activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"

    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"

    android:paddingRight="@dimen/activity_horizontal_margin"

    android:paddingTop="@dimen/activity_vertical_margin"

    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

    <GridView

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:id="@+id/gridView"

        android:numColumns="2"

        android:horizontalSpacing="1dp"

        android:verticalSpacing="5dp"

        android:layout_alignParentLeft="true"

        android:layout_alignParentStart="true"

        android:layout_marginTop="146dp" />

</RelativeLayout>

然后，我们来设置数据源（用来填充GridView的）。首先在values下创建一个xml文件，命名为array.xml,内容例如以下:

<?

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

>

<resources>

    <!-- 热门城市 -->

    <string-array name="hot_city">

        <item>北京</item>

        <item>上海</item>

        <item>广州</item>

        <item>深圳</item>

        <item>杭州</item>

        <item>成都</item>

    </string-array>

</resources>

MainActivity.java:

package com.example.gridview;

import android.support.v7.app.ActionBarActivity;

import android.os.Bundle;

import android.view.Menu;

import android.view.MenuItem;

import android.widget.ArrayAdapter;

import android.widget.GridView;

public class MainActivity extends ActionBarActivity {

    private ArrayAdapter<String> mAdapterHot;

    private GridView gv;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        gv = (GridView) findViewById(R.id.gridView);

        //第一个參数是context,第二个參数是GridView中item的布局文件，第三个參数是数据源

        mAdapterHot = new ArrayAdapter<String>(MainActivity.this, R.layout.text_item, getResources().getStringArray(R.array.hot_city));

        gv.setAdapter(mAdapterHot);

    }

}

text_item.xml:

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

>

<TextView

    xmlns:android="http://schemas.android.com/apk/res/android"

    android:id="@+id/myCheckedTextView1"

    android:layout_width="80dp"

    android:layout_height="35dp"

    android:textColor="#a99a8a"

    android:textSize="16dp"

    android:text="aaaaa"

    android:background="#88aa99"

    android:gravity="center"

    android:paddingLeft="6dip"

    />
