我试图将压缩的图像上传到我的Firebase数据库中以将其显示为缩略图，然后再插入图像压缩代码，我的个人资料图片会正确显示，但在插入之后，我的代码只能在个人资料所在的部分使用图像已上传，但涉及到拇指部分时，仅显示进度条，不显示成功吐司或失败吐司。下面是代码。
mImageStorage = FirebaseStorage.getInstance().getReference();
mCurrentUser = FirebaseAuth.getInstance().getCurrentUser();
String uuid = mCurrentUser.getUid();
mUserRef = FirebaseDatabase.getInstance().getReference().child("Users").child(uuid);
以上部分是针对Firebase初始化的。
mImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(galleryIntent, "SELECT IMAGE"), GALLERY_PICK);
// start picker to get image for cropping and then use the image in cropping activity
/* CropImage.activity()
.setGuidelines(CropImageView.Guidelines.ON)
.start(SettingActivity.this);*/
}
});
按钮相机侦听器。
@Override

super.onActivityResult(requestCode, resultCode, data);

此位用于图像上传，谢谢！
