layout of activity

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/mainlayout" android:background="#6ed19e"> <relativelayout     android:layout_width="match_parent"     android:layout_height="match_parent"     android:id="@+id/backgroundlayout"     android:background="#6ed19e">     <imageview         android:src="@drawable/bgpattern"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:id="@+id/patternimageview"         android:scaletype="centercrop" />     <textview         android:text="já estamos em muitas cidades\nestamos na sua?"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:id="@+id/manycitylabel"         android:textcolor="#ffffff"         android:textsize="25dp"         android:width="20dp"         android:gravity="center"         android:textstyle="normal" /> </relativelayout> <listview     android:layout_width="match_parent"     android:layout_height="match_parent"     android:id="@+id/locationslistview"     android:background="#ffffff"     android:visibility="invisible" /> 

menu

<?xml version="1.0" encoding="utf-8" ?> <menu xmlns:android="http://schemas.android.com/apk/res/android"       xmlns:tools="http://schemas.android.com/apk/res-auto"       android:layout_width="match_parent"       android:layout_height="wrap_content">   <item android:id="@+id/locationsearch"         android:layout_width="match_parent"         android:layout_height="wrap_content"         tools:showasaction="always"         tools:actionviewclass="android.support.v7.widget.searchview"/> </menu> 

the iconified stuff did programatically because when change xml didn't work

edit if set background color of searchview

the search doesn't fit entire space. why?

you can following:

hide app bar in oncreate() so:

// hide ui first actionbar actionbar = getsupportactionbar(); if (actionbar != null) {     actionbar.hide(); } 

in layout file set background green (or colour), add searchview , set background searchview white so:

<android.support.constraint.constraintlayout      ...     android:background="#00ff00"     ...>      <android.support.v7.widget.searchview         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:background="#fff" />     ...     <textview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="hello world!"         app:layout_constraintbottom_tobottomof="parent"         app:layout_constraintleft_toleftof="parent"         app:layout_constraintright_torightof="parent"         app:layout_constrainttop_totopof="parent" />      .... </android.support.constraint.constraintlayout> 

i pretty sure other search interface code shall work. need redirect event calls.
