片段布局仅显示第一个元素（TextView）

Question

i have two fragments that show depending on whether the phone is in landscape or portrait mode. however both only show the first element but nothing else after like EditText or Buttons. Is there a fix for this?

pm_layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/portrait_message"
        android:textColor="#000000"
        android:textSize="100px"/>


    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="Enter First Time"/>

    <EditText
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="Enter Second Time"/>

</LinearLayout>

activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    android:orientation="horizontal">

    <fragment
        android:name="com.android.madpracticaltest.LM_Fragment"
        android:id="@+id/lm_fragment"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="match_parent"/>

    <fragment
        android:name="com.android.madpracticaltest.PM_Fragment"
        android:id="@+id/pm_fragment"
        android:layout_weight="2"
        android:layout_width="0dp"
        android:layout_height="match_parent"/>

    <Button
        android:id="@+id/button_main"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"/>

</LinearLayout>

在pm_layout ，您的LinearLayout的orientation="horizontal" ，其子项的宽度为match_parent ，因此您应该只看到第一个TextView
