Android studio firebase查询。我只希望显示具有相同uid的学生和孩子

implementation 'com.google.firebase:firebase-database:20.0.0'

{
  "users" : {
    "student1" : {
      "uid" : "uid1",
      "name" : "学生1"
    },
    "student2" : {
      "uid" : "uid2",
      "name" : "学生2"
    },
    "child1" : {
      "uid" : "uid1",
      "name" : "孩子1"
    },
    "child2" : {
      "uid" : "uid2",
      "name" : "孩子2"
    }
  }
}

DatabaseReference databaseRef = FirebaseDatabase.getInstance().getReference("users");
Query query = databaseRef.orderByChild("uid").equalTo("uid1");

query.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
        for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
            // 获取具有相同uid的学生和孩子数据
            String name = snapshot.child("name").getValue(String.class);
            Log.d("TAG", "姓名：" + name);
        }
    }

    @Override
    public void onCancelled(@NonNull DatabaseError databaseError) {
        Log.d("TAG", "查询取消：" + databaseError.getMessage());
    }
});
