Don't quite understands the situation. But here is a short example if you
extends from BaseAdapter and implement in the same line. This is using a
layout called custom_view (copied bellow). This code is from an Activity
and can be on the onCreate (The activity must have a ListView called
listView1
Experiment with different Adapters until you find the one that works better
for you, all do basically the same but may require less code, depending on
how much flexibility you need.
ListView list = (ListView)findViewById(R.id.listView1);
list.setAdapter(new BaseAdapter(){
private String values[] = new String[]
{"VALUE1","VALUE2","VALUE3","VALUE4","VALUE5",
"VALUE6", "VALUE7" };
public int getCount() {
return values.length;
}
public Object getItem(int position) {
return values[position];
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup
parent) {
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.custom_view,null);
TextView tvLine1 = (TextView)view.findViewById(R.id.textView1);
TextView tvLine2 = (TextView)view.findViewById(R.id.textView2);
tvLine1.setText(values[position]);
tvLine2.setText("Line2" + values[position]);
return view;
}
});
*File: custom_view.xml*
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android";
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"

<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text"

<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
