問題描述

對不起，如果標題有點模糊.

Sorry if the title was a bit vague.

我正在 Freelancer 上開發一個應用程序，除了一些測試后客戶的投訴外，我幾乎完成了它.

I'm developing an app on Freelancer and I almost have it finished except for a complaint from the customer after some testing.

如果有意義的話，我會使用 PopupWindow 代替對話框來編輯上下文設置.我不想太具體而冒著泄露應用概念的風險，我相信客戶不會對此感到太高興.

I use a PopupWindow in place of a dialog to edit contextual settings, if that makes any sense. I don't want to be too specific and risk giving the app concept away, which I'm sure the customer wouldn't be too pleased about.

PopupWindow 被賦予了一個從 XML 擴展而來的布局的內容視圖.在該布局中有幾個 EditText 小部件.問題是那些 EditTexts 不會在長按時觸發默認的上下文對話框，該對話框提供文本/IME 選擇和剪切/復制/粘貼選項.

The PopupWindow is given a Content View of a layout inflated from XML. In that layout are several EditText widgets. The issue is that those EditTexts will not trigger the default contextual dialog on long press that presents options for text/IME selection, and cut/copy/paste.

我看到一個類似的問題試圖獲取 TouchTrigger 或其他東西，但如果沒有 setBackgroundDrawable()，它就無法工作，我已經嘗試使用簡單的 new ColorDrawable().還是不行.

I saw a similar question trying to get the TouchTrigger or something and it not working without setBackgroundDrawable(), which I've tried with a simple new ColorDrawable(). It still doesn't work.

有什么簡單的方法可以在 OnLongPressListener 中觸發系統默認的長按對話框，還是我必須自己移動天堂和地球來實現它?因為如果是這樣的話，我會為它寫一個 Fragment 并在事務中交換它.我知道這會奏效.

Is there any easy way to trigger the system-default long-press dialog in an OnLongPressListener, or will I have to move Heaven and Earth to implement it myself? Because if that's the case, I'll just write a Fragment for it and swap it out in a transaction. I know that'll work.

相關代碼:在啟動片段內部:

The relevant code: Inside the initiating fragment:

RulesDialog dialog;
PopupWindow window;

public void showAddRuleDialog(){
    dialog = new RulesDialog();

    View view = getView();

    window = new PopupWindow(dialog.initViews(this, null), view.getWidth(), view.getHeight(), true);

    window.setBackgroundDrawable(new ColorDrawable());

    dialog.setRulesDialogListener(new rulesDialogListener(){            

        @Override
        public void onSave(ViewHolder holder) {


            addRule(holder);

            window.dismiss();


        }

        @Override
        public void onCancel() {
            window.dismiss();

        }});

    int[] location = {0,0};
    view.getLocationOnScreen(location);



    window.showAtLocation(view, 0, location[0], location[1]);

在規則對話框中:

public class ViewHolder{
    public ViewHolder(View dialogView){
        name = (TextView) dialogView.findViewById(R.id.name);
        response = (TextView) dialogView.findViewById(R.id.response);

        senders = (TextView) dialogView.findViewById(R.id.senders);
        sendersAdd = (Button) dialogView.findViewById(R.id.sendersAdd);
        sendersEdit = (Button) dialogView.findViewById(R.id.sendersEdit);

        timeFrom = (TextView) dialogView.findViewById(R.id.from);
        timeFromEdit = (Button) dialogView.findViewById(R.id.timeBeforeEdit);
        timeTo = (TextView) dialogView.findViewById(R.id.to);
        timeToEdit = (Button) dialogView.findViewById(R.id.timeAfterEdit);

        keywords = (TextView) dialogView.findViewById(R.id.keywords);

        matchCase = (CheckBox) dialogView.findViewById(R.id.matchCase);
        matchAlone = (CheckBox) dialogView.findViewById(R.id.matchAlone);
        matchPlural = (CheckBox) dialogView.findViewById(R.id.matchPlural);

        cancel = (Button) dialogView.findViewById(R.id.cancel);
        save = (Button) dialogView.findViewById(R.id.save);


    }

    TextView name;
    TextView response;
    TextView senders;
    Button sendersAdd;
    Button sendersEdit;
    TextView timeFrom;
    Button timeFromEdit;
    TextView timeTo;
    Button timeToEdit;
    TextView keywords;

    CheckBox matchCase;
    CheckBox matchAlone;
    CheckBox matchPlural;

    Button cancel;
    Button save;

推薦答案

所以我嘗試將RulesDialog 重寫為片段，但效果不佳.當從它們操作的 Fragment 調用時，使 Fragment Transactions 正常工作時遇到問題.

So I tried rewriting RulesDialog as a fragment, and it didn't work out too well. Had issues with making Fragment Transactions work right when called from the Fragments they're operating on.

(我知道這不是碎片化的重點.我現在并不是真的打算編寫一個完全模塊化的應用程序.我只是想推出一款客戶會滿意的產品.)

(I know this isn't the point to fragments. I'm not really aiming to write a completely modular app right now. I just want to come out with a product the customer will be happy with.)

我最終將 RulesDialog 重寫為 Activity，并使用調用片段中的 startActivityForResult().然后使用 setResult() 將編輯后的數據傳回.這一切都很好地協同工作.

I ended up rewriting RulesDialog as an Activity instead, and using startActivityForResult() from the calling fragment. Then passing the edited data back with setResult(). It all works nicely in concert.
