layout having button

<button     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="@dimen/button_size"     android:layout_height="@dimen/button_size"     android:background="@drawable/circular_button_ripple_selector"     android:textappearance="?android:textappearancelarge"     android:textcolor="@color/button_text_selector"     android:statelistanimator="@anim/button_elevation"/>

drawble/button_selector.xml

<?xml version="1.0" encoding="utf-8"?>  <selector xmlns:android="http://schemas.android.com/apk/res/android">      <item android:state_selected="true"           android:drawable="@drawable/button_selected"/>      <item android:state_pressed="true"           android:drawable="@drawable/button_pressed"/>      <item android:drawable="@drawable/button"/>  </selector>

anim/button_elevation.xml

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item         android:state_enabled="true"         android:state_pressed="true">         <objectanimator             android:duration="@android:integer/config_shortanimtime"             android:propertyname="translationz"             android:valuefrom="2dip"             android:valueto="4dip"             android:valuetype="floattype" />     </item>     <item>         <objectanimator             android:duration="@android:integer/config_shortanimtime"             android:propertyname="translationz"             android:valuefrom="4dip"             android:valueto="2dip"             android:valuetype="floattype" />     </item> </selector>

if have button in rectangular shape done here. if have circular or oval shaped button looking like,

enter image description here

to remove corners circular or oval shaped button add code .java file.

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     ...........     int buttonsize = (int) getresources().getdimension(r.dimen.button_size);     outline circularoutline = new outline();     circularoutline.setoval(0, 0, buttonsize, buttonsize);      (int = 0; < max_buttons; i++) {         button button = ......         .......         button.setoutline(circularoutline);         ........     }     ..... }
