Android原生视频播放VideoView的使用

本文实例为大家分享了Android原生视频播放VideoView的具体代码，供大家参考，具体内容如下

布局文件activity_video.xml

对应的Avtivity：VideoActivity.java

package com.example.administrator.main;
 
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.view.MotionEvent;
import android.view.View;
import android.widget.MediaController;
import android.widget.ProgressBar;
import android.widget.RelativeLayout;
import android.widget.VideoView;
 
public class VideoActivity extends AppCompatActivity {
 private ProgressBar progressBar;
 private VideoView videoView;
 private MediaController mediaController;
 private int intPositionWhenPause = -1;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_video);
 
  //调用系统自带视频播放或者安装的第三方播放器
//  Uri uri=Uri.parse("http://vd3.bdstatic.com/mda-ig4tp6gnqwu5we8i/mda-ig4tp6gnqwu5we8i.mp4");
//  Intent intent=new Intent(Intent.ACTION_VIEW);
//  intent.setDataAndType(uri,"video
 public void initVideoView() {
  //初始化进度条

  //初始化VideoView
  videoView = (VideoView) findViewById(R.id.videoView);
  //初始化videoview控制条
  mediaController = new MediaController(this);
  //设置videoview的控制条
  videoView.setMediaController(mediaController);
  //设置显示控制条
  mediaController.show(0);
  //设置播放完成以后监听
  videoView.setonCompletionListener(new MediaPlayer.onCompletionListener() {
   @Override
   public void onCompletion(MediaPlayer mp) {
 
   }
  });
  //设置发生错误监听，如果不设置videoview会向用户提示发生错误
  videoView.setonErrorListener(new MediaPlayer.onErrorListener() {
   @Override
   public boolean onError(MediaPlayer mp, int what, int extra) {
    return false;
   }
  });
  //设置在视频文件在加载完毕以后的回调函数
  videoView.setonPreparedListener(new MediaPlayer.onPreparedListener() {
   @Override
   public void onPrepared(MediaPlayer mp) {
    progressBar.setVisibility(View.GONE);
    videoView.start();
   }
  });
  //设置videoView的点击监听
  videoView.setonTouchListener(new View.onTouchListener() {
   @Override

   }
  });
  //设置网络视频路径
  Uri uri = Uri.parse("http://vd3.bdstatic.com/mda-ig4tp6gnqwu5we8i/mda-ig4tp6gnqwu5we8i.mp4");
  videoView.setVideoURI(uri);
  //设置为全屏模式播放
  setVideoViewLayoutParams(2);
 }
 
 
 public void setVideoViewLayoutParams(int paramsType) {
  //全屏模式
  if (1 == paramsType) {
   //设置充满整个父布局
   RelativeLayout.LayoutParams LayoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
   //设置相对于父布局四边对齐
   LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
   LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
   LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
   LayoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
   //为VideoView添加属性
   videoView.setLayoutParams(LayoutParams);
  } else {
   //窗口模式
   //获取整个屏幕的宽高
   DisplayMetrics DisplayMetrics = new DisplayMetrics();
   this.getWindowManager().getDefaultDisplay().getMetrics(DisplayMetrics);
   //设置窗口模式距离边框50
   int videoHeight = DisplayMetrics.heightPixels;
   int videoWidth = DisplayMetrics.widthPixels;
   RelativeLayout.LayoutParams LayoutParams = new RelativeLayout.LayoutParams(videoWidth, videoHeight);
   //设置居中
   LayoutParams.addRule(RelativeLayout.ALIGN_TOP);
   //为VideoView添加属性
   videoView.setLayoutParams(LayoutParams);
  }
 }
 
 
 @Override
 protected void onPause() {
  super.onPause();
  //如果当前页面暂停则保存当前播放位置，全局变量保存
  intPositionWhenPause = videoView.getCurrentPosition();
  //停止回放视频文件
  videoView.stopPlayback();
 }
 
 
 @Override
 protected void onResume() {
  super.onResume();
  //跳转到暂停时保存的位置
  if (intPositionWhenPause >= 0) {
   videoView.seekTo(intPositionWhenPause);
   //初始播放位置
   intPositionWhenPause = -1;
  }
 }
}
