Single Selection ListView in android

Hello all…..

In today’s post I will show you how to create a single selection list in android.

Here is the main.xml

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

<?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"     >      <ListView             android:id="@android:id/list"             android:cacheColorHint="#00000000"             android:scrollbars="none"             android:fadingEdge="vertical"             android:soundEffectsEnabled="true"             android:dividerHeight="1px"             android:padding="5dip"             android:smoothScrollbar="true"             android:layout_width="fill_parent"             android:layout_height="wrap_content"             android:drawSelectorOnTop="false"             android:layout_marginLeft="10dip"             android:layout_marginRight="10dip"             android:layout_marginBottom="10dip"             android:layout_weight="1"/>   </LinearLayout>

Now this line in the java file creates the single choice.

setListAdapter(new ArrayAdapter(this,
android.R.layout.simple_list_item_single_choice,
android.R.id.text1, names));

Now this is the full java code

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

package com.coderzheaven.pack;   import android.app.ListActivity; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.ListView;   public class ListView1 extends ListActivity {     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);           String[] names = new String[] { "Android", "Windows7", "Symbian", "iPhone",                 "Android", "Windows7", "Symbian", "iPhone",                 "Android", "Windows7", "Symbian", "iPhone" };         setListAdapter(new ArrayAdapter<String>(this,                        android.R.layout.simple_list_item_single_choice,                        android.R.id.text1, names));         ListView listView = getListView();         listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);       } }
