我正在尝试根据他的UID将用户的电话号码插入firebase数据库,我正在关注本教程this这里是我的代码,
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_settings_update);
mAuth = FirebaseAuth.getInstance();
UserName = (EditText) findViewById(R.id.username);
phoneNumber = (EditText) findViewById(R.id.phonenumber);
submit = (Button) findViewById(R.id.update);
dbr = FirebaseDatabase.getInstance().getReference();
progressDialoge = new ProgressDialog(UserSettingsUpdate.this);
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//updating the data in the user feild
String username = UserName.getText().toString().trim().toLowerCase();
String phonenumber = phoneNumber.getText().toString().trim();
UserInformation userInformation = new UserInformation(username,phonenumber);
//getting the current user and updating the details to his/her UID
progressDialoge.setMessage("Updating settings");
progressDialoge.show();
FirebaseUser currentUser = mAuth.getCurrentUser();
dbr.child(currentUser.getUid()).setValue(userInformation);
progressDialoge.dismiss();
Toast.makeText(UserSettingsUpdate.this, "its being updated", Toast.LENGTH_LONG).show();
startActivity(new Intent(UserSettingsUpdate.this, MainActivity.class));
}
});
}
}
所有库都是有序的,在本教程中,使用数据库所需的变量创建一个新的java类,这里是java类,
public class UserInformation {
public String username;
public String PhoneNumber;
public void UserInformation(){
}
public UserInformation(String username, String phoneNumber) {
this.username = username;
PhoneNumber = phoneNumber;
}
}
这是XML代码,
<EditText
android:id="@+id/phonenumber"
android:layout_width="368dp"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="8dp"
android:hint="Phone Number"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@+id/username"
app:layout_constraintVertical_bias="0.123" />
<EditText
android:id="@+id/username"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="133dp"
android:layout_weight="1"
android:hint="Username"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/update"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginTop="7dp"
android:text="Submit"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toBottomOf="@+id/phonenumber"
app:layout_constraintVertical_bias="0.152" />
在MainActivity上有一个启动UpdateUserSettings Activity的按钮,按钮设置为正确重定向我的UserSettingsUpdate的Java文件有问题,因为我尝试在登录后将用户重定向到此活动该应用程序每次都崩溃。

我看了你正在关注的教程,使用firebase-database的人是9,Firebase数据库的当前版本是10.0.1,我建议你更新你的年级,这应该做。
