Android: Фрагмент занимает весь экран

Question

У меня есть <fragment> для деятельности карты в моем приложении для Android. Это расположение:

<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 
    <fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" 
    android:layout_height="481dp" android:id="@+id/map" tools:context=".MapsActivity" 
    android:name="com.google.android.gms.maps.SupportMapFragment" 
    /> 

    <Button 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="" 
     android:id="@+id/button" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     android:background="@drawable/round" 
     android:layout_below="@+id/map" /> 

    <ImageView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/imageView2" 
     android:layout_alignParentBottom="true" 
     android:layout_alignTop="@+id/button" 
     android:layout_alignStart="@+id/button" 
     android:layout_alignEnd="@+id/button" 
     android:src="@drawable/tick"/> 


</RelativeLayout> 

Однако, когда приложение работает, он потребляет весь экран и весь экран показывает карту и отображается запивая кнопку.

Однако, когда я проектирования приложения на этапе компоновки, он показывает правильное форматирование.

Помощь ценится. Благодарю.

Answer 1

Я использовал плавающую кнопку для лучшего и внедрения современных материалов, который удаляет все виды вопросов.

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/map" 
     tools:context=".MapsActivity" 
     android:name="com.google.android.gms.maps.SupportMapFragment" 

     android:layout_alignParentTop="true"> 
     <Button 
      android:id="@+id/button_request" 
      android:text="Request Pickup" 
      android:textColor="#FFFFFF" 
      android:textSize="24sp" 
      android:layout_gravity="center_horizontal" 

      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_margin="13dp" 
      android:background="@drawable/map_button"> 

     </Button> 
     <android.support.design.widget.FloatingActionButton 
      android:id="@+id/fab" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_margin="16dp" 
      android:clickable="true" 
      android:src="@drawable/add" 
      app:backgroundTint="#000000" 
      android:layout_gravity="bottom|end" 
      app:layout_anchorGravity="right|end"/> 

    </fragment>

Попробуйте этот макет:

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 

    <fragment 
     xmlns:tools="http://schemas.android.com/tools" 
     android:layout_width="fill_parent" 
     android:layout_height="0dp" 
     android:layout_weight="8" 
     android:id="@+id/map" 
     android:name="com.google.android.gms.maps.SupportMapFragment" /> 

    <RelativeLayout 
     android:layout_width="fill_parent" 
     android:layout_height="0dp" 
     android:layout_weight="2"> 

     <Button 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:text="" 
      android:id="@+id/button" 
      android:layout_alignParentBottom="true" 
      android:layout_centerHorizontal="true" 
      android:background="@drawable/round" 
      android:layout_below="@+id/map" /> 

     <ImageView 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:adjustViewBounds="true" 
      android:id="@+id/imageView2" 
      android:layout_alignParentBottom="true" 
      android:layout_alignTop="@+id/button" 
      android:layout_alignStart="@+id/button" 
      android:layout_alignEnd="@+id/button" 
      android:src="@drawable/tick" /> 

    </RelativeLayout> 
</LinearLayout> 

Answer 3

сделать ваш макет LinearLayout и назначить веса к нему. Что-то вроде этого.

<LinearLayout> 
    <LinearLayout 
     android:layout_weight="0.8" 
      > 
     <Fragment> 
     </fragment> 
    </LinearLayout> 
    <LinearLayout 
     android:layout_weight="0.2" 
    > 
    <Button></Button> 
    </LinearLayout> 
</LinearLayout> 

Answer 4

Так набор высоты фрагмента для wrap_content, установить выравнивание родителя верхнего и соответствует нижней части фрагмента с верхней части ImageView использованияКонтактная android:layout_above

<RelativeLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="horizontal" 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"> 
    <fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" 
    android:layout_height="wrap_content" android:id="@+id/map" tools:context=".MapsActivity" 
    android:name="com.google.android.gms.maps.SupportMapFragment" 
    android:layout_above="@+id/imageView2" 
    android:layout_alignParentTop="true" 
    /> 

    <Button 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="" 
     android:id="@+id/button" 
     android:layout_alignParentBottom="true" 
     android:layout_centerHorizontal="true" 
     android:background="@drawable/round" 
     android:layout_below="@+id/map" /> 

    <ImageView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/imageView2" 
     android:layout_alignParentBottom="true" 
     android:layout_alignTop="@+id/button" 
     android:layout_alignStart="@+id/button" 
     android:layout_alignEnd="@+id/button" 
     android:src="@drawable/tick"/> 


</RelativeLayout>

UPDATE: Это должно работать

<RelativeLayout 
      android:layout_width="match_parent"

      android:layout_above="@+id/bottom_view" 
      android:layout_alignParentTop="true" 
      /> 

      <RelativeLayout

     android:id = "@+id/bottom_view"
