我正在尝试拍摄照片并将其保存在SD卡中。生成了图像uri,当我调用startActivityForResult时,它返回而不调用onActivityResult。
private Uri dispatchTakePictureIntent() {
Uri uri = null;
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
Log.d("dispatchTakePictureIntent", "inside try");
} catch (IOException ex) {
// Error occurred while creating the File
Log.d("dispatchTakePictureIntent", "inside catch");
}
// Continue only if the File was successfully created
if (photoFile != null) {
Log.d("dispatchTakePictureIntent", "inside secondif");
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
Log.d("dispatchTakePictureIntent","after putExtra");
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
uri = Uri.fromFile(photoFile);
Log.d("dispatchTakePictureIntent", uri.toString());
return uri;
}
}
return uri;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d("onActivityResult", "outside if");
ImageView recipeImageView = (ImageView)this.findViewById(R.id.dishImage);
Log.d("onActivityResult", "outside if");
Log.d("requestcode", requestCode+"");
Log.d("REQUEST_IMAGE_CAPTURE", REQUEST_IMAGE_CAPTURE+"");
Log.d("resultcode", resultCode+"");
Log.d("REESULT_OK", RESULT_OK+"");
Log.d("onActivityResult", "inside if");
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Log.d("onActivityResult", "inside if");
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
recipeImageView.setImageBitmap(imageBitmap);
}
Log.d("onActivityResult", "completed if");
}
String mCurrentPhotoPath;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
Log.d("createImageFile", Environment.DIRECTORY_PICTURES);
Log.d("createImageFile", storageDir.toString());
Log.d("createImageFile", imageFileName);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
this.getCacheDir() /* directory */
//storageDir
);
Log.d("createImageFile", image.toString());
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
Log.d("createImageFile", mCurrentPhotoPath);
return image;
}
然而,当我只是调用缩略图而不将其保存在SD卡中时,会调用onActivityResult并显示缩略图
private void dispatchTakePictureIntentThumb() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
当我查看日志消息时。

通过其他帖子,我确保一切顺利。

在功能方面,能够打开相机并拍照,但是当我们尝试保存时,它仍处于相同的状态。

我遇到过这个问题。 你在活动的属性中使用android:launchMode =“singleInstance”吗?

以下是将图像保存在外部目录中的功能
public static String saveImageInExternalCacheDir(Context context, Bitmap bitmap, String myfileName) {
String fileName = myfileName.replace(' ', '_') + getCurrentDate().toString().replace(' ', '_').replace(":", "_");
String filePath = (context.getExternalCacheDir()).toString() + "/" + fileName + ".jpg";
try {
FileOutputStream fos = new FileOutputStream(new File(filePath));
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fos);
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
return filePath;
}
