您好，我正在尝试从 android 相机中裁剪图像。I 相机已激活，并且裁剪图像的活动也已激活。
但是，我无法将裁剪后的图像传递给另一个活动。
我搜索了，我找不到解决方案。我在做什么错？也许，是因为putExtras？

我的 PhotoFragment.java
public class PhotoFragment extends Fragment{
private static final String TAG = "PhotoFragment";
//constants
private static final int PHOTO_FRAGMENT_NUM = 1;
private static final int GALLERY_FRAGMENT_NUM = 2;
private static final int CAMERA_REQUEST_CODE = 5;
@Nullable
@Override
public View onCreateView(final LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_photo, container, false);
Log.d(TAG, "onCreateView: Started.");
Button btnLaunchCamera = (Button) view.findViewById(R.id.btnLaunchCamera);
btnLaunchCamera.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "onClick: launching the camera.");
// Create intent to Open Image
Intent galleryIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(galleryIntent, CAMERA_REQUEST_CODE);
}
});
return view;
}
private boolean isRootTask(){
if(((ShareActivity)getActivity()).getTask() == 0){
return true;
}else{
return false;
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d("APP_DEBUG", String.valueOf(requestCode));
try {
// When an Image is picked
if (requestCode == CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
CropImage.activity(selectedImage)
.setGuidelines(CropImageView.Guidelines.ON)
.setMinCropResultSize(800, 800)
.setMaxCropResultSize(1000, 1000)
.start(getContext(), this);
}
// when image is cropped
else if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
CropImage.ActivityResult result = CropImage.getActivityResult(data);
Log.d("APP_DEBUG",result.toString());
if (resultCode == Activity.RESULT_OK) {
Uri resultUri = result.getUri();
Log.d("APP_DEBUG",resultUri.toString());
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), resultUri);
//pofilePic.setImageBitmap(bitmap);
Toast.makeText(getContext(), "sssss", Toast.LENGTH_SHORT).show();
if(isRootTask()) {
try {
Log.d(TAG, "onActivityResult: received new bitmap from camera" + bitmap);
Intent intent = new Intent(getContext(), NextActivity.class);
intent.putExtra(getString(R.string.selected_bitmap), bitmap);
startActivity(intent);
}catch (NullPointerException e){
Log.d(TAG, "onActivityResult: NullPointerException" + e.getMessage());
}
}else {
try {
Log.d(TAG, "onActivityResult: received new bitmap from camera" + bitmap);
Intent intent = new Intent(getContext(), AccountSettingsActivity.class);
intent.putExtra(getString(R.string.selected_bitmap), bitmap);
intent.putExtra(getString(R.string.return_to_fragment), getString(R.string.edit_profile_fragment));
startActivity(intent);
getActivity().finish();
}catch (NullPointerException e){
Log.d(TAG, "onActivityResult: NullPointerException" + e.getMessage());
}
}
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Exception error = result.getError();
}
}
else {
Toast.makeText(getActivity(), "You haven't picked Image",
Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
Toast.makeText(getActivity(), "Something went wrong"+e.getMessage(), Toast.LENGTH_LONG)
.show();
}
}
我的 NextActivity.java 是：
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_next);
mFirebaseMethods = new FirebaseMethods(NextActivity.this);
mcaption = (EditText) findViewById(R.id.caption);
setupFirebaseAuth();
ImageView backArrow = (ImageView) findViewById(R.id.ivBackArrow);
backArrow.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "onClick: closing the activity.");
finish();
}
});
TextView share = (TextView) findViewById(R.id.tvShare);
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.d(TAG, "onClick: navigating to the final share screen.");
// upload the image to firebase
Toast.makeText(NextActivity.this,"Attempting to upload a new photo", Toast.LENGTH_SHORT).show();
String caption = mcaption.getText().toString();
// check if the intent came from gallery or from the camera
if(intent.hasExtra(getString(R.string.selected_image))){
imgUrl = intent.getStringExtra(getString(R.string.selected_image));
mFirebaseMethods.uploadNewPhoto(getString(R.string.new_photo), caption, imageCount, imgUrl, null);
}
else if(intent.hasExtra(getString(R.string.selected_bitmap))){
bitmap = (Bitmap) intent.getParcelableExtra(getString(R.string.selected_bitmap));
mFirebaseMethods.uploadNewPhoto(getString(R.string.new_photo), caption, imageCount, null, bitmap);
}
}
});
setImage();
}
/**
* gets the image url from the incoming intent and displays the chosen image
*/
private void setImage(){
intent = getIntent();
ImageView image = (ImageView) findViewById(R.id.imageShare);
// check if the intent came from gallery or from the camera
if(intent.hasExtra(getString(R.string.selected_image))){
imgUrl = intent.getStringExtra(getString(R.string.selected_image));
Log.d(TAG, "setImage: got new image url: " + imgUrl);
// UniversalImageLoader handles null , oder wise we should check is image is null
UniversalImageLoader.setImage(imgUrl, image, null, mAppend);
}
else if(intent.hasExtra(getString(R.string.selected_bitmap))){
bitmap = (Bitmap) intent.getParcelableExtra(getString(R.string.selected_bitmap));
Log.d(TAG, "setImage: got new Bitmap");
image.setImageBitmap(bitmap);
}
}
我希望在 NextActivity.java 的 ImageView 图像中获得裁剪后的图像
