問題描述

大家好我在對話框視圖中嵌入視頻視圖時遇到問題

Hi all I have a problem with embedding a video view inside a dialog view

一切正常，只是對話框中顯示的視頻比在活動的其余部分中顯示的要暗得多

everything works fine except that the video displayed in the Dialog is much darker that if displayed in the rest of the activity

有什么想法嗎?

這里有一些代碼

button1main.setOnClickListener(new OnClickListener() {

                public VideoView videoView = null;
                @Override
                public void onClick(View v) {
                    //set up dialog
                    Dialog dialog = new Dialog(CustomDialog.this);
                    dialog.setContentView(R.layout.maindialog);
                    //dialog.setTitle("This is my custom dialog box");
                    dialog.setCancelable(true);


                    this.videoView = (VideoView) dialog.findViewById(R.id.video);
                    VideoPlayer vp = new VideoPlayer(this.videoView, null);
                    vp.playVideo();

                    //set up button
                    Button button = (Button) dialog.findViewById(R.id.Button01);
                    button.setOnClickListener(new OnClickListener() {
                    @Override
                        public void onClick(View v) {
                            finish();
                        }
                    });
                    //now that the dialog is set up, it's time to show it    
                    dialog.show();
                }
            });

推薦答案

我實際上找到了解決方案(或者至少在我的情況下)

I actually found the solution to this (or at least in my case)

這似乎是 android 的一個錯誤，其中視頻視圖是在對話框后面創(chuàng)建的，當對話框打開時，它會使包括視頻在內的背景視圖變暗

it seems its a bug from android where the Video View is created behind the Dialog and when the Dialog opens it dims the background views including the video

我應用的快速修復"是

WindowManager.LayoutParams a = dialog.getWindow().getAttributes();
a.dimAmount = 0;
dialog.getWindow().setAttributes(a);

它們可能是一個更好的解決方案，例如傳遞對話框的上下文，而不是使用相同的上下文來創(chuàng)建對話框和視頻視圖(如果有時間我會稍后檢查)

they might be a solution better solution like passing the context of the Dialog box instead of using the same context for creating the Dialog and the Video View (I'll check later if I get sone time)
