如何处理listview中的每个按钮的点击？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);
}
});我如何管理列表视图中每一项的按钮点击?我尝试了很多方法..如何解决此问题。？请任何人帮帮我。

尝尝这个,
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 ;
}它可能会帮助你..。

在listview适配器中，像正常一样初始化按钮并设置onclicklistener。
看一下这个，所以回答更多信息：Android: ListView elements with multiple clickable buttons

请参阅以下链接

对于你的问题，Athul (https://stackoverflow.com/users/6201929/athul)的回答是最好的。
否则，如果您需要活动上的事件操作。
请参阅以下内容
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
将创建onClickButtonInItem侦听器。你可以在这个位置上做任何事。
