Can't set multiple controls in one line with RelativeLayout

I'm new in the world of Android development, and I'm trying to learn how to getting started from here.
Now I've followed all steps until to put the Zip Code and the Number on the same line. I don't understand how can I manage this, if I drag and drop the Number control beside the TextView the IDE put the Number above the control or to the bottom. I don't know how to explain correctly, anyway, this is an image:
and this is the source code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/relativeLayout1" />
<EditText
android:inputType="number"
android:layout_height="wrap_content"
android:id="#+id/ZipCodeEdit"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:textSize="20sp"
android:layout_width="100sp"
android:textColor="#9933FF" />
<TextView
android:text="Zip Code: "
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/ZipCodeLabel"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:textSize="20sp" />
</LinearLayout>
from the site should be like this:
what is wrong? Sorry if something is not clear, or if the category tag is wrong.

Try This
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="25px"
android:minWidth="25px" >
<EditText
android:id="#+id/ZipCodeEdit"
android:layout_width="100sp"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:inputType="number"
android:textColor="#9933FF"
android:textSize="20sp" />
<TextView
android:id="#+id/ZipCodeLabel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:layout_toRightOf="#+id/ZipCodeEdit"
android:text="Zip Code: "
android:textSize="20sp" />
</RelativeLayout>
</LinearLayout>

You should make proper use of LinearLayout, RelativeLayout, FrameLayout and TableLayout for the desired alignments.
Here is your solution.:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:minWidth="25px"
android:minHeight="25px"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/relativeLayout1" >
<EditText
android:inputType="number"
android:layout_height="wrap_content"
android:id="#+id/ZipCodeEdit"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:textSize="20sp"
android:layout_width="100sp"
android:textColor="#9933FF" />
<TextView
android:text="Zip Code: "
android:layout_width="match_parent"
android:layout_toRightOf="#+id/ZipCodeEdit"
android:layout_height="wrap_content"
android:id="#+id/ZipCodeLabel"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:textSize="20sp" />
</RelativeLayout>
</LinearLayout>
What you were doing Wrong :
You are trying to align EditText and TextView one beside another inside RelativeLayout but you've closed the relative layiut right where it started.
that makes the EditText and TextView the child view of the LinearLayout(Vertical)
As the text views are behaving as the children of Linear vertical layout there is no use of RelativeLayout hence aligning both views one below another.
One more thing when you fix that and put both the text view within RelativeLayout you have to align one view in relation with the another.
In this case:
android:layout_toRightOf="#+id/ZipCodeEdit"
Let me know if any problem.
Happy Coding

You are using a vertical LinearLayout as the parent layout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
Change android:orientation="vertical" to android:orientation="horizontal".
You can also remove the RelativeLayout as it's not really being used(nothing inside it).

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:inputType="number"
android:layout_height="wrap_content"
android:id="#+id/ZipCodeEdit"
android:layout_marginLeft="10dp"
android:textSize="20sp"
android:layout_width="100dp"
android:textColor="#9933FF" />
<TextView
android:text="Zip Code: "
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/ZipCodeLabel"
android:layout_marginLeft="10dp"
android:textSize="20sp" />
</LinearLayout>
This should fix your problem. I will explain if this works for you.

Android layout or button

I'm having a problem with an Android APP that seems related to layout. Attached image you'll see that the "Alerts" button sticks out and doesn't seem the same as the other buttons. I've replaced the image with a known good one, but the problem remains.
It was suggested it was because it is tabhost layout, but all the changes that have been recommended have not worked. So far I've tried changing the attributes from android:height and width to "wrap_content", "fill_parent", and "match_parent". Match caused another strange white space to be corrected, but this button is my last apparent challenge.
Here's the layout code, can you tell me what the problem is?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/btnSearch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/job_tab_bar_search"
android:focusable="false"
android:freezesText="false"
android:imeOptions="actionNext"
android:longClickable="false"
android:paddingLeft="17dp"
android:text="Search"
android:textColor="#color/color_text_default"
android:textSize="12dp"
android:visibility="visible" />
<Button
android:id="#+id/btnHistory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/job_tab_bar_history"
android:paddingLeft="25dp"
android:text="History"
android:textColor="#color/color_text_default"
android:textSize="12dp" />
<Button
android:id="#+id/btnFavorites"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/job_tab_bar_favorites"
android:paddingLeft="30dp"
android:text="Favorites"
android:textColor="#color/color_text_default"
android:textSize="12dp" />
<Button
android:id="#+id/btnAlerts"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/job_tab_bar_alerts"
android:paddingLeft="12dp"
android:text="Alerts"
android:textColor="#color/color_text_default"
android:textSize="12dp" />
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.32" >
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</TabWidget>
</LinearLayout>
</TabHost>

You'd think someone would have replied, in the end it was stupid simple.
The answers is:
Tabhost using tabactivity will display the background through menu items if they are re-sized. Add a color coded (html notation) color to the schema, then call that with the android:border-background construct.

How to gap between two buttons in LinearLayout

In my app two button arranged vertically in LinearLayout. i want to provide a gap between two buttons. Please provide a solution...
my layout as follows
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
>
<Button

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text = "HiText1"
/>
<Button
android:id="#+id/btnAction2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text="HiText2"
android:layout_below="#id/btnAction1"
/>
</LinearLayout>
image
thanks in advance

Add a margin (android:layout_marginTop="50dp") to the top of of the second button:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
>
<Button
android:id="#+id/btnAction1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text = "HiText1"
/>
<Button android:layout_marginTop="50dp"
android:id="#+id/btnAction2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text="HiText2"
android:layout_below="#id/btnAction1"
/>
</LinearLayout>

use android:layout_marginTop="10dp"

Use android:layout_marginTop="10.0dip" on second button.

use this code for your second button
<Buttonandroid:id="#+id/btnAction2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/cool_button"
android:text="HiText2"
android:layout_marginTop="15dp"
/>

relative layout issues/android

I am having issues with creating a menu (not menu when you click menu button -- but menu as in the welcome screen to select items). I went to ImageView and TextView float (left/right) Android and I did not solve my issue. I would like to create at least five or six options to select from on this menu class. This is my menu.xml file. Please let me know what I need to do.
The issue is that the first item appears, but the second item overlaps the first item. I been picking away with this for the last hour and cannot solve this issue.
<?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="wrap_content"
android:padding="5dp">
<TextView
android:textSize="18dp"
android:id="#+id/message_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=" Check Your Account" />
<ImageView
android:src="#drawable/ic_menu_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/icon" />
<TextView
android:textSize="18dp"
android:id="#+id/message_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=" View our Site" />
<ImageView
android:src="#drawable/ic_menu_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>
thannk you.

Why don't you use a LinearLayout (like a vertical one with severals little horizontal ones inside, each with a TextView and an ImageView) ?
Anyway, if you want to use RelativeLayout you should use something like android:layout_toRightOf, android:layout_toLeftOf, android:layout_above or android:layout_below in your xml to place your elements.
I advise you to take a look at http://developer.android.com/reference/android/widget/RelativeLayout.LayoutParams.html if you don't know those parameters.

You use a RelativeLayout but you don't place elements with reference to each other.
Example :
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button android:id="#+id/topBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Top"
android:layout_centerHorizontal="true">
</Button>
<Button android:id="#+id/leftBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Left"
android:layout_below="#+id/topBtn"
android:layout_toLeftOf="#+id/topBtn">
</Button>
</RelativeLayout>
http://developer.android.com/reference/android/widget/RelativeLayout.html

A Linear Layout would be better.
Try this and tell me if this is what you needed:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp"
android:orientation="vertical"
>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/message_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=" Check Your Account"
android:textSize="18dp" />
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_menu_add" android:layout_gravity="center_horizontal"/>
</LinearLayout>
<LinearLayout
android:id="#+id/linearLayout2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/message_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=" View our Site"
android:textSize="18dp" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_menu_add" android:layout_gravity="center_horizontal"/>
</LinearLayout>
</LinearLayout>

Android - stretched EditText above Button

I want to put a scrollable EditText above a row of buttons such that the text component fills all the vertical space left free by the buttons. This is proving surprisingly difficult, not least because the ADT is buggy: it suggests that this layout will do and it does in Eclipse but not in the real application!
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/view1"/>
<LinearLayout android:id="#id/view1"
android:orientation="horizontal"
android:layout_alignParentBottom="true">
<!-- buttons go here -->
</LinearLayout>
</RelativeLayout>
In this layout the text stretches to the full screen, as you might expect, i.e., it goes under the button but the ADT graphical layout tool shows it stopping just above the button. OTOH if you give it a wrap_content height then of course it doesn't stretch. layout_weight is of no help either.
So, is there a way? You must test your answer in the emulator or on a real device, not merely in Eclipse.
Precision: what makes me think this is not working and that the text widget extends under the buttons is the shape of the scrollbar at the bottom (see pic. below): it should be rounded at both ends and instead it looks like the bottom extends farther. If you compares its shape at the bottom with the shape it has at the top (which unfortunately I was unable to capture: it disappears too fast) it is very clearly different. OTOH the text widget boundary looks as expected. This is very confusing. Maybe just a minor bug in Android?

try this code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:id="#+id/editText1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:inputType="textMultiLine" >
<requestFocus></requestFocus>
</EditText>
<LinearLayout
android:layout_height="wrap_content"
android:id="#+id/linearLayout1"
android:layout_width="match_parent">
<Button
android:text="Button"
android:layout_weight="1"
android:layout_height="wrap_content"
android:id="#+id/button1"
android:layout_width="0dp"></Button>
<Button
android:text="Button"
android:layout_weight="1"
android:layout_height="wrap_content"
android:id="#+id/button2"
android:layout_width="0dp"></Button>
<Button
android:text="Button"
android:layout_weight="1"
android:layout_height="wrap_content"
android:id="#+id/button3"
android:layout_width="0dp"></Button>
</LinearLayout>
</LinearLayout>

This should work
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout android:id="#+id/view1" android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button android:text="Button" android:layout_weight="1"
android:layout_height="wrap_content" android:id="#+id/button1"
android:layout_width="0dp"/>
<Button android:text="Button" android:layout_weight="1"
android:layout_height="wrap_content" android:id="#+id/button2"
android:layout_width="0dp"/>
<Button android:text="Button" android:layout_weight="1"
android:layout_height="wrap_content" android:id="#+id/button3"
android:layout_width="0dp"/>
</LinearLayout>
<EditText android:id="#+id/text1" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:layout_above="#id/view1"
android:gravity="top"/>
</RelativeLayout>

I did the same thing with TextView and a Button at the bottom.I tried to put EditText in place of TextView there and it works fine for me. You can try this -
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF">
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/button"
android:text="Add New Template"
android:layout_gravity="bottom"
android:layout_alignParentBottom="true"/>
<EditText
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/editText"
android:layout_alignParentTop="true"
android:layout_above="#id/add_acronym"
/>
</RelativeLayout>
Here is the snapshot-
