当尝试用 fragment 替换占位符容器时，我的应用程序立即崩溃。
我加载 fragment 的方法很简单:
private void loadFragment(Fragment fragment) {
getSupportFragmentManager().beginTransaction().replace(R.id.fragHolder,
fragment).commit();
}
我只是这样调用它:
Fragment fragment = new MyFragment();
loadFragment(fragment);
我要替换的容器 fragHolder 是一个 FrameLayout，它位于水平 LinearLayout 内。是否可以只将 fragment 放入特定容器中？
根据网络资源，我加载 fragment 的方式似乎没有任何问题。
如果需要，请询问更多信息。

之前还有很多，但不允许我全部发布，我假设运行模拟器时有这么多？我已经选择了与我相关的内容，但请不要犹豫，询问任何具体内容。
最佳答案
例如，只需让您的 Activity 实现 OnFragmentInteractionListener，
public class MainActivity extends AppCompatActivity implements YourFragment.OnFragmentInteractionListener
{
.
.
@Override
public void onFragmentInteraction(Uri uri) {
}
}
在您的 Activity 中也实现 OnFragmentInteractionListener 提供的方法
