下面說說android的事把

最近是不是也會遇到需求中需要用到錄屏錄音的功能,最近也是遇到的 現在整理完記錄一下

首先呢,錄音錄屏需要權限 先貼一個動態權限類

public class TalAllow { /** * RECORD_AUDIO 音頻權限 * WRITE_EXTERNAL_STORAGE 寫入權限 * CAMERA相機權限 */ public static void requestPermissions(Context context,int allowCode) { ArrayList<String> ps = new ArrayList<>(); int per = ContextCompat.checkSelfPermission(context, Manifest.permission.RECORD_AUDIO); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.RECORD_AUDIO); } per = ContextCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.WRITE_EXTERNAL_STORAGE); } per = ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.CAMERA); } per = ContextCompat.checkSelfPermission(context, Manifest.permission.READ_PHONE_STATE); if (per != PackageManager.PERMISSION_GRANTED) { ps.add(Manifest.permission.READ_PHONE_STATE); } Log.d(TAG, 'requestPermissions:ps=' + ps.size()); if (!ps.isEmpty()) { String[] ps3 = new String[ps.size()]; ps.toArray(ps3); ActivityCompat.requestPermissions((Activity) context, ps3, allowCode); } }}

有需求需要判斷權限的呢 插入個鏈接 （上面那個類code碼為100）判斷是否有權限

下面重點來了

首先說明一下這個錄屏和錄音是在服務里面做的，所以呢貼一個服務類這個代碼絕對有質量 做了很多處理,下面一行一行解讀把

//首先呢實現的是Handle.Callback接口 主要是做時間及計時時間回調的,會重新寫HandleMessage方法,其實我個覺得跟在括號{} 里面重寫沒啥區別就是簡潔頁面public class TalScreenRecordService extends Service implements Handler.Callback {//這個就不解釋了吧 log private static final String TAG = 'TalScreenRecordService'; //這個類是管理類拿到服務后會通過下面的類申請錄屏,點擊允許， //其中會回調兩個參數,code碼 和 data,都在ActivityForResult中進行判斷code private MediaProjectionManager mProjectionManager; //這個會拿到申請的結果 private MediaProjection mMediaProjection; //這個類就是我們主要的錄屏錄音的類啦 private MediaRecorder mMediaRecorder; //這個就是我們要獲取錄制屏幕的大小,像素,等等一些數據 //關于這類更詳細的介紹https://blog.csdn.net/qq_16628781/article/details/62038163 private VirtualDisplay mVirtualDisplay; //是否正在錄制 false 沒有錄制 private boolean mIsRunning; //獲取屏幕的寬高和像素密度 稍后貼類 private int mRecordWidth = TalScreenParams.getScreenWidth(); private int mRecordHeight = TalScreenParams.getScreenWidth(); private int mScreenDpi = TalScreenParams.getScreenDpi(); //code data 就是上面說的允許后回調 private int mResultCode; private Intent mResultData; //錄屏文件的保存地址 private String mRecordFilePath; private Handler mHandler; //已經錄制多少秒了 private int mRecordSeconds = 0; //handle發送消息時的what private static final int MSG_TYPE_COUNT_DOWN = 110; //這個是繼承Service 必須重寫的方法 這是使用的BindService(生命周期的長短跟activity一致) @Override public IBinder onBind(Intent intent) { return new RecordBinder(); } //說一說這個返回值的問題吧 // START_STICKY 粘性返回 ,一次失敗,多次啟動,不保留Intent對象 //關于返回值問題https://blog.csdn.net/github_37663523/article/details/78811539 @Override public int onStartCommand(Intent intent, int flags, int startId) { return START_STICKY;

if (mMediaRecorder != null) { mMediaRecorder.reset(); mMediaRecorder.release(); mMediaRecorder = null; } mResultData = null; //不執行的時候false mIsRunning = false; } //這個就是給是否正在錄屏提供一個get方法 public boolean ismIsRunning() { return mIsRunning; } //這個就是設置數據的方法在ActivityForResult中設置數據,說明是允許錄屏的 @TargetApi(Build.VERSION_CODES.LOLLIPOP) public void setResultData(int resultCode, Intent resultData) { mResultCode = resultCode; mResultData = resultData; //拿到這個管理,看不懂跟上面注釋結合看 mProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE); //getMediaProjection(code,data)不知道這樣寫看不看的董 //說白了MediaProjectionManager是申請權限 MediaProjection是獲取申請結果,防止別人調取隱私 //再通過上面的setResultData方法獲取到ActivityForResult中的code,data if (mProjectionManager != null) { mMediaProjection = mProjectionManager.getMediaProjection(mResultCode, mResultData); } } //開始錄制了 @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP) public boolean startRecord() { //代碼執行順序(false,目前沒錄屏) if (mIsRunning) { return false; } //再次創建,防止異常 if (mMediaProjection == null) { mMediaProjection = mProjectionManager.getMediaProjection(mResultCode, mResultData); } //關于文件路徑還有錄屏的一些參數問題 setUpMediaRecorder(); //關于獲取錄制屏幕的大小,像素,等等一些數據 createVirtualDisplay(); //開始錄制 mMediaRecorder.start(); //稍后貼類 監聽錄制情況 TalScreenUtils.startRecord(); //最多錄制三分鐘 mHandler.sendEmptyMessageDelayed(MSG_TYPE_COUNT_DOWN, 1000);

下面貼關于手機像素還有dpi的類

public class TalScreenParams { private static int mScreenWidth; private static int mScreenHeight; private static int mScreenDpi; public static void init(Activity activity){ Display display = activity.getWindowManager().getDefaultDisplay(); DisplayMetrics metrics = new DisplayMetrics(); display.getMetrics(metrics); mScreenWidth = metrics.widthPixels; mScreenHeight = metrics.heightPixels; mScreenDpi = metrics.densityDpi; } public static int getScreenWidth(){ return mScreenWidth; } public static int getScreenHeight(){ return mScreenHeight; } public static int getScreenDpi(){ return mScreenDpi; }

下面貼關于刪除文件,添加到媒體庫的類 這里就使用到了ContentResolver

public class TalFileUtils { /** * 刪除SD卡中的文件或目錄 * * @param path * @return */ public static boolean deleteSDFile(String path) { return deleteSDFile(path, false); } /** * 刪除SD卡中的文件或目錄 * * @param path * @param deleteParent true為刪除父目錄 * @return */ public static boolean deleteSDFile(String path, boolean deleteParent) { if (TextUtils.isEmpty(path)) { return false; } File file = new File(path); if (!file.exists()) { //不存在 return true; } return deleteFile(file, deleteParent); } /** * @param file * @param deleteParent true為刪除父目錄 * @return */ public static boolean deleteFile(File file, boolean deleteParent) { boolean flag = false; if (file == null) { return flag; } if (file.isDirectory()) { //是文件夾 File[] files = file.listFiles(); if (files.length > 0) {for (int i = 0; i < files.length; i++) { flag = deleteFile(files[i], true); if (!flag) { return flag; }} } if (deleteParent) {flag = file.delete(); } } else { flag = file.delete(); } file = null; return flag; } /** * 添加到媒體數據庫 * * @param context 上下文 */ public static Uri fileScanVideo(Context context, String videoPath, int videoWidth, int videoHeight, int videoTime) { File file = new File(videoPath); if (file.exists()) { Uri uri = null; long size = file.length(); String fileName = file.getName(); long dateTaken = System.currentTimeMillis(); ContentValues values = new ContentValues(11); values.put(MediaStore.Video.Media.DATA, videoPath); // 路徑; values.put(MediaStore.Video.Media.TITLE, fileName); // 標題; values.put(MediaStore.Video.Media.DURATION, videoTime * 1000); // 時長 values.put(MediaStore.Video.Media.WIDTH, videoWidth); // 視頻寬 values.put(MediaStore.Video.Media.HEIGHT, videoHeight); // 視頻高 values.put(MediaStore.Video.Media.SIZE, size); // 視頻大小; values.put(MediaStore.Video.Media.DATE_TAKEN, dateTaken); // 插入時間; values.put(MediaStore.Video.Media.DISPLAY_NAME, fileName);// 文件名; values.put(MediaStore.Video.Media.DATE_MODIFIED, dateTaken / 1000);// 修改時間; values.put(MediaStore.Video.Media.DATE_ADDED, dateTaken / 1000); // 添加時間; values.put(MediaStore.Video.Media.MIME_TYPE, 'video/mp4'); ContentResolver resolver = context.getContentResolver(); if (resolver != null) {try { uri = resolver.insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);} catch (Exception e) { e.printStackTrace(); uri = null;} } if (uri == null) {MediaScannerConnection.scanFile(context, new String[]{videoPath}, new String[]{'video/*'}, new MediaScannerConnection.OnScanCompletedListener() { @Override public void onScanCompleted(String path, Uri uri) { }}); } return uri; } return null; } /** * SD卡存在并可以使用 */ public static boolean isSDExists() { return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED); } /** * 獲取SD卡的剩余容量，單位是Byte * * @return */ public static long getSDFreeMemory() { try { if (isSDExists()) {File pathFile = Environment.getExternalStorageDirectory();// Retrieve overall information about the space on a filesystem.// This is a Wrapper for Unix statfs().StatFs statfs = new StatFs(pathFile.getPath());// 獲取SDCard上每一個block的SIZElong nBlockSize = statfs.getBlockSize();// 獲取可供程序使用的Block的數量// long nAvailBlock = statfs.getAvailableBlocksLong();long nAvailBlock = statfs.getAvailableBlocks();// 計算SDCard剩余大小Bytelong nSDFreeSize = nAvailBlock * nBlockSize;return nSDFreeSize; } } catch (Exception ex) { ex.printStackTrace(); } return 0; } public static long getFreeMem(Context context) { ActivityManager manager = (ActivityManager) context.getApplicationContext().getSystemService(Activity.ACTIVITY_SERVICE); if (manager != null) { ActivityManager.MemoryInfo info = new ActivityManager.MemoryInfo(); if (info != null) {manager.getMemoryInfo(info);// 單位Bytereturn info.availMem / 1024 / 1024; } } return 0; }}

還有一個類 是為整個Service提供了便捷訪問的類 ，將一些監聽service中的變化放到集合里來做

public class TalScreenUtils { private static TalScreenRecordService s_ScreenRecordService; private static List<RecordListener> s_RecordListener = new ArrayList<>(); private static List<OnPageRecordListener> s_PageRecordListener = new ArrayList<>(); //true,錄制結束的提示語正在顯示 public static boolean s_IsRecordingTipShowing = false; /** * 錄屏功能 5.0+ 的手機才能使用 * @return */ public static boolean isScreenRecordEnable(){ return Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ; } public static void setScreenService(TalScreenRecordService screenService){ s_ScreenRecordService = screenService; } public static void clear(){ if ( isScreenRecordEnable() && s_ScreenRecordService != null){ s_ScreenRecordService.clearAll(); s_ScreenRecordService = null; } if (s_RecordListener != null && s_RecordListener.size() > 0){ s_RecordListener.clear(); } if (s_PageRecordListener != null && s_PageRecordListener.size() > 0 ){ s_PageRecordListener.clear(); } } /** * 開始錄制 */ public static void startScreenRecord(Activity activity, int requestCode) { if (isScreenRecordEnable()){ if (s_ScreenRecordService != null && !s_ScreenRecordService.ismIsRunning()){if (!s_ScreenRecordService.isReady()){ MediaProjectionManager mediaProjectionManager = (MediaProjectionManager) activity. getSystemService(Context.MEDIA_PROJECTION_SERVICE); if (mediaProjectionManager != null){ Intent intent = mediaProjectionManager.createScreenCaptureIntent(); PackageManager packageManager = activity.getPackageManager(); if (packageManager.resolveActivity(intent,PackageManager.MATCH_DEFAULT_ONLY) != null){ //存在錄屏授權的Activity activity.startActivityForResult(intent,requestCode); }else { Toast.makeText(activity, '不能錄音', Toast.LENGTH_SHORT).show(); } }} else { s_ScreenRecordService.startRecord();} } } } /** * 獲取用戶允許錄屏后，設置必要的數據 * @param resultCode * @param resultData */ public static void setUpData(int resultCode,Intent resultData) throws Exception{ if (isScreenRecordEnable()){ if (s_ScreenRecordService != null && !s_ScreenRecordService.ismIsRunning()){s_ScreenRecordService.setResultData(resultCode,resultData);s_ScreenRecordService.startRecord(); } } } /** * 停止錄制 */ public static void stopScreenRecord(Context context){ if (isScreenRecordEnable()){ if (s_ScreenRecordService != null && s_ScreenRecordService.ismIsRunning()){String str = '停止錄制';s_ScreenRecordService.stopRecord(str); } } } /** * 獲取錄制后的文件地址 * @return */ public static String getScreenRecordFilePath(){ if (isScreenRecordEnable() && s_ScreenRecordService!= null) { return s_ScreenRecordService.getRecordFilePath(); } return null; } /** * 判斷當前是否在錄制 * @return */ public static boolean isCurrentRecording(){ if (isScreenRecordEnable() && s_ScreenRecordService!= null) { return s_ScreenRecordService.ismIsRunning(); } return false; } /** * true,錄制結束的提示語正在顯示 * @return */ public static boolean isRecodingTipShow(){ return s_IsRecordingTipShowing; } public static void setRecordingStatus(boolean isShow){ s_IsRecordingTipShowing = isShow; } /** * 系統正在錄屏，app 錄屏會有沖突，清理掉一些數據 */ public static void clearRecordElement(){ if (isScreenRecordEnable()){ if (s_ScreenRecordService != null ){s_ScreenRecordService.clearRecordElement(); } } } public static void addRecordListener(RecordListener listener){ if (listener != null && !s_RecordListener.contains(listener)){ s_RecordListener.add(listener); } } public static void removeRecordListener(RecordListener listener){ if (listener != null && s_RecordListener.contains(listener)){ s_RecordListener.remove(listener); } } public static void addPageRecordListener( OnPageRecordListener listener){ if (listener != null && !s_PageRecordListener.contains(listener)){ s_PageRecordListener.add(listener); } } public static void removePageRecordListener( OnPageRecordListener listener){ if (listener != null && s_PageRecordListener.contains(listener)){ s_PageRecordListener.remove(listener); } } public static void onPageRecordStart(){ if (s_PageRecordListener!= null && s_PageRecordListener.size() > 0 ){ for (OnPageRecordListener listener : s_PageRecordListener){listener.onStartRecord(); } } } public static void onPageRecordStop(){ if (s_PageRecordListener!= null && s_PageRecordListener.size() > 0 ){ for (OnPageRecordListener listener : s_PageRecordListener){listener.onStopRecord();

} } } public static void startRecord(){ if (s_RecordListener.size() > 0 ){ for (RecordListener listener : s_RecordListener){listener.onStartRecord();Log.i('xxx', 'startRecord: '); } } } public static void pauseRecord(){ if (s_RecordListener.size() > 0 ){ for (RecordListener listener : s_RecordListener){listener.onPauseRecord(); } } } public static void resumeRecord(){ if (s_RecordListener.size() > 0 ){ for (RecordListener listener : s_RecordListener){listener.onResumeRecord(); } } } public static void onRecording(String timeTip){ if (s_RecordListener.size() > 0 ){ for (RecordListener listener : s_RecordListener){listener.onRecording(timeTip); } } } public static void stopRecord(String stopTip){ if (s_RecordListener.size() > 0 ){ for (RecordListener listener : s_RecordListener){listener.onStopRecord( stopTip); } } } public interface RecordListener{ void onStartRecord(); void onPauseRecord(); void onResumeRecord(); void onStopRecord(String stopTip); void onRecording(String timeTip); } public interface OnPageRecordListener { void onStartRecord(); void onStopRecord(); void onBeforeShowAnim(); void onAfterHideAnim(); }}

到了最后了,是一些調用時的內容

public class MainActivity extends AppCompatActivity { private static final String TAG = MainActivity.class.getSimpleName(); private Button mBtn; private final int REQUEST_ALLOW = 100; private Button mButton; //bindService需要創建連接 private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { //啟動service TalScreenRecordService.RecordBinder recordBinder = (TalScreenRecordService.RecordBinder) service; TalScreenRecordService recordService = recordBinder.getRecordService(); //這個其實是傳值在使用的activity中拿到Service TalScreenUtils.setScreenService(recordService); } @Override public void onServiceDisconnected(ComponentName name) { } }; //開啟service,意圖跳轉到service,別忘了AndroidManifest里面需要注冊這個service哦 private void startService() { Intent intent = new Intent(MainActivity.this, TalScreenRecordService.class); bindService(intent, mConnection, BIND_AUTO_CREATE); } @Override protected void onCreate(final Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mBtn = findViewById(R.id.btn); mButton = findViewById(R.id.button2); initView(); //兩個按鈕 一個開始 一個結束 xml不貼了 mBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {if (TalFileUtils.getFreeMem(MainActivity.this) < 100) { Toast.makeText(MainActivity.this, '手機內存不足,請清理后再進行錄屏', Toast.LENGTH_SHORT).show(); return;}//開始錄屏錄音TalScreenUtils.startScreenRecord(MainActivity.this, REQUEST_ALLOW); } }); mButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) {stop();Log.i(TAG, 'onClick: ' + stop()); } //停止錄屏錄音返回路徑 private String stop() {TalScreenUtils.stopScreenRecord(MainActivity.this);//停止return TalScreenUtils.getScreenRecordFilePath(); } }); } @Override protected void onStart() { super.onStart(); } private void initView() { //權限申請 TalAllow.requestPermissions(this, REQUEST_ALLOW); //獲取屏幕大小 在onCreate里面初始化就可以獲取 TalScreenParams.init(this); startService(); } @Override protected void onStop() { super.onStop(); //在對用戶可見不可交互的時候防止異常 TalScreenUtils.clear(); } //打印權限獲取情況日志 @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { Toast.makeText(this, permissions[0] + 'n' + grantResults[0], Toast.LENGTH_SHORT).show(); super.onRequestPermissionsResult(requestCode, permissions, grantResults); } //在用戶允許錄屏后拿到確定的code 跟data @Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { super.onActivityResult(requestCode, resultCode, data); if (requestCode == REQUEST_ALLOW && data != null) { try { //設置數據，在用戶允許后 調用了開始錄屏的方法TalScreenUtils.setUpData(resultCode, data);//拿到路徑String screenRecordFilePath = TalScreenUtils.getScreenRecordFilePath();if (screenRecordFilePath == null) { Toast.makeText(this, '空的', Toast.LENGTH_SHORT).show();}Toast.makeText(MainActivity.this, '' + screenRecordFilePath, Toast.LENGTH_SHORT).show();Log.i('zlq', 'onClick: ' + screenRecordFilePath); } catch (Exception e) {e.printStackTrace(); } } else { Toast.makeText(this, '禁止錄屏', Toast.LENGTH_SHORT).show(); } } @Override protected void onDestroy() { super.onDestroy(); unbindService(mConnection); }}

至此，一個還算比較完整的錄屏錄音功能就可以實現,不足之處請批評指正
