Android 使用AppCompactActivity膨胀类片段时出错

我看到了所有重复的问题/答案，但没有一个适合我

xml文件：

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:background="#000"
style="@style/Layout.FillWidthHeight" >


 <fragment
    android:id="@+id/fragmentListSongs"
    android:name="com.projectemplate.musicpro.fragment.ListSongsFragment"
    style="@style/Layout.FillWidthHeight"
    />
</RelativeLayout>

上面的错误是在运行时调用fragment时给出的。我检查了所有代码，没有发现任何错误。因此，请帮助我…

我认为您需要首先将该片段添加到堆栈中

 Fragment songs  = new SongsFragment();  //I don't know what you've called it
 FragmentTransaction ft = fragmentManager.beginTransaction();
 ft.add(R.id.fragment_container, songs, tag); //in your activity the content view id
 if (addToBackStack) {
  ft.addToBackStack(tag);
 }
 ft.commit();

---

片段可能不在堆栈中，因此使用

add

或

replace

而不是

show

方法我在Manifeat中应用了android:theme=“@style/theme.AppCompat.NoActionBar”，但不是worked@MayurSakhiya对不起，我写那封信的时候我想我是困了

 Fragment songs  = new SongsFragment();  //I don't know what you've called it
 FragmentTransaction ft = fragmentManager.beginTransaction();
 ft.add(R.id.fragment_container, songs, tag); //in your activity the content view id
 if (addToBackStack) {
  ft.addToBackStack(tag);
 }
 ft.commit();
