干货

相机拍照的回调

/** * Equivalent to takePicture(shutter, raw, null, jpeg). * * @see #takePicture(ShutterCallback, PictureCallback, PictureCallback, PictureCallback) */ public final void takePicture(ShutterCallback shutter, PictureCallback raw, PictureCallback jpeg) { takePicture(shutter, raw, null, jpeg); }

那么，让拍照的时候有“咔嚓”的声音，就需要去处理这个ShutterCallback

Camera.ShutterCallback shutterCallback = new Camera.ShutterCallback() { @Override public void onShutter() { try { AudioManager meng = (AudioManager) TakePhotoActivity.this.getSystemService(Context.AUDIO_SERVICE); int volume = meng.getStreamVolume(AudioManager.STREAM_NOTIFICATION); if (volume != 0) { if (mShootSound == null) { mShootSound = MediaPlayer.create(TakePhotoActivity.this, Uri.parse("file:///system/media/audio/ui/camera_click.ogg")); } if (mShootSound != null) { mShootSound.start(); } } } catch (Exception e) { e.getStackTrace(); } } };
