我有以下代码可以在屏幕上显示的任何内容之上显示 VideoView。
public void showVideo(float x, float y) {
AbsoluteLayout.LayoutParams params = (AbsoluteLayout.LayoutParams) video.getLayoutParams();
params.width=190;
params.height=240;
params.x = (int) x;
params.y = (int) y;
video.requestLayout();
video.setVisibility(View.VISIBLE);
video.setVideoURI(Uri.parse("file://sdcard/test-edition/sample.mp4"));
video.start();
}
（是的，这使用 AbsoluteLayout，我需要在特定位置显示它（任何其他解决方案都值得赞赏））。
“file://sdcard/test-edition/sample.mp4”的这个路径是我为测试目的下载的有效 mp4。
显示时，系统只显示“无法播放视频。发生错误。”，但 Logcat 上没有堆栈跟踪。如果它有用的话，我在尝试运行它时会有这个详细的信息：
