Question

我尝试用户填写表单，一旦用户点击“提交”＃39;按钮，数据将存储在Firebase中的新密钥中。新密钥只有在“提交”后才会存在。单击按钮将数据传递到Firebase。

这是我目前的代码：

CustomersDetail.java

public class CustomersDetail extends AppCompatActivity {

    FirebaseDatabase database;
    DatabaseReference customerDetails;

    TextView editPhone, editName, editDOB, editEmail;

    Button btnSubmit;

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

        //Firebase
        database = FirebaseDatabase.getInstance();
        customerDetails = database.getReference("Customer Details");

        btnSubmit = (Button)findViewById(R.id.btnSubmit);


        btnSubmit.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
                //Click 'Submit'
                //Submit to Firebase
                //Create new Request
                CustomerDetail custDetail = new CustomerDetail(
                        editPhone.getText().toString(),
                        editName.getText().toString(),
                        editDOB.getText().toString(),
                        editEmail.getText().toString()
                );

                //Submit to Firebase
                customerDetails.child(String.valueOf(System.currentTimeMillis()))
                        .setValue(custDetail);
            }
        });

    }
}

我有点困惑，好像你在使用TextView或EdiTtext一样？
无论您使用什么，都需要将其与xml文件中的内容相关联。

将此代码放在onClick（）方法中，或者创建一个额外的方法，在按钮的onClick（）中调用该方法，然后可以在外面编写方法的定义。

向Firebase提交数据的代码可以通过以下方式完成：

customerDetails.child(String.valueOf(System.currentTimeMillis()))
                    .setValue(custDetail);

//TO READ DATA

customerDetails.child(String.valueOf(System.currentTimeMillis())).addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {

            CustomerDetail cd = dataSnapshot.getValue(CustomerDetail.class);
}
 @Override
        public void onCancelled(DatabaseError databaseError) {

            Log.d(TAG, "Failed To Read data", databaseError.toException());

        }
    });

如何将用户提交的数据转换为新的Firebase密钥，仅在单击“提交”按钮以传递数据时创建密钥
