Button随机想要的个数

Question

private void Update()
{
if (mTimer != null)
{
mTimer.cancel();
}
ArrayList<HashMap<String, Object>> uList=new ArrayList<HashMap<String, Object>>();
System.out.println("11+++       ----------------------");
HashMap<String, Object> map1 =new HashMap<String, Object>();

UserFormDAO userFormDAO = new UserFormDAO(this);
UserForm userForm=new UserForm();
mProgressDialog.dismiss(); 
//txt = (TextView) findViewById(R.id.EditTextReception);
System.out.println("22+++       ----------------------");

for (int i = 0; i < tags.size(); i++)
{

System.out.println("3333+++       ----------------------");
int yuan =Integer.valueOf(tags.get(i));
userForm=userFormDAO.find(yuan);

if((userForm=userFormDAO.find(yuan))!=null){
//txt.append(userForm.getUid()+" "+userForm.getUname()+" "+userForm.getUsex()+" "+userForm.getUage()+" "+userForm.getUmedicine()+" "+userForm.getUtime()+"\n");
//txt.append(tags.get(i) + "   ");
System.out.println(" ----------111--------正确");
map1.put("buttonxianshi", tags.get(i));
System.out.println(" ----------121--------正确");
uList.add(map1);

System.out.println(uList.size()+" ----------222--------正确");
System.out.println(uList.get(1)+" ----------222--------正确");
}else{
System.out.println("444+++       ----------------------");
}
}
SimpleAdapter listAdapter =new SimpleAdapter(this,uList,R.layout.buttonfor,new String[]{"buttonxianshi"},new int[]{R.id.buttonxianshi});  
listView.setAdapter(listAdapter);  

 ReceiveData = false;
}
越界了   后来发现  buttonxianshi    这个名字不知道怎么让他在xml 随机生成和map1.put里的名称匹配 。有没有大虾 给个例子 或者   提出个解决方案的  有空帮帮看下呐！

Answer 1

R.layout.buttonfor里有没有id为buttonxianshi的控件，如果没有，加一个就可以了

Answer 2

private void Update()
{   
if (mTimer != null)
{
mTimer.cancel();
}

gridView = (GridView)findViewById(R.id.GridView_playbar);
gridView.setSelector(R.drawable.icon);
UserFormDAO userFormDAO = new UserFormDAO(this);
UserForm userForm=new UserForm();
mProgressDialog.dismiss(); 

for (int i = 0; i < tags.size(); i++)
{

HashMap<String, Object> map =new HashMap<String, Object>();
int yuan =Integer.valueOf(tags.get(i));
userForm=userFormDAO.find(yuan);

if((userForm=userFormDAO.find(yuan))!=null){
String mat=tags.get(i);
map.put("buttonxianshi",tags.get(i));
uList.add(map);
}
     }
SimpleAdapter listAdapter =new SimpleAdapter(ConsoleActivity.this,uList,R.layout.buttonfor,new String[]{"buttonxianshi"},new int[]{R.id.buttonxianshi});  

gridView.setAdapter(listAdapter);
ReceiveData = false;

}现在是类转换异常了 

Answer 3

ArrayList<HashMap<String, Object>> uList=new ArrayList<HashMap<String, Object>>();
private void Update()
{   
if (mTimer != null)
{
mTimer.cancel();
}

gridView = (GridView)findViewById(R.id.GridView_playbar);
UserFormDAO userFormDAO = new UserFormDAO(this);
UserForm userForm=new UserForm();
mProgressDialog.dismiss(); 
//txt = (TextView) findViewById(R.id.EditTextReception);

for (int i = 0; i < tags.size(); i++)
{

HashMap<String, Object> map =new HashMap<String, Object>();
int yuan =Integer.valueOf(tags.get(i));
userForm=userFormDAO.find(yuan);

if((userForm=userFormDAO.find(yuan))!=null){
//txt.append(userForm.getUid()+" "+userForm.getUname()+" "+userForm.getUsex()+" "+userForm.getUage()+" "+userForm.getUmedicine()+" "+userForm.getUtime()+"\n");
//txt.append(tags.get(i) + "   ");
String mat=tags.get(i);
map.put("buttonxianshi",tags.get(i));
uList.add(map);
}else{
}
}
SimpleAdapter listAdapter =new SimpleAdapter(ConsoleActivity.this,uList,R.layout.buttonfor,new String[]{"buttonxianshi"},new int[]{R.id.buttonxianshi});  
gridView.setAdapter(listAdapter);
ReceiveData = false;
}
解决后的
