Change the selected item font size in listview android

Question

In my list view inflator i have an image and a textview. When the user selects the any item in the listview, I want to increase the font size of the text in the textview. I am using a custom adapter. Can I do this in getview method ? And also is it possible to do this without calling notifydatasetchanged() always ?

you should use design pattern `Holder` to full control over elements in `ListView`, without it you are not able to do it. This solution is cleanest and right programmatically written. — Simon Dorociak, May 28 '12 at 12:45

You can use setTag() and getTag().

setTag() in your adapter's getView()

@Override
public View getView(int position, View convertView, ViewGroup parent) {

    convertView=  getLayoutInflater().inflate(R.layout.layoutfile, null);
    TextView mTextViewNumber= (TextView) convertView.findViewById(R.id.TvId);
    ImageView mImageView= (ImageView) convertView.findViewById(R.id.ImgId)
    mTextViewNumber.setText("Hi hello");
    mImageView.setBackgroundResource(R.x.xxxx);
    convertView.setTag(mTextViewNumber, R.id.TvId);
    convertView.setTag(mImageView, R.id.ImgId);
    return convertView;
}

Change the Textsize by getTag() OnItemClickListener().

mListView=(ListView) findViewById(R.id.list_call_log_listview);
mListView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> arg0, View view, int arg2,
                    long arg3) {
        TextView mTextView= (TextView) view.getTag(R.id.TvId);
        mTextView.setTextSize(20);
        ImageView mImageView= (ImageView) view.getTag(R.id.ImgId);
        mImageView.setBackgroundResource(R.x.xxxx);
    }

});

Thanks for your reply. Apart from changing the textsize I also have to change the background of the image when it is selected. (My inflator has a textview and a imageview). How can i use gettag() and settag() for multiple items ? And if i use the above code will i need to call notifydatasetchaged() ? Because i don't want to call it. – BlackberryChennai May 28 '12 at 12:55
see me answer again, made the changes for multiple control. – Mohammed Azharuddin Shaikh May 28 '12 at 12:59
Thanks this works, but after i click on an item a popup is shown. After coming back from the pop up the size is still big. I want it be become normal. – BlackberryChennai May 28 '12 at 13:57
take TextView and ImageView global, when return back from dialog change them normal. – Mohammed Azharuddin Shaikh May 28 '12 at 14:01

I think you can use this in your onItemClick method it's rather simple solution

View v=myListView.getChildAt(position);
TextView tv=(TextView)v.findViewById(R.id.myTextView);
tv.setTextSize(...);
