I watched thenewboston tutorials and there is something I didnt understood. I didnt understand how the MainActicty knows what CustomListView to use-we arent pass any info about it. The only info is the context and the string array that we set-up at the MainActivty. ( [this video] 9:01) it's looks like he took the name of the array from the custom_row but I checked it and this is the MainActivty. public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String [] names = {"a"," b","c", "d", "e"}; ListAdapter elichaiAdapter = new CustomAdapter(this , names); ListView elichai

I'm trying to make a ListView of a grocery list in which clicking on any of the buttons alters the quantity of the particular item.

I have been trying to create a ListView and I have succeded in creating one. However my ListView now uses the same icon for every item in the list. When I have been searching for answers people have just showed examples of lists with less than 10 items. But my list contains well over a 100 items. For the text I just created a string-array in my string.xml, and retrieved them using Resources res = getResources(); String[] list_of_names = res.getStringArray(R.array.names); But how do I do the same with icons?

I was following a NewBoston Tutorial ( [this video] ) He showed how to put an image into a list but he never showed how to assign a different image to every piece of text. Here is my MainActivity . public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); String[] Jobsites = {"River Park Place", "Mayfair", "Jameson House"}; ListAdapter jobsiteAdapter = new CustomAdapter(this, Jobsites); ListView jobsiteListView = (ListView) findViewById(R.id.jobsiteListView); jobsiteListView.setAdapter(jobsiteAdapter); jobsiteListView.setOnItemClickListener( new AdapterView.OnItemClickList
