ListView with Context menu in android

ListView with Context menu in android

1,Define the xml file:-

   <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:orientation="vertical"
  >
  <ListView
    android:id="@+id/list"
    android:layout_width="fill_parent"
    android:layout_height="0px"
    android:layout_weight="1"
    />
   </LinearLayout>

2, Define the layout for items in the ListView (listitem.xml):

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

       <TextView
       xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="fill_parent" android:layout_height="wrap_content"
       android:textSize="35dip"
       android:padding="8dip"
       android:textColor="#990000"
        />
3,  Define the array in string.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, Listview_contextmenuActivity!</string>
    <string name="app_name">Listview_contextmenu</string>
    <string-array name="Countries"><item>jisho</item>
    <item>aju</item>
    <item >gino</item>
    <item >binish</item>
    <item>alex</item>
    <item >vishnu</item>
    <item >arun</item>
    </string-array>
 </resources>

4, Retrieve the array element from strings.xml: and Sort the string;

        Resources res = getResources();
        Countries = getResources().getStringArray(R.array.Countries);

         Arrays.sort(Countries);

5, Define the Array adapter and set the register for Context menu.

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.listitem,Countries);
        list.setAdapter(adapter);
        registerForContextMenu(list);


6,  Override the Context menu:-

     @Override
public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo)
{
      if (v.getId()==R.id.list)
{
        AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)menuInfo;
        menu.setHeaderTitle(Countries[info.position]);
        String[ ] menuItems = getResources().getStringArray(R.array.Countries);
        for (int i = 0; i<menuItems.length; i++)
 {
          menu.add(Menu.NONE, i, i, menuItems[i]);
  }
  }
  }
