android 播放视频饺子播放器解救黑边 拉伸全屏铺满状态 去掉返回键

我的布局是这样的

所以视频播放器是固定大小的  当然是有屏幕适配的
  <cn.jzvd.JZVideoPlayerStandard
            android:scaleType="fitXY"
            android:layout_above="@+id/btn_luyin"
            android:layout_marginBottom="6dp"
            android:layout_centerHorizontal="true"
            android:id="@+id/jiecao_video"
            android:layout_width="321.55dp"
            android:layout_height="169.45dp"
            ></cn.jzvd.JZVideoPlayerStandard>

 

 

 

 jiecao_video.setUp(alist.get(0).getVideo_url(), JCVideoPlayerStandard.SCREEN_LAYOUT_NORMAL, "");

                                        jiecao_video.SAVE_PROGRESS = false;
                                        jiecao_video.TOOL_BAR_EXIST = false;
                                 
                                        jiecao_video.thumbImageView.setScaleType(ImageView.ScaleType.FIT_XY);

//下边这个是视频的缩略图地址
//                                        Glide.with(getApplicationContext()).load(图片地址)
//                                                .into(videoplayer.thumbImageView);
                                      
                                        JZVideoPlayer.setVideoImageDisplayType(JZVideoPlayer.VIDEO_IMAGE_DISPLAY_TYPE_FILL_PARENT);

 @Override
    protected void onDestroy() {
        super.onDestroy();
        if (jiecao_video != null)
            jiecao_video.releaseAllVideos();
    }
    @Override
    protected void onPause() {
        super.onPause();
        JZVideoPlayer.releaseAllVideos();
    }
