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

我有一个适配器类，它将项目的ArrayList加载到ListView中。 这样做很好。 每当在ListView项目中单击超链接的文本时，我也会尝试在ListView中创建项目的AlertDialog弹出窗口，并引用特定的ListView项目。 但是，当我显示AlertDialog时，对话框顶部有一个黑屏，覆盖了所有内容。

根据我到目前为止在其他帖子上所读的内容，可能是由于ListView项已经在ListView中膨胀，并且我试图在AlertDialog中对其进行膨胀而引起的。 如果那是问题所在，那么我如何获得对已经膨胀的ListView项的引用，将其显示在AlertDialog中，全部来自适配器类。

这是正在发生的事情的图片。

这是我的适配器类的以下代码，我们很好。

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();
};

这应该工作。 无需增加布局

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();

尝试为您的布局项目充气：

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();
};

我对你有很好的魔力

创建一个与自定义ListView项布局相同的布局，并在show（）时，对话框获取当前项并放入相同的布局，然后在对话框中对其进行充气

Answer 4

请提供对话的透明主题。

在values \\ styles.xml中添加以下样式

 <?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> 

并提供......

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