A simple ListView using android.R.layout.simple_list_item_1 layout

It's a very simple and standard example of ListView, using the built-in layout android.R.layout.simple_list_item_1 layout.

package com.AndroidListView;



import android.app.Activity;

import android.os.Bundle;

import android.widget.ArrayAdapter;

import android.widget.ListView;



public class AndroidListViewActivity extends Activity {

	

	ListView myList;

	

	String[] listContent = {

			"January",

			"February",

			"March",

			"April",

			"May",

			"June",

			"July",

			"August",

			"September",

			"October",

			"November",

			"December"

	};

	

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

   super.onCreate(savedInstanceState);

   setContentView(R.layout.main);

   myList = (ListView)findViewById(R.id.list);



   ArrayAdapter<String> adapter

   = new ArrayAdapter<String>(this,

   		android.R.layout.simple_list_item_1,

   		listContent);

   myList.setAdapter(adapter);



}

}

<?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:layout_width="fill_parent"

android:layout_height="wrap_content"

android:text="@string/hello"

/>

<ListView

android:id="@+id/list"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

/>

</LinearLayout>

But...what's android.R.layout.simple_list_item_1. You can check it in <android-sdk>/platforms/<android-version>/data/res/layout/simple_list_item_1.xml. Such that you can copy and modify it for your own.

For example, the content of android-sdk-linux_x86/platforms/android-7/data/res/layout/layout/simple_list_item_1.xml is:

<?xml version="1.0" encoding="utf-8"?>
