android 最简单的九宫格实现

public class GridViewFunction extends Activity {

private GridView _gridview;

private List<Map<String ,Object>> list;

_gridview=(GridView) findViewById(R.id.gridView1);

list=new ArrayList<Map<String,Object>>();

for (int i = 0; i < 9; i++) {

Map<String,Object> map=new HashMap<String, Object>();

map.put("img",R.drawable.icon);

map.put("text",i+"item");


list.add(map);

}

SimpleAdapter simple=new SimpleAdapter(getApplicationContext(), list, R.layout.gridview_item,new String[]
{"img","text"},new int[]{R.id.log_item_image,R.id.log_item_text}); _gridview.setAdapter(new GridViewAdapter(this));

}

R.layout.gridview_item 文件里面放2个。一个图片和一个文字：

主文件直接放GIRDVIEW控件。

<GridView android:id="@+id/gridView1"

android:layout_width="fill_parent"

android:numColumns="auto_fit"

android:stretchMode="columnWidth"

android:columnWidth="90dp"

android:gravity="center"


android:layout_height="fill_parent">

</GridView>

这样就完成了。

当然，如果简单一点的话直接适配比较好！

代码以下：

class GridViewAdapter extends BaseAdapter{

private Context ct;
public GridViewAdapter(Context ct){
this.ct=ct;
}

private int [] img={R.drawable.imagebutton1,R.drawable.imagebutton2,R.drawable.imagebutton3,
R.drawable.imagebutton4,R.drawable.imagebutton5,R.drawable.imagebutton6,R.drawable.imagebutton7,R.drawable.imagebutton8,R.drawable.imagebutton9};

private String [] text= {
"A","B","C","D"
,"E","F","G","H"
,"I"
};

@Override
public int getCount() {
// TODO Auto-generated method stub
return text.length;
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
WrapperImgText wrapper;
if(convertView==null){
wrapper=new WrapperImgText();
LayoutInflater layout=LayoutInflater.from(ct);

convertView=layout.inflate(R.layout.gridview_item,null);
convertView.setTag(wrapper);
convertView.setPadding(15, 15, 15, 15);

}else{
wrapper=(WrapperImgText) convertView.getTag();
}
wrapper.image=(ImageView) convertView.findViewById(R.id.log_item_image);
wrapper.tv=(TextView) convertView.findViewById(R.id.log_item_text);

wrapper.image.setBackgroundResource(img[position]);
wrapper.tv.setText(text[position]);

return convertView;
}

class WrapperImgText{
ImageView image;
TextView tv;
}

}
