Android 视频添加手势滑动调节亮度和音量以及更新进度

看公众号文章有一句话很有意思 . 人生 难以量化； 收获 静静等待。
直接上效果图
关于 Android 手势相关知识在此先不做太多的补充 ，等我忙完这一段时间之后来还这篇文章的技术债 。 Android 手势 当然是 GestureDetector 非他莫属 ，直接上代码 1.手势回调接口 public interface GenseePlayerListener { /** * 亮度手势，在View左半部区域上下滑动时候调用 * @param e1 * @param e2 * @param distanceX * @param distanceY */ public void onBrightnessGesture(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY); /** * 音量手势，在View右半部区域上下滑动时候调用 * @param e1 * @param e2 * @param distanceX * @param distanceY */ public void onVolumeGesture(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY); /** * 快进快退手势，在View左右滑动的时候调用 * @param e1 * @param e2 * @param distanceX * @param distanceY */ public void onVideoSpeedGesture(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY); /** * 打击手势 * @param e */ public void onSingleTapGesture(MotionEvent e); /** * 双击手势 * @param e */ public void onDoubleTapGesture(MotionEvent e); /** * 按下手势 * @param e */ public void onDown(MotionEvent e); /** * 快进快退执行后的松开时候调用 * @param e */ public void onVideoSpeedEnd(MotionEvent e); }2.自定义View public class GenseeTopFragment extends FrameLayout { private static final int NONE = 0, VOLUME = 1, BRIGHTNESS = 2, FF_REW = 3; private int mScrollMode = NONE; private GenseePlayOnGestureListener genseePlayOnGestureListener; private GestureDetector gestureDetector; private GenseePlayerListener genseePlayerListener; //横向偏移检测，让快进快退不那么敏感 private int offsetX = 1; private boolean videoSpeedEnd = false; public GenseeTopFragment(@NonNull Context context, @Nullable AttributeSet attrs) { super(context, attrs); init(context); } public GenseeTopFragment(@NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); init(context); } public GenseeTopFragment(@NonNull Context context) { super(context); init(context); } private void init(Context context) { genseePlayOnGestureListener = new GenseePlayOnGestureListener(); gestureDetector = new GestureDetector(context, genseePlayOnGestureListener); //取消长按，不然会影响滑动 gestureDetector.setIsLongpressEnabled(false); setOnTouchListener(new OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { if (event.getAction() == MotionEvent.ACTION_UP) { if (videoSpeedEnd) { if (genseePlayerListener != null) { genseePlayerListener.onVideoSpeedEnd(event); } videoSpeedEnd = false; } } //监听触摸事件 return gestureDetector.onTouchEvent(event); } }); } public void setGenseePlayerListener(GenseePlayerListener genseePlayerListener) { this.genseePlayerListener = genseePlayerListener; } /** * 拦截事件，禁止子View消费事件 */ @Override public boolean onInterceptTouchEvent(MotionEvent ev) { return true; } /** * 手势监听 */ public class GenseePlayOnGestureListener extends GestureDetector.SimpleOnGestureListener { @Override public boolean onDown(MotionEvent e) { videoSpeedEnd = false; //每次按下都重置为NONE mScrollMode = NONE; if (genseePlayerListener != null) { genseePlayerListener.onDown(e); } return true; } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { switch (mScrollMode) { case NONE: Log.i("AAAAAAA", "NONE: "); //offset是让快进快退不要那么敏感的值 if (Math.abs(distanceX) - Math.abs(distanceY) > offsetX) { mScrollMode = FF_REW; } else { if (e1.getX() < getWidth() / 2) { mScrollMode = BRIGHTNESS; } else { mScrollMode = VOLUME; } } break; case VOLUME: if (genseePlayerListener != null) { genseePlayerListener.onVolumeGesture(e1, e2, distanceX, distanceY); } Log.d("AAAAAAA", "VOLUME: "); break; case BRIGHTNESS: if (genseePlayerListener != null) { genseePlayerListener.onBrightnessGesture(e1, e2, distanceX, distanceY); } Log.d("AAAAAAA", "BRIGHTNESS: "); break; case FF_REW: if (genseePlayerListener != null) { genseePlayerListener.onVideoSpeedGesture(e1, e2, distanceX, distanceY); } videoSpeedEnd = true; Log.d("AAAAAAA", "FF_REW: "); break; } return true; } @Override public boolean onContextClick(MotionEvent e) { return super.onContextClick(e); } @Override public boolean onDoubleTap(MotionEvent e) { return super.onDoubleTap(e); } @Override public boolean onDoubleTapEvent(MotionEvent e) { return super.onDoubleTapEvent(e); } @Override public boolean onSingleTapUp(MotionEvent e) { return super.onSingleTapUp(e); } @Override public void onLongPress(MotionEvent e) { super.onLongPress(e); } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { return super.onFling(e1, e2, velocityX, velocityY); } @Override public void onShowPress(MotionEvent e) { super.onShowPress(e); } @Override public boolean onSingleTapConfirmed(MotionEvent e) { if (genseePlayerListener != null) { genseePlayerListener.onSingleTapGesture(e); } return super.onSingleTapConfirmed(e); } } }
PS：自定义VIew 有一个特殊功能禁止 子View 消费事件（跟手势滑动无关） 3.在Activity 使用 /**************************手势监听*****************************/ private int newProgress = 0, oldProgress = 0; private int oldVolume = 0; private int maxVolume = 0; private float brightness = 1; private BrightnessHelper mBrightnessHelper; private AudioManager mAudioManager; private Window mWindow; private WindowManager.LayoutParams mLayoutParams; private ChangeBarView changeBarView;// 音量/亮度 @Override public void onDown(MotionEvent e) { //每次按下的时候更新当前亮度和音量，还有进度 oldProgress = newProgress; oldVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC); brightness = mLayoutParams.screenBrightness; if (brightness == -1) { //一开始是默认亮度的时候，获取系统亮度，计算比例值 brightness = mBrightnessHelper.getBrightness() / 255f; } } @Override public void onBrightnessGesture(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { //下面这是设置当前APP亮度的方法 Log.d(TAG, "onBrightnessGesture: old" + brightness); float newBrightness = (e1.getY() - e2.getY()) / fl_big_layout.getHeight(); newBrightness += brightness; if (newBrightness < 0) { newBrightness = 0; } else if (newBrightness > 1) { newBrightness = 1; } mLayoutParams.screenBrightness = newBrightness; mWindow.setAttributes(mLayoutParams); changeBarView.showInfo((int) (newBrightness * 100), false); } @Override public void onVolumeGesture(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { int value = fl_big_layout.getHeight() / maxVolume; int newVolume = (int) ((e1.getY() - e2.getY()) / value + oldVolume); mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, newVolume, AudioManager.FLAG_PLAY_SOUND); if (newVolume < 0) { newVolume = 0; } //要强行转Float类型才能算出小数点，不然结果一直为0 int volumeProgress = (int) (newVolume / Float.valueOf(maxVolume) * 100); if (volumeProgress > 100) { volumeProgress = 100; } changeBarView.showInfo(volumeProgress, true); } @Override public void onVideoSpeedGesture(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { } @Override public void onSingleTapGesture(MotionEvent e) { hideController(isGoneView); } @Override public void onDoubleTapGesture(MotionEvent e) { } @Override public void onVideoSpeedEnd(MotionEvent e) { }
PS：只是简单地进行复制代码 ，保证可以使用 。 稍等我在上传 demo 。
