ListView & Custom ListView

I need help on how to change my code below to use my own XML list view. The items 'label', 'title', & 'discription' in my cursor needs to be inflated into itemLabel, itemTitle, & itemDiscription of the xml. Any help would be appreciated: I know how to do this from a simple array. The activity I created to get the data from a database works great - I just dont know how to use/display a custom lisView w/multilines. THNX!

REVISED: I managed to get the data to display from the database using my own custom XML file. The issue I have now is all three columns are returned in each TextView. ie: columns 'title', 'label', 'description' from the db all inflate into a single TextView as one continuous line. I cant figure out how to break it up into the correct TextViews; title = R.id.listTitle, label = R.id.label, and description should inflate into R.id.caption. Help!

The ListView Activity:(REVISED):

public class List_AC extends ListActivity {

private ArrayList<String> results = new ArrayList<String>();

File dbfile = new File("/mnt/sdcard/XXX/XXX/dB/XXX.db");
SQLiteDatabase db = SQLiteDatabase.openOrCreateDatabase(dbfile, null);

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    openAndQueryDatabase();
    displayResultList();
}

private void displayResultList() {
    AC_Adapter adapter = new AC_Adapter(getApplicationContext(),R.layout.list_item, results, results, results);
    setListAdapter(adapter);
}

private void openAndQueryDatabase() {
    try {
        Cursor c = db.rawQuery("SELECT label, title, discription FROM AC_list", null);
        if (c != null) {
            if (c.moveToFirst()) {
                do {
                    String i1 = c.getString(c.getColumnIndex("label"));
                    String i2 = c.getString(c.getColumnIndex("title"));
                    String i3 = c.getString(c.getColumnIndex("discription"));
                    results.add(i1 + i2 + i3);
                } while (c.moveToNext());
            }
        }
    } catch (SQLiteException se) {
        Log.e(getClass().getSimpleName(),
                "Could not create or Open the database");
    } finally {
        if (db != null)
            db.close();
    }
}

}

ADDED ADAPTER(AC_Adapter.java):

public class AC_Adapter extends ArrayAdapter<String> {
static List<String> Title = new ArrayList<String>();
static List<String> Label = new ArrayList<String>();
static List<String> Description = new ArrayList<String>();

Context myContext;

public AC_Adapter (Context context, int resource, List<String> aTitle, List<String> aLabel, List<String> aDescription){

    super(context, resource, aTitle);

    myContext = context;
    Title= aTitle;
 开发者_StackOverflow中文版   Label= aLabel;
    Description = aDescription;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;
    if (v == null) {
        LayoutInflater vi = (LayoutInflater) myContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.list_item, null);
    }

    TextView tv_label = (TextView) v.findViewById(R.id.label);
    TextView tv_title = (TextView) v.findViewById(R.id.listTitle);
    TextView tv_decription = (TextView) v.findViewById(R.id.caption);

    if (tv_label != null) {
        tv_label.setText(Label.get(position));
    }
    if (tv_title != null) {
        tv_title.setText(Title.get(position));
    }
    if (tv_decription != null) {
        tv_decription.setText(Description.get(position));
    }

    return v;

}

}

This is the XML that needs to be created (list_view.xml) in the onCreate:

 <?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" >

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="30dip" 
    android:padding="4dip"
    android:background="@drawable/gradient" >

    <ImageButton
        android:id="@+id/homeBtn"
        android:src="@drawable/ic_menu_icon"
        android:layout_width="wrap_content" 
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:background="@null" />

    <TextView
        android:id="@+id/titleBarTitle"
        android:layout_centerInParent="true"
        android:layout_width="wrap_content" 
        android:layout_height="match_parent"
        android:textSize="18sp" />

    <ImageButton
        android:id="@+id/toolBtn"
        android:src="@drawable/ic_menu_list"
        android:layout_width="wrap_content" 
        android:layout_height="match_parent"
        android:layout_alignParentRight="true"
        android:background="@null" />

 </RelativeLayout>

<ListView 
   android:id="@+id/listItems" 
   android:layout_height="wrap_content"
   android:layout_width="fill_parent" />

</LinearLayout>

and the list item (list_item.xml):

<?xml version="1.0" encoding="utf-8"?>

<TextView
    android:id="@+id/itemLabel"
    style="@style/listAcronym" />

<TextView
    android:id="@+id/itemTitle"
    style="@style/listTitle" />

<TextView
    android:id="@+id/itemDiscription"
    style="@style/listDiscription"/>        

<ImageView
    style="@style/listNextIcon" />   

The basic process is to create a Custom Adapter which will contain the layout R.layout.list_item

Thus, you replace this line setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, results)); in your code by

setListAdapter(new CustomAdapter(this,R.layout.list_item, results));

Now you need to create a CustomAdapter which extends ArrayAdapter or BaseAdapter and override the getView method to inflate R.layout.list_item

Please refer to this excellent tutorial by Mark Murphy Custom ListView Adapter

If you do have any other doubts after trying this, please post it over here.

Everything is fine, just add a class extends from ArrayAdapter and do something like this:

public class CustomAdapter extends ArrayAdapter<String>
{
    List<String> Title= new ArrayList<String>();
    List<String> Label= new ArrayList<String>();


    Context myContext;


public CustomAdapter (Context context, int resource,
                                               int textviewresourceid,  
                                               List<String> aTitle,
                                               List<String> aLabel)
{


    super(context, resource,textviewresourceid,aType);

    myContext = context;
    Title= aTitle;
    Label= aLabel;



}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    View v = convertView;
    if (v == null) 
    {
            LayoutInflater vi = (LayoutInflater)myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.list_view, null);
    }

    TextView tv_title = (TextView) v.findViewById(R.id.id_tv_Title);
    TextView tv_Label= (TextView) v.findViewById(R.id.id_tv_Label);


    if(tv_title != null)
    {
        tv_title.setText(Title.get(position));
    }
    if(tv_Label != null)
    {
        tv_Label.setText(Label.get(position));
    }

    return v;


}

And then use this adapter like:

CustomAdapter adapter = new CustomAdapter(getAppContext(),R.layout.list_view,Textview Title Id,your lists...);

setListAdapter(adapter);

Something like this.... Hope it helps...

I have the correct anwser HERE along with the correct code.
