问题描述
的完整code我的片段
:
public class ProfileEditPictureFragment extends BaseFragment implements OnClickListener {
private ImageView imageView = null;
private Button buttonPick = null;
private Button buttonSave = null;
private Button buttonCancel = null;
private File tempFile = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setRetainInstance(true);
this.sessionProfilePreferences = new SessionProfilePreferences(this.getActivity());
this.sessionLoginPreferences = new SessionLoginPreferences(this.getActivity());
this.sessionLoginSingleton = SessionLoginSingleton.getInstance(this.getActivity());
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_MOUNTED.equals(state)) {
this.tempFile = new File(Environment.getExternalStorageDirectory(), "temp_photo.jpg");
}
else {
this.tempFile = new File(this.getActivity().getFilesDir(), "temp_photo.jpg");
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_profile_picture_edit, container, false);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
this.imageView = (ImageView) view.findViewById(R.id.profile_picture_edit_imageview_photo);
this.buttonPick = (Button) view.findViewById(R.id.profile_picture_edit_button_pick);
this.buttonPick.setOnClickListener(this);
this.buttonSave = (Button) view.findViewById(R.id.profile_picture_edit_button_save);
this.buttonSave.setOnClickListener(this);
this.buttonCancel = (Button) view.findViewById(R.id.profile_picture_edit_button_cancel);
this.buttonCancel.setOnClickListener(this);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.v("ProfileEditPicture", "requestCode: " + requestCode);
Log.v("ProfileEditPicture", "resultCode: " + resultCode);
Log.v("ProfileEditPicture", "data: " + data);
Bitmap bitmap = null;
if(resultCode == Activity.RESULT_OK) {
if (requestCode == Globals.REQUEST_PICK_PHOTO) {
try {
InputStream inputStream = this.getActivity().getContentResolver().openInputStream(data.getData());
FileOutputStream fileOutputStream = new FileOutputStream(this.tempFile);
Helper.copyStream(inputStream, fileOutputStream);
fileOutputStream.close();
inputStream.close();
this.startCropImage();
} catch (Exception e) {}
} else if (requestCode == Globals.REQUEST_CROP_PHOTO) {
String path = data.getStringExtra(CropActivity.IMAGE_PATH);
if (path == null) {
return;
}
bitmap = BitmapFactory.decodeFile(this.tempFile.getPath());
this.imageView.setImageBitmap(bitmap);
}
}
}
@Override
public void onClick(View view) {
switch(view.getId()) {
case R.id.profile_picture_edit_button_pick : {
this.pickPicture();
} break;
case R.id.profile_picture_edit_button_save : {
} break;
case R.id.profile_picture_edit_button_cancel : {
this.getActivity().finish();
}
}
}
private void pickPicture() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
this.startActivityForResult(Intent.createChooser(intent, "Select Picture"), Globals.REQUEST_PICK_PHOTO);
}
private void startCropImage() {
Intent intent = new Intent(this.getActivity(), CropActivity.class);
intent.putExtra(CropActivity.IMAGE_PATH, this.tempFile.getPath());
intent.putExtra(CropActivity.SCALE, true);
intent.putExtra(CropActivity.ASPECT_X, 3);
intent.putExtra(CropActivity.ASPECT_Y, 2);
this.startActivityForResult(intent, Globals.REQUEST_CROP_PHOTO);
}
}
但结果code
总是 0
,数据总是空
。权限设置ofcourse。
But the resultCode
is always 0
and the data is always null
. Permissions are set ofcourse.
那么,怎样才能挑我图片来自画廊?

推荐答案
尝试ACTION_PICK这样
Try ACTION_PICK like this
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
和对活动结果
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
try {
if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgDecodableString = cursor.getString(columnIndex);
cursor.close();
ImageView imgView = (ImageView) findViewById(R.id.imgView);
imgView.setImageBitmap(BitmapFactory
.decodeFile(imgDecodableString));
} else {
Toast.makeText(this, "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
.show();
}
}
