带有Cloud Firestore的Android Studio：不写入数据库

标签： android firebase google-cloud-firestore cloud

我目前正在为我的高级项目从事Android Studio项目。简而言之，该项目是事件创建者。我将Cloud firestore用作数据库，但是出现问题。我提供了以下代码；当我按下提交按钮时，日志将打印该按钮被按下，功能已启动以及即将开始将代码提交到Firebase的代码的日志，但无论成功与否，都不会打印出来。任何帮助将不胜感激！谢谢！

以下是活动的Java代码： 

import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.EditText;

import com.google.android.gms.tasks.OnFailureListener;
import com.google.android.gms.tasks.OnSuccessListener;
import com.google.firebase.firestore.DocumentReference;
import com.google.firebase.firestore.FirebaseFirestore;

import java.util.HashMap;
import java.util.Map;

public class EventActivity extends AppCompatActivity implements 
View.OnClickListener {
    private static final String TAG = "EventSaved";
    FirebaseFirestore db = FirebaseFirestore.getInstance();

    //texts
    private EditText eventTitle;
    private EditText eventAddress;
    private EditText eventState;
    private EditText eventCity;
    private EditText eventZip;
    private EditText eventDate;
    private EditText eventTime;
    private EditText eventRules;

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

        //views
        eventTitle = findViewById(R.id.eventTitle);
        eventAddress = findViewById(R.id.eventAddress);
        eventState = findViewById(R.id.eventState);
        eventCity = findViewById(R.id.eventCity);
        eventZip = findViewById(R.id.eventZipCode);

        //buttons
        findViewById(R.id.submitButton).setOnClickListener(this);
        findViewById(R.id.clearButton).setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        int i = v.getId();
        if (i == R.id.submitButton){
            Log.d(TAG, "Submit Button was Pushed!");
            saveEvent();
        } else if (i == R.id.clearButton){
            //reset the form
        }
    }//end onClick

    private void saveEvent(){
        Log.d(TAG,"Save Event function started");
        String title = eventTitle.getText().toString();
        String address = eventAddress.getText().toString();
        String city = eventCity.getText().toString();
        String state = eventState.getText().toString();

        Map<String, Object> event = new HashMap<>();
        event.put("title", title);
        event.put("address", address);
        event.put("city", city);
        event.put("state", state);

        Log.d(TAG,"Begin Write to Database!");
    // Add a new document with a generated ID
    db.collection("events")
            .add(event)
            .addOnSuccessListener(new OnSuccessListener<DocumentReference(){
                    @Override
                     public void onSuccess(DocumentReference 
                     documentReference){
                        Log.d(TAG, "Success!");
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                        Log.w(TAG, "Error adding document", e);
                    }
                });
    }
}

供参考；这也是我的应用程序build.gradle：

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.google.firebase:firebase-auth:16.1.0'
    implementation 'com.google.firebase:firebase-core:16.0.7'
    implementation 'com.google.firebase:firebase-firestore:18.0.1'
    implementation 'com.android.support:multidex:1.0.3'
    implementation 'com.google.android.gms:play-services-maps:16.1.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-

这是当我按下“提交”按钮时发生的情况的日志：
