Android仿微信拍攝短視頻_Android

近期做項目需要添加上傳短視頻功能，功能設定為類似於微信，點擊開始拍攝，設定最長拍攝時間，經過研究最終實現了這個功能，下面就和大家分享一下，希望對你有協助。

1.視頻錄製自訂控制項：

/** * 視頻播放控制項 */public class MovieRecorderView extends LinearLayout implements OnErrorListener { private SurfaceView mSurfaceView; private SurfaceHolder mSurfaceHolder; private ProgressBar mProgressBar; private MediaRecorder mMediaRecorder; private Camera mCamera; private Timer mTimer;// 計時器 private OnRecordFinishListener mOnRecordFinishListener;// 錄製完成回調介面 private int mWidth;// 視頻解析度寬度 private int mHeight;// 視頻解析度高度 private boolean isOpenCamera;// 是否一開始就開啟網路攝影機 private int mRecordMaxTime;// 一次拍攝最長時間 private int mTimeCount;// 時間計數 private File mVecordFile = null;// 檔案 public MovieRecorderView(Context context) { this(context, null); } public MovieRecorderView(Context context, AttributeSet attrs) { this(context, attrs, 0); } @SuppressLint("NewApi") public MovieRecorderView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); TypedArray a = context.obtainStyledAttributes(attrs,  R.styleable.MovieRecorderView, defStyle, 0); mWidth = a.getInteger(R.styleable.MovieRecorderView_width, 320);// 預設320 mHeight = a.getInteger(R.styleable.MovieRecorderView_height, 240);// 預設240 isOpenCamera = a.getBoolean( R.styleable.MovieRecorderView_is_open_camera, true);// 預設開啟 mRecordMaxTime = a.getInteger( R.styleable.MovieRecorderView_record_max_time, 10);// 預設為10 LayoutInflater.from(context)  .inflate(R.layout.movie_recorder_view, this); mSurfaceView = (SurfaceView) findViewById(R.id.surfaceview); mProgressBar = (ProgressBar) findViewById(R.id.progressBar); mProgressBar.setMax(mRecordMaxTime);// 設定進度條最大量 mSurfaceHolder = mSurfaceView.getHolder(); mSurfaceHolder.addCallback(new CustomCallBack()); mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); a.recycle(); } /** *  */ private class CustomCallBack implements Callback { @Override public void surfaceCreated(SurfaceHolder holder) {  if (!isOpenCamera)  return;  try {  initCamera();  } catch (IOException e) {  e.printStackTrace();  } } @Override public void surfaceChanged(SurfaceHolder holder, int format, int width,  int height) { } @Override public void surfaceDestroyed(SurfaceHolder holder) {  if (!isOpenCamera)  return;  freeCameraResource(); } } /** * 初始化網路攝影機 */ private void initCamera() throws IOException { if (mCamera != null) {  freeCameraResource(); } try {  mCamera = Camera.open(); } catch (Exception e) {  e.printStackTrace();  freeCameraResource(); } if (mCamera == null)  return; setCameraParams(); mCamera.setDisplayOrientation(90); mCamera.setPreviewDisplay(mSurfaceHolder); mCamera.startPreview(); mCamera.unlock(); } /** * 設定網路攝影機為豎屏 */ private void setCameraParams() { if (mCamera != null) {  Parameters params = mCamera.getParameters();  params.set("orientation", "portrait");  mCamera.setParameters(params); } } /** * 釋放網路攝影機資源 */ private void freeCameraResource() { if (mCamera != null) {  mCamera.setPreviewCallback(null);  mCamera.stopPreview();  mCamera.lock();  mCamera.release();  mCamera = null; } } private void createRecordDir() { //錄製的視頻儲存檔案夾 File sampleDir = new File(Environment.getExternalStorageDirectory()  + File.separator + "ysb/video/");//錄製視頻的儲存地址 if (!sampleDir.exists()) {  sampleDir.mkdirs(); } File vecordDir = sampleDir; // 建立檔案 try {  mVecordFile = File.createTempFile("recording", ".mp4", vecordDir);// mp4格式的錄製的視頻檔案 } catch (IOException e) {  e.printStackTrace(); } } /** * 初始化 * @throws IOException */ @SuppressLint("NewApi") private void initRecord() throws IOException { mMediaRecorder = new MediaRecorder(); mMediaRecorder.reset(); if (mCamera != null)  mMediaRecorder.setCamera(mCamera); mMediaRecorder.setOnErrorListener(this); mMediaRecorder.setPreviewDisplay(mSurfaceHolder.getSurface()); mMediaRecorder.setVideoSource(VideoSource.CAMERA);// 視頻源 mMediaRecorder.setAudioSource(AudioSource.MIC);// 音頻源 mMediaRecorder.setOutputFormat(OutputFormat.MPEG_4);// 視頻輸出格式 mMediaRecorder.setAudioEncoder(AudioEncoder.AMR_NB);// 音頻格式 mMediaRecorder.setVideoSize(mWidth, mHeight);// 設定解析度： // mMediaRecorder.setVideoFrameRate(16);// 這個我把它去掉了，感覺沒什麼用 mMediaRecorder.setVideoEncodingBitRate(1 * 1024 * 1024 * 100);// 設定幀頻率，然後就清晰了 mMediaRecorder.setOrientationHint(90);// 輸出旋轉90度，保持豎屏錄製 mMediaRecorder.setVideoEncoder(VideoEncoder.MPEG_4_SP);// 視頻錄製格式 // mediaRecorder.setMaxDuration(Constant.MAXVEDIOTIME * 1000); mMediaRecorder.setOutputFile(mVecordFile.getAbsolutePath()); mMediaRecorder.prepare(); try {  mMediaRecorder.start(); } catch (IllegalStateException e) {  e.printStackTrace(); } catch (RuntimeException e) {  e.printStackTrace(); } catch (Exception e) {  e.printStackTrace(); } } /** * 開始錄製視頻 * @param fileName *  視訊儲存位置 * @param onRecordFinishListener *  達到指定時間之後回調介面 */ public void record(final OnRecordFinishListener onRecordFinishListener) { this.mOnRecordFinishListener = onRecordFinishListener; createRecordDir(); try {  if (!isOpenCamera)// 如果未開啟網路攝影機，則開啟  initCamera();  initRecord();  mTimeCount = 0;// 時間計數器重新賦值  mTimer = new Timer();  mTimer.schedule(new TimerTask() {  @Override  public void run() {   mTimeCount++;   mProgressBar.setProgress(mTimeCount);// 設定進度條   if (mTimeCount == mRecordMaxTime) {// 達到指定時間，停止拍攝   stop();   if (mOnRecordFinishListener != null)    mOnRecordFinishListener.onRecordFinish();   }  }  }, 0, 1000); } catch (IOException e) {  e.printStackTrace(); } } /** * 停止拍攝 */ public void stop() { stopRecord(); releaseRecord(); freeCameraResource(); } /** * 停止錄製 */ public void stopRecord() { mProgressBar.setProgress(0); if (mTimer != null)  mTimer.cancel(); if (mMediaRecorder != null) {  // 設定後不會崩  mMediaRecorder.setOnErrorListener(null);  mMediaRecorder.setPreviewDisplay(null);  try {  mMediaRecorder.stop();  } catch (IllegalStateException e) {  e.printStackTrace();  } catch (RuntimeException e) {  e.printStackTrace();  } catch (Exception e) {  e.printStackTrace();  } } } /** * 釋放資源 */ private void releaseRecord() { if (mMediaRecorder != null) {  mMediaRecorder.setOnErrorListener(null);  try {  mMediaRecorder.release();  } catch (IllegalStateException e) {  e.printStackTrace();  } catch (Exception e) {  e.printStackTrace();  } } mMediaRecorder = null; } public int getTimeCount() { return mTimeCount; } //返回錄製的視頻檔案 public File getmVecordFile() { return mVecordFile; } /** * 錄製完成回調介面 */ public interface OnRecordFinishListener { public void onRecordFinish(); } @Override public void onError(MediaRecorder mr, int what, int extra) { try {  if (mr != null)  mr.reset(); } catch (IllegalStateException e) {  e.printStackTrace(); } catch (Exception e) {  e.printStackTrace(); } }}

2.視頻錄製介面檔案movie_recorder_view.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/background_dark" android:orientation="vertical"> <SurfaceView   android:id="@+id/surfaceview"   android:layout_width="fill_parent"   android:layout_height="0dp"  android:layout_weight="1"  /> <ProgressBar android:id="@+id/progressBar" style="?android:attr/progressBarStyleHorizontal" android:layout_width="match_parent" android:layout_height="2dp"  /></LinearLayout>

做好這些準備工作，下面我們就可以開始設計我們的視頻錄製功能了。PS：以上代碼取至網上，在此向大牛致敬。

3.拍攝主介面，拍攝介面有兩部分組成，上面是視頻拍攝控制項顯示，下面是使用者點擊拍攝按鈕，設定檔：activity_main.xml。

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"  android:background="@android:color/white" android:orientation="vertical"><com.example.wechatvideorecorddemo.MovieRecorderView android:id="@+id/movieRecorderView" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:layout_margin="3dp" /> <Button android:id="@+id/shoot_button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:background="@drawable/bg_movie_add_shoot" android:text="按住拍"  android:textColor="#20b6ff"/></LinearLayout>

4.有了主介面的視圖，下面我們就開始書寫我們的Activity檔案MainActivity.java：

public class MainActivity extends Activity { private MovieRecorderView mRecorderView;//視頻錄製控制項 private Button mShootBtn;//視頻開始錄製按鈕 private boolean isFinish = true; private boolean success = false;//防止錄製完成後出現多次跳轉事件 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mRecorderView = (MovieRecorderView) findViewById(R.id.movieRecorderView); mShootBtn = (Button) findViewById(R.id.shoot_button); //使用者長按事件監聽 mShootBtn.setOnTouchListener(new OnTouchListener() {  @Override  public boolean onTouch(View v, MotionEvent event) {  if (event.getAction() == MotionEvent.ACTION_DOWN) {//使用者按下拍攝按鈕   mShootBtn.setBackgroundResource(R.drawable.bg_movie_add_shoot_select);   mRecorderView.record(new OnRecordFinishListener() {   @Override   public void onRecordFinish() {    if(!success&&mRecorderView.getTimeCount()<10){//判斷使用者按下時間是否大於10秒    success = true;   handler.sendEmptyMessage(1);    }   }   });  } else if (event.getAction() == MotionEvent.ACTION_UP) {//使用者抬起拍攝按鈕   mShootBtn.setBackgroundResource(R.drawable.bg_movie_add_shoot);   if (mRecorderView.getTimeCount() > 3){//判斷使用者按下時間是否大於3秒   if(!success){    success = true;    handler.sendEmptyMessage(1);   }   } else {   success = false;   if (mRecorderView.getmVecordFile() != null) mRecorderView.getmVecordFile().delete();//刪除錄製的過短視頻   mRecorderView.stop();//停止錄製   Toast.makeText(MainActivity.this, "視頻錄製時間太短", Toast.LENGTH_SHORT).show();   }  }  return true;  } }); } @Override public void onResume() { super.onResume(); isFinish = true; if (mRecorderView.getmVecordFile() != null)  mRecorderView.getmVecordFile().delete();//視頻使用後刪除 } @Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); isFinish = false; success = false; mRecorderView.stop();//停止錄製 } @Override public void onPause() { super.onPause(); } @Override public void onDestroy() { super.onDestroy(); } private Handler handler = new Handler() { @Override public void handleMessage(Message msg) {  if(success){  finishActivity();  } } }; //視頻錄製結束後，跳轉的函數 private void finishActivity() { if (isFinish) {  mRecorderView.stop();  Intent intent = new Intent(this, SuccessActivity.class);  Bundle bundle = new Bundle();  bundle.putString("text", mRecorderView.getmVecordFile().toString());  intent.putExtras(bundle);  startActivity(intent); } success = false; } /** * 錄製完成回調 */ public interface OnShootCompletionListener {  public void OnShootSuccess(String path, int second);  public void OnShootFailure(); }}

到這裡我們仿微信的短視頻拍攝就已經大功告成，那麼下面我們檢驗一下，我們錄製的效果如何，下面我以Android提供的視頻播放控制項(VideoView)為大家介紹一下如何播放錄製的短視頻。

5.播放視頻的設定檔activity_success.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"  android:background="@android:color/white" android:orientation="vertical"> <TextView  android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="@string/app_name" /> <LinearLayout  android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <Button   android:id="@+id/button1"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_weight="1"  android:gravity="center"  android:padding="5dp"  android:text="播放"  /> <Button   android:id="@+id/button2"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_weight="1"  android:gravity="center"  android:padding="5dp"  android:text="暫停"  /> <Button   android:id="@+id/button3"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_weight="1"  android:gravity="center"  android:padding="5dp"  android:text="重播"  /> <Button   android:id="@+id/button4"  android:layout_width="match_parent"  android:layout_height="wrap_content"  android:layout_weight="1"  android:gravity="center"  android:padding="5dp"  android:text="視頻長度"  /> </LinearLayout> <VideoView android:id="@+id/videoView1" android:layout_width="wrap_content" android:layout_height="500dp" /></LinearLayout>

6.視頻播放的控制碼SuccessActivity.java:

public class SuccessActivity extends Activity implements OnClickListener{ private TextView text;//視頻儲存的路徑 private Button button1;//播放開關 private Button button2;//暫停開關 private Button button3;//重新播放開關 private Button button4;//視頻大小開關 private VideoView videoView1;//視頻播放控制項 private String file;//視頻路徑 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_success); Bundle bundle = getIntent().getExtras(); file = bundle.getString("text");//獲得拍攝的短視頻儲存地址 init(); setValue(); } //初始化 private void init() { text = (TextView) findViewById(R.id.text); button1 = (Button) findViewById(R.id.button1); button2 = (Button) findViewById(R.id.button2); button3 = (Button) findViewById(R.id.button3); button4 = (Button) findViewById(R.id.button4); videoView1 = (VideoView) findViewById(R.id.videoView1); } //設定 private void setValue() { text.setText(file); button1.setOnClickListener(this); button2.setOnClickListener(this); button3.setOnClickListener(this); button4.setOnClickListener(this); videoView1.setVideoPath(file); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.button1:  videoView1.start();  break; case R.id.button2:  videoView1.pause();   break; case R.id.button3:  videoView1.resume();  videoView1.start();  break; case R.id.button4:  Toast.makeText(this, "視頻長度："+(videoView1.getDuration()/1024)+"M", Toast.LENGTH_SHORT).show();  break; default:  break; } } }

7.添加許可權：

<!-- 視頻錄製的許可權star --><!-- 網路攝影機 --><uses-permission android:name="android.permission.CAMERA" /><!-- 音頻即聲音 --><uses-permission android:name="android.permission.RECORD_AUDIO" /><!-- sd卡寫入許可權 --><uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /><!-- 硬體支援 --><uses-feature android:name="android.hardware.camera" /><uses-feature android:name="android.hardware.camera.autofocus" /><!-- 視頻錄製的許可權end -->
