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: ``` 02-20 16:40:24.967: E/Trace(1715): error opening trace file: No such file or directory (2) 02-20 16:40:25.819: W/ResourceType(1715): No package identifier when getting value for resource number 0x000020d0 0…

Accepted Answer

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