Unable to start activity:UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

Question

I want to write a ListView in basic format but I get an error:

UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

and:

androidview.LayoutInfalater.inflate(LayoutInflater.java: some numbers....like 720,658...so on)

I know something should be done here in the adapter class:

public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    RelativeLayout rv = new RelativeLayout(c);

    TextView tv = new TextView(c);
    TextView tv1 = new TextView(c);
    ImageView imgv = new ImageView(c);

    tv.setText(s[position]);
    tv1.setText(i[position]);
    imgv.setImageResource(d[position]);

    rv.addView(tv);
    rv.addView(tv1);
    rv.addView(imgv);
    return rv;

}

What should I do to solve the problems

Seems like you're not showing us the important part of your code. addView on AdapterView is not supported, because AdapterView is kind of abstract base for ListView, Gallery and so on. See: [link](http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/1.5_r4/android/widget/AdapterView.java). Maybe you should just use a ListView? — Zielony, Feb 20 '13 at 11:12
which one the java or the adapter class code or the 2 layout's code??? — elegance, Feb 20 '13 at 11:16

what should i do???

Correct your code.

UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

A subclass of AdapterView like a ListView can't have children manually added either in the layout file or added in code. So if you have this in one of your layouts:

<ListView // .. other attributes>
     <// other views <-- notice the children of the ListView tag
</ListView>

don't do it, as this will call the addView method of ListView, throwing the exception. Instead use:

<ListView // .. other attributes />
< // other views

You also can't use any of the addView methods of ListView in code like this:

listViewReference.addView(anotherView); // <-- don't do it

Also, if you use the LayoutInflater.inflate method in the code of the Activity or the adapter(its getView method), don't pass the ListView as the second parameter. For example, don't use:

convertView  = inflator.inflate(R.layout.child_rows, parent);

as in Tamilarasi Sivaraj's answer as that will throw the exception again. Instead use:

convertView  = inflator.inflate(R.layout.child_rows, parent, false);

Related to the exception you posted in the question, it appears you use the setText method with an int(one of the s or i arrays being an int array). The problem is that in this case TextView will think you're trying to set the text using a string resource like this R.string.astring. The int you pass is not a string resource so an exception will be thrown. If s or i is an int and you're trying to show it in the TextView use this instead:

tv.setText(String.valueOf(s[position])); // assuming s is the int array

+1 for the "Also, if you use the LayoutInflater.inflate method in the code of the Activity or the adapter(its getView method), don't pass the ListView as the second parameter" — Mushtaq Jameel, Aug 06 '14 at 11:05
The part that was not directly answering the question, solved my problem! (inflation) — AmiNadimi, Jul 15 '19 at 11:46
So what's the correct way to do this if addView() doesn't work in code? — Heinzlmaen, Dec 03 '19 at 15:08
Thank you for the: `convertView = inflator.inflate(R.layout.child_rows, parent, false);` — Matthew Cawley, May 23 '20 at 00:53

Replace your layout in inflater

 @Override
public View getView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub

    if (convertView == null) {

        LayoutInflater inflater = (LayoutInflater) LayoutInflater
                .from(contex);
        convertView = inflater.inflate(R.layout.your_layout, parent, false);

    }

    txtName = (TextView) convertView.findViewById(R.id.txtName);
    txtName.setText(""+ContactsArr.get(position).get("ContName"));
    txtPhoneNumber = (TextView) convertView.findViewById(R.id.txtContact);
    txtPhoneNumber.setText(""+ContactsArr.get(position).get("ContPhone"));

    return convertView;
}

If you're like me and totally skipped over the answer I needed in @Luksprog's answer because it's buried in it, try using adding the third parameter to the inflate method, also mentioned here:

inflater.inflate(R.layout.group_row, parent, false);

Don't use true instead of false or you will get the same error that brought you here, because it's trying to attach/add it to the parent, hence the addView is not supported in AdapterView error.

Try this Like this:

public static class ViewHolder {
    public ImageView imageView;
    public TextView textView; 

    public View getView(int position, View convertView, ViewGroup parent) {
        try{
            ViewHolder holder;

            if (convertView == null)  {
                holder = new ViewHolder(); 
                LayoutInflater inflater = context1.getLayoutInflater();
                convertView = inflater.inflate(R.layout.your_layout, null,true);  

                holder.imageView = (ImageView) convertView.findViewById(R.id.imgview);

                holder.textView = (TextView) convertView.findViewById(R.id.txtview);

                convertView.setTag(holder);  
            } else {
                holder = (ViewHolder) convertView.getTag();  
            }

            holder.textView.setText("your text");
            holder.imageView.setImageResource("your image resource");
        } catch (Exception e) {
            System.out.println("Error: "+e);    
        }

        return convertView;
    }
}

Tamilarasi Sivaraj, should i put my tex t view and img view in the place of the child view??? — elegance, Feb 20 '13 at 11:23
yes you put your textview and image view in the child view and mention the layout name in LayoutInflater...if you have any queries ask me — Android_coder, Feb 20 '13 at 11:26
i have edited my code for put textview and imageview from layout to listview using adapter use it... — Android_coder, Feb 20 '13 at 11:41

I also received the issue :

android.view.InflateException: Binary XML file line #2: addView(View, LayoutParams) is not supported in AdapterView Caused by: java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

I have forgotten to add "false" when I inflate the .xml. After adding that it works. My code phrase is as below. I used a LinearLayout for my .xml.

if(convertView == null){
        convertView = LayoutInflater.from(getContext()).inflate(R.layout.row_format,parent,false);
    }
