android 调用camera有关操作

android 调用camera相关操作
1，通过intent调用camera

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");		File photo = new File(Environment.getExternalStorageDirectory(),				getPhotoFileName());		Log.i(TAG,"getPhotoFileName():" +getPhotoFileName());		intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));		imageUri = Uri.fromFile(photo);		startActivityForResult(intent, GET_PHOTO_WITH_CAMERA);private String getPhotoFileName() {		Date date = new Date(System.currentTimeMillis());		SimpleDateFormat dateFormat = new SimpleDateFormat(				"'IMG'_yyyy-MM-dd_HH-mm-ss");		return dateFormat.format(date) + ".jpg";	}

然后onActivityResult()中

if (requestCode == GET_PHOTO_WITH_CAMERA) {				// doCropPhoto(mCurrentPhotoFile);				Uri selectedImage = imageUri;				Log.i(TAG, "uri:" + imageUri.toString());				getContentResolver().notifyChange(selectedImage, null);				ContentResolver cr = getContentResolver();				Bitmap bitmap;				try {					bitmap = android.provider.MediaStore.Images.Media							.getBitmap(cr, selectedImage);					BitmapDrawable bd = new BitmapDrawable(bitmap);					headerImage.setBackgroundDrawable(bd);				} catch (Exception e) {					Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)							.show();				}			}

2，如果要调用gallery去剪辑的话
doCropPhoto（photo）

	protected void doCropPhoto(File f) {		try {			// 启动gallery去剪辑这个照片			final Intent intent = getCropImageIntent(Uri.fromFile(f));			startActivityForResult(intent, GET_PHOTO_WITH_GALLARY);		} catch (Exception e) {		}	}	public static Intent getCropImageIntent(Uri photoUri) {		Intent intent = new Intent("com.android.camera.action.CROP");		intent.setDataAndType(photoUri, "image/*");		intent.putExtra("crop", "true");		intent.putExtra("aspectX", 1);		intent.putExtra("aspectY", 1);		intent.putExtra("outputX", 80);		intent.putExtra("outputY", 80);		intent.putExtra("return-data", true);		return intent;	}
