换种剪裁方法。
Intent intentCamera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intentCamera.putExtra(MediaStore.EXTRA_OUTPUT, imagePhotoUri); startActivityForResult(intentCamera, PHOTO_REQUEST_CAREMA);
public static void cropImageUri(Activity activity, Uri orgUri, Uri desUri, int width, int height, int requestCode) { Intent intent = new Intent("com.android.camera.action.CROP"); intent.setDataAndType(orgUri, "image/*"); intent.putExtra("crop", "true"); intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); intent.putExtra("outputX", width); intent.putExtra("outputY", height); intent.putExtra("scale", true); //将剪切的图片保存到目标Uri中 intent.putExtra(MediaStore.EXTRA_OUTPUT, desUri); intent.putExtra("return-data", false); intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString()); intent.putExtra("noFaceDetection", true); activity.startActivityForResult(intent, requestCode); }
private static Bitmap decodeUriAsBitmap(Context context, Uri uri) { Bitmap bitmap; try { bitmap = BitmapFactory.decodeStream(context.getContentResolver().openInputStream(uri)); } catch (FileNotFoundException e) { e.printStackTrace(); return null; } return bitmap; }
