ArrayAdapter sample program in Android
By: Ashley
This sample android program shows you how to use ArrayAdapter in Android. In this program a list
is shown. When you click on the list, the selected item is shown on the text
view. You can use this ArrayAdapter widget and the
onListItemClick() method to determine the selected index and process
accordingly.
The
ArrayAdapterDemo
.java file is as follows:
package com.javasamples;
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class ArrayAdapterDemo extends ListActivity {
TextView selection;
String[] items = { "this", "is", "a",
"really",
"silly", "list" };
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setListAdapter(new ArrayAdapter<String>(
this,
android.R.layout.simple_expandable_list_item_1,
items));
selection=(TextView)findViewById(R.id.selection);
}
@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
String text = " position:" + position + " " +
items[position];
selection.setText(text);
}
}
The output of this program will be as shown in the android emulator below.
The main.xml file in your res/layout folder is as follows:
<?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" >
<TextView
android:id="@+id/selection"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#ff0000cc"
android:textStyle="bold"/>
<ListView
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"
android:choiceMode="multipleChoice"
/>
</LinearLayout>
