Question

我遇到的问题是，每当我尝试从导航抽屉中的菜单片段（它正确地显示我的页面浏览器和列表视图）更改为Contacto片段时，它都会保留在同一页面中pageviewer和listview包括我在lay_contactofragment.xml中添加的大文本，以区分这两个片段。

以下是我点击导航抽屉中的两个片段时会发生什么的截图：

Menu Contacto

错误可能位于MainActivity.java中的片段

String[] categoria = {
            "Jeans"
    };

    int[] imagenes = {

您使用LinearLayout作为容器来添加片段，但您应该使用FrameLayout作为容器。你可以用FrameLayout替换它并尝试它是否有效吗？

此外，如果我正确理解您的要求，ViewPager和ListView应该出现在片段布局中，而不是容器视图的子项。即

将ViewPager和ListView移至lay_menufragment，并将其相关的Java代码移至FmMenu片段。这是你的第一页。
同样，将大型TextView移至lay_contactofragment片段。这是您的第二页。

因此，基本上您的主要活动只是作为容纳片段的容器，每个页面所需的视图应该添加到该特定片段本身。

更新：在主活动中添加frameLayout容器。不是碎片。

您可以在Fragment中添加LinearLayou / relativeLayout作为父级。实际上并不需要FrameLayout。

<强> lay_menufragment.xml

<?xml version="1.0" encoding="utf-8"?>

<!-- Linearlayout to display Fragments -->
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:id="@+id/container">

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="265dp"
        tools:context=".MenuActivity" />

    <ListView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/listView1"
        android:layout_gravity="center_horizontal" />

</LinearLayout>
