PS：我是新手:)

【问题讨论】：

  • 分享fragmentA的代码
  • @Younas Bangash 添加:)

标签： java android xml android-layout android-fragments


【解决方案1】：

从您的布局 XML 中删除以下内容：

<fragment
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:name="android.support.v4.app.DialogFragment"
    android:id="@+id/fragment2" />

你不能像在布局中那样使用DialogFragment。

您的方法名称中还有一个错字，以后会导致类似的问题：

public View onCreatewView

应该是

@Override
public View onCreateView

在两个片段中。

【讨论】：

  • 是的，确实有错字，但这并不能解决错误：s
  • 编辑添加另一个问题。
  • 我无法删除片段，因为 main.class 找不到片段。我将 DialogFragment 更改为 Listfragment 并且活动开始了。片段仍在加载，因此存在问题内存左右。为什么我不能在布局中使用 DialogFragment？
