Java 二进制XML文件行#318:膨胀类片段时出错

我遇到问题并显示错误：二进制XML文件行#318:错误膨胀类片段 这是我的一些代码，但我不能发布所有代码，因为堆栈溢出不允许发布超过描述的代码

她是我的延伸：

extends AppCompatActivity implements OnMapReadyCallback

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
        .findFragmentById(R.id.map);
mapFragment.getMapAsync(this);

XML

根据日志，您正在尝试使用指向null的对象。您可以在

BusinessDetail.java

文件的第48行找到问题，如下所示：

java.lang.NullPointerException
at kh.com.iknow.iknow.BusinessDetail.onCreate(BusinessDetail.java:48)

如果您无法调试该问题，您可以发布第48行中的代码，可能还有更多的代码。
