Aligning all the app to the right - android

I've searched how can I align the app to the right side and the text to be written from right to left.
The only thing I've found and succeeded to do is to make the text be written from right to left by adding android:gravity="right" in the EditText and the Button, but still their sort in the line if from the left to the right.
The activity_main.xml file -
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:gravity="right"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<EditText android:id="#+id/text_message"
android:gravity="right"
android:layout_weight="1.0"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="#string/text_message" />
<Button android:layout_height="wrap_content"
android:gravity="right"
android:layout_width="wrap_content"
android:text="#string/send_button"
android:onClick="ButtonClicked" />
<Button android:layout_height="wrap_content"
android:gravity="right"
android:layout_width="wrap_content"
android:text="#string/delete_button"
android:onClick="DeleteClicked" />
</LinearLayout>
What I meant in "the sort is from the left to the right" is that the EditText is written before the "Send" button, and the "Send" button id written before the "Delete" button - so what's shown is "[____x] [Send][Delete]" and not "[Delete][Send][_____]", as I would want to.

You can use instead of LinearLayout, RelativeLayout and give your buttons some ids using
android:id="#+id/your_button_id
and then use the tags android:layout_toRightOf and android:layout_toLeftOf. In your case, something like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button android:id="#+id/delete_button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="#string/delete_button"
android:onClick="DeleteClicked" />
<Button android:id="#+id/send_button"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_toRightOf="#+id/delete_button"
android:text="#string/send_button"
android:onClick="ButtonClicked" />
<EditText android:id="#+id/text_message"
android:layout_weight="1.0"
android:layout_width="0dp"
android:layout_toRightOf="#+id/send_button"
android:layout_height="wrap_content"
android:hint="#string/text_message" />
</RelativeLayout>

Try using
android:layout_gravity
You could also just use a RelativeLayout add
android:align_ParentRight="true"

Change
android:gravity="right"
to
android:layout_gravity="right"

Buttons not getting displayed

I have the following code defined in my xml file, but I don't see the buttons getting displayed. I have read way too many posts, and pretty much tried all possible combinations, but no luck :( I'd really appreciate if someone could help me here.
<?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" >
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:gravity="center"
android:text="#string/hello_world"
android:textSize="32sp" />
<EditText
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:hint="#string/ad_desc"
android:inputType="text" />
<Button
android:id="#+id/button4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/phone" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/sms" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/maps" />
<Button
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/video" />
</LinearLayout>
I would like to see my App Name on top (Text view - #string/hello_world), right beneath it, a big box that allows me to EditText(#string/ad_desc), and beneath that, all my buttons. The button should be at the bottom, next to each other aligned in this manner - http://www.mkyong.com/android/android-linearlayout-example/ (Linear layout - Horizontal example), except I want my buttons to be at the bottom, and not at the top. Instead I see something else (Image attached)
Please feel free to ask me if you'd like me to attach anything else. I am new to Android programming, and this is totally beyond me on why it isn't working.
If you want to align your Buttons at the bottom then you are better off with a RelativeLayout as the root. Try changing it to the following and notice the properties
<?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="fill_parent" >
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="100dp"
android:text="#string/hello_world"
android:textSize="32sp" />
<EditText
android:id="#+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/ad_desc"
android:inputType="text"
androidi:layout_below="#id/textView2" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"/>
<Button
android:id="#+id/button4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/phone" />
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/sms" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/maps" />
<Button
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/video" />
</LinearLayout>
</RelativeLayout >
You may have to add some margin to the TextView and EditText for appropriate spacing but this should give you your TextView with the EditText below it and your Buttons in a horizontal LinearLayout aligned at the bottom of the screen.
Edit
Notice this property
androidi:layout_below="#id/textView2"
of the EditText and this property
android:layout_alignParentBottom="true"
Of the LinearLayout that I added.
The easiest thing is to create a new relative layout, and place the item that you need from the palette.
Or start to try and learn to make matrioska layout via xml ;)

Center Aligned Button's Text on Left

Even though I made gravity center text is still on left. I assume there must be a method to change text align
(I have tried android:textAlignment="center" too)
I've included screenshot below but dont have enough reputation to make show it.
<!-- language: lang-xml-->
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="50"
android:gravity="center"
android:text="Button" />
also tried to make it match_parent still the same problem.
EDIT for whole XML
<!-- language: lang-xml-->
<?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="match_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/etCommands"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Type a Command"
android:password="true" >
</EditText>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="100" >
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Button" />
</LinearLayout>
<TextView
android:id="#+id/tvResults"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="invalid" />
</LinearLayout>
ScreenShot
I had this problem too. Just restart your IDE.
Adding android:layout_gravity="center" to the layout for the button and have the width wrap_content should fix it.

Can't get RelativeLayout to work in Listview

I am having problems using a RelativeLayout in a ListView. I would like to have the two EditText fields one above the other, instead they completely overlap one another. I have more text to put in each row, so side by side isn't an option.
I tried taking out all extraneous code to make it work, so this is what I have:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
Here is my relative layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="#+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp" />
<EditText
android:id="#+id/room"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/time"
android:textSize="20sp" />
</RelativeLayout>
Any help would be greatly appreciated. Thank you.
Replace
android:layout_below="#id/subject"
With
android:layout_below="#+id/time"
So That EditText with id room will be below to EditText with id time.
You need to replace android:layout_below="#id/subject"
to android:layout_below="#+id/time"
Use LinearLayout for this use case
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical>
<EditText
android:id="#+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp" />
<EditText
android:id="#+id/room"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp" />
</LinearLayout>

Android text will not align to center

I have a TextView and 3 Buttons centered in a RelativeLayout, and the text in all three of them is left-justified with the parent center as the leftmost line.
I've tried changing the gravity of the TextView, Buttons, and layout but nothing is working and I'm baffled because I've never seen Android align text like this before.
I want the Button text to be centered within each Button and the top text to be center-justified.
An image of what it looks like is here: http://i.stack.imgur.com/9lHEd.png
Here's my xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_margin="20dp"
android:gravity="center_horizontal"
android:text="#string/greeting"
android:textAppearance="?android:attr/textAppearanceLarge" />
<Button
android:id="#+id/startQuizButton"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:layout_below="#+id/textView1"
android:layout_centerHorizontal="true"
android:onClick="#string/startQuiz"
android:text="#string/start_quiz" />
<Button
android:id="#+id/lessonsButton"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:layout_below="#+id/startQuizButton"
android:layout_centerHorizontal="true"
android:onClick="#string/startLesson"
android:text="#string/lessonsString" />
<Button
android:id="#+id/viewAllButton"
android:layout_width="280dp"
android:layout_height="wrap_content"
android:layout_below="#+id/lessonsButton"
android:layout_centerHorizontal="true"
android:onClick="#string/showAll"
android:text="#string/view_all" />
I included a RelativeLayout because you have it as your parent layout. However, i am not sure that it is needed. See if the following code is what you are looking for.
<?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="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Greetings" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Start Quiz" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Lessons" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="View all questions" />
</LinearLayout>
</RelativeLayout>
add in button tab android:gravity="center"...see if it works..
u need to set layout width and height to fill_parent and everything will work fine
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="your text" />
if you want to centre some text, then you could also do it this way:
<TextView
android:text="Quantity"
android:textSize="34sp"
android:textColor="#ffffff"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-light"
android:layout_centerHorizontal="true"
android:paddingTop="10dp"/>
here i have changed made it horozontal by using android:layout_centerHorizontal="true"which takes a boolean value of true or false, by making it true, it will automatically be centred on all devices
hope that helps

please help me
thanks
Try this
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="URL:"
android:layout_alignBaseline="#+id/entry"
android:layout_alignParentLeft="true"/>
/>
<EditText
android:id="#+id/entry"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/label"
android:layout_alignParentTop="true"
/>
</LinearLayout>
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:paddingRight="30px"
android:paddingLeft="30px"
android:text="Go..."
/>
</LinearLayout>
Or use RelativeLayout
Use RelativeLayout instead of Linear one and get use of android:rightOf.
As far as I understood, you cannot use such _toRightTop, _BOTTOM attributes with a linear Layout. Use RelativeLayout and all should be fine.
Use relative layout instead of linear layout.One advantage of this is that it improves your performance.if you try to search and id suing a linear layout,it will check with every component of the linear layout and try to match with its id but with relativer layout it will be faster as all elements are defined relative to each other.
