gridview_item.xml

这个是一个item的单元格样式的，有图片和文字

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingLeft="10dp" android:scaleType="fitCenter" android:src="@drawable/ic_launcher" /> <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="TextView" /></LinearLayout>

MainActivity.java

import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;import android.app.Activity;import android.os.Bundle;import android.widget.GridView;public class MainActivity extends Activity { private GridView gridView; private GridViewAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // 设置适配器的图片资源 int[] imageId = new int[] { R.drawable.chat_tool_camera, R.drawable.chat_tool_location, R.drawable.chat_tool_paint, R.drawable.chat_tool_video, R.drawable.chat_tool_voice, R.drawable.chat_tool_camera, R.drawable.chat_tool_location, R.drawable.chat_tool_paint, R.drawable.chat_tool_video, R.drawable.chat_tool_voice, R.drawable.chat_tool_camera, R.drawable.chat_tool_location, R.drawable.chat_tool_paint, R.drawable.chat_tool_video, R.drawable.chat_tool_voice, R.drawable.chat_tool_camera, R.drawable.chat_tool_location, R.drawable.chat_tool_paint, R.drawable.chat_tool_video, R.drawable.chat_tool_voice }; // 设置标题 String[] title = new String[] { "相机", "定位", "画笔", "视频", "声音", "相机", "定位", "画笔", "视频", "声音", "相机", "定位", "画笔", "视频", "声音", "相机", "定位", "画笔", "视频", "声音" }; List<Map<String, Object>> listitem = new ArrayList<Map<String, Object>>(); // 将上述资源转化为list集合 for (int i = 0; i < title.length; i++) { Map<String, Object> map = new HashMap<String, Object>(); map.put("image", imageId[i]); map.put("title", title[i]); listitem.add(map); } adapter = new GridViewAdapter(MainActivity.this, listitem); gridView = (GridView) this.findViewById(R.id.gridView); gridView.setAdapter(adapter); }}

GridViewAdapter.java

这个是适配器

import java.util.List;import java.util.Map;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;public class GridViewAdapter extends BaseAdapter { private Context context; private List<Map<String, Object>> listitem; public GridViewAdapter(Context context,List<Map<String, Object>> listitem) { this.context = context; this.listitem = listitem; } @Override public int getCount() { return listitem.size(); } @Override public Object getItem(int position) { return listitem.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = LayoutInflater.from(context).inflate(R.layout.gridview_item, null); } ImageView imageView = (ImageView) convertView.findViewById(R.id.image); TextView textView = (TextView) convertView.findViewById(R.id.textView); Map<String, Object> map = listitem.get(position); imageView.setImageResource((Integer) map.get("image")); textView.setText(map.get("title") + ""); return convertView; }}

效果图如下：
