Android实现VideoView重复播放本地视频（无缝播放）

Android实现VideoView重复播放本地视频（无缝播放）

话不多说，先上图（本来是完整的图，不知道为啥显示这么一点点，大家还是下载下来看吧）

好多人应该都遇见过播放视频间隙会出现黑屏的问题，下面这块代码可以解决此问题。

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
            @Override
            public void onPrepared(MediaPlayer mp) {
                videoView.setOnInfoListener(new MediaPlayer.OnInfoListener() {
                    @Override
                    public boolean onInfo(MediaPlayer mp, int what, int extra) {
                        videoView.setBackgroundColor(Color.TRANSPARENT);
                        return false;
                    }
                });
            }
        });

注：仅支持4.4以上版本。

多视频重复播放请看Main2Activity.class

下面附上代码：

MainActivity.class

package com.bangni.videoplay;

import android.content.Intent;
import android.graphics.Color;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Build;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.VideoView;

/**
 * 使用video重复播放单条本地视频
 */
public class MainActivity extends AppCompatActivity implements View.OnClickListener {

    private VideoView videoView;

    private Button bt_next;

    private String externalFilesDir;

    public String path = "/storage/emulated/0/Android/data/com.bangni.tyy/files/video/1214018654434938880.mp4";



//    /storage/emulated/0/Android/data/com.bangni.tyy/files/video/1218443884820303872.mp4
//    /storage/emulated/0/Android/data/com.bangni.tyy/files/video/1214716732949889024.mp4

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        videoView = findViewById(R.id.videoview);
        bt_next = findViewById(R.id.bt_next);

        bt_next.setOnClickListener(this);

        videoView.setVideoURI(Uri.parse(path));
        videoView.start();
//        videoView.seekTo(0);



        videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                Log.d("TYY_CC_wjll", "我播完了");
//                nextVideo();
                videoView.setVideoURI(Uri.parse(path));
                videoView.start();
            }
        });

        videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
            @Override
            public void onPrepared(MediaPlayer mp) {
                videoView.setOnInfoListener(new MediaPlayer.OnInfoListener() {
                    @Override
                    public boolean onInfo(MediaPlayer mp, int what, int extra) {
                        videoView.setBackgroundColor(Color.TRANSPARENT);
                        return false;
                    }
                });
            }
        });

        videoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
            @Override
            public boolean onError(MediaPlayer mp, int what, int extra) {
                videoView.stopPlayback(); //播放异常，则停止播放，防止弹窗使界面阻塞
                return true;
            }
        });
    }

    @Override
    public void onClick(View v) {
        int temdId = v.getId();
        if(temdId == R.id.bt_next){
            startActivity(new Intent(MainActivity.this, Main2Activity.class));
            finish();
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        Log.d("TAG", "onPause-------------");
        videoView.pause();
    }

    @Override
    protected void onStop() {
        super.onStop();
        Log.d("TAG", "onStop-------------");
    }

    @Override
    protected void onResume() {
        super.onResume();
        Log.d("TAG", "onResume-------------");
        videoView.start();
    }
}

注：这个是单视频重复播放的主要代码

Main2Activity.class：

package com.bangni.videoplay;

import android.graphics.Bitmap;
import android.graphics.Color;
import android.media.MediaMetadataRetriever;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Build;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.ImageView;
import android.widget.VideoView;

import java.util.ArrayList;
import java.util.List;

/**
 * 多个本地视频重复播放
 */
public class Main2Activity extends AppCompatActivity {

    private VideoView videoView;

    private ImageView video_one;

    private int posVideoIndex = 0;

    private List datas = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

        videoView = findViewById(R.id.videoview2);
        video_one = findViewById(R.id.video_one);

        datas.add("/storage/emulated/0/Android/data/com.bangni.tyy/files/video/1214018654434938880.mp4");
        datas.add("/storage/emulated/0/Android/data/com.bangni.tyy/files/video/1218443884820303872.mp4");
        datas.add("/storage/emulated/0/Android/data/com.bangni.tyy/files/video/1214716732949889024.mp4");

        startVideos();

        videoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                Log.d("TYY_CC_wjll", "我播完了");
                video_one.setVisibility(View.VISIBLE);
                posVideoIndex++;
                if(posVideoIndex >= datas.size()){
                    posVideoIndex = 0;
                }
                startVideos();
            }
        });

        videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR1)
            @Override
            public void onPrepared(MediaPlayer mp) {
                videoView.setOnInfoListener(new MediaPlayer.OnInfoListener() {
                    @Override
                    public boolean onInfo(MediaPlayer mp, int what, int extra) {
                        video_one.setVisibility(View.GONE);
                        videoView.setBackgroundColor(Color.TRANSPARENT);
                        return false;
                    }
                });
            }
        });

        videoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
            @Override
            public boolean onError(MediaPlayer mp, int what, int extra) {
                videoView.stopPlayback(); //播放异常，则停止播放，防止弹窗使界面阻塞
                return true;
            }
        });

    }

    /**
     * 播放视频
     */
    private void startVideos() {
        video_one.setImageBitmap(getVideoOne(datas.get(posVideoIndex)));
        videoView.setVideoURI(Uri.parse(datas.get(posVideoIndex)));
        videoView.start();
    }

    /**
     * 获取视频的第一帧
     * @param sdPath
     * @return
     */
    private Bitmap getVideoOne(String sdPath){
        MediaMetadataRetriever media = new MediaMetadataRetriever();
        media.setDataSource(sdPath);// videoPath 本地视频的路径
        return media.getFrameAtTime(1, MediaMetadataRetriever.OPTION_CLOSEST_SYNC );
    }

}

注：这个是多视频重复播放的主要代码；

还有一个小问题，VideoView设置宽高后并无效果谁怎么回事呢？？
重写一下VideoView就好
代码如下：

package com.bangni.videoplay.view;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class FullScreenVideoView extends VideoView {

    public FullScreenVideoView(Context context) {
        super(context);
    }

    public FullScreenVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FullScreenVideoView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
//        WindowManager wm = (WindowManager) getContext().getSystemService(Context.WINDOW_SERVICE);
//        int width = wm.getDefaultDisplay().getWidth();
//        int height = wm.getDefaultDisplay().getHeight();
        setMeasuredDimension(widthMeasureSpec, heightMeasureSpec);
    }
}

注：注释掉的打开就是全屏设置。不打开就是按照宽高设置的。

以上就是所有的代码
