视频视图不可见
我需要将 VideoView 添加到 LinearLayout，然后将 LinearLayout 添加到 ViewFlipper。这是我的代码：
LinearLayout l = new LinearLayout(this);
l.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
l.setOrientation(LinearLayout.VERTICAL);
myVideoView = new VideoView(this);
myVideoView.setVideoPath(files[i].getPath());
myVideoView.requestFocus();
myVideoView.setLayoutParams(new LayoutParams(
l.getWidth(), l.getHeight()));
myVideoView.setKeepScreenOn(true)
myVideoView.start();
myVideoView.setId(i);
l.addView(myVideoView);
vf.addView(l);
问题是我看到所有屏幕都是白色的并听到视频的声音，因为视频正在播放但我看不到它。为什么？问题出在哪里？
编辑：
如果我让它
myVideoView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
工作，但视频速度并不慢，当图像出现时，它会突然出现。我希望那个视频像这样慢慢出现然后消失。
I need to add a VideoView to a LinearLayout, and then to add LinearLayout to ViewFlipper. Here is my code :
LinearLayout l = new LinearLayout(this);
l.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
l.setOrientation(LinearLayout.VERTICAL);
myVideoView = new VideoView(this);
myVideoView.setVideoPath(files[i].getPath());
myVideoView.requestFocus();
myVideoView.setLayoutParams(new LayoutParams(
l.getWidth(), l.getHeight()));
myVideoView.setKeepScreenOn(true)
myVideoView.start();
myVideoView.setId(i);
l.addView(myVideoView);
vf.addView(l);
The problem is that I see all screen white and hear the video's sound, because video is playing but I don't see it. Why? Where is the problem?
EDIT :
if I put
myVideoView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
it works but the video is not coming slow, as image appear, it appears suddenly. I want that video to appear slowly and to dissapear like this to.
