Android Display Html In A Listview

Sorry if this is obvious to everyone else but I am having a minor difficulty understanding how to display html inside my listview. My list view is declared. ListView lv1 = (List

Solution 1:

Ok, so Jitendra Sharma was had the right idea for my scenario, but I needed to override the getView method. Or at least that is what worked for me. Then in the getView method I was able to set my text to render in html.

            ArrayAdapter<String> adapter = newArrayAdapter<String>(SearchByFood.this, R.layout.new_list_view, arr_sort)
            {
                @Overridepublic View getView(int position, View convertView, ViewGroup parent) 
                {
                    View row;

                    if (null == convertView) {
                    row = mInflater.inflate(R.layout.new_list_view, null);
                    } else {
                    row = convertView;
                    }

                    TextViewtv= (TextView) row.findViewById(android.R.id.text1);
                    tv.setText(Html.fromHtml(getItem(position)));
                    //tv.setText(getItem(position));return row;
                }

            };
            lv1.setAdapter(adapter);

Solution 2:

override getItem method of the Adapter and do the following:

ArrayAdapter<String> adapter= ArrayAdapter<String>(SearchByFood.this, R.layout.new_list_view, arr_sort){
     publicObjectgetItem(int position)
     {
          returnHtml.fromHtml(arr_sort.get(position));
     }
};

Solution 3:

If you are using a SimpleAdapter, here is the code that enables HTML on a TextView.

adapter.setViewBinder(newSimpleAdapter.ViewBinder() {  
    publicbooleansetViewValue(View view, Object data, String textRepresentation) {  
        if (data instanceofSpanned && view instanceofTextView) {  
            ((TextView) view).setText((Spanned) data);  
        } else {  
            ((TextView) view).setText(Html.fromHtml(String.valueOf(data))); 
        }  
        returntrue;  
        }  
    }  
);

Solution 4:

If all you wanted is to display some text where parts of the text should be bold, all you need is one TextView, and properly formatted text (with <b> added) and do the following:

textview.setText(Html.fromHtml(text));

For more information on what TextView+Html can support, see here

Solution 5:

If you have the possibility of loading your texts from strings.xml, adding the tag there will automatically bold your text. If however your texts are dynamic, you will have to create a custom adapter, and in it to set the text using textView.setText(Html.fromHtml(yourText));
