Custom List View with Search Box

To generate Custom List View in our application,we need to create List View in main. XML,

The main.XML file is look like this,


<?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"
    >
    <EditText  
       android:id="@+id/search" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       android:hint="Search"
    />
    <ListView 
         android:id="@+id/custom" 
         android:layout_width="fill_parent" 
         android:layout_height="wrap_content">
   </ListView>
</LinearLayout>



Here I used one Edit text in the top of the List View,the Edit Text will show when user clicked search menu item from menu,

Here is my source code of custom List View.,

search_box.setVisibility(View.GONE);

int length = search_box.getText().length();
searched_list.clear();


for (int i = 0; i < COUNTRIES.length; i++) {
if (length <= COUNTRIES[i].length()) {
if (search_box.getText().toString().equalsIgnoreCase((String)COUNTRIES[i].subSequence(0,
length))) {
searched_list.add(COUNTRIES[i].toString());

}
});
}


@Override
public boolean onCreateOptionsMenu(final Menu menu) {
// call the base class to include system menus
super.onCreateOptionsMenu(menu);

// Group 1
final int group1 = 1;
final MenuItem infoBtn = menu.add(group1, 1, 1, "Search").setIcon(R.drawable.icon);


// Group 2
final int group2 = 2;
final MenuItem appSettings = menu.add(group2, 2, 2, "Cancel").setIcon(R.drawable.icon);
return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 1: {
search_box.setVisibility(View.VISIBLE);
break;
}
case 2: {
search_box.setVisibility(View.GONE);
break;
}
}
return false;
}


@Override
public void onBackPressed() {                  //It will work only on v2.2 and above 
search_box.setVisibility(View.GONE);
}
}




And here is the Output:
