以上是我想要获取短信的所有代码，并使用recycleler视图在卡片视图中显示它们。我在这里重申，我绝对是初学者，所以请在解决问题的同时保持这一点，我可能无法得到你的专业提示，而是详细询问我。

Answer 1

getContentResolver＆gt;＆gt;＆gt;非静态成员无法引用

这意味着，您尝试从静态上下文访问非静态成员，以防getContentResolver()是非静态方法，您尝试从静态方法调用，即getSMS ()

你可以这样做：

从static 删除getSMS或将static添加到getContentResolver
创建此类的实例以调用getContentResolver

Answer 2

尝试将当前context对象传递给SMS类

SmsAdapter adapter = new SmsAdapter(this, SMS.getSMS(this.getApplicationContext()));

并将getSMS更改为：

 public static ArrayList<String> getSMS(Context context){
   .....
   Cursor cur = context.getContentResolver().query(uriSMSURI, null, null, null, null);
   .....

不幸的是我没有任何Android IDE来测试它，但它应该可以工作。
