在颤动中从Firebase DB中的'map‘读取到ListView

FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference ref = database.getReference("your_reference");

ref.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        // 从Firebase数据库中读取数据
        Map<String, Object> dataMap = (Map<String, Object>) dataSnapshot.getValue();

        // 将数据转换为一个ArrayList
        ArrayList<String> dataList = new ArrayList<>();
        for (Map.Entry<String, Object> entry : dataMap.entrySet()) {
            String key = entry.getKey();
            Object value = entry.getValue();
            dataList.add(key + ": " + value);
        }

        // 创建一个适配器，将数据绑定到ListView上
        ArrayAdapter<String> adapter = new ArrayAdapter<>(context, android.R.layout.simple_list_item_1, dataList);
        listView.setAdapter(adapter);
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {
        // 处理取消事件
    }
});
