Alignment in android - android

I am new to android, currently designing a User Home Page. please let me know how to align UI controls like - Button , EditText, etc to left/right/center in Linear and List Layout. button code eg.

you can achieve this by using set gravity of layout . here i have one xml file in which i have two image button and one text view . Here i set text view in center . So its fits to all devices.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageButton
android:id="#+id/Back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:src="#drawable/back"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:layout_marginTop="2dp"/>
<LinearLayout
android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical">
<TextView
android:id="#+id/txtName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/white"
android:textSize="18sp"
android:textStyle="bold"
android:singleLine="true"
android:text="Top 100"/>
</LinearLayout>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:id="#+id/Playing"
android:visibility="invisible"
android:src="#drawable/nowplaying"
android:layout_gravity="center_vertical"
android:paddingTop="3dp"/>

How to set text in center of text view

I am making the list view in which I have a image view and to its left I have to align the TextView which should have text in the center of it not the bottom of it. I have set the gravity but its only looking good in the design but when I run my app and data is fetched in list view then the text gets set in the bottom .
I will show you what I mean by this.But first let me show you how I am doing to align this
<RelativeLayout
android:id="#+id/block_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/pin" />
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignBaseline="#+id/iv_address"
android:layout_alignBottom="#+id/iv_address"
android:layout_marginLeft="3dp"
android:layout_toRightOf="#+id/iv_address"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
</RelativeLayout>
and this is how I am getting this
And this is what I want it to be
as you can see in the second picture I want this type of adjustment. and in design preview it is showing me design just like it is expected. But When I run the app it just showing me text like i showed you in picture one.
Please tell me what i am doing wrong and How to constrict this not to get out of allignment.
Replace whole code with :
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:android:drawableLeft="#drawable/pin"
android:drawablePadding="10dp"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
You can add a drawable icon
<TextView
android:drawableLeft="#drawable/..."/>
Replace your TextView with this:
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignTop="#+id/iv_address"
android:layout_alignBottom="#+id/iv_address"
android:layout_marginLeft="3dp"
android:layout_toRightOf="#+id/iv_address"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
Use LinearLayout Instead of RelativeLayout as acheiveing something like this is pretty easy in LinearLayout
<LinearLayout android:layout_width="match_parent"
android:layout_height="150dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/iv_address"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="3"
android:src="#drawable/andro"/>
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="7"
android:text="Hello World"
android:gravity="center"/>
</LinearLayout>
Try LinearLayout instead of RelativeLayout. because its easy to align.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="#+id/block_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dp"
android:orientation="horizontal"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:id="#+id/iv_address"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/logout" />
<TextView
android:id="#+id/row_address"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_marginLeft="3dp"
android:gravity="center|center_vertical"
android:text="Address Goes here"
android:textColor="#AAAAAA" />
</LinearLayout>

How to make the ellipsize textview and imageview show correct

I'm working on a layout file. This layout requires that the icons should always after the single line TextView. If the TextView is too long,then the TextView is ellipsize and the icons should be shown.Such as:
situation1: [[textview][icon1][icon2] ]
situation2: [[textview......][icon1][icon2]].
I have found the similar case in here, but it doesn't work for me.
My current code is something like this:
<RelativeLayout
android:id="#+id/parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:gravity="left">
<!-- icon show here -->
<LinearLayout
android:id="#+id/icons"
android:paddingLeft="5dp"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:gravity="center_vertical|left">
</LinearLayout>
<!--text show here-->
<TextView
android:id="#+id/text"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_toLeftOf="#id/icons"
android:singleLine="true"
android:ellipsize="end"
android:gravity="left"/>
</RelativeLayout>
The LinearLayout is used to add icons when fetch data from server. Android's layout preview is like above situation,but the apk runs on device like this this:
situation1: [ [textview][icon1][icon2]]
situation2: [[textview......][icon1][icon2]].
I'm really confused. Anybody has some ideas about this situation? Thanks in advance.
I found the code works fine after Android 4.3(include 4.3,I haven't test 4.2),it doesn't work below Android 4.3.The reason I think is that different Android systems parse these layout params in different ways.Such as some version think the parent container layout's params is more important than the child view.
Finally, I got my stupid situation.But it works.I will give you code:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<!--text show here-->
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ellipsize="end"
android:singleLine="true"
android:layout_weight="1" />
<!-- icons show here -->
<LinearLayout
android:id="#+id/icons"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_gravity="center_vertical"
android:orientation="horizontal">
</LinearLayout>
</LinearLayout>
<TextView
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:layout_gravity="right"/>
</LinearLayout>

How to place a button at a position little above the bottom in android

I need to place a button at the bottom of screen, leaving some space below it.
In other words I am using these two attributes for my button -
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp"
but the margin attribute wont work when I use alignParentBottom and the button sticks at the bottom only. Please tell me how to place it a little above the bottom .
Here's the xml
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:background="#drawable/board"
android:layout_marginLeft="10dp"
android:layout_marginRight="60dp"
android:layout_marginTop="15dp"
android:layout_marginBottom="10dp">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="Type of Lesion"
android:textColor="#8B0A50"
android:layout_marginTop="40dp"
android:id="#+id/disease_listheader_textview"
android:drawableBottom="#drawable/underline"/>
<ListView
android:id="#+id/disease_listview"
android:layout_below="#id/disease_listheader_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:divider="#drawable/divider"
android:layout_marginLeft="40dp"
android:layout_marginBottom="50dp"
android:cacheColorHint="#00000000"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/disease_search_button"
android:layout_centerHorizontal="true"
android:background="#drawable/disease_search_btn"
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dp"/>
</RelativeLayout>
just make change in relative layout height attribute value to fillparent like
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
.................../>
hope this help you
Can you try this?
Replace the Button tag with the one mentioned below. I am trying to wrap the button in another dummy layout
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:paddingBottom="20dp">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/disease_search_button"
android:background="#drawable/disease_search_btn"
android:layout_marginBottom="20dp"/>
</LinearLayout>
This runs just the way you wanted
<RelativeLayout android:id="#+id/relativeLayout1" android:layout_width="match_parent" android:layout_height="fill_parent">
<Button android:text="Button" android:id="#+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_marginBottom="20dip"></Button>
</RelativeLayout>

Android: Image Button icon and text

I'm having trouble with the layout of my navigation bar. I was hoping to have an icon with text underneath it all centered in the button. Currently when the icon is drawn in it pushes the text off the page. The only way to get it back is by using android:drawablePadding="" (from here) using a negative value but it looks like this:
My xml looks like this:
<LinearLayout android:id="#+id/navbar"
android:layout_alignParentBottom="true" android:gravity="center"
android:layout_width="fill_parent" android:background="#001"
android:layout_height="60dip" android:layout_weight="1"
android:orientation="horizontal">
<Button android:layout_height="fill_parent" android:id="#+id/navhomebtn" android:enabled="false"
android:textColor="#FFF" android:background="#drawable/navbuttonselected" android:drawableTop="#drawable/homeicon"
android:drawablePadding="-40dip"
android:text="Home" android:layout_weight=".25" android:layout_width="0dip" />
<Button android:layout_height="fill_parent" android:id="#+id/navsearchbtn"
android:textColor="#FFF" android:background="#drawable/navbuttons"
android:text="Search" android:layout_weight=".25"
android:layout_width="0dip" />
<Button android:layout_height="fill_parent" android:id="#+id/navfavbtn"
android:textColor="#FFF" android:background="#drawable/navbuttons"
android:text="Favorites" android:layout_weight=".25"
android:layout_width="0dip" />
<Button android:layout_height="fill_parent" android:id="#+id/navlistbtn"
android:textColor="#FFF" android:background="#drawable/navbuttons"
android:text="Loans" android:layout_weight=".25"
android:layout_width="0dip" />
</LinearLayout>
The way your buttons look you might as well use a relativelayout containing a textview and an imageview. Then set the relativelayouts clickable attribute to true and the background attribute to your navbuttons drawable.
Another way is to use the drawableLeft/Right/Top/Bottom attributes like this:
<Button
android:id="#+id/home_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/home_icon"
android:background="#drawable/nav_background"
android:text="Home"/>
To set text and image for button you may do like this:
<?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">
<Button
android:text="Button"
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="#drawable/icon"></Button>
</LinearLayout>
Hope, it helps you!

Android: How to make all elements inside LinearLayout same size?

I would like to create a dialog to display a video title and tags. Below text I would like to add buttons View, Edit and Delete and make these elements same size. Does anyone know how to modify .xml layout file in order to make elements inside LinearView same size?
The current layout file looks like 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
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/txtTitle" android:text="[Title]" >
</TextView>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/txtTags"
android:text="[Tags]" >
</TextView>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btnPlay"
android:text="View">
</Button>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btnEdit"
android:text="Edit">
</Button>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/btnDelete"
android:text="Delete">
</Button>
</LinearLayout>
</LinearLayout>
I would appreciate if anyone could show the solution by modifying the pasted file content.
Thanks!
Use android:layout_width="0px" and android:layout_weight="1" on the three Buttons. That says the buttons should take up no more than 0 pixels, but the three of them should split any extra space between them. That should give you the visual effect you wish.
Another way is to make android:layout_width="fill_parent" and android:layout_weight="1" this will also works fine!!!
Use LinearLayout with your desired weightSum and create elements with equal layout_weight. Here is an example ...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="5">
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ic_share_white_36dp"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ic_search_white_36dp"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ic_event_note_white_36dp"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ic_brush_white_36dp"/>
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:src="#drawable/ic_menu_white_36dp"/>
</LinearLayout>
So, the weight sum of all elements is 5. Here is the screenshot ...
Note that, Google Material Design icons are used. Hope this is helpful.
