package com.example.androidtest;import android.os.Bundle;import android.app.Activity;import android.database.Cursor;import android.provider.Contacts.People;import android.widget.GridView;import android.widget.SimpleCursorAdapter;public class MainActivity extends Activity  {public void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);GridView gv = (GridView)findViewById(R.id.gridview);Cursor c = managedQuery(People.CONTENT_URI, null, null, null, People.NAME);String[] cols = new String[]{People.NAME};int[] views = new int[]{android.R.id.text1};SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, c, cols, views);gv.setAdapter(adapter);}}

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?><!-- This file is at /res/layout/gridview.xml --><GridView xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/gridview"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:padding="10px"    android:verticalSpacing="10px"    android:horizontalSpacing="10px"    android:numColumns="auto_fit"    android:columnWidth="100px"    android:stretchMode="columnWidth"    android:gravity="center"    />
