Question

When inflating views for a listView, is it better to have all textViews without android:text in the .xml file and how much does that affects the speed? What about ViewStubs, would that be even faster?

When inflating a LinearLayout with 8 textViews without android:text and with android:text=”@string/abc”, does that change anything ?
note that i am reusing views, so maybe only 10 get inflated and then reused i don’t know.

I am developing on a ZTE Blade, so that’a single 600Mhz CPU and not a quad core …

You can try this, not sure if it will speed up, but give it a shot.

Inflate the layout in a background thread.

View getView(int position, View convertView, ...) {
    View v;
    if (convertView == null) {
        Start a background thread to inflate your linearLayout. 
        Pass item data and view 'v' to it.

        v = inflate a simple dummy textview;
        return v;
    }
    set normal stuff to convertview here.
    return convertView ;
 }

In the background thread,

• Inflate your Linearlayout into 'v'
• Set all the data.

• Then invalidate the view v.

  v.postInvalidate();
