Is there a super simple List / ListAdapter example out there for android


I have a web service that returns a super simple list of objects

MyObject[] data = webServiceCall();

MyObject has 1 field i want to display, "Name" (i.e. data[0].Name )

How can i turn this into an activity that lists just the name of these objects in a scrollable listActivity on Android. I am getting really confused with Cursors and am not sure if I need Cursors and I"m not sure what kind of adapter to implement (BaseAdapter, SimpleAdapter etc)

So i guess i'm looking for three things,

the activity, the adapter and the layout.xml

Just trying to figure this android stuff out, definitely a noob here


Solution

  • so i think i figured it out with a little inspiration from RobGThai's answer, i'm posting the code for anyone else to see, i guess i didn't really use a custom adapter

    This is the super simple example that got me started, so once i had this, I made sure my "MyObject" had a toString() method on it to show properly in the list and i passed the MyObject[] array into the "new ArrayAdapter" constructor instead of listItems

    FooList.java

    import android.app.ListActivity;
    import android.os.Bundle;
    import android.widget.ArrayAdapter;
    
    public class FooList extends ListActivity {
        String[] listItems = {"item 1", "item 2 ", "list", "android", "item 3", "foobar", "bar", }; 
        @Override
         public void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             setContentView(R.layout.temp);
             setListAdapter(new ArrayAdapter(this,  android.R.layout.simple_list_item_1, listItems));
         }
    
    }
    

    the layout xml i used (temp.xml)

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="fill_parent"
        android:layout_height="fill_parent">
        <ListView android:id="@android:id/list" android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <TextView android:id="@android:id/empty" android:layout_width="wrap_content"
            android:layout_height="wrap_content" android:text="Empty set" />
    </LinearLayout>
