Question

目前，我的listView位于片段内。但是，只要点击它们，我视图中的按钮就无法接收点击事件。

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!");
        }
    });
}

}

以下是每个项目的xml：

Answer 1

将此行添加到列表项xml文件中。

android:descendantFocusability="blocksDescendants"

Answer 2

如果你在newView方法中设置clicklistener，它应该工作。我通常使用getView（）来获取此方法，并且从未出现过问题。

@覆盖 public View getView（Context context，View View，ViewGroup parent）{

ViewHolder holder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
         View = inflater.inflate(R.layout.your_layout_file_id, 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);

holder.cancel.setOnClickListener（new OnClickListener（）{

    @Override
    public void onClick(View arg0) {

          Log.i("cancel", "cancel clicked!");

    }
});

return view;

}

ListView中的按钮无法接收OnClick？
