How to create a scrolling ListView in android?
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"?> <relativeLayout android: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
}
});
}
}
