View Code

注意：必须在TabHost中写

菜单

重写Activity中OnCreateOptionsMenu
public boolean onCreateOptionsMenu(Menu menu) {
//分组，菜单选项id，菜单编号，菜单标题
menu.add(Menu.NONE,0,0,"保存");
menu.add(Menu.NONE,1,0,"删除");
//子菜单
SubMenu help = menu.addSubMenu("帮助");
help.add("保存介绍");
help.add("出错方案");
return super.onCreateOptionsMenu(menu);
}
上下级菜单
TextView tv = (TextView)findViewById(R.id.tvv);
  registerForContextMenu(tv);
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
  menu.add("保存");
  menu.add("删除");
  menu.add("退出");
  super.onCreateContextMenu(menu, v, menuInfo);
}
（第二种方法在onCreateContextMenu修改）
MenuInflater fInflater = getMenuInflater();
  fInflater.inflate(R.menu.main, menu);
  menu.setHeaderIcon(R.drawable.icon);
  menu.setHeaderTitle("帮助");
Gallery
int [] imgs = {R.drawable.icon,R.drawable.wo,R.drawable.icon,R.drawable.wo};
Gallery gallery= (Gallery)findViewById(R.id.gallery);
List<Map<String,Integer>> data = new ArrayList<Map<String,Integer>>();
for(int i=0;i<imgs.length;i++){
int img = imgs[i];
Map<String,Integer> map = new HashMap<String, Integer>();
map.put("img",img);
data.add(map);
}
SimpleAdapter dAdapter = new SimpleAdapter(this,data,R.layout.xiala1
,new String[]{"img"}
,new int[]{R.id.IMAGE});
gallery.setAdapter(dAdapter);
