Android 饺子播放器

在很多项目里面都有视频一类，Android中视频播放框架有VideoView，SurfaceView+MediaPlayer，Vitamin，jiaozivideoplayer

等几种。一般就看公司要求，没有要求就看自己的喜好。我就喜欢用饺子播放器，下面就最简单的实现一下：

一   导入依赖

饺子依赖：
implementation 'cn.jzvd:jiaozivideoplayer:6.2.4'

图片加载依赖
implementation 'com.github.bumptech.glide:glide:4.3.1'

二  xml 布局

<?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">

    <cn.jzvd.JZVideoPlayerStandard
        android:id="@+id/mJC"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="fitXY"
        >
    </cn.jzvd.JZVideoPlayerStandard>
</LinearLayout>

 注意：如果需要横竖屏切换需要在AndroidManifest.xml中加上以下代码，没有添加的话切换的时候会报错：

android:configChanges="orientation|screenSize|keyboardHidden"
android:screenOrientation="portrait

三 代码实现

        setContentView(R.layout.activity_main);
           
        initView();
    }
    private void initView() {
        //初始化
        mJC = (JZVideoPlayerStandard) findViewById(R.id.mJC);
        //用于实现重力感应下切换横竖屏
        sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        jzAutoFullscreenListener = new JZVideoPlayer.JZAutoFullscreenListener();
        //设置图片为全屏
        mJC.thumbImageView.setScaleType(ImageView.ScaleType.FIT_XY);
        //内置视频的高度，可以去除黑边

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mJC.thumbImageView.setImageBitmap(bitmap);
                    }
                });
            }
        }).start();

        //视频的缩略图地址
       //Glide.with(getApplicationContext()).load("http://p0.so.qhmsg.com/bdr/_240_/t01c10808f98a39bd4f.jpg").into(mJC.thumbImageView);

        //播放比例,可以设置为16:9,4:3
        mJC.widthRatio = 4;
        mJC.heightRatio = 3;

        //设置全屏播放
        JZVideoPlayer.FULLSCREEN_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;  //横向
        JZVideoPlayer.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;  //纵向

    }
    //获取视频的第一帧作为视频的缩略图(网络视频)：

    private Bitmap createVideoThumbnail(String url, int width, int height) {
        Bitmap bitmap = null;
        MediaMetadataRetriever retriever = new MediaMetadataRetriever();
        int kind = MediaStore.Video.Thumbnails.MINI_KIND;
        try {
            if (Build.VERSION.SDK_INT >= 14) {
                retriever.setDataSource(url, new HashMap<String, String>());
            } else {
                retriever.setDataSource(url);
            }
            bitmap = retriever.getFrameAtTime();
        } catch (IllegalArgumentException ex) {
            // 假设这是一个损坏的视频文件
        } catch (RuntimeException ex) {
            //假设这是一个损坏的视频文件
        } finally {
            try {
                retriever.release();
            } catch (RuntimeException ex) {
                // 清理时忽略故障
            }
        }
        if (kind == MediaStore.Images.Thumbnails.MICRO_KIND && bitmap != null) {
            bitmap = ThumbnailUtils.extractThumbnail(bitmap, width, height, ThumbnailUtils.OPTIONS_RECYCLE_INPUT);
        }
        return bitmap;
    }
    @Override
    public void onBackPressed() {
        if (JZVideoPlayer.backPress()) {
            return;
        }
        super.onBackPressed();
    }
    @Override
