How to add custom layout in Arrayadapter?

Question

I am trying to create ListViewwith a custom layout. each item in ListViewshould look like below in item.xml.

in code i used

adapter = new ArrayAdapter<T>(getApplicationContext(), R.layout.listi_tems_layout, topicsList);

but it does not work, because the constructor ArrayAdapter<T>takes the second parameter as intsomething like

android.R.layout.simple_list_item_1

and in my case this is a custom layout that

R.layout.listi_tems_layout

which adapter should i use or how to solve it. thank

ArrayAdapter takes a second parameter as an int something like android.R.layout.simple_list_item_1

getView ArrayAdapter, TextView android:id="@android:id/text1" TextView.

, android:id="@android:id/text1" TextView R.layout.listi_tems_layout.

R.layout.listi_tems_layout TextView, , ArrayAdapter .
