1）main.xml -- 布局文件

< xml version="1.0" encoding="utf-8" >
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:alwaysDrawnWithCache="true"
android:orientation="vertical"
android:scrollbarAlwaysDrawHorizontalTrack="true"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbars="horizontal|vertical" >

android:layout_width="wrap_content"
android:layout_height="fill_parent" >

android:id="@+id/data_gridview"
android:layout_width="1395dip"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:background="#ff0000"
android:columnWidth="31dip"
android:gravity="center"
android:numColumns="45"
android:scrollbarAlwaysDrawHorizontalTrack="true"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbars="horizontal|vertical"
android:horizontalSpacing="1dip"
android:verticalSpacing="1dip" />

2) 每个gridcell对应的layout文件 --

imagecell.xml

< xml version="1.0" encoding="utf-8" >
android:layout_width="match_parent"
android:layout_height="match_parent" >

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true" >

3)Activity的代码 -- 这里为了提高性能，实现了重用View的机制

package com.xxxx.ui

import xxxx.xxxx

public class GridViewTestActivity extends Activity {

private int disp_rows = 20; //显示多少行
private final static int COLUMN_CNT = 45; //显示多少列，这个要和layout文件里面对应起来

private GridView dataGridView;

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

dataGridView = (GridView) findViewById(R.id.data_gridview);
dataGridView.setNumColumns(COLUMN_CNT);//一共45列

dataGridView.setAdapter(new CellAdapter(getApplicationContext（）));
dataGridView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView< > parent, View v, int position, long id) {
Toast.makeText(GridViewTestActivity.this, "" + position, Toast.LENGTH_SHORT).show();
}
});

} //end onCreate

class CellAdapter extends BaseAdapter {
private Context mContext;
private LayoutInflater mInflater;

public CellAdapter(Context c) {
mContext = c;
mInflater = LayoutInflater.from(c);
}

public int getCount() {
return (disp_rows * COLUMN_CNT); //行数x列数为一共要显示多少个格子
}

public Object getItem(int position) {
return null; //do nothing now
}

public long getItemId(int position) {
return 0;
}
