当尝试在Adapter类中单击ListView项时，我试图显示一个AlertDialog，但是黑屏覆盖了该对话框

Question

I have an adapter class that is loading an ArrayList of items into a ListView. It does this fine. I am also trying to create an AlertDialog popup of an item in the ListView whenever a hyperlinked text is clicked in a ListView item, referencing a specific ListView item. However, when I show the AlertDialog the dialog has a black screen on top of it covering everything.

From what I've read so far on other posts the issue is possibly being caused because the ListView item is already inflated in the ListView and I'm trying to reinflate it in the AlertDialog. If that is the issue then, then how can I get a reference to the already inflated ListView item, show it in the AlertDialog, all from the adapter class.

Here's a picture of what's happening.

Here's the following code for my adapter class we well.

public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);


    listView = inflater.inflate(R.layout.list_item_reply, null);

    TextView textView_name = (TextView) listView.findViewById(R.id.textViewName);
    TextView textView_time = (TextView) listView.findViewById(R.id.textViewTime);
    TextView textView_title = (TextView) listView.findViewById(R.id.textViewThreadTitle);

    textView_name.setText(this.reply_list.get(position).getName());
    textView_time.setText(this.reply_list.get(position).getTime_diff() + " ago");
    textView_title.setText(Html.fromHtml(reply_list.get(position).getTitle()));

    Spannable clickableMessage = (Spannable) textView_message.getText();
    clickableMessage = Find_String_Matches(clickableMessage);
    textView_message.setText(clickableMessage, TextView.BufferType.SPANNABLE);

    return listView;
}

private Spannable Find_String_Matches(Spannable text){
    Pattern pattern = Pattern.compile(thread_regex);
    Matcher matcher = pattern.matcher(text.toString());

    while (matcher.find()) {
        Log.d("start", "Start index: " + matcher.start());
        Log.d("end", " End index: " + matcher.end());
        Log.d("found", " Found: " + matcher.group());

        text = addClickablePart(text, matcher.start(), matcher.end());
    }

    return text;
};

public void Popup_Thread(final int pos){
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(context);
    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View listReplyView = getView(pos, null, null);
    dialogBuilder.setView(listReplyView);

    AlertDialog alertDialog = dialogBuilder.create();
    alertDialog.show();
};

This should work. There is no need to inflate the layout

AlertDialog.Builder builder = new AlertDialog.Builder(context);
                builder.setCancelable(true);
                builder.setMessage("Your message");
                View listReplyView = getView(pos, null, null);
                dialogBuilder.setView(listReplyView);
                // Yes option
                builder.setPositiveButton(R.string.positive_option,
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                              //smth
                            }
                        });

                // Cancel option
                builder.setNegativeButton(R.string.negative_option,
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {
                                dialog.dismiss(); // If cancel is pressed, dialog is closed
                            }
                        });

                // Show the dialog window
                AlertDialog dialog = builder.create();
                dialog.show();

Try to inflate your layout item :

public void Popup_Thread(final int pos){
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View dialogView = inflater.inflate(R.layout. list_item_reply, null);
    dialogBuilder.setView(dialogView);

// set value into textview
TextView textView_name = (TextView) dialogView.findViewById(R.id.textViewName);
TextView textView_time = (TextView) 
dialogView.findViewById(R.id.textViewTime);
TextView textView_title = (TextView) 
dialogView.findViewById(R.id.textViewThreadTitle);

textView_name.setText(this.reply_list.get(pos).getName());
textView_time.setText(this.reply_list.get(pos).getTime_diff() + " ago");
textView_title.setText(Html.fromHtml(reply_list.get(pos).getTitle()));

 AlertDialog alertDialog = dialogBuilder.create();
    alertDialog.show();
};

Answer 3

i have a good magic for you

Create a layout same as custom ListView item Layout and when you show() your dialog box get current item and put in same layout and inflate it in dialog box

Answer 4

Please provide transperent theme for dialog.

add following style in values\\styles.xml

 <?xml version="1.0" encoding="utf-8"?> <resources> <style name="Theme.Transparent" parent="android:Theme"> <item name="android:windowIsTranslucent">true</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowContentOverlay">@null</item> <item name="android:windowNoTitle">true</item> <item name="android:windowIsFloating">true</item> <item name="android:backgroundDimEnabled">false</item> </style> </resources> 

and provide it like ......

 listView = inflater.inflate(R.layout.list_item_reply, R.styles.Theme.Transparent);
