                }

                Toast.makeText(MainActivity.this, msg + " Clicked", Toast.LENGTH_SHORT).show();
                        return true;
            }

        });

        }
}

以上是我想要获取短信并使用回收器视图在卡片视图中显示它们的所有代码。我在这里重复一遍，我绝对是初学者，所以请在给我解决方案的同时记住这一点我可能无法得到你的专业提示，而是请详细询问我。

Answer 1

getContentResolver>>>nonstatic member can not be referenced

这意味着，您正在尝试从静态上下文访问非静态成员，以防 getContentResolver() 是非静态方法，而您正试图从静态方法调用它，即 getSMS ()

您可以执行以下任一操作：

从 getSMS 中删除 static 或添加 static 到 getContentResolver
创建此 class 的实例以调用 getContentResolver

Answer 2

尝试将当前 context 对象传递给 SMS class

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。
