Button Border Not Showing

I try to put a border for a button in android but unfortunately I can't see the button border.
Drawable File 👇
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="12dp" />
<stroke android:width="3px" android:color="#7E8082" />
</shape>
</item>
</selector>
XML 👇
<Button
android:id="#+id/btn_signup"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_marginTop="122dp"
android:background="#drawable/bg_signup"
android:fontFamily="#font/poppins_semibold"
android:text="Create an Account"
android:textAllCaps="false"
android:textColor="#color/black"
app:layout_constraintTop_toBottomOf="#+id/btn_login" />

You don't need to use a custom drawable, just use a MaterialButton:
<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
app:strokeColor="#7E8082"
app:strokeWidth="1dp"
app:cornerRadius="12dp"/>

Don't use a selector for single option use shape directly
bg_signup
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#cdcdcd"/>
<corners
android:radius="4dp"
/>
<stroke
android:width="1dp"
android:color="#000"
/>
</shape>

use Style attribute instead of android:background="#drawable/bg_signup"
make a custom style then call it android:style="#style/bg_signup"

Button color not change... ( Android)

I was working on a project I can create a round button and set the gradient color but when I use it in Button background the color not changed.
rounded_shape.xml
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:startColor="#9bbbc1"
android:centerColor="#456268"
android:endColor="#456268"
android:angle="270" />
<corners
android:radius="25dp" >
</corners>
</shape>
Button in Xml
<Button
android:id="#+id/btn1"
android:layout_below="#+id/edttxt1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="80dp"
android:layout_marginTop="2dp"
android:layout_marginRight="80dp"
android:layout_marginBottom="2dp"
android:background="#drawable/rounded_shape"
android:padding="12dp"
android:paddingTop="2dp"
android:paddingEnd="2dp"
android:paddingBottom="4dp"
android:text="Analyse"
android:textAllCaps="false"
android:textColor="#android:color/white"
android:textSize="20dp"
android:textStyle="italic"></Button>

Try it in rounded_shape.xml :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
<shape android:shape="rectangle" >
<corners android:radius="12dip" />
<stroke android:width="1dip" android:color="#333333" />
<gradient android:angle="-90" android:startColor="#333333" android:endColor="#555555" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="12dip" />
<stroke android:width="1dip" android:color="#333333" />
<solid android:color="#58857e"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="12dip" />
<stroke android:width="1dip" android:color="#333333" />
<gradient android:angle="-90" android:startColor="#333333" android:endColor="#555555" />
</shape>
</item>
</selector>

The AppCompat library helps with bringing modern theming to your app on all Android versions, so change Button to androidx.appcompat.widget.AppCompatButton:
<androidx.appcompat.widget.AppCompatButton
android:id="#+id/btn1"
android:layout_below="#+id/edttxt1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="80dp"
android:layout_marginTop="2dp"
android:layout_marginRight="80dp"
android:layout_marginBottom="2dp"
android:background="#drawable/rounded_shape"
android:padding="12dp"
android:paddingTop="2dp"
android:paddingEnd="2dp"
android:paddingBottom="4dp"
android:text="Analyse"
android:textAllCaps="false"
android:textColor="#android:color/white"
android:textSize="20dp"
android:textStyle="italic”/>
