compile 'me.alexrs:wave-drawable:1.0.0'

import android.app.activity; import android.graphics.color; import android.os.bundle; import android.view.menu; import android.view.menuitem; import android.view.view; import android.view.animation.interpolator; import android.widget.adapterview; import android.widget.arrayadapter; import android.widget.imageview; import android.widget.spinner; import me.alexrs.wavedrawable.wavedrawable;   public class mainactivity extends activity {  private wavedrawable wavedrawable;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          imageview imageview = (imageview) findviewbyid(r.id.image);  wavedrawable = new wavedrawable(color.parsecolor("#8e44ad"), 500);         imageview.setbackgrounddrawable(wavedrawable); interpolator = new linearinterpolator();  wavedrawable.setwaveinterpolator(interpolator);         wavedrawable.startanimation();  }       @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }      @override     public boolean onoptionsitemselected(menuitem item) {         // handle action bar item clicks here. action bar         // automatically handle clicks on home/up button, long         // specify parent activity in androidmanifest.xml.         int id = item.getitemid();         if (id == r.id.action_settings) {             return true;         }         return super.onoptionsitemselected(item);     }  }
