GSYVideoPlayer播放器框架使用、播放元件原始碼探究（一）
在研究GSYVideoPlayer框架原始碼之前，先來探究一下如果如何使用框架提供的、基礎的視訊播器放元件類GSYVideoPlayer.java，通過層層封裝繼承，可以看出它也是繼承自FrameLayout這個幀佈局管理類，B站的IjkVideoPlayer視訊播放器元件的定義也是繼承自它。
開啟GSYVideoPlayer-master(官網例項demo)通過檢視標準的“簡單直接播放”按鈕對應的標準播放器元件StandardGSYVideoPlayer.java類，可看到下圖的繼承關係圖。
下面，為了便於分析播放器元件！為了便於分析播放器元件！為了便於分析播放器元件！重要的事情說三遍。我們的任務就是按照自定義元件的步驟流程，通過繼承框架提供的視訊播器放元件父類(GSYVideoPlayer.java)，來抄一份StandardGSYVideoPlayer.java原始碼樣例，我們對這個原始碼樣例StandardGSYVideoPlayer.java進行分型，為了和這個播放器元件區分，我們建立一個空類叫MyStandardGSYVideoPlayer.java，通過Alt+Enter組合鍵可以檢視繼承GSYVideoPlayer父類所必須實現的抽象方法，也是在下面這張圖中所示的：
MyStandardGSYVideoPlayer類如下：
由於這個類是一個自定義的播放器元件類，繼承了 GSYVideoPlayer.java類，所以需要重寫、實現父類GSYVideoPlayer中定義的一些抽象方法和介面方法，以及定義元件所必須提供的3個構造方法：
/* @author: LQS
* @date: 2020/12/15
* @description:
*/
class MyStandardGSYVideoPlayer extends GSYVideoPlayer {
/**
* 自定義元件的3個構造方法
* @param context
*/
public MyStandardGSYVideoPlayer(Context context) {
super(context);
}
public MyStandardGSYVideoPlayer(Context context, AttributeSet attrs) {
super(context, attrs);
}
public MyStandardGSYVideoPlayer(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
}可以看出主要的方法都是來自GSYVideoView和GSYVideoControlView,這兩個類。
下面就是從原始碼樣例類StandardGSYVideoPlayer.java類中複製程式碼到我們MyStandardGSYVideoPlayer.java類中去分析了。
首先第一大部分就是關於視訊播放元件關鍵的變數：
//亮度dialog
protected Dialog mBrightnessDialog;
//音量dialog
protected Dialog mVolumeDialog;
//觸控進度dialog
protected Dialog mProgressDialog;
//觸控進度條的progress
protected ProgressBar mDialogProgressBar;
//音量進度條的progress
protected ProgressBar mDialogVolumeProgressBar;
//亮度文字
protected TextView mBrightnessDialogTv;
//觸控移動顯示文字
protected TextView mDialogSeekTime;
//觸控移動顯示全部時間
protected TextView mDialogTotalTime;
//觸控移動方向icon
protected ImageView mDialogIcon;
protected Drawable mBottomProgressDrawable;
protected Drawable mBottomShowProgressDrawable;
protected Drawable mBottomShowProgressThumbDrawable;
protected Drawable mVolumeProgressDrawable;
protected Drawable mDialogProgressBarDrawable;
protected int mDialogProgressHighLightColor = -11;
protected int mDialogProgressNormalColor = -11;關鍵的都註釋了。
第二大部分就是關於視訊播放元件佈局初初始化方法：

*/
@Override
public int getLayoutId() {
return R.layout.video_layout_standard;
}
/**

protected int getBrightnessTextId() {

第三大部分就是關於視訊播放元件根據播放狀態顯示/隱藏UI按鈕方法：
這裡需要給出示意圖說明一下播放元件的螢幕組成結構：①頂部返回按鈕和視訊標題；②中部的播放/暫停按鈕、觸控滑動時的快進/快退圖示和進度條；③底部的當前播放點時間文字/視訊總時長和進度條；④以及最下面的視訊預載入進度條；
這裡面會有一個邏輯當點選螢幕時所有的UI按鈕、圖示、文字資訊和都會顯示，2.5秒之內再次點選螢幕，所有的UI按鈕、圖示、文字資訊會立即隱藏，若2.5秒之後不點選螢幕也會自動隱藏（這個後面會說），程式碼如下：
/********************************根據播放狀態控制UI顯示的方法*********************************************/
@Override
protected void changeUiToPlayingShow() {
Debuger.printfLog("changeUiToPlayingShow");
//頂部返回按鈕和標題根佈局
setViewShowState(mTopContainer, VISIBLE);
//底部播放時長文字和進度條、全屏按鈕的根佈局
setViewShowState(mBottomContainer, VISIBLE);
//螢幕中間區域開始、暫停按鈕
setViewShowState(mStartButton, VISIBLE);
//螢幕中心區域，和播放/暫停按鈕同一位置處的Loading載入中圖示，它是一個自定義的元件moe.codeest.enviews.ENDownloadView
setViewShowState(mLoadingProgressBar, INVISIBLE);
//視訊封面的父佈局，這個即使一個空的相對佈局
setViewShowState(mThumbImageViewLayout, INVISIBLE);
//底部進度調，應該是快取進度條
setViewShowState(mBottomProgressBar, INVISIBLE);
setViewShowState(mLockScreen, (mIfCurrentIsFullscreen && mNeedLockFull) ? VISIBLE : GONE);
if (mLoadingProgressBar instanceof ENDownloadView) {
((ENDownloadView) mLoadingProgressBar).reset();
}
updateStartImage();
}
/*下面的所有方法註釋不再給出，因為和上面播放時控制的變數都是一樣的，只不過顯示/隱藏值不同罷了
*/

localLayoutParams.x = location[0];
localLayoutParams.y = location[1];
mBrightnessDialog.getWindow().setAttributes(localLayoutParams);
}
if (!mBrightnessDialog.isShowing()) {
mBrightnessDialog.show();
}
if (mBrightnessDialogTv != null)
mBrightnessDialogTv.setText((int) (percent * 100) + "%");
}
@Override
protected void dismissBrightnessDialog() {
if (mBrightnessDialog != null) {
mBrightnessDialog.dismiss();
mBrightnessDialog = null;
}
}
@Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
dismissVolumeDialog();
dismissBrightnessDialog();
}
第六部分正常小屏--全屏--小屏進行切換時，需要將當前正在播放的資訊、樣式複製給將要使用的螢幕模式
/**
* 全屏-小屏-全屏相互切換時，將當前播放時間點、視訊時長、進度條百分比進度拷貝給播放器物件
* @param from
* @param to
*/
@Override
protected void cloneParams(GSYBaseVideoPlayer from, GSYBaseVideoPlayer to) {
super.cloneParams(from, to);
MyStandardGSYVideoPlayer sf = (MyStandardGSYVideoPlayer) from;
MyStandardGSYVideoPlayer st = (MyStandardGSYVideoPlayer) to;
if (st.mProgressBar != null && sf.mProgressBar != null) {
st.mProgressBar.setProgress(sf.mProgressBar.getProgress());
st.mProgressBar.setSecondaryProgress(sf.mProgressBar.getSecondaryProgress());
}
if (st.mTotalTimeTextView != null && sf.mTotalTimeTextView != null) {
st.mTotalTimeTextView.setText(sf.mTotalTimeTextView.getText());
}
if (st.mCurrentTimeTextView != null && sf.mCurrentTimeTextView != null) {
st.mCurrentTimeTextView.setText(sf.mCurrentTimeTextView.getText());
}
}
/**
* 將自定義的效果也設定到全屏
*
* @param context
* @param actionBar 是否有actionBar，有的話需要隱藏
* @param statusBar 是否有狀態bar，有的話需要隱藏
* @return
*/
@Override
public GSYBaseVideoPlayer startWindowFullscreen(Context context, boolean actionBar, boolean statusBar) {
GSYBaseVideoPlayer gsyBaseVideoPlayer = super.startWindowFullscreen(context, actionBar, statusBar);
if (gsyBaseVideoPlayer != null) {
MyStandardGSYVideoPlayer gsyVideoPlayer = (MyStandardGSYVideoPlayer) gsyBaseVideoPlayer;
gsyVideoPlayer.setLockClickListener(mLockClickListener);
gsyVideoPlayer.setNeedLockFull(isNeedLockFull());
initFullUI(gsyVideoPlayer);
//比如你自定義了返回案件，但是因為返回按鍵底層已經設定了返回事件，所以你需要在這裡重新增加的邏輯
}
return gsyBaseVideoPlayer;
}第七部分關於截圖功能：
/************************************* 關於截圖的 ****************************************/
/**
* 獲取截圖
*/
public void taskShotPic(GSYVideoShotListener gsyVideoShotListener) {
this.taskShotPic(gsyVideoShotListener, false);
}
/**
* 獲取截圖
*
* @param high 是否需要高清的
*/
public void taskShotPic(GSYVideoShotListener gsyVideoShotListener, boolean high) {
if (getCurrentPlayer().getRenderProxy() != null) {
getCurrentPlayer().getRenderProxy().taskShotPic(gsyVideoShotListener, high);
}
}
/**
* 儲存截圖
*/
public void saveFrame(final File file, GSYVideoShotSaveListener gsyVideoShotSaveListener) {
saveFrame(file, false, gsyVideoShotSaveListener);
}
/**
* 儲存截圖
*
* @param high 是否需要高清的
*/
public void saveFrame(final File file, final boolean high, final GSYVideoShotSaveListener gsyVideoShotSaveListener) {
if (getCurrentPlayer().getRenderProxy() != null) {
getCurrentPlayer().getRenderProxy().saveFrame(file, high, gsyVideoShotSaveListener);
}
}第八部分貼出開始播放的邏輯程式碼，這個比較少：
/**
* 開始播放
*/
@Override
public void startPlayLogic() {
if (mVideoAllCallBack != null) {
Debuger.printfLog("onClickStartThumb");
mVideoAllCallBack.onClickStartThumb(mOriginUrl, mTitle, MyStandardGSYVideoPlayer.this);
}
/**
* 父類GSYVideoControlView方法：增對列表優化，在播放前的時候才進行setup
* 優化內容：
* 設定播放URL
* @param url 播放url
* @param cacheWithPlay 是否邊播邊快取
* @param cachePath 快取路徑，如果是M3U8或者HLS，請設定為false
* @param mapHeadData 頭部資訊
* @param title title
*/
prepareVideo();
/**
* 開始對視訊播放元件上層的播放、暫停、播放進度條、播放時間/總時長等按鈕的顯示/隱藏進行控制
*
* protected int mDismissControlTime = 2500; 觸控顯示後隱藏的時間:觸控顯示控制按鈕，2.5秒後隱藏所有控制按鈕
* Runnable dismissControlTask = new Runnable(); 通過postDelayed()延時2.5秒後向訊息佇列傳送一個可執行的子執行緒訊息，去隱藏控制按鈕更新介面
*/
startDismissControlViewTimer();
}
/**
* 重新開啟進度查詢以及控制view消失的定時任務
* 用於解決GSYVideoHelper中通過removeview方式做全屏切換導致的定時任務停止的問題
* GSYVideoControlView onDetachedFromWindow（）
*/
public void restartTimerTask() {
startProgressTimer();
startDismissControlViewTimer();
}
好了到這裡原始碼樣例類StandardGSYVideoPlayer.java類的程式碼基本都分析完了 ，都在註釋裡，可以細細的品！
下面來說兩部分，自動隱藏播放介面上層的UI按鈕、圖示、文字資訊和通過手勢滑動控制音量Dialog、進度條Dialog、螢幕亮度Dialog的邏輯，鑑於篇幅過長，將總結到第二篇。
