Firebase Android：数据库增长时出现问题

在测试期间，我的数据库中有大约30个引号，大约有6个用户

我现在添加了我的报价的其余部分

总数约为2000：

问题： 加载应用程序需要很长时间，它会崩溃并转到页面等待应用程序或退出。然后我减少到200个报价，但仍有问题（崩溃前可能会显示一个报价）

我在做什么？ 我在数据库中引用我的报价，每次有人打开主页时，我都会得到一个随机报价（不知道如何每天得到一个报价）

引用的JSON片段：

    {
   "Quotes": {
       "1": {
          "Name": "Abbey, Edward",
          "Quote": "In social institutions, the whole is always less than the sum of its parts. There will never be a state as good as its people, or a church worthy of its congregation, or a university equal to its faculty and students."
       },
       "2": {
          "Name": "Adams, George Matthew",
          "Quote": "There is no such thing as a self-made man. We are made up of thousands of others. Everyone who has ever done a kind deed for us, or spoken one word of encouragement to us, has entered into the makeup of our character and our thoughts, as well as our success."
       },
       "3": {
          "Name": "Albani, Emma",
          "Quote": "I had always loved beautiful and artistic things, though before leav"
       },
       "4": {
          "Name": "Borman, Frank",
          "Quote": "Exploration is really the essence of the human spirit."
       },

private void showQuote(){

    databaseReference = FirebaseDatabase.getInstance().getReference("Quotes");
    databaseReference.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            int count = (int) dataSnapshot.getChildrenCount();
            for(DataSnapshot data: dataSnapshot.getChildren()){
                int rand = new Random().nextInt(count);
                for (int i = 0; i < rand; i++) {
                    String authorName = data.child("Name").getValue().toString();
                    String quoteGiven = data.child("Quote").getValue().toString();
                    name.setText("- " + authorName);
                    quote.setText(quoteGiven);
                }
            }
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {
            Toast.makeText(MainActivity.this, "Loading Quote failed", Toast.LENGTH_SHORT).show();
        }
    });

}

 {
  "rules": {
    "users": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
       }
      },
      "Quotes": {
       ".read": true,
        ".write": false
    }
  }
}

。。。。。。。。等

我的代码：

    {
   "Quotes": {
       "1": {
          "Name": "Abbey, Edward",
          "Quote": "In social institutions, the whole is always less than the sum of its parts. There will never be a state as good as its people, or a church worthy of its congregation, or a university equal to its faculty and students."
       },
       "2": {
          "Name": "Adams, George Matthew",
          "Quote": "There is no such thing as a self-made man. We are made up of thousands of others. Everyone who has ever done a kind deed for us, or spoken one word of encouragement to us, has entered into the makeup of our character and our thoughts, as well as our success."
       },
       "3": {
          "Name": "Albani, Emma",
          "Quote": "I had always loved beautiful and artistic things, though before leav"
       },
       "4": {
          "Name": "Borman, Frank",
          "Quote": "Exploration is really the essence of the human spirit."
       },

private void showQuote(){

    databaseReference = FirebaseDatabase.getInstance().getReference("Quotes");
    databaseReference.addListenerForSingleValueEvent(new ValueEventListener() {
        @Override
        public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
            int count = (int) dataSnapshot.getChildrenCount();
            for(DataSnapshot data: dataSnapshot.getChildren()){
                int rand = new Random().nextInt(count);
                for (int i = 0; i < rand; i++) {
                    String authorName = data.child("Name").getValue().toString();
                    String quoteGiven = data.child("Quote").getValue().toString();
                    name.setText("- " + authorName);
                    quote.setText(quoteGiven);
                }
            }
        }

        @Override
        public void onCancelled(@NonNull DatabaseError databaseError) {
            Toast.makeText(MainActivity.this, "Loading Quote failed", Toast.LENGTH_SHORT).show();
        }
    });

}

 {
  "rules": {
    "users": {
      "$uid": {
        ".read": "auth != null && auth.uid == $uid",
        ".write": "auth != null && auth.uid == $uid"
       }
      },
      "Quotes": {
       ".read": true,
        ".write": false
    }
  }
}

我的要求是什么？

我想能够显示一个报价每天，如果这是不可能的随机显示一个报价。如果我继续做随机报价，我可以做些什么来确保它不会超载应用程序和崩溃。我希望有很多引用，而不是删除和添加新的不时

1.“应用程序加载时间太长”

是否有

databaseRef.keepSynced（true）

这将加载所有数据库，因此需要很长时间

你应该只读你想要的

或者您可以
FirebaseDatabase.getInstance（）.setPersistenceEnabled（Base.dataPersistence）

它将保留数据而不会长时间重复读取

2.你应该检查你的数据库，如果格式错误，它就会死掉

3.我有一个最简单的方法，你只需在firebase数据库根目录中记录大小

您只需读取大小，并生成随机整数以获得报价，或先生成随机数公式，即可轻松指定报价，无需下载所有内容。
这是否回答了您的问题？
