             android:text="1337"

             />
    </RelativeLayout>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content" 
                android:id="@+id/xK1"
        android:layout_height="wrap_content" 
                android:orientation="vertical"
        android:visibility="gone">
        <include android:id="@+id/xKeyBoard" 
                    layout="@layout/keyboard">
                </include>
    </RelativeLayout>
 </RelativeLayout>

当程序在此处运行时，活动停止： mLayout.setVisibility（相对可见）

我如何解决这个问题

thx，提前

您应该只为顶部视图定义以下内容：xmlns:android=”http://schemas.android.com/apk/res/android“我认为这就是为什么会出现nullpointerexception，因为LayoutFlater无法通过层次结构找到正确的视图。

为什么你的findViewById周围有一个try-catch，你不应该在那里遇到问题？为什么你的findViewById周围有一个try-catch，你不应该在那里遇到问题？@morbak不在评论中添加代码。编辑您当前的问题并在其中添加额外的部分。@morbak尝试使用android:clickable=“true”Oupps编辑太晚了，因为我在问另一个问题@morbak不要在注释中添加代码。编辑您当前的问题并在其中添加额外的部分。@morbak尝试使用android:clickable=“true”upps编辑太晚了，因为我在问她的问题
