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。
