    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:layout_weight="100">

<ImageView
    android:id="@+id/infoinstalacion_fragment1_imgfoto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:scaleType="fitXY"
    android:src="@drawable/pld_alza" />

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignBottom="@+id/infoinstalacion_fragment1_imgfoto"
    android:background="@color/transparent">

<TextView
    android:id="@+id/infoinstalacion_fragment1_nombre_encima_de_imagen"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp"
    android:paddingRight="35dp"
    android:textSize="20dp"
    android:textStyle="bold"
    android:textAllCaps="true"
    android:textColor="@color/white"
    android:lines="2"
    android:text="Esto es un polideportivo" 
    android:gravity="center_vertical"/>

            <CheckBox
    android:id="@+id/infoinstalacion_fragment1_checkbox_favorito"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:focusable="true"
    android:button="@drawable/checkbox_favorito"/>

</LinearLayout>

try assigning weight to linearlayout and it's children like this:

<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="1"
android:orientation="horizontal"
android:layout_alignBottom="@+id/infoinstalacion_fragment1_imgfoto"
android:background="@color/transparent">

<TextView
android:id="@+id/infoinstalacion_fragment1_nombre_encima_de_imagen"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:paddingRight="35dp"
android:textSize="20dp"
android:textStyle="bold"
android:textAllCaps="true"
android:textColor="@color/white"
android:lines="2"
android:layout_weight="0.70"
android:text="Esto es un polideportivo" 
android:gravity="center_vertical"/>

        <CheckBox
android:id="@+id/infoinstalacion_fragment1_checkbox_favorito"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="true"
android:layout_weight="0.30"
android:button="@drawable/checkbox_favorito"/>

I think you should try to add this to your LinearLayout:

android:orientation="horizontal"

Although the default orientation value for LinearLayout is horizontal,in some build version of android build tools ,there's some problems if you don't set the value.
