如何在Android上编写一个简单的视频播放器？

    android:id="@+id/videoView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center" />

import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.widget.VideoView;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

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

        // 设置视频播放路径
        String videoUrl = "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4";
        videoView.setVideoURI(Uri.parse(videoUrl));

        // 设置MediaPlayer监听器
        videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                // 开始播放视频
                videoView.start();
            }
        });
    }
}
