我想在我的应用程序中播放视频。我使用ListView创建了自定义VideoView。 VideoView显示成功，但有一个问题是，当我移动列表视图VideoView时，它会改变其位置。这在我的应用程序中看起来不太好。我的要求是，点击button视频时，只能在列表视图的该区域播放。我怎么能做到这一点？
以下是在VideoView中显示ListView的代码：
public class MyVideoAdapter extends BaseAdapter {
Context context;
String a[];
LayoutInflater inflate;
VideoView vv;
ImageButton img;
public MyVideoAdapter(Context context, String[] a) {
this.context = context;
this.a = a;
inflate = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return a.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (convertView == null)
v = inflate.inflate(R.layout.row, null);
img = (ImageButton) v.findViewById(R.id.imageButton1);
String ans = a[position];
if (ans.equals("one")) {
vv = (VideoView) v.findViewById(R.id.VideoView);
MediaController mc = new MediaController(context);
mc.setAnchorView(vv);
mc.setMediaPlayer(vv);
// Uri uri=Uri.parse("https://www.dropbox.com/s/d5blvemu8yse38s/kesari.mp4");
// vv.setMediaController(mc);
String path = "android.resource://com.example.wealthcreation/raw/kesari";
vv.setVideoURI(Uri.parse(path));
img.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
img.setVisibility(View.INVISIBLE);
vv.start();
}
});
// img.setImageResource(R.drawable.k1);
// ImageButton img=(ImageButton)v.findViewById(R.id.imageButton1);
// Button btn1=(Button)v.findViewById(R.id.btnplay);
/*
img.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
vv.setVisibility(View.VISIBLE);
img.setVisibility(View.GONE);
MediaController mc = new MediaController(context);
mc.setAnchorView(vv);
mc.setMediaPlayer(vv);
// Uri uri=Uri.parse("https://www.dropbox.com/s/d5blvemu8yse38s/kesari.mp4");
vv.setMediaController(mc);
String path = "android.resource://com.example.wealthcreation/raw/kesari";
vv.setVideoURI(Uri.parse(path));
vv.start();
String videoId = "CUuBdtsQx6U";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:"

直到我发现这篇文章之后，我才对此感到难过： https://stackoverflow.com/a/6832598/3367142
简而言之，为您的VideoView设置透明背景
