Android round button implementation

The circular button used in the project, which is a half-day, is implemented in sharp form with the following style code:

<Buttonandroid:id="@+id/btn_5"Android:layout_width="wrap_content"Android:layout_height="wrap_content"android:layout_gravity="Center"Android:text="@string/general_consulting"Android:textcolor="@color/white"android:textsize="@dimen/text_size18"Android:background="@drawable/bg_special_disease_circle"/>

Others do not care, background Bg_special_disease_circle.xml style code is as follows:

<?xml version="1.0"encoding="Utf-8"? ><layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item> <shape android:shape="Oval"> <corners android:radius="@dimen/size90"/> <solid android:color="@color/white"/> <size android:width="170DP"android:height="170DP"/> </shape> </item> <item android:bottom="8DP"android:right="8DP"android:top="8DP"android:left="8DP"> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true"> <shape android:shape="Oval"> <corners android:radius="@dimen/size90"/> <solid android:color="#e66b4f"/> <size android:width="162DP"android:height="162DP"/> </shape> </item> <item> <shape Android:shape="Oval"> <corners android:radius="@dimen/size90"/> <solid android:color="#f3876f"/> <size android:width="162DP"android:height="162DP"/> </shape> </item> </selector> </item> </lay Er-list>
