这篇文章主要介绍“Flutter怎么使用Android原生播放器”，在日常操作中，相信很多人在Flutter怎么使用Android原生播放器问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”Flutter怎么使用Android原生播放器”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

创建插件VideoViewPlugin实现FlutterPlugin：

package io.flutter.plugins.videoplayer;import android.util.Log;import androidx.annotation.NonNull;import io.flutter.embedding.engine.plugins.FlutterPlugin;import io.flutter.embedding.engine.plugins.activity.ActivityAware;import io.flutter.embedding.engine.plugins.activity.ActivityPluginBinding;public class VideoViewPlugin implements FlutterPlugin, ActivityAware {    private final static String TAG = "VideoViewPlugin";    FlutterPluginBinding fpBinding;    @Override    public void onAttachedToEngine(@NonNull FlutterPluginBinding binding) {        fpBinding = binding;        Log.e(TAG, "onAttachedToEngine");    }    @Override    public void onDetachedFromEngine(@NonNull FlutterPluginBinding binding) {        Log.e(TAG, "onDetachedFromEngine");    }    @Override    public void onAttachedToActivity(@NonNull ActivityPluginBinding apBinding) {        fpBinding.getPlatfORMViewReGIStry().registerViewFactory("plugins.my_video_player/view", new VideoViewFactory(fpBinding, apBinding));        Log.e(TAG, "onAttachedToActivity");    }    @Override    public void onDetachedFroMactivityForConfiGChanges() {        Log.e(TAG, "onDetachedFromActivityForConfigChanges");    }    @Override    public void onReattachedToActivityForConfigChanges(@NonNull ActivityPluginBinding binding) {        Log.e(TAG, "onReattachedToActivityForConfigChanges");    }    @Override    public void onDetachedFromActivity() {        Log.e(TAG, "onDetachedFromActivity");    }}

由于引用视频播放器时需要用到Activity的context，所以实现了ActivityAware接口，在onAttachedToActivity方法中注册PlatformViewFactory！

创建VideoViewFactory实现PlatformViewFactory：

package io.flutter.plugins.videoplayer;import android.content.Context;import io.flutter.Log;import io.flutter.embedding.engine.plugins.FlutterPlugin;import io.flutter.embedding.engine.plugins.activity.ActivityPluginBinding;import io.flutter.plugin.common.StandardMessageCodec;import io.flutter.plugin.platform.PlatformView;import io.flutter.plugin.platform.PlatformViewFactory;public class VideoViewFactory extends PlatformViewFactory {    private final static String TAG = "VideoViewFactory";    private final FlutterPlugin.FlutterPluginBinding fpBinding;    private final ActivityPluginBinding apBinding;    public VideoViewFactory(FlutterPlugin.FlutterPluginBinding fpBinding, ActivityPluginBinding apBinding) {        super(StandardMessageCodec.INSTANCE);        Log.e(TAG, "VideoViewFactory");        this.fpBinding = fpBinding;        this.apBinding = apBinding;    }    @Override    public PlatformView create(Context context, int viewId, Object args) {        Log.e(TAG, "PlatformView-create:" + args.toString());        return new VideoViewPlayer(args.toString(), fpBinding, apBinding);    }}

创建VideoViewPlayer，实现PlatformView和MethodChannel.MethodCallHandler：

package io.flutter.plugins.videoplayer;import android.app.Activity;import android.content.Context;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import androidx.annotation.NonNull;import androidx.annotation.Nullable;import com.th.kjjl_flutter.R;import com.videoplayer.player.VideoView;import io.flutter.embedding.engine.plugins.FlutterPlugin;import io.flutter.embedding.engine.plugins.activity.ActivityPluginBinding;import io.flutter.plugin.common.MethodCall;import io.flutter.plugin.common.MethodChannel;import io.flutter.plugin.platform.PlatformView;public class VideoViewPlayer implements PlatformView, MethodChannel.MethodCallHandler {    private final static String TAG = "VideoPlayerView";    Activity context;    private VideoView videoView;    private MethodChannel methodChannel;    VideoViewPlayer(String viewId, FlutterPlugin.FlutterPluginBinding fpBinding, ActivityPluginBinding apBinding) {        this.context = apBinding.getActivity();        videoView = (VideoView) LayoutInflater.from(context).inflate(R.layout.video_player, null);        methodChannel = new MethodChannel(fpBinding.getBinaryMessenger(), "my_video_player_" + viewId);        methodChannel.setMethodCallHandler(this);    }    @Override    public void onMethodCall(@NonNull MethodCall call, @NonNull MethodChannel.Result result) {        Log.e(TAG, "call.method>>" + call.method);        switch (call.method) {            case "setUrl":                String url = call.arguments.toString();                videoView.initVideoController(context);                videoView.setUrl(url);                break;            case "start":                videoView.start();                break;            case "pause":                videoView.pause();                break;            case "release":                videoView.pause();                videoView.release();                break;            case "stopFullScreen":                videoView.stopFullScreen();                break;            default:                result.notImplemented();        }    }    @Nullable    @Override    public View getView() {        return videoView;    }    @Override    public void dispose() {        Log.e(TAG, "dispose>>");        videoView.pause();        videoView.release();        methodChannel.setMethodCallHandler(null);        methodChannel = null;    }}

其中的VideoView即引用的第三方播放器库，你可以根据自己情况，使用常见的安卓端开源播放器如GSY，饺子，DKPlayer等！

video_player.xml：

<?xml version="1.0" encoding="utf-8"?><com.videoplayer.player.VideoView xmlns:android="Http://schemas.android.com/apk/res/android"    android:id="@+id/videoView"    android:layout_width="match_parent"    android:layout_height="match_parent" />

在MainActivity中注册插件：

class MainActivity : FlutterActivity() {    override fun onCreate(savedInstanceState: Bundle?) {        super.onCreate(savedInstanceState)        flutterEngine!!.plugins.add(VideoViewPlugin())    }}

注意：不要在GeneratedPluginRegistrant中去注册插件包括iOS，这个类由系统自动生成其它第三方插件注册代码！安卓端在MainActivity中注册，IOS端在AppDelegate中注册！
