在視圖類android.widget.ImageView上定義的android：onClick屬性的父級或祖先上下文中找不到方法

Question

我基本上只是在XML中針對特定ImageView的android：onClick函數中調用此函數： android:onClick="SendGetStartedNotification" 。 但是因為我的函數有兩個參數，所以我得到了這個錯誤， Method has incorrect signature 。 它希望我刪除ParseUser類。

public void SendGetStartedNotification(View view, ParseUser user) {

    // initiate installation query
    ParseQuery<ParseInstallation> query  = ParseInstallation.getQuery();
    query.whereEqualTo("userId", user.getUserObject());

    // send push notification
    ParsePush push = new ParsePush();
    push.setQuery(query);
    push.setMessage(ParseUser.getCurrentUser().getUsername() + " " + "thinks you should create something!");
    push.sendInBackground();

    // send notification to NotificationsActivity
    ParseObject notification = createGetStartedMessage(view, user);
    send(notification);
}

問題是我的錯誤信息：

我有什么選擇？ 以編程方式設置onClick偵聽器似乎也不起作用。 我該怎么辦？

更新：我正在使用AsyncTask將用戶信息帶入我的班級。

private class GetParseUserInformationTask extends AsyncTask<Void, Design, ParseUser> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            mProgressDialog = new ProgressDialog(GalleryActivity.this);
            // Set progressdialog message
            mProgressDialog.setMessage("Loading Designs...");
            mProgressDialog.setIndeterminate(false);
            // Show progressdialog
            mProgressDialog.show();

        }

        @Override
        protected ParseUser doInBackground(Void... params) {

            ParseUser parseUser = null;

            // gather User information and then fetch the designs for them
            try {
                parseUser = ParseHelper.GetUserInformation(userObjectId);
            } catch (ParseException e) {
                e.printStackTrace();
            }

            return parseUser;
        }

        @Override
        protected void onPostExecute(ParseUser user) {

            if(user == null) {
                //todo: some error message
                return;
            }

            ((TextView)findViewById(R.id.fullName)).setText(user.getName());
            ((TextView)findViewById(R.id.bio)).setText(user.getBio());
            ((TextView)findViewById(R.id.websiteLink)).setText(user.getWebsiteLink());
            ((TextView)findViewById(R.id.username)).setText(user.getUsername());
            ((TextView)findViewById(R.id.saves_number)).setText(user.getFeedDesignSaves().toString());
            ((TextView)findViewById(R.id.designs_number)).setText(String.valueOf(ParseHelper.GetUserDesignsCount(user.getUserObject())));
            ((ImageView)findViewById(R.id.profile_picture)).setImageDrawable(Drawable.createFromPath(user.getProfilePictureURL()));

            // asynchronously display the profile picture downloaded from parse
            if(user.getProfilePictureURL() != null) {
                profilePictureImageLoader.DisplayImage(user.getProfilePictureURL(), ((ImageView) findViewById(R.id.profile_picture)), null);
            }

            new GetParseUserDesignsTask().execute(user);

            mProgressDialog.dismiss();
        }
    }

開單擊按鈕上的偵聽器。

 imageView.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View view) {
                        // TODO Auto-generated method stub
SendGetStartedNotification(ParseUser user);

                    }
                } );

使您的方法像這樣：

public void SendGetStartedNotification(ParseUser user) {

    // initiate installation query
    ParseQuery<ParseInstallation> query  = ParseInstallation.getQuery();
    query.whereEqualTo("userId", user.getUserObject());

    // send push notification
    ParsePush push = new ParsePush();
    push.setQuery(query);
    push.setMessage(ParseUser.getCurrentUser().getUsername() + " " + "thinks you should create something!");
    push.sendInBackground();

    // send notification to NotificationsActivity
    ParseObject notification = createGetStartedMessage(view, user);
    send(notification);
}
