java - 如何在此代码中使用 .trim() 方法？

Question

当我从数据库中获取数据时，由于数据格式不正确，出现了很多空格。如何在此代码中使用 .trim() 方法。

@Override
    public void onStart() {
        super.onStart();
        groupDeals.addSnapshotListener(new EventListener<DocumentSnapshot>() {
                                           @Override
                                           public void onEvent(@javax.annotation.Nullable DocumentSnapshot documentSnapshot, @javax.annotation.Nullable FirebaseFirestoreException e) {
                                               if (e != null) {
                                                   return;
                                               }
                                               if (documentSnapshot.exists()) {

                                                   String grpDealsDetails = documentSnapshot.getString(GROUP_DEALS_KEY_DEALS);

                                                   if (TextUtils.isEmpty(grpDealsDetails)) {
                                                       tv_groupDeals.setText("Not Available");
                                                   } else {
                                                       Spanned descripti;

                                                       if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                                                           descripti = Html.fromHtml(grpDealsDetails, Html.FROM_HTML_MODE_LEGACY);
                                                       } else {
                                                           descripti = Html.fromHtml(grpDealsDetails);
                                                       }
                                                       tv_groupDeals.setText(descripti);
                                                       tv_groupDeals.setMovementMethod(LinkMovementMethod.getInstance());
                                                   }

                                               }
                                           }
                                       }
        );
    }

Answer 1

设置之前tv_groupDeals.setText(descripti);
您可以添加 descripti= descripti.trim();
