Android height does not show shadows
I want to create a login screen by placing a linear layout containing logging items in the middle of the screen with some shadows. Even though I set the height and padding for this linear layout, I still don't get any shadows. look? Here is my layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:gravity="center|center_vertical|center_horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Willkommen Sie!"
android:id="@+id/textView2"
android:textColor="@color/primary"
android:textIsSelectable="false"
android:textSize="90dp"
android:textStyle="bold" />
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:weightSum="1"
android:clipChildren="false"
android:focusable="true" android:focusableInTouchMode="true">
<LinearLayout
android:orientation="vertical"
android:layout_width="385dp"
android:layout_height="wrap_content"
android:background="@layout/loginborder"
android:layout_weight="0.30"
android:gravity="center"
android:padding="8dp"
android:elevation="8dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name"
android:id="@+id/textView3"
android:textSize="32dp"
android:textIsSelectable="false" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="textPersonName"
android:ems="10"
android:id="@+id/editText2" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Kennwort"
android:id="@+id/textView4"
android:textSize="32dp" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="textPassword"
android:ems="10"
android:id="@+id/editText" />

I don't believe you can get the elevation above the text to create shadows for the letters. The closest you can do is create a kind of floating mark by setting an opaque background and height directly to the text view; eg,
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Name"
android:id="@+id/textView3"
android:textSize="32dp"
android:background="#FFFFFFFF"
android:elevation="8dp"
android:textIsSelectable="false" />
or, to add some dimension, you can use an old CBT (Computer Learned) trick to compensate for contrasting text behind body text (which should be opaque):
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="1.5sp"
android:layout_marginTop="1.5sp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Willkommen Sie!"
android:id="@+id/textView2shadow"
android:textColor="#33000000"
android:textIsSelectable="false"
android:textSize="90dp"
android:textStyle="bold" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Willkommen Sie!"
android:id="@+id/textView2"
android:textColor="?colorPrimary"
android:textIsSelectable="false"
android:textSize="90dp"
android:textStyle="bold" />
</FrameLayout>
