Problem with sizes of EditText and Button in Android

I want to make the edittext width the same size as button. My EditText is currently very small.开发者_JS百科 I use relative layout.

   <TextView   
    android:id="@+id/aha4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="17dip"
    android:text="Vzdevek:"
    android:layout_below="@id/aha3" />  
     <EditText android:id="@+id/nick"       
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"     
        android:layout_below="@id/nivo"
        android:layout_toRightOf="@id/aha4"/>   
      <Button android:id="@+id/poslji"
            android:text="Pošlji"
            android:layout_height="wrap_content"
            android:layout_width="20dip"
            android:typeface="serif" android:textStyle="bold"
            android:layout_alignParentRight="true"
            android:layout_below="@id/nivo"
        android:layout_toRightOf="@id/nick"/>   

What i currently get is this: alt text http://www.shrani.si/f/1Z/x8/2lWB3f8p/device.png

What is the appropriate layout_width for edittext and button?

As you are using something like a row to show the TextView, EditText and button, you can try to use TableLayout: http://developer.android.com/guide/tutorials/views/hello-tablelayout.html

Also, make sure you set android:layout_width="wrap_content" so that the EditText use as much space as possible.

Try to assign equal weight to both button and edit text

Yeah, you're right about weight. As a hack you can do this. Not exactly right though.

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/aha4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="17dip"
        android:text="Vzdevek:" />
    <Button
        android:id="@+id/poslji"
        android:text="Pošlji"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:paddingLeft="40dip"
        android:paddingRight="40dip"
        android:typeface="serif"
        android:textStyle="bold"
        android:layout_alignParentRight="true" />
    <EditText
        android:id="@+id/nick"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_toRightOf="@id/aha4"
        android:layout_toLeftOf="@id/poslji" />
</RelativeLayout>

I managed to solve it with specifying minWidth and maxWidth for EditText.
