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

The LOGCAT:

Answer 1

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 

Answer 2

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; }
