Android button design - with selector (2021)

If you have a project that makes use of

    implementation 'com.google.android.material:material:x.x.x'

and after checking the button design you tried adding selectors to change the button's color when it is pressed like this

 <Button
        android:id="@+id/btn_six"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Button Six - button selector"
        android:layout_margin="8dp"
        android:background="@drawable/button_selector"
        android:textColor="@android:color/white"
        android:textStyle="bold"/>

You need to consider adding

    app:backgroundTint="@null"

to see the effect of the background change. Thus the Button would then be something like this

    <Button
        android:id="@+id/btn_new"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        android:background="@drawable/button_selector"
        android:onClick="btlClick"
        android:text="Button 2021"
        android:textColor="@android:color/white"
        android:textStyle="bold"
        app:backgroundTint="@null"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/textView" />

To recap, there 4 files that require change to get the selector work in this example are:

1- The layout that contains the button:

• should use the drawable button_selector.xml and set the backgroundTint to @null

        android:background="@drawable/button_selector"
        app:backgroundTint="@null"

2- Add the 3 files

    - button_selector.xml
    - button_shape.xml
    - button_shape_pressed.xml
