在我使用过的SettingsActivity下：
public class SettingsActivity extends AppCompatActivity
{
private Button UpdateAccountSettings;
private EditText userName, userStatus;
private CircleImageView userProfileImage;
private String currentUserID;
private FirebaseAuth mAuth;
private DatabaseReference RootRef;
private static final int GalleryPick = 1;
private StorageReference UserProfileImagesRef;
private ProgressDialog loadingBar;
private Toolbar SettingsToolBar;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
mAuth = FirebaseAuth.getInstance();
currentUserID = mAuth.getCurrentUser().getUid();
RootRef = FirebaseDatabase.getInstance().getReference();
UserProfileImagesRef = FirebaseStorage.getInstance().getReference().child("Profile Images");
InitializeFields();
userName.setVisibility(View.VISIBLE);
UpdateAccountSettings.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view)
{
UpdateSettings();
}
});
RetrieveUserInfo();
userProfileImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view)
{
Intent galleryIntent = new Intent();
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, GalleryPick);

您可以将其添加到build.gradle并标记依赖项
mongodump --db mydb --out /var/www/html/'date +"%m-%d-%y"'
用于创建Circle ImageView
尝试
implementation 'de.hdodenhof:circleimageview:3.0.0'
为加载图像添加了毕加索库
