Explain what is wrong

    1 answer 1

    Replace

     android:shape="ring"

    on

     android:shape="rectangle"

    To round corners, use corners :

     <corners android:bottomRightRadius="16dp" android:bottomLeftRadius="16dp" android:topRightRadius="16dp" android:topLeftRadius="16dp"/>

    Full markup:

     <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="#eeff0000" /> <corners android:bottomRightRadius="16dp" android:bottomLeftRadius="16dp" android:topRightRadius="16dp" android:topLeftRadius="16dp"/> </shape>
    • Not displayed - Ahillesius
    • In your my_round_button markup, white is set, if the background is white, then it will seem like it is not displayed. Copy into your my_round_button all the markup code that I dropped, and then it will be displayed. - McDaggen
    • did so as written - Ahillesius
    • If you do not install the background button, it is displayed? - McDaggen
    • if not installed, then it is displayed - Ahillesius 8:49 pm
