public void AddNewImages(Context context,Bitmap bitmap){
    ImageView img = new ImageView(context);
    img.setScaleType(ImageView.ScaleType.FIT_XY);
    img.setImageBitmap(bitmap);
    img.setTag(tagCount);
    linearImages.addView(img);
    bitmapArray.add(bitmap);
    tagCount++;
}

And I want to remove a Image by tapping, as I said before, the Images are added programmatically, so I need something to remove images one by one without have a static Image position.

I would suggest to use RecyclerView instaed of LinearLayout . The reason being you can easily get the position of the item clicked and can remove accordingly. If you want to go with your own solution, then I would suggest to add setOclickListener on each ImageView being added. In the listener after the click event get the imagView.getTag() , which is the position of the image view within LinearLayout . You can then remove the image view from the LinearLayout by using:

ll.removeViewAt(position);// to remove view from particular position

Or if you want to remove ImageView being clicked directly then:

ll.removeView(view)// to remove particular view

Update your code of AddNewImages It will work.

public void AddNewImages(Context context,Bitmap bitmap){
        ImageView img = new ImageView(context);
        img.setScaleType(ImageView.ScaleType.FIT_XY);
        img.setImageBitmap(bitmap);
        img.setTag(tagCount);
        linearImages.addView(img);
        bitmapArray.add(bitmap);
        tagCount++;
        img.setOnClickListener(clickListner);
        View.OnClickListener clickListner=new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                linearImages.removeView(v);
            }
        };
    }
