基本按照老師步驟編寫，卻運行不了。求高人指點?。。?/h1>

public class MainActivity extends Activity {

GridView gv;

SimpleAdapter sa;

List<HashMap<String, Object>> list;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

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

//創建數據源

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

//適配器

sa=new SimpleAdapter(this, getData(), R.layout.main,

new String[]{"imageView1","textView1"}, new int[]{R.id.imageView1,R.id.textView1} );

//添加適配器

gv.setAdapter(sa);

}

//給list賦值

public List<HashMap<String, Object>> getData(){

for(int i=0;i<7;i++){

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

map.put("imageView1", R.drawable.ic_launcher);

map.put("textView1", "hao"+i);

}

return list;

}

}
