加载片段时应用程序崩溃

【问题标题】：Application Crash on loading fragment加载片段时应用程序崩溃
【发布时间】：2018-08-26 04:18:28
【问题描述】：

当尝试用片段替换占位符容器时，我的应用程序立即崩溃。

我在片段中加载的方法很简单：

private void loadFragment(Fragment fragment) {
getSupportFragmentManager().beginTransaction().replace(R.id.fragHolder, 
fragment).commit();
}

我就是这么称呼的：

Fragment fragment = new MyFragment();
loadFragment(fragment);

我要替换的容器 fragHolder 是 FrameLayout，它位于水平 LinearLayout 内。是否可以只将碎片放入某些容器中？

根据网络上的资源，我加载片段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，但是我不允许我全部发布，我假设有这么多，因为我正在运行一个模拟器？我已经选择了与我相关的内容，但请不要犹豫，询问任何具体的内容。

【问题讨论】：

  • 在崩溃期间分享 logcat 错误
  • @ヅfix 请看更新。

标签： java android android-studio android-fragments


【解决方案1】：

例如，让您的活动实现 OnFragmentInteractionListener，

public class MainActivity extends AppCompatActivity implements  YourFragment.OnFragmentInteractionListener
{
.
.
@Override
public void onFragmentInteraction(Uri uri) {

}
}

在你的活动中实现OnFragmentInteractionListener提供的方法

【讨论】：

  • 关于我的主要活动？当我去实现时，我只能选择实现 Myfragment1.OnFragmentInteractionListener、MyFragment2.OnFragmentInteractionListener 等。
  • 我必须为每个片段单独实现这个吗？
  • OnFragmentInteractionListener 是为活动完成的默认回调实现 - 片段交互，对于要与活动交互的片段，您将需要它，否则删除片段内的接口和对它的所有引用
  • 总是乐于提供帮助！
