ListView is like a tableView in iPhone or iOS . In this example i will show you how to add a String Array in to the ListView and also make the listView Scrollable.
First the xml file . Here the line
android:scrollbars=”vertical”
will make the scrolling vertically
<?xml version="1.0" encoding="utf-8"?><relativeLayoutandroid:id="@+id/widget32"android:layout_width="fill_parent"android:layout_height="fill_parent"xmlns:android="http://schemas.android.com/apk/res/android"> <listView android:id="@+id/listview" android:scrollbars="vertical" android:layout_width="fill_parent" android:layout_height="200dip" android:layout_gravity="fill_vertical" android:layout_alignParentTop="true" > </listView></relativeLayout> |
Now the java file
package com.Ch.Example.pack;import java.util.ArrayList;import java.util.List;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.ArrayAdapter;import android.widget.ListView;import android.widget.AdapterView.OnItemClickListener;public class Example extends Activity{ /** Called when the activity is first created. */ ListView list; private List<string> List_file; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); List_file =new ArrayList<string>(); list = (ListView)findViewById(R.id.listview); CreateListView(); } private void CreateListView() { List_file.add("Coderzheaven"); List_file.add("Google"); List_file.add("Android"); List_file.add("iPhone"); List_file.add("Apple"); //Create an adapter for the listView and add the ArrayList to the adapter. list.setAdapter(new ArrayAdapter<string>(Example.this, android.R.layout.simple_list_item_1,List_file)); list.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) { //args2 is the listViews Selected index } }); }} |
