Java RuntimeException:android.view.InflateException:二进制XML文件行#8:膨胀类片段时出错,java,android,facebook,android-fragments,Java,Android,Facebook,Android Fragments,我想将我的Google地图与FacebookSDK集成，以便通过Facebook签入位置并在相同的布局中共享，但当我将此代码添加到方法onCreate（）时，它会强制关闭并告诉错误 if (savedInstanceState == null) { // Add the fragment on initial activity setup mainFragment = new MainFragment(); getSupportFragmentManager().beg

我想将我的Google地图与FacebookSDK集成，以便通过Facebook签入位置并在相同的布局中共享，但当我将此代码添加到方法onCreate（）时，它会强制关闭并告诉错误

if (savedInstanceState == null) {
    // Add the fragment on initial activity setup
    mainFragment = new MainFragment();

    getSupportFragmentManager().beginTransaction().add(android.R.id.content, mainFragment).commit();
    myFragmentManager = getSupportFragmentManager();
    mainFragment = (MainFragment) myFragmentManager.findFragmentById(R.id.checkIn);
} else {
    // Or set the fragment from restored state info
    mainFragment = (MainFragment) getSupportFragmentManager().findFragmentById(android.R.id.content);
}

这是我的onCreate（）方法

看看如何正确地将SupportMapFragment放入片段中。

在这里的内容之后，应该有一个堆栈跟踪的“起因”部分。如果是，请张贴。如果不是，请确保您是从

FragmentActivity

继承的，而不是从

Activity

继承的。是的，我没有忘记从FragmentActivity继承。您似乎试图从

片段的onCreateView（）
中膨胀包含SupportMapFragment
的布局。虽然嵌套片段确实是可能的，但我不确定这是正确的方法。我应该怎么做？创建另一个片段以支持MainFragment，对吗？我将扩展SupportMapFragment
以添加您的业务逻辑，而不是尝试在另一个片段中包装SupportMapFragment
。或者，您可以让片段使用MapView
而不是SupportMapFragment
，将生命周期事件（例如，onCreate（）
）转发到MapView）来膨胀布局。
