Android图像捕获返回结果\u取消
我正在尝试使用MediaStore.ACTION\u IMAGE\u CAPTURE拍摄个人资料照片 启动意图的代码:Android图像捕获返回结果\u取消,android,android-intent,android-camera,mediastore,Android,Android Intent,Android Camera,Mediastore,我正在尝试使用MediaStore.ACTION\u IMAGE\u CAPTURE拍摄个人资料照片 启动意图的代码: Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); File myPicture = new File(OfflineApp.getAppContext().getFilesDir() + "/" + getResources().getString(R.string.contact_photos
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File myPicture = new File(OfflineApp.getAppContext().getFilesDir() + "/" + getResources().getString(R.string.contact_photos_dir), getResources().getString(R.string.my_photo_file_name));
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(myPicture));
startActivityForResult(cameraIntent, REQUEST_CODE_TAKE_PHOTO);
以及onActivityResult部分:
case REQUEST_CODE_TAKE_PHOTO:
if (resultCode == RESULT_OK) {
String path = new File(OfflineApp.getAppContext().getFilesDir() + "/" + getResources().getString(R.string.contact_photos_dir), getResources().getString(R.string.my_photo_file_name)).getAbsolutePath();
ContactManager.getInstance().updateMyImage(path);
}
break;
但是,结果代码总是
result\u cancelled
,仅当我提供了MediaStore.EXTRA\u输出时,即使文件不存在。好的。发现了问题
由于Camera Intent正在启动Camera应用程序,因此它无法访问“我的应用程序”文件夹。通过传递外部文件夹文件并将其复制到我的本地文件夹,修复了此问题
干杯。您可以让相机应用程序将图像保存在这样的外部文件中,然后稍后再使用该文件中的图像
private void captureImage() {
// You can pass an external file Uri to the intent to which the camera app can write
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// File file = new File(getCacheDir(), IMAGE_FILENAME); // this doesn't work as the camera app doesn't have permission to this apps cache dir
// File file = new File("/sdcard/image.jpg"); // avoid hardcoding file names
File file = new File(Environment.getExternalStorageDirectory(), IMAGE_FILENAME);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
// intent.setData(Uri.fromFile(file));
// intent.putExtra(MediaStore.EXTRA_OUTPUT, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, REQUEST_CODE_CAPTURE_IMAGE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK){
if(requestCode == REQUEST_CODE_CAPTURE_IMAGE){
File file = new File(Environment.getExternalStorageDirectory(), IMAGE_FILENAME);
Uri uri = Uri.fromFile(file);
mImagePath = uri.getPath();
String extension = MimeTypeMap.getFileExtensionFromUrl(mImagePath);
if(extension != null){
mImageMIMEType = MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
} else {
mImageMIMEType = "image/jpg"; // fallback, also a best guess
}
// use image here
}
}
}
请改用此文件:
File storageDir = context.getExternalFilesDir(Environment.DIRECTORY_PICTURES);
try {
File myPicture = File.createTempFile(String.valueOf(DateUtils.nowInMillis()), you_extension, storageDir);
} catch (Exception e) {
e.printStackTrace();
}
你能和我们分享你的代码解决方案吗?是否只是更改了这一位:File myPicture=new File(OfflineApp.getAppContext().getFilesDir()+“/”+getResources().getString(R.string.contact_photos_dir),getResources().getString(R.string.my_photo_File_name));谢谢
