Question

我有一个活动，其中包含一个VideoView和一个共享按钮。点击分享按钮，它会调用邮件客户端。这是我的代码：

/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.phrasevideo);


        //extraDataHelper.getPhraseDetails(phraseId);
        btnshare = (ImageView) findViewById(R.id.btnshare);




        videoView = (VideoView) findViewById(R.id.VideoView);

        File f=new File(Environment.getExternalStorageDirectory(), "extras/hello.mp4");
        Uri video = Uri.parse(f.getAbsolutePath());            

        videoView.setVideoURI(video);
    btnshare.setVisibility(View.VISIBLE);
            }});
        videoView.start();



        btnshare.setOnTouchListener(new OnTouchListener(){

            @Override
            public boolean onTouch(View arg0, MotionEvent arg1) {
                // TODO Auto-generated method stub

                final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                emailIntent.setType("text/html"); 
                emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{""}); 
                emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Language Hostess"); 
                String emailText = "<html><body><p>Hi friends</p></body></html>";
                emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, Html.fromHtml(emailText));
                startActivityForResult(Intent.createChooser(emailIntent, "Email:"), 1);
                return false;
            }});

    }

一切都很好。但是当我在发送或丢弃邮件后回到应用程序时，videoView只是黑色。在这里，我想提一下，只有在视频没有播放时才会出现分享按钮。为什么会这样？这个问题的解决方案是什么？

如果屏幕有视频，Android会调用邮件问题
