Solution 1:

If You dont want click on that Image, Then you can use drawableRight property for EditText..

android:drawableRight="@drawable/icon"

If you want click then use below code.

<?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="wrap_content" >

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Enter search key" />

    <ImageButton
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:src="@drawable/search"
        android:layout_centerVertical="true"
        android:layout_margin="5dp"
        android:text="Button"/>

</RelativeLayout>

Solution 2:

If you want such layout and also image as clickable then you can do something like this

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true" >

    </EditText>
     <ImageView
        android:id="@+id/imageView1"
        android:padding="5dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/editText1"
        android:layout_alignBottom="@+id/editText1"
        android:layout_alignRight="@+id/editText1"
        android:src="@drawable/ic_launcher" />

</RelativeLayout>

Output:

Solution 3:

In Material, there is that underline under EditText. In most applications the icons appear inside that underlining.

enter image description here

For that purpose, just use padding

android:paddingEnd = "@dimen/my_button_size"

Don't forget paddingRight for sub 4.2 versions.

<RelativeLayout ....>
   ...
   <EditText
   ...
   android:id="@+id/my_text_edit"
   android:textAlignment = "viewStart"
   android:paddingEnd = "@dimen/my_button_size"
   android:paddingRight = "@dimen/my_button_size"
   .../>

   <ImageButton 
   ....
   android:layout_width="@dimen/my_button_size" 
   android:layout_height="@dimen/my_button_size"
   android:layout_alignEnd="@id/my_text_edit"
   android:layout_alignRight="@id/my_text_edit"/>
   ...
</RelativeLayout>

It will limit the text to the image and the image will not overlap the text, however long the text may be.

Solution 4:

My solution will fit all screen sizes without the editText going "behind" the imageButton. This also uses android resources, so you do not need to provide your own icon or string resource. Copy and paste this snippet wherever you would like a search bar:

   <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="horizontal">
  
   <EditText
        android:layout_margin="8dp"
        android:id="@+id/etSearch"
        android:hint="@android:string/search_go"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"/>

    <ImageView
        android:id="@+id/ivSearch"
        android:background="@color/transparent_black"
        android:padding="2dp"
        android:layout_width="wrap_content"
        android:layout_margin="8dp"
        android:src="@android:drawable/ic_menu_search"
        android:layout_height="wrap_content"
        tools:ignore="contentDescription" />

</LinearLayout>
