简单视频播放器的使用 一、简单使用videoView和MediaController实现播放控制 1、添加需要的权限 2、设置布局 3、实例化VideoView VideoView videoView = (VideoView) findViewById(R.id.main_video); MediaController controller = new MediaController(this);//实例化控制器 // String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"jiaoxue.mp4"; /** * 本地播放 */ // videoView.setVideoPath("path"); /** * 网络播放 */ videoView.setVideoURI(Uri.parse("http://192.168.1.109:8080/video/jiaoxue.mp4")); /** * 将控制器和播放器进行互相关联 */ controller.setMediaPlayer(videoView); videoView.setMediaController(controller);二、自定义播放器 （贴上源码） 视频Java类： public class TestMovieActivity extends BaseActivity { public static final int UPDATA_VIDEO_NUM = 1; private CustomVideoView videoView; private MediaController controller;//控制器 private RelativeLayout videoLayout; private LinearLayout controllerLayout;//播放器的总控制布局 private SeekBar play_seek, volume_seek;//播放进度和音量控制进度 private ImageView play_controller_image, screen_image,volume_Image; private TextView current_time_tv, totally_time_tv; private String path; private int screen_width, screen_height; private AudioManager audioManager;//音量控制器 private boolean screen_flag = true;//判断屏幕转向 @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); //实例化音量控制器 audioManager = (AudioManager) getSystemService(AUDIO_SERVICE); setContentView(R.layout.act_testmovie); initView(); initData(); initViewOnClick(); // controller = new MediaController(this);//实例化控制器 // path = Environment.getExternalStorageDirectory().getAbsolutePath()+"jiaoxue.mp4"; /** * 本地播放 */ // videoView.setVideoPath(""); /** * 网络播放 */ videoView.setVideoURI(Uri.parse("http://192.168.1.109:8080/video/jiaoxue.mp4")); //视频播放时开始刷新 // videoView.start(); play_controller_image.setImageResource(R.mipmap.video_play_blue); // handler.sendEmptyMessage(UPDATA_VIDEO_NUM); /** * 将控制器和播放器进行互相关联 */ // controller.setMediaPlayer(videoView); // videoView.setMediaController(controller); } @Override protected void onPause() { super.onPause(); handler.removeMessages(UPDATA_VIDEO_NUM); } @Override protected void onDestroy() { super.onDestroy(); handler.removeMessages(UPDATA_VIDEO_NUM); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); // 判断当前屏幕的横竖屏状态 int screenOritentation = getResources().getConfiguration().orientation; if (screenOritentation == Configuration.ORIENTATION_LANDSCAPE) { //横屏时处理 setVideoScreenSize(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); volume_seek.setVisibility(View.VISIBLE); volume_Image.setVisibility(View.VISIBLE); screen_flag = false; //清除全屏标记，重新添加 getWindow().clearFlags((WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN)); getWindow().addFlags((WindowManager.LayoutParams.FLAG_FULLSCREEN)); } else { //竖屏时处理 setVideoScreenSize(ViewGroup.LayoutParams.MATCH_PARENT, DisplayUtils.dp2px(mContext,240)); screen_flag = true; volume_seek.setVisibility(View.GONE); volume_Image.setVisibility(View.GONE); //清除全屏标记，重新添加 getWindow().clearFlags((WindowManager.LayoutParams.FLAG_FULLSCREEN)); getWindow().addFlags((WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN)); } } /** * 通过handler对播放进度和时间进行更新 */ private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); if (msg.what == UPDATA_VIDEO_NUM) { //获取视频播放的当前时间 int currentTime = videoView.getCurrentPosition(); //获取视频的总时间 int totally = videoView.getDuration(); //格式化显示时间 updataTimeFormat(totally_time_tv, totally); updataTimeFormat(current_time_tv, currentTime); //设置播放进度 play_seek.setMax(totally); play_seek.setProgress(currentTime); //自己通知自己更新 handler.sendEmptyMessageDelayed(UPDATA_VIDEO_NUM, 500);//500毫秒刷新 } } }; /** * 设置横竖屏时的视频大小 * * @param width * @param height */ private void setVideoScreenSize(int width, int height) { //获取视频控件的布局参数 ViewGroup.LayoutParams videoViewLayoutParams = videoView.getLayoutParams(); //设置视频范围 videoViewLayoutParams.width = width; videoViewLayoutParams.height = height; videoView.setLayoutParams(videoViewLayoutParams); //设置视频和控制组件的layout ViewGroup.LayoutParams videoLayoutLayoutParams= videoLayout.getLayoutParams(); videoLayoutLayoutParams.width = width; videoLayoutLayoutParams.height = height; videoLayout.setLayoutParams(videoLayoutLayoutParams); } /** * 时间格式化 * * @param textView 时间控件 * @param millisecond 总时间 毫秒 */ private void updataTimeFormat(TextView textView, int millisecond) { //将毫秒转换为秒 int second = millisecond / 1000; //计算小时 int hh = second / 3600; //计算分钟 int mm = second % 3600 / 60; //计算秒 int ss = second % 60; //判断时间单位的位数 String str = null; if (hh != 0) {//表示时间单位为三位 str = String.format("%02d:%02d:%02d", hh, mm, ss); } else { str = String.format("%02d:%02d", mm, ss); } //将时间赋值给控件 textView.setText(str); } /** * 按钮点击事件 */ private void initViewOnClick() { //播放按钮事件 play_controller_image.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //判断播放按钮的状态 if (videoView.isPlaying()) { play_controller_image.setImageResource(R.mipmap.video_play_blue); //视频暂停 videoView.pause(); //当视频处于暂停状态，停止handler的刷新 handler.removeMessages(UPDATA_VIDEO_NUM); } else { play_controller_image.setImageResource(R.mipmap.video_pause_white); videoView.start(); //当视频播放时，通知刷新 handler.sendEmptyMessage(UPDATA_VIDEO_NUM); } } }); //播放进度条事件 play_seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { //设置当前的播放时间 updataTimeFormat(current_time_tv, progress); if (videoView.getDuration() == progress) { play_controller_image.setImageResource(R.mipmap.video_play_blue); } } @Override public void onStartTrackingTouch(SeekBar seekBar) { //拖动视频进度时，停止刷新 handler.removeMessages(UPDATA_VIDEO_NUM); } @Override public void onStopTrackingTouch(SeekBar seekBar) { //停止拖动后，获取总进度 int totall = seekBar.getProgress(); //设置VideoView的播放进度 videoView.seekTo(totall); //重新handler刷新 handler.sendEmptyMessage(UPDATA_VIDEO_NUM); } }); //音量控制条事件 volume_seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { //设置音量变动后系统的值 audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,progress,0); } @Override public void onStartTrackingTouch(SeekBar seekBar) { } @Override public void onStopTrackingTouch(SeekBar seekBar) { } }); //设置全屏按钮点击事件 screen_image.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showLog("------当前屏幕标记----："+screen_flag); if(screen_flag){ setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//控制屏幕竖屏 }else { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//控制屏幕横屏 } } }); } @Override protected void initView() { videoView = (CustomVideoView) findViewById(R.id.main_video); videoLayout = (RelativeLayout) findViewById(R.id.act_testmovie_videolayout); controllerLayout = (LinearLayout) findViewById(R.id.main_controller_liner); play_seek = (SeekBar) findViewById(R.id.main_play_seek); volume_seek = (SeekBar) findViewById(R.id.main_volume_seek); current_time_tv = (TextView) findViewById(R.id.main_current_time); totally_time_tv = (TextView) findViewById(R.id.main_totally_time); play_controller_image = (ImageView) findViewById(R.id.play_pasue_image); screen_image = (ImageView) findViewById(R.id.main_screen_image); volume_Image = (ImageView) findViewById(R.id.act_testmovies_volume_image); DisplayMetrics metric = new DisplayMetrics(); screen_width = metric.widthPixels; screen_height = metric.heightPixels; } @Override protected void initData() { //获取设置音量的最大值 int volumeMax = audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC); volume_seek.setMax(volumeMax); //获取设置当前音量 int currentVolume = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC); volume_seek.setProgress(currentVolume); } }补上CustomVideoView public class CustomVideoView extends VideoView { //声明屏幕的大小 int width = 1920; int height = 1080; public CustomVideoView(Context context) { super(context); } public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } public CustomVideoView(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); //设置宽高 int defaultWidth = getDefaultSize(width,widthMeasureSpec); int defaultHeight = getDefaultSize(height,heightMeasureSpec); setMeasuredDimension(defaultWidth,defaultHeight); } }https://github.com/z1060932884/VideoDemo |
