Curved border for list view


I am newbie to android and java, i need to create a simple application in android. I have a Activity page in this activity. Here is my activity page

import; import; import; import; import; import java.util.ArrayList;
import org.apache.http.client.ClientProtocolException; import org.json.JSONArray; import org.json.JSONException; import org.json.JSONObject;
import; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.ListView;
public class tkcmu extends Activity { private ListView lv1;

@Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); ArrayList<String> listItems = new ArrayList<String>(); try { URL recentUrl = new URL( "To some link"); URLConnection tc = recentUrl.openConnection(); BufferedReader in = new BufferedReader(new InputStreamReader(tc.getInputStream())); String line; while ((line = in.readLine()) != null) { JSONArray ja = new JSONArray(line); for (int i = 0; i < ja.length(); i++) { JSONObject jo = (JSONObject) ja.get(i); listItems.add(jo.getString("content")); } } }catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); }catch (IOException e) { e.printStackTrace(); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } lv1=(ListView)findViewById(; // By using setAdpater method in listview we an add string array in list. lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , listItems)); }


and my main.xml is like this

<?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="wrap_content" android:layout_height="wrap_content" xmlns:android=""> <ListView android:id="@+id/ListView01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:background="@drawable/customshape" android:layout_marginTop="10sp" android:layout_marginLeft="10sp" android:layout_marginRight="10sp" android:drawSelectorOnTop="false" android:cacheColorHint="#FFFFFF" android:clipToPadding="true" android:focusable="true" android:focusableInTouchMode="true" android:clickable="true" android:longClickable="true" android:footerDividersEnabled="true" android:headerDividersEnabled="true" android:dividerHeight="1px" /> </LinearLayout>

and also i have an customshape.xml in drawable which is

<shape xmlns:android=""> <corners android:radius="10dp" /> </shape>

and i got the result with the entire custom list section get curved but i want to get each row with a curved background. I have posted my entire code here(exclude android manifesto.xml) so this will be appreaceated if any body tell me exactly what changes i need to in this code. Any body have an idea about how to implement it.

Thanks in advance

I never done this for rounded corners, but I would try to provide a custom adapter for the list. A custom adapter would allow you to specify which view to use for each item. In your case, you could try to provide a view with a rounded corner borders (defined with a shape XML).

To do this, you would replace the line lv1.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1 , listItems));

with a BaseAdapter that implements the getView() method.

There are literally hundreds of tutorials on how to do this, but this one seems to be more detailed.
