问题:在三星S3的onActivityResult(int requestCode, int resultCode, Intent data)中获取相机意图的数据为空。但在其他设备上工作得很好。我定制了获取数据的代码,并在网上搜索了这个问题,但没有发现任何有用的东西。
代码:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_CAMERA && data != null && data.getData() != null)
else if (requestCode == TAKE_CAMERA) {
if (resultCode != RESULT_OK) return;
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setDataAndType(tempFileUri, "image/*");
intent.putExtra("outputX", 90);
intent.putExtra("outputY", 90);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
startActivityForResult(intent, CROP_CAMERA);
} else if (requestCode == CROP_CAMERA && data != null) {
Bitmap photo = data.getExtras().getParcelable("data");
try {
FileOutputStream out = new FileOutputStream(tempFileUri.getPath());
photo.compress(Bitmap.CompressFormat.JPEG, 90, out);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
if (photo != null) {
imagePhoto.setImageBitmap(photo);
<my code>
}

我也面临过同样的问题,我的工作如下,它肯定会帮助你解决一次:

三星Galaxy S3相机解决方案
在调用捕获的图像时编写以下代码:
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, PICK_FROM_CAMERA);并通过以下方式在OnActivityResult()方法中获取URI:
if (resultCode != RESULT_OK)
return;
switch (requestCode) {
case PICK_FROM_CAMERA:
Log.i("TAG", "Inside PICK_FROM_CAMERA");
// Describe the columns you'd like to have returned. Selecting from
// the Thumbnails location gives you both the Thumbnail Image ID, as
// well as the original image ID
try {
Log.i("TAG", "inside Samsung Phones");
String[] projection = {
MediaStore.Images.Thumbnails._ID, // The columns we want
MediaStore.Images.Thumbnails.IMAGE_ID,
MediaStore.Images.Thumbnails.KIND,
MediaStore.Images.Thumbnails.DATA };
String selection = MediaStore.Images.Thumbnails.KIND + "=" + // Select
// only
// mini's
MediaStore.Images.Thumbnails.MINI_KIND;
String sort = MediaStore.Images.Thumbnails._ID + " DESC";
// At the moment, this is a bit of a hack, as I'm returning ALL
// images, and just taking the latest one. There is a better way
// to
// narrow this down I think with a WHERE clause which is
// currently
// the selection variable
Cursor myCursor = this.managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection, selection, null, sort);
long imageId = 0l;
long thumbnailImageId = 0l;
String thumbnailPath = "";
try {
myCursor.moveToFirst();
imageId = myCursor
.getLong(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.IMAGE_ID));
thumbnailImageId = myCursor
.getLong(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID));
thumbnailPath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails.DATA));
} finally {
// myCursor.close();
}
// Create new Cursor to obtain the file Path for the large image
String[] largeFileProjection = {
MediaStore.Images.ImageColumns._ID,
MediaStore.Images.ImageColumns.DATA };
String largeFileSort = MediaStore.Images.ImageColumns._ID
+ " DESC";
myCursor = this.managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
largeFileProjection, null, null, largeFileSort);
String largeImagePath = "";
try {
myCursor.moveToFirst();
// This will actually give yo uthe file path location of the
// image.
largeImagePath = myCursor
.getString(myCursor
.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.DATA));
mImageCaptureUri = Uri.fromFile(new File(
largeImagePath));
} finally {
// myCursor.close();
}
// These are the two URI's you'll be interested in. They give
// you a
// handle to the actual images
Uri uriLargeImage = Uri.withAppendedPath(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
String.valueOf(imageId));
Uri uriThumbnailImage = Uri.withAppendedPath(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
String.valueOf(thumbnailImageId));
// I've left out the remaining code, as all I do is assign the
// URI's
// to my own objects anyways...
} catch (Exception e) {
Log.i("TAG",
"inside catch Samsung Phones exception " + e.toString());
}
try {
Log.i("TAG", "URI Normal:" + mImageCaptureUri.getPath());
} catch (Exception e) {
Log.i("TAG", "Excfeption inside Normal URI :" + e.toString());
}
//doCrop();

如果您提供的是MediaStore.EXTRA_OUTPUT,那么意图是空的,但是您将在您提供的文件中获得照片(Uri.fromFile(f))。

我通过告诉相机活动将图像保存在SD卡上解决了这个问题:
tempImageNameUri = "some temporary name";
i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT,tempImageNameUri);
i.putExtra("return-data", true);
startActivityForResult(i,SOME_CONSTANT);当被调用的活动完成后,在onActivityResult中从临时路径中从SD卡中获取项并使用它。
