一、第一种方法
1.实现步骤
(1).在清单文件中添加权限
(2).在布局文件中写出样式
(3).在java文件中添加地址,实现视频播放
2.整体代码
(1).AndroidManifest.xml清单文件
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.videoplaying">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/Theme.VideoPlaying">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
(2).activity_main.xml布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:orientation="vertical">
<VideoView
android:id="@+id/vv_demo"
android:layout_width="match_parent"
android:layout_height="300dp"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="@+id/btn_begin"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="开始"
android:layout_marginLeft="20dp"
android:background="#8BC34A"
/>
<Button
android:id="@+id/btn_end"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="结束"
android:layout_marginLeft="20dp"
android:background="#2196F3"
/>
</LinearLayout>
</LinearLayout>
(3).MainActivity文件代码
package com.example.videoplaying;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import android.Manifest;
import android.app.Activity;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.MediaController;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
private VideoView vv_demo;
private Button btn_begin;
private Button btn_end;
private MediaController mediaController;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView(); }
private void initView() {
vv_demo=findViewById(R.id.vv_demo);
btn_begin=findViewById(R.id.btn_begin);
btn_end=findViewById(R.id.btn_end);
btn_begin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
init();
}
});
btn_end.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
vv_demo.stopPlayback();
}
});
}
public void init(){
vv_demo=findViewById(R.id.vv_demo);
mediaController=new MediaController(this);
//本地连接地址
// String uri="android.resource://"+getPackageName()+"/"+R.raw.aas;
//网络连接地址
String uri="/sdcard/Pictures/a.mp4";
vv_demo.setVideoURI(Uri.parse(uri));
vv_demo.setMediaController(mediaController);
mediaController.setMediaPlayer(vv_demo);
vv_demo.requestFocus();
vv_demo.start();
}
}

二、第二种方法
1.实现步骤
(1).在布局文件中添加布局页面
(2).创建Utils文件,在文件中放入视频播放的地址
(3).在java文件中,实现视频播放
2.整体代码
(1).activity_main.xml布局文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="200dp">
<VideoView
android:id="@+id/vv_demo"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
</RelativeLayout>
(2).Utils文件代码
package com.example.videoplay;
public class Utils {
public static final String videoUrl="http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4";
}
(3).MainActivity文件代码
package com.example.videoplay;
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.Toast;
import android.widget.VideoView;
public class MainActivity extends AppCompatActivity {
private VideoView vv_demo;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//网络视频
String videoUrl=Utils.videoUrl;
Uri uri= Uri.parse(videoUrl);
vv_demo=findViewById(R.id.vv_demo);
//设置视频控制器
vv_demo.setMediaController(new MediaController(this));
//播放完成回调
vv_demo.setOnCompletionListener(new MyPlayerOnCompletionListener());
//设置视频路径
vv_demo.setVideoURI(uri);
//开始播放视频
vv_demo.start();
}
class MyPlayerOnCompletionListener implements MediaPlayer.OnCompletionListener {
@Override
public void onCompletion(MediaPlayer mp) {
Toast.makeText(MainActivity.this, "播放完成了", Toast.LENGTH_SHORT).show();
}
}
}
