Android项目实现视频播放器

本文实例为大家分享了Android项目实现视频播放器的具体代码，供大家参考，具体内容如下

VideoView控件是播放视频用的，借助它可以完成一个简易的视频播放器。

①在activity_main.xml中编写相应的控件

<?xml version=\"1.0\" encoding=\"utf-8\"?>
<RelativeLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"
 xmlns:tools=\"http://schemas.android.com/tools\"
 android:layout_width=\"match_parent\"
 android:layout_height=\"match_parent\"
 tools:context=\".MainActivity\">
 <ImageView
 android:id=\"@+id/bt_play\"
 android:layout_width=\"80dp\"
 android:layout_height=\"80dp\"
 android:layout_alignParentBottom=\"true\"
 android:layout_centerHorizontal=\"true\"
 android:layout_marginBottom=\"150dp\"
 android:src=\"@android:drawable/ic_media_play\" />
 <VideoView
 android:id=\"@+id/videoview\"
 android:layout_width=\"match_parent\"
 android:layout_height=\"match_parent\" />
</RelativeLayout>

②在MainActivity实现SeekBar.OnSeekChangeListener接口与SurfaceHolder.Callback接口，并重写这两个接口中对应的方法，在这些方法中实现播放视频的。

package com.example.videoview;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.MediaController;
import android.widget.VideoView;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity implements
 View.OnClickListener {
 private VideoView videoView;
 private MediaController controller;
 ImageView iv_play;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 videoView = (VideoView) findViewById(R.id.videoview);
 iv_play = (ImageView) findViewById(R.id.bt_play);
 //拼出在资源文件夹下的视频文件路径String字符串
 String url = \"android.resource://\" + getPackageName() + \"/\" + R.raw.video;
 //字符串解析成Uri
 Uri uri = Uri.parse(url);
 //设置videoview的播放资源
 videoView.setVideoURI(uri);
 //VideoView绑定控制器
 controller = new MediaController(this);
 videoView.setMediaController(controller);
 iv_play.setOnClickListener(this);
 }
 @Override
 public void onClick(View v) {
 switch (v.getId()) {
  case R.id.bt_play:
  play();
  break;
 }
 }
 // 播放视频
 private void play() {
 if (videoView != null && videoView.isPlaying()) {
  iv_play.setImageResource(android.R.drawable.ic_media_play);
  videoView.stopPlayback();
  return;
 }
 videoView.start();
 iv_play.setImageResource(android.R.drawable.ic_media_pause);
 videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
  @Override
  public void onCompletion(MediaPlayer mp) {
  iv_play.setImageResource(android.R.drawable.ic_media_play);
  }
 });
 }
}

③修改清单文件，设置属性screenOrientation为横向。
