Use this layout...

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

    <TextView
        android:id="@+id/textview_amir_ghamsari"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="28dp"
        android:text="amir_ghamsari" />

    <CheckBox
        android:id="@+id/checkbox_amir_ghamsari"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textview_amir_ghamsari"
        android:layout_alignBottom="@+id/textview_amir_ghamsari"
        android:layout_toRightOf="@+id/textview_amir_ghamsari" />

    <TextView
        android:id="@+id/textview_s_masoud_emamian"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/textview_amir_ghamsari"
        android:layout_below="@+id/checkbox_amir_ghamsari"
        android:layout_marginTop="22dp"
        android:text="masoud_emamian" />

    <CheckBox
        android:id="@+id/checkbox_s_masoud_emamian"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textview_s_masoud_emamian"
        android:layout_alignBottom="@+id/textview_s_masoud_emamian"
        android:layout_alignLeft="@+id/checkbox_amir_ghamsari" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/checkbox_s_masoud_emamian"
        android:layout_marginTop="120dp"
        android:background="#46462e"
        android:hint="hint_comments"
        android:lines="5"
        android:textColor="#ffffff" >

        <requestFocus />
    </EditText>

    <ImageButton

        android:id="@+id/imagebutton_send_sms"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

You can set drawable and check if its working or not. Check this link

Please check this blog.

 <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="@drawable/check" />
<item android:state_checked="false"
android:drawable="@drawable/uncheck" />
</selector>

 <CheckBox
        android:id="@+id/checkBox1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:text="CheckBox 1"
        android:onClick="onCheckboxClicked"
