如何处理列表视图中的每个按钮单击。？ 活动类

 String[] from = new String[]{DBHelper.ID, DBHelper.FNAME, DBHelper.LNAME, DBHelper.ADDRESS, DBHelper.REGID};
int[] to = new int[]{R.id.id,R.id.fname,R.id.lname,R.id.address,R.id.regid};
  adapter = new SimpleCursorAdapter(this, R.layout.list, cursor, from, to, 0);
  listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
        //listview click event handling
            id = (TextView) arg1.findViewById(R.id.id);
            int id_To_Search = Integer.valueOf(id.getText().toString());

            Bundle dataBundle = new Bundle();
            dataBundle.putInt("_id", id_To_Search);

            Intent intent = new Intent(getApplicationContext(), AddPatient.class);

            intent.putExtras(dataBundle);
            startActivity(intent);
        }
    });

如何管理列表视图中每个项目的按钮单击。我尝试了很多方法。我该如何解决这个问题。？请任何人帮助我...

Answer 1

试试这个，

public View getView(final int position, View convertView,ViewGroup parent) 
{
   if(convertView == null)
   {
        LayoutInflater inflater = getLayoutInflater();
        convertView  = (LinearLayout)inflater.inflate(R.layout.YOUR_LAYOUT, null);
   }

   Button Button1= (Button)  convertView  .findViewById(R.id.BUTTON1_ID);

   Button1.setOnClickListener(new OnClickListener() 
   { 
       @Override
       public void onClick(View v) 
       {
           // Your code that you want to execute on this button click
       }

   });


   return convertView ;
}

在您的列表视图适配器中，正常初始化按钮并设置 onclicklistener。

Answer 3

参考以下链接

http://androidforbeginners.blogspot.in/2010/03/clicking-buttons-in-listview-row.html

Athul (https://stackoverflow.com/users/6201929/athul) 的答案最适合您的问题。

否则，如果您需要对活动进行事件操作。

参考下面

public class UsersAdapter extends BaseAdapter {

    Context context;
    OnClickButtonOnList onClickButtonOnList;
    public UsersAdapter(Context context, ArrayList<User> users, OnClickButtonOnList onClickButtonOnList) {
       this.context = context;
       this.users = users;
       this.onClickButtonOnList = onClickButtonOnList;
    }

    public View getView(final int position, View convertView,ViewGroup parent) 
    {
   if(convertView == null)
   {
        LayoutInflater inflater = getLayoutInflater();
        convertView  = (LinearLayout)inflater.inflate(R.layout.YOUR_LAYOUT, null);
   }

   Button Button1= (Button)  convertView  .findViewById(R.id.BUTTON1_ID);

   Button1.setOnClickListener(new OnClickListener() 
   { 
       @Override
       public void onClick(View v) 
       {
           onClickButtonOnList.onClickButtonInItem(position);
       }

   });


   return convertView ;
    }

   public interface OnClickButtonOnList {
        public void onClickButtonInItem(int position);
   }
}

活动

UsersAdapter arrayadapter = new UsersAdapter(this, users, this);
listview.setAdapter(arrayadapter);

按 Alt + Enter

onClickButtonInItem 监听器将被创建。你可以对这个职位做任何事情。
