尝试用片段替换占位符容器时，我的应用程序会立即崩溃。
加载片段的方法很简单：
private void loadFragment(Fragment fragment) {
getSupportFragmentManager().beginTransaction().replace(R.id.fragHolder,
fragment).commit();
}
我只是这么称呼：
Fragment fragment = new MyFragment();
loadFragment(fragment);
我要替换的容器fragHolder是一个FrameLayout，它位于一个水平的LinearLayout中。您是否有可能只将碎片放入某些容器中？
根据网络上的消息来源，我加载片段的方式似乎没有错。
如果需要，请询问更多信息。

之前还有更多，但是我不会允许我发布所有内容，我认为有很多我正在运行模拟器？我选择了与我相关的内容，但不要犹豫，要求任何具体的内容。

让您的活动实现OnFragmentInteractionListener，例如，
public class MainActivity extends AppCompatActivity implements YourFragment.OnFragmentInteractionListener
{
.
.
@Override
public void onFragmentInteraction(Uri uri) {
}
}
在您的活动中实施OnFragmentInteractionListener提供的方法
