First Problem:
You need to set on RelativeLayout 

<pre><code>android:bellow="@+id/message_list"
</code></pre>

2º Problem:
You need to set on ListView:

<pre><code>android:stackFromBottom="true"
android:transcriptMode="normal"
</code></pre>

Final Xml:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="#ECECFB"
 android:orientation="vertical" &gt;

 &lt;ListView
 android:id="@+id/message_list"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:stackFromBottom="true"
 android:transcriptMode="normal"/&gt;

 &lt;RelativeLayout
 android:bellow="@+id/message_list"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_alignParentBottom="true" &gt;


 &lt;EditText
 android:id="@+id/message"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" /&gt; 

 &lt;Button
 android:id="@+id/get_from_user"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:layout_marginTop="40dp"
 android:text="Gönder" /&gt;
 &lt;/RelativeLayout&gt;

&lt;/RelativeLayout&gt;
</code></pre>

blocks|key|240533|text|例如，添加|type|unstyled|depth|inlineStyleRanges|entityRanges|data|240534|android:layout_below="@id/message_list"|code-block|syntax|javascript|240535|对您的内部RelativeLayout进行约束，以约束ListView和底部RelativeLayout之间的关系，而不是将它们放置在对方的上面。|offset|length|style|CODE|240536|entityMap^0|0|0|5|E|R|8|12|E|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]|$I|V|J|W|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|X|8|@]|9|@]|A|$]]]|N|$]]

For example, add

<pre><code>android:layout_below="@id/message_list"
</code></pre>

to your inner <code>RelativeLayout</code>to constrain the <code>ListView</code> and bottom <code>RelativeLayout</code> not to lay out on top of each other.

blocks|key|671893|text|试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|671894|将此添加到您的相对布局中:+android:layout_below="@%2Bid/message_list“|671895|并将列表视图更改为wrap_content|671896|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Try this:

Add this to your Relative layout : android:layout_below="@+id/message_list"

and change your listview to wrap_content

blocks|key|671906|text|基本上是这样做的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|671907|<?xml+version="1.0"+encoding="utf-8"?>

</RelativeLayout>|code-block|syntax|javascript|671908|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Basically do this: 

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"

 android:orientation="vertical" &gt;

 &lt;RelativeLayout
 android:id="@+id/comment_layout"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_alignParentBottom="true"
 android:layout_alignParentLeft="true" &gt;

 &lt;EditText
 android:id="@+id/message"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" &gt;

 &lt;requestFocus /&gt;
 &lt;/EditText&gt;

 &lt;Button
 android:id="@+id/get_from_user"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:layout_marginTop="40dp"
 android:text="Gönder" /&gt;
 &lt;/RelativeLayout&gt;

 &lt;ListView
 android:id="@+id/message_list"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:layout_above="@+id/comment_layout"
 android:layout_alignParentLeft="true"
 android:layout_alignParentTop="true" &gt;
 &lt;/ListView&gt;

&lt;/RelativeLayout&gt;
</code></pre>

blocks|key|240573|text|试着改变这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|240574|<ListView
++++android:id="@%2Bid/message_list"
++++android:layout_width="fill_parent"
++++android:layout_height="fill_parent"
++++android:layout_weight="1"/>|code-block|syntax|javascript|240575|对此：|240576|<ListView
++++android:id="@%2Bid/message_list"
++++android:layout_width="fill_parent"

++++android:layout_weight="1"/>|240577|这应该能起作用|240578|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Try changing this:

<pre><code>&lt;ListView
 android:id="@+id/message_list"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:layout_weight="1"/&gt;
</code></pre>

To this:

<pre><code>&lt;ListView
 android:id="@+id/message_list"
 android:layout_width="fill_parent"
 android:layout_height="0dp"
 android:layout_weight="1"/&gt;
</code></pre>

This should do the trick

blocks|key|240595|text|将ListView设置在EditText布局之上。您的布局如下：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|240596|<?xml+version="1.0"+encoding="utf-8"?>
<RelativeLayout+xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>|code-block|syntax|javascript|240597|至于你的第二个问题，|240598|android:stackFromBottom="true"
android:transcriptMode="normal"|240599|到ListView|240600|entityMap^0|1|8|C|8|0|0|0|0|1|8|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|P|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|13|8|@]|D|@]|E|$]]]|R|$]]

Set your <code>ListView</code> above the <code>EditText</code> layout.
Your layout will be as below :

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="#ECECFB"&gt;

 &lt;RelativeLayout 
 android:id="@+id/bottom_layout"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_alignParentBottom="true" &gt;


 &lt;EditText
 android:id="@+id/message"
 android:layout_width="match_parent"
 android:layout_height="wrap_content" /&gt; 

 &lt;Button
 android:id="@+id/get_from_user"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_marginTop="40dp"
 android:text="Gönder" /&gt;
 &lt;/RelativeLayout&gt;

 &lt;ListView
 android:id="@+id/message_list"
 android:layout_above="@id/bottom_layout"
 android:layout_width="match_parent"
 android:layout_height="match_parent"/&gt;

&lt;/RelativeLayout&gt;
</code></pre>

And for your second problem, set

<pre><code>android:stackFromBottom="true"
android:transcriptMode="normal"
</code></pre>

to the <code>ListView</code>

blocks|key|477523|text|添加android:layout_above="@%2Bid/id_of_relative_layout"。向RelativeLayout添加一个ID，该ID包含EditText。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|BOLD|entityRanges|data|477524|entityMap^0|2|1D|1H|E|27|8|0^^$0|@$1|2|3|4|5|6|7|I|8|@$9|J|A|K|B|C]|$9|L|A|M|B|D]|$9|N|A|O|B|D]]|E|@]|F|$]]|$1|G|3|-4|5|6|7|P|8|@]|E|@]|F|$]]]|H|$]]

Add <code>android:layout_above="@+id/id_of_relative_layout"</code>. 
Add an ID to the RelativeLayout which contains the EditText.

I am developing a chat app.I want to place edittext to bottom then messages above it.But I have a problem:

<img src="https://i.stack.imgur.com/yjfXF.jpg" alt="enter image description here">

I don't want to place messages to top of edittext and button.How can I prevent this ? This is my xml:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:background="#ECECFB"
 android:orientation="vertical" &gt;

 &lt;ListView
 android:id="@+id/message_list"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:layout_weight="1"/&gt;

 &lt;RelativeLayout 
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_alignParentBottom="true" &gt;


 &lt;EditText
 android:id="@+id/message"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" /&gt; 

 &lt;Button
 android:id="@+id/get_from_user"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:layout_marginTop="40dp"
 android:text="Gönder" /&gt;
 &lt;/RelativeLayout&gt;

&lt;/RelativeLayout&gt;
</code></pre>

And I have one more question.How can I do message list system like other chat apps ? I mean when I send a message this message place to bottom of the list not to top.Now in my xml it's placing to top.Like this:
