【问题描述】：
目前，我的 listView 位于片段内。但是，每当我点击它们时，视图中的按钮都无法接收 on click 事件。
我不知道该怎么做。
这是我的代码：
public class ViewInvitationsCursorAdapter extends CursorAdapter {
private Activity activity;
private int layout;
private Cursor cr;
private final LayoutInflater inflater;
private Fragment f;
private boolean displayAcceptDeny;
public ViewInvitationsCursorAdapter(Activity activity, Fragment f,
int layout, Cursor c, boolean displayAcceptDeny) {
super(activity, c);
this.layout = layout;
this.activity = activity;
this.inflater = LayoutInflater.from(activity);
this.cr = c;
this.f = f;
this.displayAcceptDeny = displayAcceptDeny;
}
public static class ViewHolder {
public TextView sender;
public TextView sender_email;
public TextView author_role;
public Button deny;
public Button accept;
public Button cancel;
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
ViewHolder holder = new ViewHolder();
View view = inflater.inflate(layout, parent, false);
holder.sender = (TextView) view.findViewById(R.id.connection_sender);
holder.sender_email = (TextView) view
.findViewById(R.id.connection_sender_email);
holder.author_role = (TextView) view.findViewById(R.id.connection_role);
holder.accept = (Button) view.findViewById(R.id.connection_allow);
holder.deny = (Button) view.findViewById(R.id.connection_deny);
holder.cancel = (Button) view.findViewById(R.id.connection_cancel);
view.setTag(holder);
return view;
}
@Override
public void bindView(View view, Context context, final Cursor cursor) {
// .bindView(view, context, cursor);
final ViewHolder holder = (ViewHolder) view.getTag();
int sender_index = cursor
.getColumnIndexOrThrow(FamilyDBHelper.COLUMN_SENDER_BY_NAME);
int sender_email_index = cursor
.getColumnIndexOrThrow(FamilyDBHelper.COLUMN_SENDER_BY_EMAIL);
String senderString = cursor.getString(sender_email_index);
int author_role_name = cursor
.getColumnIndexOrThrow(FamilyDBHelper.COLUMN_RELATIONTYPE_NAME);
int message_index = cursor
.getColumnIndexOrThrow(FamilyDBHelper.COLUMN_MESSAGE);
holder.sender.setText(cursor.getString(sender_index));
holder.author_role.setText(cursor.getString(author_role_name));
holder.sender_email.setText(cursor.getString(sender_email_index));
holder.cancel.setVisibility(View.VISIBLE);
// setUpCancel(view, cursor);
holder.cancel.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Log.i("cancel", "cancel clicked!");
}
});
}
protected void setUpAcceptDeny(View view, final Cursor cursor) {
final ViewHolder holder = (ViewHolder) view.getTag();
holder.accept.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Log.i("accept", "accept clicked!");
}
});
holder.deny.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
Log.i("deny", "deny clicked!");
}
});
}
}
这是每个项目的 xml：

【问题讨论】：
-
@Faytll 我没有看到调用 setUpAcceptDeny
-
@Maddy：我减少了代码以便尝试找出问题所在。
-
@Krylez：这些解决方案都不适合我。如果我的列表视图在片段内，它会改变吗？
