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,

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);         ........     }     ..... }
