我正在使用下面的代码来激发意图并打开android Gallery,以便用户选择图片。
userProfileImage.setOnClickListener(v ->
{
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, GalleryPick);
});
图库可以很好地打开,但是当用户单击图像时,应用程序显示“选择源”,所有可以打开图像的应用程序。如果用户单击其中之一,则他们必须再次选择图像,然后图像才能继续。得到结果后,下面的代码显示了我的代码:
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == GalleryPick && resultCode == RESULT_OK && data != null)
{
Uri ImageUri = data.getData();
CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.setAspectRatio(1,1)
.start(this);
}
if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE)
{
CropImage.ActivityResult result = CropImage.getActivityResult(data);
if (resultCode == RESULT_OK)
{
loadingBar.setTitle("Set Profile Image");
loadingBar.setMessage("Please Wait...");
loadingBar.setCanceledOnTouchOutside(false);
loadingBar.show();
assert result != null;
final Uri resultUri = result.getUri();
final StorageReference filePath = userProfileImagesRef.child(currentUserID + ".jpg");
filePath.putFile(resultUri).addOnSuccessListener(taskSnapshot -> filePath.getDownloadUrl().addOnSuccessListener(uri -> {
final String downloadUrl = uri.toString();
rootRef.child("Users").child(currentUserID).child("image").setValue(downloadUrl)
.addOnCompleteListener(task ->
{
if (task.isSuccessful())
{
Toast.makeText(SettingsActivity.this, "Profile image stored to firebase database successfully.", Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}
else
{
String message = Objects.requireNonNull(task.getException()).getMessage();
Toast.makeText(SettingsActivity.this, "Error Occurred..." + message, Toast.LENGTH_SHORT).show();
loadingBar.dismiss();
}
});
}));
}
else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE)
{
assert result != null;
Exception error = result.getError();
}
}
}
有人可以告诉我我在做什么错以及如何解决此问题吗?我希望让用户选择他们要用来打开图片的应用。
