Question

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <RelativeLayout
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" >

    <Button
        android:id="@+id/bb"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:drawableLeft="@drawable/bb"
        android:drawablePadding="5dp"
        android:text="bb" />

    <Button
        android:id="@+id/cc"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_below="@id/bb"
        android:drawableLeft="@drawable/cc"
        android:drawablePadding="5dp"
        android:text="cc" />

</RelativeLayout>

there should be two buttons in the screen with same width in the center. but there is nothing but blank screen x.x I'm not that new in developing android, but sometimes I miss little details which give me a lot of headache. sorry for disturbing

Replace the RelativeLayout that wraps your Buttons with a LinearLayout like this:

<LinearLayout
    android:orientation="horizontal"
    android:layout_width="100dp"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true" >

<Button
    android:id="@+id/bb"
    android:layout_weight="1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:drawableLeft="@drawable/bb"
    android:drawablePadding="5dp"
    android:text="bb" />

<Button
    android:id="@+id/cc"
    android:layout_weight="1"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_below="@id/bb"
    android:drawableLeft="@drawable/cc"
    android:drawablePadding="5dp"
    android:text="cc" />

</LinearLayout>

RelativeLayout does not support weight.
