why marginBottom not working?

Question

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/messageLayout"     android:layout_width="fill_parent"     android:layout_height="wrap_content">      <ImageView         android:id="@+id/messageSender"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_marginRight="10dp"         android:layout_marginLeft="10dp"         android:layout_marginTop="5dp"         android:layout_marginBottom="5dp"/>      <TextView         android:id="@+id/messageSenderName"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_toRightOf="@id/messageSender"         android:ellipsize="end"         android:maxLines="1"         android:singleLine="false"         android:textColor="@color/list_text_color"         android:textSize="16dp"         android:layout_marginTop="5dp" />      <TextView         android:id="@+id/messageContent"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_toRightOf="@id/messageSender"         android:layout_below="@id/messageSenderName"         android:ellipsize="end"         android:maxLines="1"         android:singleLine="false"         android:textColor="@color/codeFont"         android:textSize="13dp"/> </RelativeLayout> 

In my layout I have problem. When I set marginTop="5dp" it's fine, but when I use marginBottom nothing happens in my layout. Also when I set padding in RelativeLayout it does not work either. What is the problem here? Could you give me any solution?

Answer 1

marginBottom has no effect if you set android:layout_height="wrap_content" for <RelativeLayout>, instead set it as match_parent and check.

Answer 2

It is realy just a bug of the <RelativeLayout>, so you could try to wrap the RelativeLayout inside of a <LinearLayout> and set the margin there.
