android 最簡單的九宮格實作

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 檔案裡面放2個。一個圖檔和一個文字：

主檔案直接放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>

這樣就完成了。

當然，如果簡單一點的話直接适配比較好！

代碼以下：

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;

public Object getItem(int position) {

return position;

public long getItemId(int position) {

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;
