问题交换图像

Question

我有一个 ProfileActivity：

public class ProfileActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_profile);

    final ImageView exampleImage = (ImageView) this.findViewById(R.id.exampleImageView);
    exampleImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // [TODO] Implement application behavior when the user clicks the profile picture
            //Toast.makeText(ProfileActivity.this, "Button Clicked", Toast.LENGTH_SHORT).show();
            startActivity(new Intent(ProfileActivity.this, GalleryActivity.class));
        }
    });
}

我还有一个名为“GalleryActivity”的活动。这个概念是让用户从图库中选择一张图片，然后用它来替换原始的个人资料图片。

public class GalleryActivity extends AppCompatActivity {
    ImageView imageView;
    private static final int PICK_IMAGE = 100;
    Uri imageUri;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
            startActivityForResult(gallery, PICK_IMAGE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode == RESULT_OK && requestCode == PICK_IMAGE) {
                    imageUri = data.getData();
                    imageView.setImageURI(imageUri);
            }
    }

}

但是，当我单击图库的图像时，它并没有将其作为新的个人资料图像，而是将我带回原始图像。 发生了什么，我该如何解决？

你可以使用 Github 库，它会对你有所帮助。

这里是Link。

ImagePicker.Companion.with(this)
                .crop()                    //Crop image(Optional), Check Customization for more option
                .compress(1024)            //Final image size will be less than 1 MB(Optional)
                .maxResultSize(1080, 1080)
                .start();//Final image resolution will be less than 1080 x 1080(Optional)

关于活动结果。

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {

            if (data != null) {
                selectedFileURI = data.getData();

                if (selectedFileURI != null && !Objects.requireNonNull(selectedFileURI.getPath()).isEmpty()) {

                    btnUpdate.setVisibility(View.GONE);
                    civUser.setImageURI(selectedFileURI);
                    Glide.with(context).load(selectedFileURI).into(civUser);
                    btnUploadDp.setVisibility(View.VISIBLE);

                } else {

                    Functions.showSnackBar(context, "Cannot Get this Image");

                }
            }

        }
    }
