本文實例為大家分享了VideoView原生自定義視頻播放器的具體代碼，供大家參考，具體內容如下
項目用到的技術點和亮點
- VideoView封裝視頻播放工具類
- 自定義視頻控制面板
- 手勢識別器的使用
1. VideoView封裝視頻播放工具類
視頻播放這些其實都挺簡單的，VideoView這個類都提供了相應方法，詳細見代碼 代碼都比較簡單，不過需要注意的是要在主線程中更新視頻面板的UI信息。

//1. 創建手勢識別器 progressGestureDetector = new GestureDetector(mContext,new ProgressGestureListenr());//2.復寫GestureDetector.OnGestureListener的6個方法boolean onDown(MotionEvent e) //用戶按下屏幕就會觸發void onShowPress(MotionEvent e) ////down事件發生而move或則up還沒發生前觸發該事件boolean onSingleTapUp(MotionEvent e) //一次點擊up事件boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) //在屏幕上拖動事件void onLongPress(MotionEvent e) //長按事件 boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) //滑動手勢事件 //3 onTouch中攔截 @Override public boolean onTouch(View view, MotionEvent event) { return progressGestureDetector.onTouchEvent(event); } //4 事件綁定 progressArea.setOnTouchListener(this); |
3. 自定義視頻控制面板
代碼比較簡單同時代碼不長 都有注釋 需要的可以參考下 大神勿噴
