自定义视频播放器

前言

这段时间公司要做视频播放的项目，之前没有任何这方面的相关经验，经过多方查阅写出来一个demo，相对而言还是比较完整的，在这边记录一下，顺便能够帮助更多的人来学习视频的播放，也顺便作为自己的一个笔记。

首先看一下效果图：

1.首先要在SDCard中放置一个视频文件（咱们示例本地的视频播放）

String path = Environment.getExternalStorageDirectory().getAbsolutePath()+"/cjyx.mp4";

2.由于使用源生的VideoView在播放的时候，屏幕会出现空白的情况，为了从新测量屏幕的尺寸我们自定义一个VideoView，其实就是重写onMeasure()方法。

/** * @author :huangxianfeng on 2017/3/9. * 自定义一个VideoView */ public class CustomVideoView extends VideoView{ int defaultWidth = 1920; int defaultHeight = 1080; public CustomVideoView(Context context) { super(context); } public CustomVideoView(Context context, AttributeSet attrs) { super(context, attrs); } public CustomVideoView(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } /** * 测量方法 * 作用是强行设置他的宽度和高度 * @param widthMeasureSpec * @param heightMeasureSpec */ @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); int width = getDefaultSize(defaultWidth,widthMeasureSpec); int height = getDefaultSize(defaultHeight,heightMeasureSpec); setMeasuredDimension(width, height); } }

3.由于我们在改变屏幕的亮度和改变音量的大小，我们要根据手势在屏幕上的滑动距离来判断，所以我要拿到屏幕的尺寸、音量、和亮度的最大值和当前值。

/** * 获取的当前的屏幕的宽度和高度 */ screen_width = getResources().getDisplayMetrics().widthPixels; screen_hright = getResources().getDisplayMetrics().heightPixels; /** * 当前设备的最大音量 */ int streamMaxVolume = mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC); /** * 获取设备的当前音量 */ int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); //屏幕的当前亮度 WindowManager.LayoutParams attributes = getWindow().getAttributes(); mBrightness = attributes.screenBrightness;//当前的亮度

4.视频播放我们避免不了会横屏播放视频，那么在播放时，会遇到从竖屏变换到横屏的时候，每次视频都会从头开始播放，因为在横竖屏切换的时候，系统把Activity给销毁了，并创建了一个新的Activity播放导致。

但在Manifest.xml中注册Activity的时，添加属性：

android:configChanges="orientation|screenSize|keyboard|keyboardHidden"

即可避免Activity的销毁。

但仅仅是上面的那些还是不够的，我们接下来要监听横竖屏的改变，当屏幕发生改变的时候，我们进行相对于的屏幕设置：

/** * 1.此系统方法是监听屏幕的改变 * 监听到屏幕的方向的改变 * @param newConfig */ @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); /** * 当屏幕方向为横屏的时候 */ if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){ setVideoViewScale(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT); volume_img.setVisibility(View.VISIBLE); volume_seek.setVisibility(View.VISIBLE); isFullScreen = true; //移出半屏的状态 getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); //设置全屏 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); }else{//为竖屏的时候 setVideoViewScale(ViewGroup.LayoutParams.MATCH_PARENT, ScreenUtil.getInstance().px2Dp(MainActivity.this, 240)); volume_img.setVisibility(View.GONE); volume_seek.setVisibility(View.GONE); isFullScreen = false; //设置全屏 getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); //移出半屏的状态 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); } }

5.如效果图所示，左下角有一个播放进度时间，还一个总时间，实现方法的计算如下代码：

/** * 时间格式的转换 并设置播放时间和总时间 * @param textview * @param millsecond */ private void updateTextViewWithTimeFormat(TextView textview,int millsecond){ int second = millsecond/1000; int hh = second/3600;//小时 int mm = second%3600/60;//分钟 int ss = second%60;//秒 String str = null; if (hh!=0){ str = String.format("d:d:d",hh,mm,ss); }else{ str = String.format("d:d",mm,ss); } textview.setText(str); }

上面代码还要依赖一个对屏幕宽度和高度重新赋值的方法：

/** * 对屏幕宽度和高度从新赋值 * @param width * @param height */ private void setVideoViewScale(int width,int height){ ViewGroup.LayoutParams layoutParams = mVideoView.getLayoutParams(); layoutParams.width = width; layoutParams.height = height; mVideoView.setLayoutParams(layoutParams); ViewGroup.LayoutParams layoutParams1 = videoLayout.getLayoutParams(); layoutParams1.width = width; layoutParams1.height = height; videoLayout.setLayoutParams(layoutParams1); }

6.在不断更新时间变换时，我们采用Handler自己更新自己的方式，来实现时间进度的变换：

/** * 实时更新视频的时间 */ private Handler UIHandler = new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); if (msg.what == UPDATEUI) { //获取视频当前的播放时间 int currentPosition = mVideoView.getCurrentPosition(); //获取视频播放的总时间 int totalDuration = mVideoView.getDuration(); //格式化视频播放时间 updateTextViewWithTimeFormat(tiem_current_tv,currentPosition); updateTextViewWithTimeFormat(time_total_tv,totalDuration); //设置视频总时间 play_seek.setMax(totalDuration); play_seek.setProgress(currentPosition); //自己更新自己来实现UI时间界面的更新 UIHandler.sendEmptyMessageDelayed(UPDATEUI,500); } } };

7.然后播放进度时，我们可以通过对SeekBar的监听，来拖动视频的播放进度：

/** * Seekbar设置监听事件 */ play_seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { updateTextViewWithTimeFormat(tiem_current_tv, progress); } @Override public void onStartTrackingTouch(SeekBar seekBar) { UIHandler.removeMessages(UPDATEUI); } @Override public void onStopTrackingTouch(SeekBar seekBar) { int progress = seekBar.getProgress(); //另视频播放的进度遵循SeekBar停止拖动的这一刻进度 mVideoView.seekTo(progress); UIHandler.sendEmptyMessage(UPDATEUI); } });

8.如上我们获取到了屏幕亮度和音量的大小接下来我们就可以根据对VideoView的手势监听setOnTouchListener来控制亮度和音量：

/** * 控制VideoView的手势事件 */ mVideoView.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { float x = event.getX(); float y = event.getY(); Log.e("Main", "x=" + x + ";y=" + y); // float lastX=0, lastY=0; switch (event.getAction()) { /** * 手指落下屏幕的那一刻调用（只调用一次） */ case MotionEvent.ACTION_DOWN: lastX = x; lastY = y; break; /** * 手指在屏幕上移动（调用多次） */ case MotionEvent.ACTION_MOVE: //计算偏移量 float detlaX = x - lastX; float detlaY = y - lastY; //计算滑动时x轴和y轴的偏移量的绝对值 float absdetlaX = Math.abs(detlaX); float absdetlaY = Math.abs(detlaY); //滑动的绝对值与之前设定的临界值进行比较 if (absdetlaX > threshold && absdetlaY > threshold) { if (absdetlaX < absdetlaY) {//y轴大于x轴的滑动，滑动是有效的 isAdjust = true; } else { isAdjust = false; } } else if (absdetlaX < threshold && absdetlaY > threshold) { isAdjust = true; } else if (absdetlaX > threshold && absdetlaY < threshold) { isAdjust = false; } Log.e("Main", "手势是否合法" + isAdjust); if (isAdjust) { /** * 在判断当前手势是否和发的情况下，去区分此时的手势是调节亮度还是调节音量 */ if (x < screen_width / 2) { /** * 调节亮度 */ // if (detlaY > 0) { // /** // * 降低亮度 // */ Log.e("Main", "降低亮度" + detlaY); // } else { // /** // * 升高亮度 // */ Log.e("Main", "升高亮度" + detlaY); // } changeBrightness(-detlaY); } else { // /** // * 调节音量 // */ // if (detlaY > 0) { // /** // * 减小音量 // */ Log.e("Main", "减小音量" + detlaY); // } else { // /** // * 增加音量 // */ Log.e("Main", "增加音量" + detlaY); // } changeVolume(-detlaY); } } lastX = x; lastY = y; break; /** * 手指离开屏幕的那一刻（调用一次） */ case MotionEvent.ACTION_UP: //抬起的时候进行对调节亮度的和音量的图标进行隐藏 progress_layout.setVisibility(View.GONE); break; } return true; } });

根据手势判断出用户左屏幕和右屏幕，再判断出上滑还是下滑来实现音量的改变（此方法包含音量图标的显示和隐藏）：

/** * 改变音量 */ private void changeVolume(float detlaY){ //最大 int max = mAudioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC); //当前音量 int current = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); int index = (int)(detlaY/screen_hright*max*3); int volume =Math.max(current + index, 0); mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, volume, 0); //当处于隐藏状态的时候，进行显示 if (progress_layout.getVisibility() == View.GONE){ progress_layout.setVisibility(View.VISIBLE); } /** * 1.设置音量图标的显示 * 2.并且从新进行参数的设置 */ operation_bg.setImageResource(R.drawable.video_volume_bg); ViewGroup.LayoutParams layoutParams = operation_percent.getLayoutParams(); layoutParams.width = (int) (ScreenUtil.getInstance().dp2Px(MainActivity.this,94)*(float)volume/max); operation_percent.setLayoutParams(layoutParams); volume_seek.setProgress(volume); }

根据手势判断出用户左屏幕和右屏幕，再判断出上滑还是下滑来实现亮度的改变（此方法包含亮度图标的显示和隐藏）：

/** * 改变屏幕的显示亮度 * @param detlaY */ private void changeBrightness(float detlaY){ WindowManager.LayoutParams attributes = getWindow().getAttributes(); mBrightness = attributes.screenBrightness;//当前的亮度 float index = detlaY/screen_hright/3; mBrightness +=index; if (mBrightness > 1.0f){ mBrightness= 1.0f; } if (mBrightness < 0.01f){ mBrightness= 0.01f; } attributes.screenBrightness = mBrightness; //当处于隐藏状态的时候，进行显示 if (progress_layout.getVisibility() == View.GONE){ progress_layout.setVisibility(View.VISIBLE); } /** * 1.设置亮度图标的显示 * 2.并且从新进行参数的设置 */ operation_bg.setImageResource(R.drawable.video_brightness_bg); ViewGroup.LayoutParams layoutParams = operation_percent.getLayoutParams(); layoutParams.width = (int) (ScreenUtil.getInstance().dp2Px(MainActivity.this,94)*mBrightness); operation_percent.setLayoutParams(layoutParams); getWindow().setAttributes(attributes); }
